To-Do List for Zone 3

  • Plant new fall bulbs so they develop roots before the ground freezes.
  • Harvest corn, potatoes, apples, cucumbers, tomatoes, squash, and strawberries before a killing frost.
  • If tomato vines are covered with green fruit, pull up whole plants and hang them in a basement or garage until fruits ripen.
  • After onion tops have fallen over, dig the bulbs and let them cure on the soil surface for about a week before you store them.
  • After harvesting, spread compost over the soil surface.
  • Rake leaves and clean up plant debris, then add them to the compost pile.
