Tasks for June

GENERAL

Deadhead Rhododendrons and Azaleas by snapping off the old flowers. This will give the plant a better appearance, stop seed production and promote more flowers next year. Take care not to damage the new leaf growth.

PRUNING

Prune late-spring or early-summer flowering shrubs after flowering, such as Weigela, Philadelphus and Deutzia, by thinning out up to a third of the older stems.

ROSES

New stems of climbing and rambling roses can be tied in horizontally to supports to encourage more flowers.

HERBACEOUS

Cut back spring-flowering perennials, such as Pulmonaria, to encourage a fresh flush of foliage and new flowers.

HERBACEOUS

Add plant supports for tall-growing perennials, including Hollyhocks and Delphiniums.

BEDDING

Container displays and hanging baskets will benefit from a liquid feed every week to encourage flowering or use slow release granules which will last the season.
