Tasks for May

Weeding is now an all consuming job, keep on top of it with regular hoeing. Dead head daffodils where possible but never tie the leaves, or cut them down before they have turned brown.

Prune spring flowering clematis after flowering.

Stake tall or floppy herbaceous plants, especially dahlias whose stems are brittle.

Bedding plants can be planted out towards the end of the month, after the last frosts have passed. Ensure they are gently acclimatised to the change in temperature outside the greenhouse or cold frame.

Trim back spreading alpines such as aubrietia and arabis after flowering.

Set up that water collection system, eg a water butt connected to the guttering, for easier watering over the summer.
