In the garden this week: Quick crops and houseplant treats

Quick crops Make the most of limited vegetable growing space with a bit of sneaky intercropping. Some crops are in the ground for a long time: sweetcorn, brussels sprouts, sprouting broccoli and tomatoes all need nothing more than time (and water and sunlight) to build up for the big crop. Plant quick and lively types to snap around their heels. Lettuce, radish and spinach can be in and out before the big, slow plants have even started producing. Pamper houseplants It's a little early to put houseplants outside for a summer freshener – it is still cold at night and we must watch for a late frost – but you can start them into vigorous growth by cleaning and potting them up. Wash off winter dust coats with a soft cloth and warm water (or hold the tops under a lukewarm shower), then transfer into a slightly larger pot with fresh compost, top-dressing as you go. Water and feed for a satisfying flush of new growth.
