Get some 'Pallet collars', make as many little raised beds as you have room for (3 makes a hand height) and grow stuff you enjoy eating. In this year's lock-down, we've now got loads of onions, potatoes, lettuce, garlic and even broccoli. Much of the compost was free courtesy of the moles!! It's been limited effort and very rewarding - not to mention tasty and money-saving.
