GOURMET FERTILIZER

Vegetarian Plants
The other day in the hardware store I overheard someone ask the clerk for some rose food. My eyebrows went up as I thought to m’self, “Are they kidding, thinking that roses need their own special food? Next, I'll hear about plants that prefer vegetarian or kosher food, perhaps fish emulsion on Fridays?"
All this food science when it comes to plants may boost fertilizer sales, but it hardly bothers plants either way. Plants take up the bulk of their nutrients as ions (charged atoms or groups of atoms) that are dissolved in water in the soil. Rock particles, as well as humus…
EVOLUTION AT WORK
Green Thumb Not Needed
Anybody out there now sprinkling seeds into mini-furrows in seed flats, flowerpots, or repurposed yogurt cups? How many of us are then disappointed when, a few days later, there’s no sign of green sprouts poking up through the brown soil? Or not enough of them.
A green thumb isn’t a prerequisite for growing seedlings indoors to give plants a head start for earlier ripening of tomatoes and peppers or earlier blooms of zinnias or marigolds. Backing up every seed is 350 million years of trial and error; seeds have evolved to sprout. So why, sometimes, don’t they, and…
SHRUBS, I’M SHARPENING MY SHEARS AND LOPPERS
Shrubs are Shrubby
A shrub is a shrubby, woody plant. (Now, that’s profound.) Numerous stems originating at or near ground level are what make a plant shrubby. Usually, no one stem ever gets the upper hand over other stems. For most shrubs, you need to get out there with your pruners to snip and lop every year.
How to prune a shrub depends on when it flowers and on what age stems provide the most ornamental effect. Does the shrub flower early in the spring, or later in the summer? Does it flower on old stems, on those that grew last year, or on new shoots?
And one more thing before we…
BREWING UP BATCH OF POTTING SOIL
Prime Ingredients for Any Potting Mix
Many years, my gardening season begins on my garage floor. That’s where I mix the potting soil that will nourish seedlings for the upcoming season's garden and replace worn out soil around the roots of houseplants. Why do I make potting soil? Why does one bake bread?
There is no magic to making potting soil. When I first began gardening, I combed through book after book for direction, and ended up with a mind-boggling number of recipes. The air cleared when I realized what was needed in a potting soil, and what ingredients could fulfill these needs. A good…
TO PRUNE OR NOT TO PRUNE, THAT IS THE QUESTION
A Sharp Knife is not Enough
“Prune when the knife is sharp” goes the old saying. Wrong! (But don’t ever prune if the knife—or shears—is not sharp.) There are best times for pruning, and they depend more on the type of plant and the mode of training than on the sharpness of the knife.
As each growing season draws to a close in temperate climates, trees, shrubs, and vines lay away a certain amount of food in their above- and below-ground parts. This food keeps the plants alive through winter, when they can’t use sunlight to make food because of lack of leaves (on deciduous plants)…
GETTING TO THE ROOT OF GARDENING
Etymological Wanderings
Sure, I’ve been dropping seeds into mini-furrows in some seed flats, and prunings are starting to litter the ground outdoors. But there’s a lot of nongardening activity going on here. What better time to ponder etymology? (Etymology, not entomology, the latter of which is the study of insects; aphids, mealybugs and whiteflies, all of which will be crawling around soon enough.) What exactly do we mean when we talk about a "garden" or "gardening?"
The word "gardening" is pretty much synonymous with "horticulture," which comes from the Latin hortus meaning a garden,…
FIGS: WAIT, DON’T GROW!
Stay Asleep Please
If you garden in a cold winter climate, as do I, I hope you’re growing figs. Despite being tropical plants, figs are relatively easy for us to grow, as attested to by other gardeners, from Moscow to Montreal, Minneapolis and beyond.
If you garden in a cold winter climate, I also hope that your fig plant is NOT growing now (unless you’re in the Southern Hemisphere). The way we cold-climate fig growers help our plants face winter cold is by protecting them from it. A usual method is to grow a plant in a pot that gets moved to a sheltered location to wait out winter.…
OMINOUS HOUSEPLANTS
Poinsettia Absolved
Sunny temperature reaching the 50s a few days ago enticed me outdoors for pruning. Today, with temperatures in the 20s, I'm back indoors (except for a very pleasant cross-country ski tour earlier) looking over what plants I have, or might have, growing indoors. Their ominous or not so ominous sides.
Mention poisonous houseplants and most people immediately think of poinsettias. Actually, poinsettia's bad reputation is unfounded. The plant's not really poisonous. Only a masochist would be able to ingest enough of this foul tasting plant to cause the occasional cases of vomitting…
AN ICEY BEGINNING, WITH KIWIS
Pruning Weather
Yesterday was a fine day for pruning, windless with a sunny sky and a temperature of 19 degrees Fahrenheit. The ice storm had turned this part of the world into a crystal palace, with branches clothed in thick, clear sleeves of ice. From an auspicious vantage point, a pear tree glowed like a subdued holiday tree as hints of sunlight’s reds and blues refracted from the natural prisms on the branches.
What a pleasant setting for pruning! The usual recommendation is to hold off pruning until after the coldest part of winter, which typically occurs in late January and early…
