Can i put these into the compost bin?

[mumofstig]

The annual ones can go in but I don't put the perennial ones in, cos they can regrow.

but if you have a spare container, you can drown them for a couple of weeks in water, then put them on.

I had a spare 1tonne bag, so last year I put all my nettles etc in there, and nearly everything has rotted down to almost nothing.

Excellent I will drown them then.

alternatively, in this weather, lay them out to crisp up on fabric or mesh. weeds with big roots like dock or dandelion might still survive though...
