Don't chuck away your empty plastic food packaging at this time of year - get yourself a sharp pair of scissors and recycle them as plant labels. Best recycling tip I ever got! Any white plastic will do, though I find the thickness of margarine pots particularly suitable. Even milk containers can be pressed into service.
Make sure you use a good permanent marker though, or you'll have mystifying blank strips of plastic 3 months from now...
Saves me a fortune in plastic labels, so thought I would share.
