FRUITS AND NUTS

After about twenty years of waiting, I happened to look at the ground and see a pine cone. The only pine tree nearby is a Korean pine (Pinus koreanensis) that I planted that many years ago, a tree that liked its new home and has soared, in that time, to fifty feet in height. My problem with the tree is that all it has done is grow; I planted the tree for its pine nuts.

A few years ago I did see a few cones way up near the top of the tree. Would the cones fall, carrying down the nuts, or would the nuts fall out, to be lost in the high grass? Would squirrels make all this moot?

I picked up the cone and clawed back its scales to see if any nuts were hiding within. Zut alors! Nuts! Most nuts need some curing before tasting good so I laid the cone in the sun for a few days.

Tasting was next. First they needed to be cracked out of their shells, which was surprisingly easy with a pair of pliers. The first two nuts cracked were well filled and yielded delicious nuts. The next ten nuts, which comprised the rest of the harvest, when cracked, yielded nothing.

Many Nut Pines

The pine nuts you see for sale are generally one of the piñon pines native to the Southwest, the pignolia native to Italy and other Mediterranean countries, or Chinese white pine (Pinus armandii). In fact, though, a number of pine species provide edible nuts.

One of my favorites, the Digger pine (P. sabiniana), yields nuts the size of lima beans and is native to the foothills of the Sierra Nevada mountains. Driving west down those mountains many years ago, I came to a screeching stop (well, not really screeching) upon seeing the giant cone of this tree on the ground. I picked it up and must have provided entertainment, perhaps elicited fear, in passerbys seeing some guy smashing open a pine cone on the guard rail.

My Korean pine is a dead ringer for our native white pine, the latter of which does not yield edible nuts. Korean pine is only one of a number of nut pines that grows well in cold winter climates, such as Zone 5 here in this part of New York’s Hudson Valley. Swiss Stone pine (P. cembra) and Siberian pine (P. sibirico) are also reliable nut-producers for cold climates, but are very slow growing.

Many other pine species potentially could produce pine nuts outside their native range, though their adaptability to very cold winters climate is not thoroughly tested. The closely related Colorado Pinyon (P. edulis) and Singleleaf Pinyon (P. monophylla) pines are bushy trees that become flat-topped with age. I planted a Singleleaf pine years ago and though it tolerated the cold winters here, it’s annual growth measured in inches. With the slow growth and lack of nuts, I eventually tired of it.

Over the years, my pinetum (yes, that is a word) has expanded. A Lacebark pine ((P. bungeana), after five years or so in the ground, has finally taken off and is growing over a foot a year. This species is especially worth growing also for its decorative bark, which is a patchwork of muted colors.

Blanks

Back to the blank shells borne by my Korean pine. One possibility is that this pine needs cross-pollination from another tree of the same species to bear nuts or, at least, to bear them well. The cone that I found lying on the ground was pretty soggy and might have been lying there for a year or more. Perhaps nuts within dried up and/or rotted away. I subsequently found three more soggy cones, all devoid even of nut shells.

I recently planted pollinators for the pine. They’re small, but after a couple of years of nurturing are finally growing well, the largest of the two now two feet tall. I’ll report back, hopefully in less than 20 years.

Survival of Fittest and Tastiest

On the bountiful side of the fruit and nut ledger this year are my tree fruits, especially the more common tree fruits. (Berries and uncommon tree fruits such as persimmon, mulberry, and cornelian cherry always do well here.) Winter and then spring weather were all  perfect for a good set of fruit. Once that usually fraught time in fruit growing was passed, Mother Nature took over and the trees naturally shed fruits that had been poorly pollinated or insect ridden. That lets a tree channel its energies into making bigger and more flavorful the fruits that remained hanging on branches.
Pear fruitlets before thinning
Nature’s aim in growing fruit is to make it appealing to all sorts of animals that incidentally spread the seeds as they eat the fruit. We humans are more discerning (would “finicky” be a better word?) when it comes to fruit quality. So once that natural fruit drop, “June drop” as it is appropriately called, is finished, we step in to remove even more fruit.

Pruning branches, on which some fruit would have been borne, in late winter and early spring already did some of that work. This week it was time to finish the job, by hand. This means putting some distance between each fruit and its neighbor, about five inches, always saving the largest and most pest free of the lot. Hand thinning would be tedious with smaller fruits, such as cherries and plums, so fortunately is unnecessary with them.

I ended up with a bucketful of cute apple and pear fruitlets. Cute, but into the compost they went where heat and time would cook any insect or disease pests lurking within that might have awakened to attack next year’s crop.

ROSES AND STRAWBERRIES AND — OH NO! — HONEYBERRIES

Roses, Oh Yes

I bake really good bread, but “man can’t live by bread alone.” Sometimes, you’ve got to “stop to smell the roses.” Enough with the quotations! But back to the roses.
Roses in a vase
A love of roses has crept up on me over the years, due mostly to changes in kinds of roses available. Up until about 30 years ago, hybrid teas were pretty much the only roses on the block. These plants’ gangly stems are each capped by a vividly colored, fairly stiff, formal blossom whose petals wrap together into a pointy peak. You see where I’m going: hybrid teas are ugly, to me at least. 

Also available were grandiflora and floribunda roses. Grandifloras are like hybrid teas, except their stems end with clusters of a few, but smaller, blossoms. Floribunda roses have even larger flower clusters of even smaller flowers. Despite being bushes more full with flowers than hybrid teas, grandiflora and floribunda flowers are still rather prim and proper except for their traffic-stopping colors.

  Then so-called species and old-fashioned roses entered the scene, roses that are as nature made them or only slightly hybridized. These roses constitute broad groups, but generally, what they have going for them are more subdued — think pastel — colors and more blowsy blossoms on more heavily branching, fuller-bodied, shrubs. 

The downside to species and old-fashioned roses, even if you like their blossoms and their growth habits, is that many bloom only in the spring. Hybrid teas pump out blossom after blossom all summer long.

Rose d'Ipsahan blossom

Rose d’Ipsahan

Enter Rose de Rescht, my first old-fashioned rose, given to me by a local, fellow gardener. Ann told me that this rose variety had soft pink flowers and heavenly scent. She was right about the appearance and fragrance, wrong about the name. After years of sleuthing, I’ve identified the rose as Rose d’Ispahan, probably originating in Persia but first discovered in a garden in Isfahan, Iran, renowned for its gardens and roses.

If I had to grow only one variety of rose, Rose d’Ispahan would be the one, for the beauty of its flowers, for its intense fragrance, for its cold-hardiness, for its lack of large thorns, and for its pest resistance. And that’s even though it blossoms only in spring. (It does so over a long period, though.)

But I don’t have to grow only one variety of rose. My other favorites are some of rose breeder David Austin’s varieties which combine the pest resistance and repeat blooming of modern roses with the blowsy, fragrant, pastel colored blossoms and full-bodied shrubs of old fashioned roses. My currant, and perhaps all-time, favorites are Lady of Shallot and, in my opinion needing a more euphonious name, Golden Celebration.

Both sport yellow — no, Golden! — blossoms, some apricot in those of Lady of Shallot, and a rich yellow, all contained in a petal-filled cup-shape in those of Golden Celebration. Another of my favorites, Lady Judi Dench, never woke up in spring a year ago; perhaps it was the cold, perhaps something else.

I also grow another David Austin Rose, LD Braithewaite, with deep red blossoms and dark green, slightly reddish leaves. Not my favorite as far as appearance but this rose is very cold hardy and pumps out tons of blossoms almost all season long.

And Strawberries, Oh Yes

Strawberries and rosesOn to strawberries. I’m growing three kinds: the Pineapple Crush variety of white alpine strawberries; the Earliglow variety of garden strawberry; and a few varieties of vescana strawberries, which are hybrids of garden and alpine strawberries. This also is the order, starting with the best, of flavor for the three types.

Why do I grow anything but the best? Because alpines are so small that it’s hard to fill a bowl with them. I grow vescanas, for the first time this year, because I never grew them before.

The Earliglow berries taste good and do quickly fill a bowl, ideally yielding one quart of berries per plant over the course of the season. Except this year, a problem has surfaced. Leather rot is a fungal disease (Phytophthora cactorum) that rears its ugly head — infected berries that taste bitter and have white patches that turn brown — usually following excessively wet periods from late spring to early summer, which is odd because weather has been on the dry side. Also odd because I’ve never seen the problem here before.
Strawberry leather rot1
Which brings me back to vescana and Pineapple Crush. Both are very disease resistant, and vescana berries are almost as big as garden strawberries, so I’m thankful to have them, even if they do taste like canned strawberries.

And Honeyberries, Oh NO!

After three weeks of hanging on (the berries, not me), honeyberries, which are edible honeysuckles, are ready for a fair tasting. I wrote previously about the awful flavor of this new fruit and was instructed to let the berries hang till dead ripe.
Honeyberries
The berries sampled this year were so ripe that each had to be plucked from the branch with my palm facing upwards beneath the berry; a mere touch would cause ripe ones to drop.

Rat-a-tat-tat-tat-tat (a drum roll). First to be tasted was the variety Solo. Reaction: spit it out quickly. Tart with bad flavor. Second fruit tasted was Sugar Mountain Blue. Also spit out, but not quite as quickly. And finally, Sugar Mountain Eisbär. Although retained in the mouth and having a hint of sweetness, this one, like the others, had bad flavor.

The flavor of honeyberries is allegedly like a mix of blueberry and raspberry. Not so! If you have space, plant blueberries or raspberries instead.

GOD’S BEST BERRY?

First Good-Tasting Berries of the Season

Strawberries, the aptly named variety Earliglow, are ripe, which means it’s time to start crawling for fruit. That’s one thing I don’t like about strawberries.

Strawberries, clockwise from left, vescana, garden, and alpine

Strawberries, garden, vescana, and alpine

Another thing I don’t like about strawberries is that, although they’re perennial plants, a bed needs replanting after about 5 years. By then, viruses, fungal diseases, weeds, and just plain aging have finally taken their toll. The decline creeps up slowly so is not all that obvious. And no, you shouldn’t replant in the same spot where the now pest-ridden bed was, but in a new location. And don’t replant with rooted runners from those old plants, but with new, certified disease free plants.

Any bad feelings I had dissolved away as I tasted my first berry of the season. I almost agreed with Izaak Walton, in the 16th century, “Doubtless God could have made a better berry, but doubtless God never did.” (He had never tasted our native highbush blueberries.) Aside from good flavor, strawberries bear quickly, their first or second season in the ground, and are the first good-tasting, fresh berries of the season.

I planned ahead, this being my planting’s fifth year, ordering plants for spring planting and setting them in a relatively weed free bed in my vegetable garden, two rows running up and down a three-foot-wide bed with a foot between plants in the rows. Right after harvest, out goes the old bed, to be given an inch dressing of compost and then in go leek and/or fall cabbage and cauliflower plants.

Strawberries, new and old bed

Strawberries, new and old bed

I’ll keep the new bed productive for its five years with annual renovation, a brutal affair that begins with, right after berries have been harvested, lopping off and raking up all the leaves, etc., etc. No need to dwell on this now, while enjoying berries from the old bed.

A Strawberry Better than a Strawberry

Conventional garden strawberries (Fragaria X ananassa) aren’t the only strawberries on the block. I’ve written previously about another kind of strawberry, alpine strawberry (Fragaria vesca), which is a totally different species than garden strawberries. Sure, they also have their downsides: they’re small, typically dime size; they’re very soft and perishable; and after two or three years, plants get old at their center so either need to be divided, or chucked, and new plants started.

Pineapple Crush alpine strawberries

Pineapple Crush alpine strawberries

On the plus side, new plants are fairly easy to start from seed, similar to growing tomato transplants except needing more patience. And the plants bear their first season. Not only bear their first season, but bear more or less continuously all season long.

Alpine strawberries are very resistant to pest problems. And birds? No problem if you grow Pineapple Crush, the white ones. The birds ignore them. Pineapple Crush berries also have the best flavor, with more than a hint of pineapple.

I’ve been testing people’s reactions to tasting my white alpine strawberries. Without fail, within seconds of putting one in their mouth, a person’s eyes light up and they exclaim “Wow.”

Trying for the Best of Both Worlds

Okay, alpine strawberries are small. You’re not going to fill your freezer with these strawberries. Hmm, how about combining the best of garden strawberries and the best of alpine strawberries? It’s been done. The hybrids are called vescanas, botanically Fragaria X vescana, a combining of their parents’ botanical names.

As a fan of alpine strawberries, how could I resist searching for these hybrids? I found some and, last spring, planted them, the varieties Annelie, Rebecka, Sara, Florika, and, not sounding very appetizing in name, S-228. The alpine genes express themselves in disease resistance and bearing fruit more or less continuously through summer and into fall. Garden strawberry struts its genes in the hybrids’ fruit size which, for the hybrids is much larger than the alpine strawberries but smaller than the garden strawberries. 

The fruits are red but red alpine strawberries, which are more common than white alpine strawberries, might have been used in the breeding.

Most evident in coming upon my small patch of these vescanas is how fast they are spreading. There are runners all over the place! I usually frown on such a habit because keeping my strawberry bed from becoming overcrowded necessitates pinching off all runners except for those needed to put rooted plants in place to replace old plants.

Vescana strawberries

Vescana strawberries

Making lots of runners is billed as an asset for the vescanas, allowing them to be grown as so-called meadow strawberries, the meadow needing neither renovation nor mulching. I’ll let my plants wander off somewhere by themselves and see how they fare.

You may have noticed that there’s an elephant in the room; up till now there’s been no mention of flavor. I was saving that. Quoting from a journal article by the breeders of Rebecka, this variety has “fine aroma.” Perhaps in Sweden where that variety was bred. Or, quoting from the patent for Florika, “The variety is a vescana-type strawberry plant characterized by its capability of developing exceptionally rich and fine flavor of medium sized fruits.” Perhaps in Germany, where this variety was bred.

Here in New York’s Hudson Valley, I thought the fruits were good, but nothing special, and surely not as especially good as my Pineapple Crush white alpine strawberries.

Now that I think of it, Izaak Walton’s very high praise of strawberries might have been more warranted than I first noted. So-called garden strawberries are relative newcomers on the garden scene, originating as a chance hybrid in the 18th century. Prior to its arrival, the strawberries that were grown or harvested from the wild were mostly the musk strawberries (Fragaria moschata, very delicious) and alpine strawberries.

I haven’t said “wow” upon tasting any of my vescana strawberries.

A BRIGHT FUTURE

As Good As It Gets

You might think that writing about good weather would tempt the fates. I’ll thumb my nose at the fates and go ahead and write that this spring is the best spring, gardenwise, ever in all the decades since I’ve been gardening. The flowers have been more vibrant with color and, it seems, also in greater profusion. The air has been particularly fragrant, especially now with the intoxicating aroma of black locust blooms following closely on the heels of autumn olive’s sweet scent.
Apple tree in bloom
My fruit trees are most thankful for this spring’s beneficence. In all the years of growing fruit here on the farmden, never has the landscape been so brightened by snowballs of white blooms of plum and pear trees, pinkish blossoms of apples, and peaches’ pure pink blossoms.

The now-fallen petals are no cause for wistfulness, because those clusters of flowers have now morphed into clusters of fruits

Why this Year?

What makes for such a glorious spring? The weather, of course, both this spring’s in addition to last winter’s and even last spring’s. Let’s first go back to last spring’s weather effects.

During spring 2020 the weather warmed going into April, coaxing flower buds on fruit trees to swell. Then, towards the end of that month and into May, a number of nights saw temperatures that nipped life from many flowers, then open, especially the 22° temperature on April 23rd and then subfreezing temperatures on May 9th, 13th, and 14th. (All this information handily recorded and passed onto my computer via Sensorpush sensors I have at two locations outdoors and one location in the greenhouse.) 
Peach fruitlets
Prelude to the present season began with a relatively mild winter, for which peach flower buds, which suffer damage at around minus 15°, were especially appreciative. And this spring has seen more or less gradually warming temperatures with — and this is most important — no late, damaging frosts. Buds for a current spring’s blossoms develop the summer of the previous year. Seeds in developing fruits produce a hormone that suppresses flower bud formation, so a heavy crop one year means a lighter crop the following year, and vice versa, all other things being equal. Last year’s late frosts knocked out much of the potential fruit crop so this year the trees did what they do, compensating for last year’s loss with more blooms.
Asian pear espalier
Fruit trees can afford to lose a certain number of flowers to cold each year. For instance, each flower bud of an apple tree unfolds to five flowers, and only 5 percent of those flowers need to set fruit for a full crop of apples. Furthermore, a temperature below 32° doesn’t always cause damage; just how much damage ensues depends on the the growth stage of flower buds and how cold it gets. Using apples, again, as an example, when their buds have expanded just enough to hint at the five flowers within (the “tight cluster” stage), 27° will kill 10 percent of them, 21° will kill 90 percent of them. More details for apples and other fruits can be found here.

Another variable is that temperatures can vary a little at various points within a tree, which can be important at these critical temperatures.

Not Yet Home Free

This auspicious spring is not a call for me to just sit back and wait for the delicious bounty to hang on the branches awaiting my picking. My work is cut out for me.

One job, to begin soon, will be thinning the fruit, that is, removing lots of them. In addition to upping the chances for a good return bloom and harvest next year (remember the seeds and the hormones), fruit thinning lets the trees channel more of their energy resources into fewer  fruits. The result: Fruits that remain are larger and more flavorful. Fruit thinning also lessens the chance of limbs breaking under the the load of too many fruits, and lessens pest problems. Two apples touching each other provide good cover for the larvae of codling moths to burrow into the fruits to become the classic “worm in the apple.”

Apple fruitletsCommercially, tree fruits are thinned with chemical sprays but I’ll be thinning by hand. The plan is to reduce the number of fruits to one per bud, leaving the largest and most pest-free, and allowing remaining fruits to sit no closer than about a half a foot apart along branches. Larger kinds of fruits are the ones that need thinning, which is nice because it would be very tedious to thin small fruits, such as cherries. Winter pruning removes some branches with fruit buds, so also contributes to reducing the load, as does trees’ natural shedding of some excess fruits.
Pear fruitlets
Another job, which began a few weeks ago, is keeping an eye out for and protecting fruits from insects and diseases — particularly problematic on a less than perfect site such as here on the farmden. All of the common tree fruits, except for pear, are very prone to these problems throughout much of eastern North America.

On a backyard scale, the problems are few but serious, in some cases serious enough to eliminate almost the whole crop or render it inedible. The major culprits are plum curculio, codling moth, apple maggot, oriental fruit moth, brown rot, apple scab, fire blight, and cedar apple rust. Not to mention deer and squirrels.

My tack is to take a multi-pronged approach, with some spraying (mostly organic), nurturing the soil (lots of mulch and compost) and the plants (pruning and fruit thinning), fostering beneficial insects with plantings that encourage their presence and with careful choice and limited amount of sprays, trapping pests (hanging fake apples, Red Delicious, with sticky Tanglefoot in trees), and possibly bagging individual fruits. See Grow Fruit Naturally for more about these approaches.

Even if there is “many a slip ‘twixt the cup and the lip,” every fruit grower has to be an optimist.

FRUITFUL FUTURES

Making the Best of It

Eek! Mice (or rabbits)! Not the animals but the damage they have wrought. The bark on virtually all my pear grafts of last year has been nibbled off enough to kill the grafts.

Once I calmed down, I realized that all was not lost. All the chewing was above ground level, leaving a small amount of intact bark still in place. The plants aren’t dead, just their portions above the chewing. The near-ground portions could be grafted again.

(Most fruit trees neither come true from seed nor root readily from cuttings, so are propagated by grafting a scion — a short length of one-year-old stem — of the desired variety onto a rootstock. The rootstock is the same kind of plant as the scion variety and could be a seedling or a variety developed for special rootstock purposes. My nibbled trees are pear trees, Highland, Blake’s Pride, and other varieties, each grafted on a rootstock named Old Home X Farmingdale 87, which dwarfs the trees’ final height to about half that of a full-size pear tree, as well as induces it to yield its first fruits sooner.)

Damaged rootstock

Damaged rootstock

Crouched way down at ground level would be a tough position for grafting, not to mention trying to keep dirt and debris off the cut surfaces. So I dug up each plant for “bench grafting,” so named because it’s done at a bench or, more generally, upright and in the comfort and better light of indoors.

My graft of choice for these wounded plants is the whip graft. It’s a simple graft, especially for apple and pear; I typically expect 95+ percent “takes.” With a well-honed, preferably straight-edged (and preferably single-bevelled) knife, I make a smooth, sloping cut about 3/4-inch long on the rootstock. Typically, I would make the cut longer but there’s not that much viable stem above-ground. 

Making the cuts on rootstock and scion

Making the cuts on rootstock and scion

Next, I take a scion of similar thickness to the rootstock, although this is not all-important, and make a similarly smooth, sloping 3/4-inch long cut.

If the cuts are secured face to face and then sealed against moisture loss, cells at the cuts start to multiply, eventually knitting the two pieces together and joining their vascular tissue. If the two plant pieces are not matching in thickness, success can still be achieved if just one side of the two of them is aligned. A piece of rubber, either a cut open rubber band or a bona fide grafting rubber, keeps cut edges of scion and rootstock intimate, and then the wound is sealed with Tree-Kote or similar tree wound material, or Parafilm tape.

Keeping the roots moist and the plants indoors for a couple of weeks speeds growth of new cells. After that, the plants will go outdoors, either potted up or planted in the ground.

The Downside to Low Grafting

Grafting so low on the plant does have its downsides. For one thing, a certain amount of rootstock stem above ground level is needed for the dwarfing effect. For full effect, grafts are usually made 6 to 12 inches above ground level.

Also, if a graft is very low on a plant so that over the years it gets covered with soil, the scion is could eventually root. At which point the dwarfing and other benefits of the rootstock are lost.

On the plus side, if any of my grafts fail, the still viable rootstock will undoubtedly send up a new shoot, which can be grafted next spring — and done well above ground level.

So How Do You Get a Rootstock?

The way to get a rootstock is to buy one (ha, ha). But how does as nursery make, for instance, an Old Home X Farmingdale 87 pear rootstock if pears (and most other tree fruits) are so hard to root and don’t come true from seed.

Rootstocks are bred or selected to impart special characteristics to the tree for which they provide roots and a short length of stem — very short stems in the case of this week’s pear grafts. Another characteristic that might be sought in a rootstock is ease of propagation, perhaps even by cuttings.

Whereas a pear variety such as Blake’s Pride is propagated from mature, fruiting wood, a rootstock might be propagated from juvenile wood, that is, wood that that has never grow to maturity. All plants are easier to multiply from juvenile wood. Near the base of a plant that has been raised from seed, the wood retains its juvenility, so a seed-propagated rootstock variety that was repeatedly cut back would provide stems that were juvenile and could be rooted as cuttings.

And there are other ways to coax new plants from an existing plant, such as tissue culture and stool layering. Maybe something about these methods at another time.

Fruitful Near Futures

Even grafted higher atop a rootstock that imparts precocity, my pear grafts aren’t apt to yield their first crop for a few years. My Nanking cherry bushes (Prunus tomentosa), on the other hand, are slated to have bright red cherries arching their stems to the ground in a couple of months or so.

A profusion of Nanking cherries!

The cherries are small, but are very juicy with a refreshing flavor that combines that of sweet and tart cherries. Another plus for these plants is that they are more or less free of pest problems, requiring no care on my part beyond picking the fruit. Read more about them in my book Landscaping with Fruit.

No need to ignore the bushes until payday because payday is also right now, visually. Along the length of my driveway, the hedge of Nanking cherries has turned into a cloud of dense, slightly pink, white flowers. This time of year it’s not uncommon for a biker or walker to stop and ask the name of the plants. “Nanking cherry!”

OUTDOOR MAPLES AND INDOOR KUMQUATS

Sap Season

Get your taps in. It’s syrup weather. Maple syrup. At least here in New York’s Hudson Valley, the sunny days in the 40s with nights in the 20s that are predicted should get the sap flowing.

  I say “should” because I haven’t yet checked sap buckets that I hung out on the trees a few weeks ago when winter temperatures suddenly turned warm; it was sap weather back then. That day was hopeful: I drilled holes an inch and a half deep, lightly hammered in the spiles, hung buckets, and attached covers over the buckets. Frigid days and nights that descended soon after that kept sap flow in abeyance.

  My “sugar bush” amounts to only three sugar maple trees. I used to have four, but a large tree that was a truly magnificent representative of its species began an irreversible path to its death. My older sugar mapel“Maple decline” is a disease complex brought on by some combination of drought, soil compaction, road salt, root damage, and air pollution. Upper branches are usually the first to go, and once decline begins, secondary fungi and insects speed the process along.

  I’m not sure about my tree, though, because its lower branches were the first to go. Also, the tree grows along the back edge of my property, where it’s been shielded from those usual causes for decline.

  One more contributor to decline is overtapping. I plead not guilty. My fading tree was larger than the 8 or10 inch minimum diameter for tapping, and I only tapped it once, when the tree, it turned out, was already going downhill. The lack of sap flow was what prompted me to see all this. And then I noticed many rows of sapsucker holes in the bark.

Long story short: The tree became firewood.
Maple syrup buckets
My three other, healthy maples might yield me only a quart of finished syrup. The reasons? One quart is enough for me, so I’m tapping only one of them. Also, they’re relatively young. I planted those three trees about 25 years ago, and they’re now only about 8 inches in diameter.

I highly recommend planting trees, for their beauty, for what food they might offer, and for the mere satisfaction of watching the plants grow. Especially if they are small when planted. Small trees also establish quickly to require less aftercare, often soon outgrowing their initially larger compatriots. Those three maple trees? From one perspective, it seems like a long time ago that I dug holes and set the saplings in the ground; from another perspective, it seems like I planted them, walked away, then turned right around to find that these young ‘uns have grown into bona fide trees!

Birch Sap

I may end up with more sap than planned, but not maple sap. Along with the three sugar maples I planted way back when, I also planted three river birches (Betula nigra). They grow, appropriate to their name, in a wet area just out of a swale through which water runs in spring, each a clump of a half dozen or so sturdy trunks reaching skyward to about 35 feet.

Maple might be the heaviest sap producing tree, but it’s not the only kid on the block. Many people tap their black walnut trees. Call me provincial, but black walnut syrup, much as I love the nuts themselves, has no appeal me even though I’ve never tasted it.

Birch syrup though . . . mmm. Never tasted that one either, but it sounds good. Three birch taps should offer an ample amount for tasting.River birches

What a Funny Name

  I don’t need to see the small, pebbly-skinned, orange orbs on grocers’ shelves to know that it’s kumquat season. My own Meiwa kumquat is looking very pretty, with a good crop of fruit staring out from their backdrop of glossy, forest-green leaves. I’ve trained the plant as a “standard,” that is, as a miniature tree with a crown of branches perched atop a four foot trunk.
Kumquat houseplant
 The present crop is my best ever, and traces its success back to last spring. In previous years, I was too timid with pruning. And pruning is necessary, every year. Pruning keeps the plant from growing disproportionately large for its pot -– or my house — and coaxes growth of new, fruiting wood.

The roots also get pruned each year to make space for new potting soil for root growth and nutrients. I laid down the plant and pot to easily slide out the root ball. After slicing an inch or two of roots and potting soil from all around the outside of the root ball, back into the pot the plant went, with new potting soil packed in the space between the shaven root ball and the inside edge of the pot. The seemingly brutal treatment took place last year just as the garden awoke in yellow blossoms from daffodils.
Repotting kumquat
As soon as weather warmed, new sprouts began to grow. By midsummer, the plant was fragrant with blossoms. By late summer, little, green fruits were forming which, with careful watering, survived the environment change as the plant moved indoors in October. The plant stood at attention in a sunny window in the cool bedroom for weeks, and a couple of months ago, the fruits started turning orange. They are now ripe and delicious!

THANKS

I’d like to highlight, today, what makes this blog possible. 

First of all, it’s you, readers. The positive feedback I get is very rewarding. I’ve had great opportunities — academically and “in the field” — to learn about growing plants and caring for the soil, and have put all this into practice for decades. My hope is that in entertaining you with all this, your tomatoes, apples, zinnias, and all the rest grow healthier and tastier or prettier. I appreciate the positive (even the sometimes negative) comments from you all.

Second, if you’ll look at the bottom right corner of my blog posts (or scroll way down near the end on a mobile device), you’ll see some banner ads. Nothing flashy or moving or obnoxious in any other way. Just simple links to a few advertisers.

These seven advertisers are special; these are companies whose products I stand behind. I’ve used them and can attest to their quality.

Take, for instance, Raintree Nursery and Cummins Nursery. I’m a “fruit nut” (and a “nut nut”) and, except when I propagate my own plants, these two nurseries are my go-to nurseries for fruiting trees and shrubs.

Raintree Nursery stands out for the wide variety of common and uncommon fruits they offer, everything from apples to jujubes to musk strawberries to wintergreen to hardy passionfruits. All top quality plants.

Cummins Nursery also offers top quality plants, trees in this case. Steve Cummins, the present owner, started the nursery with his dad, Jim, and other family members. Back in the 20th century, when I worked in research for Cornell University, Dr. Jim Cummins also worked there. For many years, he was the rootstock breeder. (A rootstock, on which a Honeycrisp, Mutsu, or other variety of fruit is grafted in order to propagate it, can impart special qualities to the resultant tree, such as early production, eventual tree size, pest resistance, and tolerance to poor soil conditions.)

So I turn to Cummins Nursery if I’m interested in a common (vs. uncommon) fruit tree on a special rootstock, with many, many varieties of fruit to pick from. Or if I want to purchase a rootstock to graft myself. Or if I want a scion of any one of the many, many different varieties of fruits grown at Indian Creek Farm, the pick-your-own farm they run adjacent to the nursery.

You’ll note that Raintree Nursery is in Washington state and Cummins Nursery is in New York state. No matter. These nurseries are selling named varieties of fruit plants. A McIntosh apple grown in Washington state is genetically identical to that variety grown in New York state, so will have the same cold-hardiness, pest resistance, and other characteristics. Of course, a particular season’s weather, wherever the tree is planted, could influence flavor and texture.

Essential, Quality Tools

If you grow fruit plants — or vegetables or ornamentals or houseplants — you’re going to need certain tools. Glance down, then, to my next three advertisers: OESCO (“Oesco” is the acronym for “orchard equipment supply company)”, ARS (the exclusive agent for ARS pruning tools), and Scythe Supply Co.

Whether it’s pole pruners, pruning saws, or most other pruning tools, ARS are among my favorites, and especially for hand shears. The ARS website shows the complete line of ARS tools, as well as where you can purchase them.
ARS web page
One place for many of those pruning tools, ARS or otherwise, is OESCO. And much more. Trowels, all sorts of shovels, hedgers, sharpeners, grafting knives and sealants, stuff for making trellises, and, of course, many kinds of hand pruning shears.
OESCO web page
Scythe Supply Co is where I purchase all my scythe blades, sharpening stones, peening tools, and, originally, my snath and grips (I’ve since made these last two parts myself, when needed). You might think a scythe to be an archaic tools. Not so; it works even early mornings without waking the neighbors and in ground too wet or grass too high for a mower. Swinging a scythe is a meditative, first-class exercise.
Scythe Supply Co, webpage
My property was originally a mere 3/4 of an acre. Besides my home, vegetable garden, and fruit trees, I was able to dedicate a portion of that property to a mini-hay field, where I let the grass grow high and then periodically scythed it as food for my compost pile. It was decorative and functional. (Okay I did encroach on the actual hayfield bordering my 3/4 of an acre; I eventually bought it and now have a bona fide hayfield, portions of which I scythe.)

Two More Essentials

You might wonder, “What’s with Bobbex and Sensorpush?”, the last two ads on these blog pages?”

Bobbex webpage

In the past couple of winters as Daisy and, especially Sammy, matured beyond their super energetic puppy stages, 

 

deer have taken note and become bolder. My initial testing of Bobbex, a deer repellent, seemed promising. I’ve since become amazed at its effectiveness. Deer are here, but not feeding on any of my sprayed plants. And spraying is only needed once a month.

I’ve waxed enthusiastic about Sensorpush many times here on this blog. Basically, it’s a one inch square by 1/2 inch device that you place wherever you want to know the current and historical temperature, relative humidity, barometric pressure, dewpoint, and vapor pressure deficit. There’s one in my greenhouse, and it can alert me if the temperature goes above or below whatever temperature specified. SensorpushThe one on my garden gate is especially useful in spring and fall, when frosts threaten. As soon as the snow melts, my third Sensorpush will go beneath the pile of leaves protecting a fig tree I planted outdoors to monitor winter temperatures there. (Much more about this at a later date.)

So there you have it: seven companies whose products, in my opinion, make for better gardening or farming.

Get Ready for Spring

Are you interested in having a weedless garden this season? Learn how, at my upcoming WEEDLESS GARDENING webinar. The system I’ll talk about also makes more efficient use of water, conserves valuable soil organic matter, allows earlier planting in spring, and doesn’t disrupt beneficial fungi and other friendly soil organisms. Starting a new garden? Here’s the fastest way to get the soil prepared and plants growing.

I’ll cover all this, and more, in the webinar, and allow plenty of time for questions. The webinar costs $35 and runs from 7-8:30 pm on Monday, February 22, 2021.

FROM GROCERS’ SHELVES TO MY FLOWER POTS

Exotic, tropical fruits are turning up more and more frequently on grocers’ shelves these days: dates, papayas, guavas, and others. I look upon these fruits opportunistically, because within each lies dormant seeds that can be coaxed to become exotic, if not beautiful, indoor plants that might even provide a delicious fruit harvest. Such plants provide a break from the humdrum of spider plants, philodendrons, and Swedish ivies. 

Seeds of tropical fruits usually germinate best if planted as soon as the fruits are eaten. Cold-climate fruits, in contrast, have innate inhibitors that prevent seed germination until they feel that winter is over.

So all that’s necessary to grow most tropical fruits is to wash their seeds and sow them in potting soil, using the old rule of thumb of burying a seed to twice its depth. And then wait.

DELICIOUS, BUT HARD TO SAY

  I have harvested fruit grown from the seed of a grocery store bought pineapple guava, also known as the feijoa (pronounced FAY-HO’-A, from the generic part of its unwieldy Latin name, Feijoa sellowiana, recently change to Aca sellowiana). The fresh seeds, scooped from the fruit, germinated and grew.
Feijoa fruit
Feijoa seems to me an ideal plant to grow. Even outdoors where it’s native, the tree is small, so does not mind being kept five foot high in a pot which can be carried indoors during our frigid winters. The plant is subtropical rather than tropical, so can stand a bit of cold, down to about 10 degrees Fahrenheit. 

Feijoa has leaves which are shiny and dark green on their upper surfaces, and felt-like and silvery on their lower surfaces. My plant spends winter decorating a sunny, south-facing window in a cool room in my house. The flowers’ stamens are arranged in a tuft like a red bottlebrush, and the petals are thick, purple and white. Those petals are very edible and very delicious, with a sweet, pineapple-minty flavor.

But best of all is the fruit itself. Beneath the thin skin is a gelatinous center with a spicy pineapple flavor. My feijoa plant hasn’t provided sufficient harvest to satisfy my feijoa-ish needs.

A LONG TIME TO WAIT FOR A DATE

The waiting period for a date fruit can be a long time, even a long time for the seed to germinate. But stop for a moment and think about deserts, where dates are native. Should a date seed send up a leafy shoot with the first hint of moisture? Of course not. The dry desert air would dehydrate the sprout in short order. When a date seed germinates, first its thick taproot grows straight downwards, seeking permanent moisture, long before even a small sprout appears aboveground.

I once planted some date seeds (first making sure they came from unpasteurized dates). Knowing that I would have a long wait before the first sprouts emerged, I planned to watch the roots grow to keep myself from becoming too impatient. I put an inch of water in the bottom of a peanut butter jar, slid a tube of rolled-up blotting paper (watercolor paining paper would probably also work well) into the jar, and then “planted” the date seeds halfway up the jar, pressed between the glass and the paper. 

As predicted, the roots appeared and thrust downwards before there was any sign of a shoot. When I eventually became bored watching the progress of the roots, I planted the seedlings in potting soil.

Leaves finally did poke up through the soil, an event that was far from dramatic. Each emerging seedling looked like a green toothpick stuck into the soil. In time, the “toothpicks” did unfurl into a succession of fan-like leaves which would match any ordinary houseplant for beauty and tolerance of neglect. 

Fruit production from a homegrown date palm is well-nigh impossible. The plant grows slowly. Climate here in northeastern U.S. is suboptimal, to say the least. And only female plants produce fruit, so enough plants would have to be grown to flowering size to ensure at least one male (for pollination) and one female (for fruit).

PA-PA-PAPAYA

One winter day a number of years ago, I planted seeds from a papaya fruit I had just eaten. Having seen papayas growing wild throughout the tropics, I assumed they would not be hard to grow. I scooped the seeds from the fruit, washed them to remove their gelatinous coating, and sowed them immediately. 

Growing papayas proved as challenging as growing dates. In this case, not only were the seeds slow to germinate, but the young seedlings were extremely fragile and subject to damping-off. I nursed a single survivor beyond this wimpy initial stage, and, in time, it began to grow robustly.

In the tropics, papayas are short-lived trees that often bear their first fruits as early as eleven months after seed is sown. My papaya tree was outgrowing its one-foot-diameter pot when warm weather arrived, so I decided to plant it outside and hope for fruit. Imagine the astonishment of my neighbor, who grew up in Florida, when he saw a tropical papaya tree in my garden! 

Unfortunately, my plant succumbed to the first fall frost before it had a chance to fruit. Fruiting would have been chancy anyway, because papaya plants come in various combinations of sexes. Some plants have only male flowers; others only female flowers; and still others have bisexual flowers. Papaya have been known to switch their sex under certain conditions. To fruit, my single plant would have needed bisexual flowers, which remained so.

  The feijoa, date palm, and the papaya take their place in the long line of avocados, prickly pears, tree tomatoes, kumquats, lemons, tangerines and other forgotten grocery store plants that once were and, in some cases, still are part of my indoor jungle.

ALMOST LIKE SUMMER

Fresh Veggies

When I was a child, it seemed that winter vegetables were mostly peas and diced carrots, conveniently poured frozen out of plastic bags into pots of boiling water. Yuk! Winter notwithstanding, my backyard garden still offers plenty of fresh winter vegetables. Let’s have a look. Kale, of course, looks unfazed by snow and plummeting temperatures. Not only does it look unfazed; it also tastes very delicious.

More surprising is the endive that I planted back in August, then covered beneath a “tunnel” of clear plastic and slightly insulating row cover held aloft by metal hoops in late October. Temperatures about a week ago went as low as -8° Fahrenheit! Thanks to the additional insulation from almost a foot of snow, now melted, the endive is still lush and tasty.

The rest of winter’s fresh garden vegetables are not in the garden. Most are in plywood boxes in cold storage, first in my mudroom, then moved out to my cooler. vegetables of winter(The cooler is an insulated room cooled with an air conditioner that has been tricked, with a device called CoolBot, into bringing the temperature down just below 40° F.) One box houses Hakurei turnips, Watermelon radishes, and Daikon radishes picked around the middle of December.

The same day I pulled the turnips and radishes, I also dug up leeks, now nestled into another box. With snow cover, both leeks and turnips probably would survive winter out in the garden, but reaching into a box is easier than chopping through ice and snow out in the garden to get at these vegetables.

Yet another box has a few heads of cabbage, also harvested that day in December. Lopping off the outer leaves, which anyway were looking ragged and slug-eaten, cuts water loss from the tight heads and keeps them fresh. One more box is packed full of napa type Chinese cabbages, good for “Asian slaw” or stir fry.

Most years I would have braids of onions also. Not this year. Crop failure. All the onions, both direct-seeded and grown from my transplants, didn’t grow large enough to bother storing. The problem was a clog, too long undetected, in the water line to the seasonal irrigation pump at, evidently, a critical time in onion bulb development.

(I also have a 400 square foot greenhouse packed full of fresh, growing lettuce, mustard greens, arugula, celery, claytonia, kale, chard, and mâche, with a little fresh dill, cilantro, and parsley. But that’s a whole other story.)

Summer Berries

I may be addicted to blueberries. I now eat them pretty much every morning year ‘round. That’s fresh blueberries beginning at the end of June, and frozen ones from mid-September on. I pace myself. The frozen blueberry season opens with about 70 bags (each bag about 5 cups) in the freezer, enough to keep us “berry happy” on into June.
Blueberries, frozen and defrosted
I highly recommend planting blueberries. They are easy to grow organically, the plants are beautiful, and the berries are very healthful and taste great. They’re also easy to freeze: Just spread them on a tray until frozen, then pack them into bags. Their two main requirements are suitable soil, easily made so, and protection from birds, with netting. Each bush will net you 8 pounds, or more, of berries.

Thawed in the refrigerator, the berries taste as good as fresh ones. Or maybe I believe that only because in late December it’s been so long since I’ve had a fresh blueberry.

Olfactory Romance

Man cannot, of course, live by bread alone. I could use some fragrance, some olfactory hint of spring — or summer, or fall. Years ago, I grew “many-flowered jasmine” (Jasminium polyantha). A misnomer for my plant. Its fragrance was heavenly but it only coughed up a few blossoms each winter, despite my subjecting it to a period of temperatures below 60 degrees F. and some drought to give it a rest before it (was supposed to) burst  into flowering abundance.

Gardenia was another one of my plants for winter fragrance. It did bloom in winter, late winter, and its fragrance was heavenly. But it proved to be a magnet for scale insects, one of the most difficult house plant pests to control organically. Both plants have long ago been composted.

I’m now eagerly awaiting blossoms on my Meyer lemon plant. The plant is easy to bring into bloom, and there’s the added bonus of delicious lemons. Being a hybrid of lemon and sweet orange, Meyer lemon has a slightly different flavor from that of lemons.

The other plant to — reliably, I hope — blossom now, in early winter is sweet osmanthus (Osmanthus fragrans), specifically the variety Goshiki. Why Goshiki? Because it has variegated leaves, green and white with splashes of pink, spiny like those of holly. Sweet osmanthusIt’s cold-hardy to Zone 6. My plan is to grow it in a pot to bring indoors to a cool sunny window in late fall to spend the winter.

This is all a pipe dream so far because all I have is a spindly stem I cut to root from a plant beckoning me from a sidewalk near Philadelphia. The cutting doesn’t look hopeful. The quest begins.
