Can weeds be composted? How can they be prevented from germinating in the compost?
Weeds that have not gone to seed can be composted. Those that have gone to seed can survive temperatures up to 60oC, which even a very hot heap of household compost will not reach in a uniform way. Hard-to-kill weeds like couch-grass, golden grass, flowering ragweed, and poison ivy should not be put into a compost heap even if shredded.
