What shouldn't go in your compost bin?

Stuff like ground elder I would drown or solarise instead, but our green bin collection is free so it goes in there for the professional composters to take care of.

I think I will continue to let them
take care of it but get the Johanna as well  
Digging up ground elder is such hard work, and really upsetting to see it invading new areas of ground it's worth £40 to take it off site. I can't chance it! I don't know how long it has to sit in water before it will sprout again?

I often have a few buckets around with weed sitting in water.

I would love for it by to disappear overnight, it is so much work to keep on top of it. It's in the grass...so it creeps in the borders.

My neighbour moved here about 5 years before me. She weed killed the whole garden and dug every root before starting again. I wish I had known how difficult it was.
