- Reseed or resod lawns through mid-month.
- Begin pre-emergent weed control on lawns and in flower beds. However, consider that flowering weeds provide food for important pollinators.
- Mulching is an earth friendly alternative in flower beds.
- Clean up perennials, removing dead leaves. Waiting until now has saved many overwintering beneficial insects.
- Spray new growth on bearded iris with imadacloprid to control borers through early April.
- Apply dormant oil spray to fruit trees and ornamentals to control overwintering insects.
- Certainly pick those lovely daffodils, but leave foliage intact.
- Freshly cut daffodils produce a chemical that injures other flowers in a mixed arrangement. Isolate them in water for a day, then rinse the stems before mixing with other flowers.
- Fertilize spring bulbs as flowers fade.
- Prune floribunda, grandiflora, and hybrid tea roses. Remove dead, crossing and inward facing stems. Begin fertilizing as buds break. Plant bare-root roses now.
- Do not prune forsythia, quince, and other spring blooming shrubs until AFTER flowering.
- Continue planting snow peas, garden peas and kale. Irish potatoes, cabbage, broccoli and cauliflower transplants can be put out at the end of the month.
- Floating row covers will protect against insects and light frosts.
- Remove mulch from strawberry beds when flower buds appear.
- Warm season vegetables (eggplant, tomato, peppers) can still be started indoors from seed.
- Divide and transplant summer perennials and ornamental grasses as new growth begins.
- Prune evergreen shrubs back to a manageable size before new growth begins.
- Get your soil tested. The County Extension Agency has soil test boxes and instructions.
