Early in the month:
- Start seeds indoors of slower-growing annuals that you should start 10-12 weeks before the last average frost date. These include snapdragons, annual salvias, and impatiens.
- In the second half of the month:
- As temperatures and soil moisture allows: Direct sow seeds of fast-germinating cool-season vegetables, such as radishes, spinaches, and lettuces, and onion plants.
- Divide any perennials that are an inch or so high and don't bloom in very early spring.
- If you didn’t do it in the fall, apply compost to perennial, annual, and vegetable beds.
- Clean up perennial beds that didn’t get done last fall. Rake up late fallen leaves that have accumulated around plants.
- Uncover mounded roses and clean up dead/diseased foliage as soon as new growth begins to swell.
- As soon as the snow melts, rake up leaves that remain on the lawn. Begin mowing as soon as necessary.
- The last week of March or first week of April: Start seeds indoors of annuals that you should start 6-8 weeks before the last average frost date. These include marigolds, globe amaranth, sweet alyssum, flowering tobacco, peppers, tomatoes, and eggplant.
- Cut back ornamental grasses to 2-3”.
- Start visiting the Garden Center to see the early arrivals.
