Weekend Work: Time to increase stocks of hybrid berries

What to do

Increase stocks of hybrid berries such as loganberry and tayberry by tip layering. Bury the tip of a shoot about 15cm (6in) down in the soil and firm the earth round it. By spring it should be rooted.

Pick and prune late-fruiting blackcurrants in one fell swoop by cutting back all the stems carrying berries to a strong new shoot. On old bushes or those which do not have much non-fruiting growth, cut out about a third of the branches entirely.

Cut back helianthemums. Delphiniums may give a second show if you cut down the old stems.

Take cuttings of Camellia japonica, using half-ripened side shoots. Root the cuttings in pots of sandy soil.

Propagate lavender now, too. Choose 8-10cm (3-4in) lengths of non-flowering shoots and stick them in a pot or a shady cold frame in sandy compost. Keep them well watered. Rooted plants can be set out in spring.

What to see

More than 1,500 knitters contributed to 'Blooming Marvellous', a knitted garden on show at the Bridport Arts Centre, South St, Bridport, Dorset, until the end of August. Look for knitted slugs and snails, apples, butterflies, even a barbecue. On Bank Holiday Monday (from 12-2pm) you can join the Knit-a-Thon in the Arts Centre forecourt.
