Fall Care of Perennials

There’s been some aggressive weeding of late. I found the tell-tale sign the other evening: come the end of the day, I went about my dutiful effort of hair brushing only to have the exercise yield a brush full of twigs and accompanying detritus. 

Mind you, projects for the week have focused on “perennial triage.” That is to say, freeing trees and shrubs from encroaching weeds, invading vines and the ever-dominant wild raspberry. Thorns, thickets, prickers and spines require a careful approach, while bedstraw, vetch, grasses, wild strawberry and rogue ferns necessitate an all-or-nothing tenacity. Somehow the dirt dirties more than just my hands. 

The goal is multifarious. These perennial plantings are easily pushed down the priority list throughout the growing season, so taking the time to clear around them now, as the season winds to a close, is essential if they are to be given a stronger start come springtime. After weeding around each tree, a mulch or sheet mulch is applied for fertility and weed suppression.   

Our sheet mulching method here at D Acres incorporates two primary materials. First is cardboard collected from area establishments, a means of up-cycling biodegradable material otherwise destined for a landfill. Second is a woody byproduct. Often woodchips are used, a resource we have readily available from our logging efforts. At the moment, I am making use of sawdust donated by a neighbor. Piled in a less than ideal spot, my goal has been to work through the material as quickly as possible. Another week of sheet mulching should easily accomplish the task. Of these two materials, cardboard is utilized for weed suppression, while the placement of organic matter serves to hold the cardboard in place while simultaneously providing a rich nutrient package that will slowly be released and returned to the soil.
