I TAKE A CLOSER LOOK, AND LIKE WHAT I SEE
Hey Bud, ‘Sup?
Nothing like winter to force me to take a closer look at my trees and shrubs. “To see what, you may ask?” To look at their buds, within which lie the makings of this season’s flowers and shoots. Not only are the buds quite distinctive, but they also offer a crystal ball into the future, which is very important to me as a fruit grower.
Trees’ and shrubs’ fruit and shoot buds look different from each other. It’s the fatter ones that open to become flowers and then, barring damage from late frosts, insects, diseases, or hail, fruits.
Last year, perhaps because of dry weather or a late spring freeze, my pawpaw crop was a failure. This explains why I now see so many distinctive plush, velvety, fat, brown buds — flower buds — lining the stems. For any fruiting plant, a light crop of fruit one year generally makes for a bumper crop the following year.
My cornelian cherry tree also prognosticates a bumper crop, even more obviously, because its flower buds stand prominently proud of the stems like buttons on the ends of short stalks.
On peach trees, flower buds develop only on one-year-old stems. The flower buds aren’t that distinctive except for being fat. The buds at some nodes, the junction where leaves met stems last summer, come in triplets, one single, small shoot bud wedged practically into hiding between two big, fat flower buds. The buds tell of a good crop of, at least, flowers.
Apple buds are different still. Their flower buds are mostly on spurs, which are short, stubby growths that elongate only a half and inch or so each season. Not all buds on these spurs will open to flowers, though. Some — again, those that are less fat — will open to shoots that will grow only a fraction of an inch longer and then flower the following year.
Pear buds are very similar to apple buds, the main difference being that I find it harder to differentiate, especially now, between their shoot from flower buds. As spring inches closer, these and other buds will all begin to swell to let their plans be better known.
A Bud Is Like A Crystal Ball
All this staring at buds is not just for winter entertainment. It also guides me in pruning.
To ripen a fruit demands a lot of a plant’s energy. If a tree or shrub bears too many fruits, it will, once danger from frosts and many other hazards are behind it, naturally shed some of the excess. But what’s left might still be more than it could ripen to perfect size and flavor for us humans.
One reason I’m stomping around among my trees and shrubs outside is to prune them, and one of many reasons that I prune them is to remove some of the fruits before they even begin to form. Cutting back some stems cuts off some flower buds, which makes for less fruits.
With all their fat flower buds, my pawpaw trees will get a severe pruning. The same for my peach tree, but not quite so severe. I’ll wait on the apples and pears until it becomes more evident what’s what.
Not that my sole purpose in pruning is to cut back fruit production. Some kinds of pruning cuts also are meant to stimulate vigorous shoot growth to reinvigorate a plant or provide flower buds for the following year. I’ll also prune to let branches bathe in light and air, keeping photosynthesis chugging along this summer and limiting pest problems. My cuts will also be directed towards maintaining strong limbs able to support a good crop. (Interested in more about pruning? See my book, THE PRUNING BOOK.)
Nice Bark, Woof, Woof
Looking at buds isn’t the only winter entertainment provided by my plants. How about checking out their bark?
Among the trees and shrubs I’ve planted, my three favorites barks are those of hackberry, river birch, and stewartia. Hackberry has a gray bark with ridges on it that, when struck by low winter sun, have a distinct, achromatic light and shadows that remind me of photos of the lunar landscape. My tree still have some years to grow before their bark is notable; for now, I enjoy looking at he bark on some wild plants I know.
River birch bark has a cinnamon-colored bark that naturally curls and peels off up and down the trunk to create a colorful mix of creamy white, pink, and brown colors.
My Japanese stewartia has the bark that would stop traffic, if there was traffic here. This bark is mottled with dark brown, light brown, and silvery patches. In a few months, leaves will mostly hide the bark, but then white blossoms that look much like camellias will continue the show.
