When you pull out mounds of invasive weeds from your backyard garden, what do you do with them? You can compost them, but when you spread the compost, will you also spread weed seeds? The greenest solution is to bag them in black plastic trash bags and THEN compost them. Placing the weeds in a black bag and allowing them to bake in the sun is a simple way to kill the seeds by scorching them, called "solarizing." After a few days, simply empty the bag into the compost, and you’re good to go.
