Perennials: Many perennials can be propagated — by division, cuttings or self-seeding. For certain perennials division must be done in the spring: alchemilla, asarum, centranthus, echinacea, eupatorium, geranium, heuchera, pulmonaria, stachys and stokesia, to name a few. Others can be done in spring or fall.
Flowers: Tuberous begonias may be started this month. Plant in individual peat pots. Keep out of direct sun but in good light. Maintain a lightly moist soil that barely dries out but is never wet.
Vegetables and fruits: Set aside a potting area for seed starting and gather the necessary equipment such as sterile seed starting mix, trays and pots. You may also want to try an electric heating mat, which speeds germination. Carefully clean flats and pots with a 10 percent solution of bleach. Post a seed-sowing schedule so that you can sow the seeds at the right time to produce healthy plants in time to move outside in after the last frost.
Trees and shrubs: Do not prune maple, beech and dogwood now because the trees “bleed” or lose sap. Wait until summer when they are in full leaf.
Lawns: Consider reducing the size of your lawn and substituting a wildflower or native plant border or perennial grasses or other drought-tolerant plants.
Houseplants: Begin feeding houseplants with a balanced 20-20-20 solution at half strength as they begin to stir out of winter dormancy. This is a good time to root cuttings of geraniums, coleus, begonias and ivy.
General: Did you buy your valentine a gorgeous red flowering plant? If you buy roses, inquire whether they have been grown without pesticides.
