Blueberries & Cicadas, Mmmmm

“It takes a patient man to net an acre of blueberries.” The New England accent added weight to the declaration, as did the gentleman’s 80-something year old frame standing ramrod-straight and adorned with checkered jacket, a cap, and chinstrap beard. That was 30 years ago, and I was standing in the New Hampshire garden of Elwyn Meader, looking across the field at his acre of blueberries. Elwyn was a plant

breeder extraordinaire, then retired, who had developed new varieties of such plants as persimmons, chestnuts, lilacs, cucumbers, soybeans, watermelons, and everbearing strawberries. The honey-sweet Fallgold raspberry, my favorite, was Elwyn’s handiwork, incorporating genes from Korean raspberries he found while working there for the U. S. Army. 

Now, many years later, I think of Elwyn’s words as Deb and I rush to net our small plot, two-hundredths of an acre, of blueberries. (Not so small, though, to obviate a very respectable harvest of about 190 quarts of delectable, organic, sustainable, artisanal berries from 16 plants!) I append Elwyn’s words with “Covering two-hundredths of an acre of blueberries is a test of a marriage.” Nets can sag; tempers can thin; ladders can become unwieldy.
We survived. My latest incarnation of blueberry protection against birds starts with an enclosure of locust posts about 8 feet apart, with rebar running through holes a few inches from their tops. The sides, as my friend Bill calls it, my “Blueberry Temple,” are enclosed permanently in heavy duty, plastic bird netting (www.bennersgardens.com). Eighteen-inch-high chicken wire at the bottom keeps rabbits from chewing through the plastic. 
Now for the seasonal net, the one that tests our marriage and covers the planting while berries are

ripening, from late June until September. This net is of woven nylon, so is sturdy and drapes well (available from such sources as www.raintreenursery.com, www.jacissel.net, www.nylonnet.com). We spread the rolled up net on the ground near the entrance to the planting, then, each of us climbing a ladder at either side, lifts the roll up across the top, with either end of the roll resting on opposite sides of the rebar. Letting the free end drape a little over the entrance side, we each use a binder clip to fix the beginning of the roll near the entrance side. From then on, it’s a matter of unrolling the netting over the top, clipping and moving ladders as we go and — this is the part

that can get testy — making sure to keep the net even on both sides and sufficiently taught.

This year, the net was up in less than a half-hour, the blueberries were safe from birds, and the marriage was still intact.

Pruning tomatoes is such a pleasant garden “chore.” As I look over each plant for suckers — any shoot that originates at the upper part of juncture between a leaf and main stem — I get to monitor the swelling fruits, do a health check on the leaves and stems, and admire the plants’ neat growth habit. The latter comes from my weekly pruning off of the suckers followed by tying of the main stems to adjacent bamboo poles.
I can appreciate disorder in the garden but I also appreciate order. Disorder lends a pleasant, loosey-goosey atmosphere to the landscape. I find order more calming and an easier environment in which to satisfy the needs of each plant. For the tomatoes, pruning and staking them — which surely puts them in order — also gives greater yields (per square foot of garden space), and fruits that are cleaner and a bit earlier.
All this orderliness crumbles as August fades into September. By then, errant suckers get the best of me and the ever-elongating main stems reach the tops of their bamboo supports. Then where can they go? Sideways? Down? To an adjacent pole? No matter. By then, the end of tomato season is in sight and the plants pretty much do what they will as long as they keep pumping out juicy, red orbs.
——————————————
The novelty of cicadas has worn thin. Their electronic cacophony whines in various pitches throughout the day without a moment’s respite. If you saw me walking past any one of my many infested trees or shrubs, you might see my arms flailing about to keep airborne ones at bay.
Thankfully, cicadas aren’t feeding on any plants. But their egg laying, beneath slits they make in bark, can cause damage. Young stems dying back do little damage to established trees and shrubs (gratuitous summer pruning of shoots?), but can kill young plants.
Here, the cicadas favor the lilac bush and pear trees and, to a lesser extent, the apple trees. I’ve gotten pretty good at snatching them by their wings. My chickens are very fond of the fresh, less so the frozen, catch of the day. This hand to hand combat feels good but makes but a small dent in the population.
The other afternoon I could no longer stand the sight of so many cicadas clustered on the trunks of my 8-year-old pear trees. I needed a bulk method, so ran indoors to grab a dust broom. The dust broom was quite effective, sending cicadas flying everywhere. And then back onto the trunks.
My last resort was to get out my sprayer and coat the trees and any resident cicadas with ‘Surround’, a commercially available,

organically approved pesticide made from kaolin clay. The coating makes for unpleasant footing and egg-laying for a variety of insects, and it clogs their spiracles.

The ‘Surround’, which I applied only to the apples and pears, had but little effect on the cicadas. Cicadas on plants became statuesque; a few fewer flew back on, for awhile. Of course, the incessant cacophony emanating from the woods continued. Only a couple of weeks or so to go, and then a 17 year hiatus.

Pruning, Not Too Late

Nicole, from near Madison, WI won the grow GROW FRUIT NATURALLY book giveaway. Congratulations Nicole! Contact me through my website, www.leereich.com with your mailiing address so I can get the book out to you.
——————————-

Time is running out to finish pruning my kiwi and grape vines, apple, pear, cornelian cherry, filbert, and chestnut trees, rose, gooseberry, currant, blueberry, raspberry, blackberry, yew, and fothergilla bushes . . . now that I list most of them, it doesn’t really seem like too, too much still to prune. Some people worry that it’s too late to prune. Nope. Most pruning is done during the dormant season, that is, anytime plants are not growing or, if deciduous, leafless. (A notable exception is spring-blooming shrubs, which are best pruned right AFTER they finish flowering. For more on all aspects of pruning, see my book, THE PRUNING BOOK.)
Kiwi, before pruning
I’ll usually do a little pruning in autumn, after leaves fall, but mostly I’ll be grabbing pruning shears, loppers, and saw as I go out the back door in late February or March, after the coldest part of winter is over. Waiting is most important with plants that are least cold-hardy because these plants tolerate cold better if left alone and, by waiting, I can see what has been damaged during winter. Buds on damaged stems aren’t swelling up this time of year so those stems can be cut off.

A few plants warrant dragging out that waiting period even longer, until they are in bloom, which is when they heal quickest. Peaches are prone to infections at wounds, pruning or otherwise, making these trees good candidates for waiting.

Kiwi, after pruning

———————————–
I may also wait to prune my grape vines until new shoot growth is underway because then they are less likely to bleed sap.
Bleeding sap worries many gardeners. Isn’t the plant suffering from that gaping wound oozing a watery fluid? No, bleeding does no harm to grape vines. But some of my grapevines climb along the arbor over my patio. It’s very pleasant to sit outdoors on that patio on warm, spring days; it’s very unpleasant to sit there with sap dripping on my head.
Kiwi vines also bleed. No matter. My kiwi vines climb a strictly functional trellis below which we don’t sit.
Root pressure of water being forced up the vines is what makes grape and kiwi vines bleed. Once leaves unfold, they take up that pressure and bleeding ceases.
———————————
Bleeding is most welcome from maple trees. What comes out this time of year is a dilute, sugary sap that, when boiled down to concentrate the sugars, yields maple syrup and, if boiled down still more, maple sugar. Sugar concentration in the sap can vary, depending on such factors as temperatures, age of tree, site, soil fertility, and moisture. Typically, the ratio of sap to finished syrup is 40 to 1.
It’s not root pressure that’s forcing sap out the spiles I’ve tapped into holes bored into two sugar maples. Maple sap runs best when temperatures fluctuate between 20-something degree nights and 40-something degree days. Cooling temperatures cause gas bubbles in the trees xylem cells (the inner ring of trees’ cells in which liquid is conducted upwards from the roots) to shrink and to dissolve. Something’s got to fill that newfound space, so more liquid is sucked up from the roots and into the cells. As temperatures drop further, ice forms and gases are locked within the developing ice.

Come morning, pressure builds in the cells as rising temperatures melt the ice and release the gases, forcing liquid out any holes in the bark. That liquid makes its way out the spiles, thence to buckets hanging beneath the stiles, and finally to a large pot that sits and steams on my woodstove through February and March. When the sap reaches 67% sugar, boils at 219° F., or tastes like maple syrup, it’s ready to be bottled up. For me, this has been a good year, with over 5 quarts of syrup already from only 4 taps.
Only a few trees can be tapped for their sap. Any maple can, as can black walnut and butternut. Each yields a syrup with a different flavor. Birch trees also release a sap that can be boiled down to make a tasty syrup; in this case, though, it is root pressure, as with grapes, that forces out the sap.

A Jump on Spring

I got a jump on spring yesterday and started pruning hardy kiwifruit vines. The fruit is a kissing cousin of fuzzy, market kiwis, except, with smooth skins and small size, they can be popped whole in your mouth like grapes. Hardy kiwis are also cold-hardy, which their cousins are not.
The vines need yearly pruning to let light and air in among the stems for productivity and plant health, to keep fruiting stems within easy reach, and to stimulate new stem growth each year off which grow fruiting shoots the following year.
My plants are trained on 5 wires strung between T-trellises, one wire down the middle of the trellis flanked by 2 wires on either side of that central wire. Each plant’s trunk rises up to the middle wire and then divides into two cordons, or permanent arms, that run in opposite directions along the middle wire. Fruiting arms, which are 1-year-old stems, grow off perpendicularly to the cordon to drape down over the outside wires.
As I approached the vines with shears, lopper, and small saw in hand, the vines looked back at me like an intimidating, tangled mess. Three steps in pruning brought everything in order. I first cut back all fruiting arms to within a foot or so of the outside wire and shortened each cordon back to where it began growth last year. Arms bear fruiting shoots near their bases so don’t need the whole of their lanky stems. As to the cordons, if they were allowed to grow longer and longer, one plant would tangle into the next plant down the row.
Next, the hardest part: I reached into the remaining tangle to cut back fruiting arms that have, over the years, begun to originate further and further off the cordons. These got shortened so that new shoots, for fruit 2 years hence, would originate closer in to the cordons. Left to their own devices, as they are in the wild on the edges of Asian forests, the vines would be climbing 100 ft. high on anything on which they could grab hold.
Finally, I thinned out most of the remaining fruiting arms so that they are about a foot apart. I’ll do a final pruning in spring, thinning more where needed and shortening all fruiting arms to their final length of about 18 inches long.
I’m left now with a pile of prunings. Their intertwining stems make nice decoration. I could also save some for my cat. Kiwi stems have a pleasing effect on the cats, similar to catnip. In Asian zoos, they have been used to calm “large cats.”
————————————————-
What joy a mere sprout can foreshadow! Late last summer a gardening friend gave me some sprouts from her Maid of Orléans jasmine (Jasminum sambac). By the end of summer, a few of the cuttings had rooted and even flowered.  The plant or its flower wouldn’t win (or lose) any beauty contests, but is well worth growing for its unabashed fragrance. The aroma is sweet and rich and not at all cloying, even after the flowers fade.
What’s more, this jasmine flowers freely. As a matter of fact, it just finished its second round of flowering. Contrast this behavior with my two plants of common jasmine (Jasminium officinale). These latter plants occasionally cough forth a few flowers in late winter but nothing like the profusion of white blossoms they once did. I’ve tried everything, from starting new plants from cuttings to pinching shoots all summer until August to keeping them cool in until late winter to keeping them dryish until late winter to keeping them cool and dryish until late winter to keeping them in the greenhouse to . . .  you get the picture.
The only dark cloud hovering over my Maid of Orleans was the potting mix. Something seemed not quite right with it, having me worried that the plant might not grow or, worse, expire (as did the plant from the gardening friend from whom I got the cuttings). Not that this is a time of year to expect growth from any plant.
But now, that cloud has moved on. The new sprout looks happy and healthy and foretells of a fragrant future.
————————————————-
I mixed up a new batch of potting soil, which I’ll need anyway in a couple of months for indoor sowing of the first seeds of next season. Into a 5 gallon bucket went finished compost and soil, equal parts, sifted. Into another 5 gallon bucket went peat moss and perlite, equal parts, sifted. I tipped the contents of both buckets together into the garden cart, sprinkled on 1 cup of soybean meal and a handful of kelp, and repeatedly slid a flat-bladed shovel under the pile and turned it over and over. Once everything was thoroughly mixed, I shook and forced it again through the 1/2-inch sieve and packed it away into buckets.
This potting mix will be home to the roots of seedlings and houseplants, as well as large, potted fig trees, roses, and pomegranates. Also, to Maid of Orleans, as soon as she outgrows her present quarters.

PRUNING, I CAN’T RESIST

Now is generally not a good time for pruning outdoor plants. Too bad. With the lawn nicely trimmed and vegetable and flower beds tidied up, it’s all the more difficult to resist the urge to lop back at least some misplaced or congested stems on trees, shrubs, and vines.
Redosier dogwood, neglected
I can’t resist. I figure little or no harm should come as long as I choose carefully what to cut. One reason not to prune now is that any wounding — and pruning does wound — stimulates a certain amount of cellular activity near the cut at a time when plants should be hunkering down for winter. Resulting cold injury can be minimized or nonexistent if pruning is restricted to the most cold-hardy plants. Also, gaping wounds won’t heal until spring so are open to pests. Here I rationalize that problems will be, again, minimal or nonexistent if only naturally tough plants are pruned now.
I’ve been eyeing an ungainly redosier dogwood since leaves have dropped. Redosiers are super-hardy, shrubby plants that liven up the winter scene with their bright red or yellow stems. The time to prune these plants is in early spring, after enjoying the plant’s colorful stems all winter.
The problem is that my redosier dogwood has been neglected for years. Only the one-year old stems are colorful and, with years of neglect, few are evident amongst the older wood. The right way to prune this plant is to lop the whole shebang to the ground every year or two in spring. Doing so coaxes a slew of vigorous, new sprouts near or just below ground level. Come autumn, these sprouts are officially one-year old (that is, they’ve completed a whole season of growth) and need only crisp weather to bring out their brightest color.
I’m lopping my whole plant to the ground this week (in addition to the boxelder and other weedy plants that have sprouted up among it). The plant is very hardy, has nothing to show for winter, and pruning now leaves one less thing to do in spring.
Black & red currants, pruned
Likewise very cold-hardy and likewise soon to feel the steel of my pruning shears are my currant and gooseberry plants. Gooseberries and red currants bear fruit on one-, two-, and three-year-old stems so I’ll be cutting down any stems older than three-years-old and thinning out the youngest stems so that they don’t crowd as they age. Black currants fruit best on one-year-old stems so I’ll cut down any stems that bore fruit this past summer and thin out young stems if they crowd too much. All these plants start growth very early in spring, which is one more reason to prune them now.
————————————————
Redosier dogwood, pruned & very red
Stems don’t speak to me or bear age labels, so how do I know which ones are one- or two-years-old, or older? I look at them. With some plants, it’s very easy to tell. As I wrote, only the very youngest redosier dogwood stems turn red or yellow, with the help of cold weather. Kerria, also known as Japanese rose, blooms best on one-year-old wood, which broadcasts its age with its bright, green color; older stems are brown.
Other plants’ stems offer hints of their age even if they don’t colorfully broadcast it. Oldest stems generally are those that are the thickest. Stems also show their age in bark that starts to peel or gets bumpy or warty; that is, it looks old.
————————————————-
I’m not yet finished cutting. Lanky stems lash out and grab me as I pass across my terrace beneath the grape arbor, or walk down the field near the trellised kiwi vines. I’d like to prune them now, and I will, to some degree at least.
Kiwi expert Dave Jackson, who grows some of the best hardy kiwifruits I’ve ever tasted (www.kiwiberry.com), has 20 acres of the plants. He tells me that he prunes in autumn with no ill effect, so I’m tempted to do so also. Kiwis require more pruning that most plants and one reason he prunes in autumn could be because he wouldn’t have time to prune everything if he waited until spring.
Temperatures and airflow here at my farmden are not nearly as congenial for the plants as at Dave’s farm, which makes me wary of pruning my vines now. So I’ll prune a couple of my kiwi vines now and see how they fare. The rest will get pruned in spring. 

But I’m going to shorten lanky stems on all the kiwi plants, as well as those on my grapes. Plants pack away food for winter in stems, so cutting stems does remove some winter stores; still, many stems, trunks, and roots will be left intact. Right near pruning cuts is where plants are most susceptible to damage. Shortening stems partially, rather than to their full length, avoids  problems near the cuts. Final cuts can wait until spring.
————————————————-
Some plants needn’t feel even slightly threatened by my pruning shears — now, at least. Pruning butterfly bush in autumn, in my experience and that of many other gardeners, results in increased winter cold injury. Come spring, though, all their stems get lopped to the ground. I also won’t touch spring bloomers, such as lilac, forsythia, and mockorange bushes. Pruning would remove stems slated to bloom this spring. The time to prune these plants is right after they finish their flowery shows.
