from the forum: can i compost weeds?

FORUM MEMBER TERRYK IS SO RIGHT TO ASK: Whether or not we can add weeds to our compost heaps without risking weed-filled finished compost is a confusing topic. Won’t all their seeds sprout, or runners survive–especially in a slow-cook, not-so-hot heap? This week, we have the answer in the Urgent Garden Question Forum…thanks to some advice from our English gardening brethren (and a couple of giant plastic bags). Find out how it all works right here.

    I’ve been busy back at wok but thanks for the info. The bagging method sounds great! I’ll put it facing a south wall and cook them to death for sure!

    If I didn’t compost weeds, I would have very little compost. My “method” is to just pile it all up and let it sit. Weed seeds are not killed so I have to smother the compost with mulch when I use it, but I have never had a problem with Canada thistle growing from the compost, so it must rot well.
