I moved to my present location 7 years ago. My burgeoning orchard had been corned for years. That, on a “mineral” soil type left the field, shall we say, deficient for most living things. Knapweed took over.
Multiple years of light discing of cover crops did some damage to the scourge, but it’s still there.
My current regimen of wood-chipping near trees and cover cropping/incorporating the alleyways seems to be improving the soil, but the Knapweed persists. I’m beginning a regimen of light wood-chipping the alleyways/incorporation with light discing.
My question, as Knapweed is known to thrive in substandard soil when/where other plants can’t survive, I am wondering if eventually, with improved soil fertility, other plants will be able to squeeze it out. My backup question… should I even care in a cider orchard? It seems that eventually the trees will live above the scourge.
