Spring bulbs should be in the ground by now; plant any remaining bulbs, especially tulips, which can be planted later than other bulbs.
Lift dahlias, begonias, and gladiolus in frosty localities to prevent damage, or cover them with soil in milder areas.
Bulbs in pots to be forced for indoor use can be taken out of the ground and moved into a greenhouse or a cool bright area indoors, and then into a warmer place to flower.
Bedding Plants and Perennials
Plant bedding plants for spring color now, if not already done.
Plant new perennials if the ground is not too wet; avoid division and replanting if the ground is wet, as many flowers react poorly to being moved into cold, wet ground.
Perennial flowers can be planted now unless the ground is sodden; division of existing plants can also be carried out.
Maintenance and Weeding
Remove seedling weeds from any autumn-sown hardy annuals.
Containers and flower beds can still be planted up with spring bedding, such as wallflowers and tulips.
Most perennial flowers can be lifted and divided or new specimens planted, but do not do this if the soil is wet and sticky; avoid moving grasses at this time.
