Don't think I've emptied my kitchen compost bin for a couple of weeks. I went to do so just now - opened the garden compost bin lid to find enormous bean sprout plants staring me in the face growing from the compost - looks creepy! Obviously bean sprouts are a no-no for composts! Can I do anything about it or do I have to throw all the compost away now - there's masses of it - almost 3/4 of a large bin full.
