I used to prune in the absolute dead of winter. The trees were fully dormant and the pruning wounds would dry and heal over before spring’s sap run. But I read an article about “killing frosts” in the spring. Not that they killed the trees, but that the frost either killed the blossoms, or the trees would bloom when it was still too cold for the bees to pollinate.

This is a very real issue with our new climate uncertainties. Not that all of the elements of seasons aren’t present, but that they might not occur ‘in concert.’ Over the millennia, plants and animals everywhere have developed an elegant and intricate dance, specific to region. The robins arrive just as the snow departs. The swallows of Capistrano arrive just in time for the hatching of their insect dinners. But what happens, if the storks arrive and dinner is not on the table? I saw an internet post celebrating the arrival of our first robins here, but when I look out the window, there’s still at least a foot of snow on the ground. Where will those early arrivers get their worms?

Every species has its own internal clock. Some are triggered by temperature. Some are triggered by the angle of the sun. None, so far as I know, are set in motion by the Weather Channel’s debates over the American or European Model of prognostication. Here, in Leelanau, we are only beginning to learn the fancy steps to our dance–just as the local farmers and gardeners are scratching their heads about changes.

According to the pruning article, one way to protect against killing frosts is to prune a little later–when still dormant, but closer to when the sap begins to run. When the tree is pruned, it takes some time for it to adjust and re-assign the hormonal signals in the branch’s ‘lead buds.’ Timed right, this will give you a slight delay in budding, thus reducing the risk of crop losses due to frost. It may also put your fruit at more risk from insects…but you have to weigh the risk of no crop or one that requires defending.

I have ordered new pruning shears. Many years ago, I owned a fine set of Felco pruners, but that was a lifetime ago. In the meantime I’ve made do with a cheapie set, from the local hardware. They were hard on my hands, and hard on the trees. Though our trees are still small, our orchards are expanding. It’s time.

It coincided with the loss of the crappy pruners. I’ve looked everywhere, to no avail. So I’ve ordered a replacement pair of Felco’s and as soon as they arrive, I’ll get busy with the pruning. Yesterday felt like spring, but today it’s snowing again. I’m sure that I’m still within a reasonable dormant pruning window.

I have always loved pruning. It makes me a part of that intricately timed dance. Orchard trees are bred for care and do better when pruned and managed. This chore is a reminder that even when the plant world is asleep under its blanket of snow, its clock is ticking. Spring is coming. There’s work to be done.
