It's time to: June

Prune

Prune dead foliage on dahlias to the ground. Use a small stake to mark the site of the dahlia and its name. Spread a layer of cow manure around. Dahlias will re-shoot in late spring.

Protect 

Protect budding magnolias against possum damage with a sonic device such as Strayban.

Plant

Plant a shade tree for future pleasure and protection.

Plant tulips in the garden and in pots.

Old roses flower well in winter and it’s a great time to plant them. ‘Marechal Niel’ is a climbing tea-noisette with soft-yellow, scented blooms. ‘Safrano’ is an old tea rose with long, pointed buds opening to fragrant soft apricot.

Deep-water 

Deep-water camellias to prolong flowering; add some seaweed to the watering can to promote plant health.

Colour 

Colour the garden with annuals. Choose from pansies, snapdragons, larkspur, primrose, cineraria and alyssum.

Care

Lift and divide summer-flowering perennials that have been left alone for a few years. Discard old, woody centres. Replant new shoots and runners from the perimeter of the clump into soil enriched with compost and manure.
