While spring, summer, and early autumn call for prettily tidied ornamental gardens, now’s the time to let them be. As the caption says, rake the paths if you wish, but if you’re lucky enough to have leaf-fall in the landscape, leave them lie.
Oddly enough, I was pursuing this line of thought when I received my Defenders of Wildlife leaflet that pointed out the efficacy of leaving leaves (lots of rhyming possibilities here) lie over the winter. Their “Living Lightly” column indicated that leaf cover enhances biodiversity in many ways — providing soil protection during hard freezes (already here); root cover for shrubbery, and most of all, a comforting blanket and nourishment for myriad beneficial insects, hibernating toads, salamanders, garden snakes and even bumblebees.
The habit of raking it all up and bagging for the city to pick up should include only path, patio and driveway leaves — for lawn leaf-cover is also beneficial for the microbes, millipedes, crickets, worms, spiders and more that keep them healthy by suppressing weeds and fertilizing the soil.
Leaves are the perfect natural mulch, so leave them till spring thaw, then lift carefully upon removal, for you may, as I have, be delighted by the rare sight of a tiny human-handed salamander or small toad. My annual spring ladybug breakthrough comes from under the leaf-cover for my wild rose roots and stems — always a thrill.
By the way, the article came down hard on leaf-blowers, and I am in agreement with that. My former neighbor had one so powerful its piercing scream entered my head through the walls of my house. It was terrible — they are not a friendly implement and DFW pointed out that they are an environmental hazard “with a two-stroke engine that fails to undergo complete combustion, which means that they produce nearly 299 times the air pollution of a truck.” If you feel you must use one, says DFW, make it electric.
Last year at this time, I provided excerpts from a variety of sources for a final fall/winter “to do” list for Zones 3-4-5 — which encompasses our areas’ growing seasons. Here’s a repeat of a few of them.
* Avoid deep cultivation around shallow rooted trees and shrubs such as evergreens. Roots can freeze or crack during freezes. A little mulch of straw (better than hay, since nothing eats it) or leaves can protect until snow comes to do the job.
* Leave faded flowers on those plants that form ornamental seed heads, pods or berries (rose-hips).
* Use cold weather “downtime” to sharpen mower blades, shovel edges, hoes and such to prevent leaf blade damage and lawn stress next season.
* Gather up empty pots for storage. Scrape out any residue, scrub with a sponge or old towel if necessary, and for safety’s sake, clean in a diluted bleach solution (1 part bleach to 10 parts water) and air dry.
* If you haven’t already, mulch perennials planted in large garden pots with an armful of leaves or straw; wrap the pots with burlap or other protective material. An effective solution is to create a column inside the pot with chicken wire; cut it twice as tall as the plant then dump it full of leaves. Add a cover if you wish or pinch the top together.
* Wrap the small trunks of young trees from base to first branches with hardware cloth (old Ace bandages are great.) This keeps the deer and rodents from nibbling the tender bark.
* Continue to turn the compost pile frequently, while enhancing it with potato peels, coffee grounds and eggshells for enriching gardens for next season’s planting, right up till snowfall. Then, cover the pile with a tarp or canvas, weighted down for winter’s winds and let it work and “cook” till spring.
* If you burn wood (real wood, not commercially made logs) save the ashes for use in the spring as a soil amendment of potash and/or lime where needed. A small amount may be used in the compost pile, but incorporate it well.
OK. We’ve all done what we can to ensure a safe, environmentally sound situation in the landscape. Time to put on the fuzzy slippers, make a cup of hot cocoa and sit by the window with the binoculars enjoying the birds at your feeders.
