In early to mid-spring, plant summer-flowering bulbs in prepared ground or in containers indoors or outdoors. Snowdrops may be planted 'in the green' (still in leaf).

Water and feed established bulbs and deadhead spent flowers. Any tall plants grown in pots should be supported with canes and ties. Re-pot or top-dress bulbs in containers.

In late spring, cut the grass in areas where naturalised bulbs grow; wait until at least 5 weeks after the plant has stopped flowering or until the foliage has turned yellow. Lift and divide clumps of bluebells after flowering, whilst you can still see the foliage.

If propagating plants, collect the ripe seed of early-flowering bulbs, or take basal stem cuttings of dahlias and begonias. Dahlia tubers may be lifted and divided.
