March is a good time to divide and re-plant your perennials like hardy geraniums, crocosmia (montbretia), hostas, solidago (golden rod), astilbe and peonies. Snowdrops can be divided too.

Start taking cuttings of dahlia and outdoor chrysanthemums.

Prune back large flowering clematis, roses and early flowering shrubs.

Slugs and snails will be out at night as the temperature rises, nibbling at the lush green shoots. Get some slug pellets down as soon as new shoots appear, especially on hostas.
