Key takeaways

What to know before you act on this, from the SteadScape editors.

  • Start topping indeterminate tomatoes and cucumbers about three weeks before your area's average first frost date to maximize ripening.
  • Harvest all cold-sensitive vegetables like tomatoes and peppers at least one week before the first frost to prevent damage.
  • For herbs like basil, which are sensitive to frost, harvest and preserve them before temperatures drop below 40°F.
  • Pot up perennial herbs such as rosemary and thyme in early fall, ensuring they have drainage holes and fresh potting mix for indoor overwintering.
  • Monitor your local frost dates using an interactive tool to better plan your garden preparations and avoid surprises.
