Mow lawns low to remove old growth before new growth begins.
Loosen winter mulches from perennials cautiously. Re-cover plants at night if frost returns. Clean up beds by removing all weeds and dead foliage at this time.
Heavy pruning of trees should be complete before growth occurs. Trees should not be pruned while the new leaves are growing.
Delay planting if the garden soil is too wet. When a ball of soil crumbles easily after being squeezed together in your hand, it is dry enough to be safely worked.
Ornamental grasses should be cut to the ground just as the new growth begins in mid-to-late March.
Spring bedding plants, such as pansies and toadflax (Linaria sp.), may be planted outdoors in mid-to-late March.
Plant beets, carrots, parsley and parsnip seeds outdoors.
Gradually start to pull back mulch from rose bushes.
Start seeds of tomatoes, peppers and eggplants indoors.
