What should you be doing in the garden this weekend?
Roses: spray against fungal diseases and pests, and feed generously. Plant new ones, ensuring side dressings of compost and mulch. Prune spring flowering shrubs after flowering. Deadhead rhododendrons.
Feed acid loving plants (eg, camellias, azaleas etc) after flowering. Sow seeds of flowering annuals directly into the ground: alyssum, californian poppy, statice, marigolds, cosmos, nasturtium and sunflowers. Sow in trays for transplanting later: carnations, dahlia, livingstone daisy, petunia, salvia and gerberas. Plant out seedlings of flowering annuals. Plant perennial and summer flowering bulbs such as dahlia, begonia, gladioli and calla lily. Plant hanging baskets and terracotta pots with flowers for summer colour.
Mulch all plants to conserve moisture and check your watering systems. Liquid feed all flowering annuals and perennials. Feed flowering shrubs. Turn compost heaps and dig in organic matter. Keep roots cool by mulching. This will also help control weed growth, retain water in the soil and enhance its structure.
Get planting new season herbs, including coriander, oregano, rosemary, basil, tarragon, caraway, dill, thyme and parsley. Find a warm spot in the garden, but watch out for late frosts.
