JOBS TO DO THIS WEEK
■ Plant summer-flowering bulbs, corms and tubers, such as lilies, cannas, ranunculus and gladioli, into pots or into the ground.
■ Prune hydrangeas, removing old flower heads and cutting back to a healthy pair of buds.
■ Place cardboard collars around brassica veg, such as cabbages and broccoli, to prevent cabbage root fly laying eggs.
■ In the greenhouse, sow seeds of courgette, marrow, pumpkin, aubergine, sweet pepper and sweetcorn.
■ Get any supporting stakes or hoops in the ground now to allow foliage to grow up and blend them into the garden.
■ If the ground feels warm, you could sow annual seeds such as nigella and larkspur.
■ Plant up hanging baskets with summer bedding, but don’t put them outside just yet.
■ Protect emerging delphiniums and hostas from slugs and snails. If you use slug pellets, consider ferric phosphate organic pellets.
