Why am I spending so much time pruning these days? To keep plants manageable and healthy, of course. But also so that flowering and fruiting trees, shrubs, and vines keep on flowering and fruiting. “Renewal pruning” is what does this.
Pruning apple spur
As plant stems age, they — like all living things — become decrepit, no longer able to perform well. But any plant’s show or productivity can be kept up if stems that are too old are periodically lopped back, which promotes growth of new, young, fecund stems. That’s all there is to renewal pruning.
Ah, but the devil is in the details. One important detail is how old is “too old.” That depends on the flowering and fruiting habit of the plant.
Near one extreme would be pear trees. Along pear stems grow stubby growths, called “spurs,” which bear the tree’s flowers and fruits.

Write the Name Right!
With little pressing, gardenwise, this time of year, why not muse about plant names — their common names and their sometimes intimidating-looking botanical names? Take the tree commonly named dawn redwood for example. ”Dawn redwood” admittedly reads more easily than this tree’s botanical name, Metasequoia glyptostroboides.
Wait! don’t stop reading! Instead, speak the Latin name aloud slowly: me-ta-see-KYOY-a GLYP-to-stro-boy-dees. It’s delightful, tonal poetry vocalized by a smooth dance of the lips, the tongue, and the upper pallete.
Sensual pleasure aside, botanical names have a practical side. That woolly-leaved plant that sends up a candelabra of creamy yellow flowers each summer has a hundred or so common names. I call it mullein but other names include Aaron’s rod, Adam’s flannel, bullock’s lungwort, and velvet plant. This plant has only one botanical name, …
I don’t let cold weather put the brakes on my composting, at least my role in it. For the bacteria, fungi, and other workers in my compost pile, it’s another story. Come cold temperatures, and their work come screeching to a halt or near halt (which depends on the degree of cold, the size of the pile, the mix of ingredients, and moisture).
But that’s no reason for me to abandon composting.
The main problem, as I see it, with composting in winter is not the workers not working. Pile up food scraps another organic materials winter, and composting will re-convene when warm weather arrives again in spring. The problem is that those food scraps offer a smorgasbord of tasty, easy calories for rodents. Which is not good.

My friend Margaret Roach (https://awaytogarden.com) is a top-notch gardener but not much of a tool maven. She recently said she considers me, and I quote, “the master of all tools and the king of compost” when she asked for my thoughts on compost shredders. (I blushed, but perhaps she was just softening me up for questioning. In fact, her tractor is better than mine.)
Of course I have thoughts about compost shredders.
Climb with me into my time machine and let’s travel back to the early 1970s, to Madison, Wisconsin, where you’ll find me working in my first garden. Like any good organic gardener, early on I appreciated the many benefits of organic materials in the garden, an appreciation bolstered by my having recently began my studies as a graduate student in soil science.
I was hauling all the organic materials I could lay hands on into my 700 square foot …
