Frequently asked questions

How do I find my planting zone?

Enter your 5-digit US ZIP code above. We return your USDA hardiness zone, your average last and first frost dates, and a planting calendar based on them.

What is a USDA hardiness zone?

A region defined by its average annual minimum winter temperature (USDA 2023 map). It tells you which perennials survive your winters and, combined with frost dates, when to plant.

What are frost dates and why do they matter?

Your average last spring frost and first fall frost bound the growing season. Most planting timing (start seeds indoors, transplant, direct sow) is measured in weeks before or after the last frost.
