I'm a bit of a novice at gardening... but it was a really nice day today and I was stuck indoors all morning. Got outdoors after lunch, started weeding in the shared garden at the back. I must have pulled up ten buckets of ground elder and I shoved it all in my compost bin (roots and all). I've since noticed warnings against this, , not sure why and I'm now wondering if I need to remove it from my compost bin? Anyone know?
