  1. Begin indoor sowing: begonias, geraniums, and pansy

    Your window is short. These crops want several weeks of indoor growth before they go outside.

  2. Harvest basil, carrots, and cucumber as they ripen

    Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
