You can never have too many bins.
Planters & pots, temp or perm
Handy carry-alls for e.g. water, eggs, seedlings from neighbours, spare shoes, firewood, tools, mixing things for sprinkling on the plot, harvesting, weeding, lunch ;D
Liquid fertiliser makers (see threads on sheep poo and comfrey tea!)
Upside down for blanching rhubub, endive, chicory, seakale
Point out to OH that rhubub blanching pots cost about £50, think of all the money you're saving with your thrifty ways ;)
