How do you control weed growth through your carpet paths?
Admittedly, I can be a somewhat messy and inattentive weeder, but the one year I tried this ...dirt with bits of roots fell on the carpet and grew through it. Birds and breezes also dropped weed seeds which sprouted through it. Trying to remove wet, dirty, smelly carpet that's tacked to the ground with roots is amazingly difficult and messy...and then what do you do with it? It's heavy!
I guess if a weed killer were used in conjunction with the carpeting it might not have to be moved for years, but without adding additional chemicals to the mix, it can, in some instances, be very difficult to deal with.
I'm content using biodegradable plant matter for my beds, but I'm still curious as to your weed control methods.
