  • Why is your Last Spring Frost date important?
    When planning a spring garden, this is square one. Most all seeds come with instructions on when to sow, and most of these instructions are relative to the sower's last Spring frost. Mark this date as a banner day on your gardening calendar.
  • Why both an early & late fall frost date?
    Some veggies you will harvest once in the fall like pumpkins. You need to know the earliest probable frost for your area to make sure you sow those seeds with time to harvest before the first fall frost.

    Then there are some veggies you will harvest continually until the first frost in fall. The late date tells you the latest you can plan to harvest these plants given a late frost.

  • Do you live in a micro-climate?
    Sometimes local geographic features, or even living in an urban area where there is a lot of concrete, can change the climate of an area on a micro level. Keep that in mind while you browse your search results.
