Frequently asked questions
How do I find my last frost date?
Local extension services and many weather sites list average frost dates by ZIP or postcode. Frost-free dates vary even within a region.
What if it's an unusually cold spring?
Frost dates are averages. For warm-season crops (tomatoes, peppers, squash) wait until nights stay above 50 °F (10 °C).
Can I plant again in fall?
Yes — cool-season crops like lettuce, spinach, kale and radishes can be sown 6–10 weeks before your first fall frost.
