It always sticks in my mind that I was told by an old gardener years ago, not to put rhubarb leaves into the composter. What other plants / foliage should I avoid putting into the compost?

Thank you all for your replies.

Rhubarb leaves are fine in the compost we bung ours in every year... I wouldn't put seeds of perennial weeds in as our compost does not get hot enough to kill them off, neither would I put in potato and tomato foliage that has been blighted. Any particularly woody growth, such as Brussels sprout stalks needs to be given a good thumping before going in the compost or it will take forever to breakdown. Too many grass clippings aren't good either, balance is everything as always.

It maybe that your old gardener knew that rhubarb leaves were poisonous and so assumed they shouldn't be composted - but that's only if you eat them, there's no problem at all with composting them.

Everything (that is garden waste) goes onto my heaps except couch grass and diseased foliage and I have had not trouble.

Thank you all for your replies to my composting question, I have put everything through the shredder (even the sweetcorn straw) and its all gone into the composter.
