SLUG Garden Calendars These two calendars are meant to help you plan garden maintenance activities in a timely manner. The top calendar is SLUG's official calendar, and the one below tracks the progress of the Umana-Barnes Middle School's garden.

APRIL
  • If your school has plans for a summer garden, April is a good time to start seeds inside under lights for transplanting outdoors.
  • Cool season crops like spinach, mache, turnips and chard can be direct-sown in the garden during April.

MAY
  • Even if the weather seems nice, try to resist the urge to start planting warm weather crops! The Boston-area climate can turn on you very quickly, and an unexpected cold snap will hurt your delicate crops. Wait until after the last estimated frost date (May 23rd) to plant tomatoes, corn, peppers, melons, cucumbers etc. outside.
