Know Your Growing Zone.

WhatsMy.Zone helps gardeners, growers, plant sellers, landscapers, farmers, and developers understand local growing conditions anywhere in the world. Instead of showing only a general climate label, the service combines USDA Hardiness Zone data with practical frost information: estimated last frost date, first frost date, frost-free season length, and frost-safe planting period.

This matters because plant hardiness is only one part of successful growing. A location may have a suitable winter minimum temperature for a perennial plant, but still have a short growing season, late spring frosts, early autumn freezes, or a frost pattern that makes timing difficult. By combining hardiness zones with frost dates, WhatsMy.Zone gives a more useful picture of when plants can safely grow outdoors.

Many existing USDA zone maps focus mainly on the United States or use broad regional data. Our hardiness zone finder is built for global use, so you can check growing conditions for cities, villages, gardens, nurseries, farms, balconies, greenhouses, and delivery destinations around the world.

The data is delivered on an approximately 1 kilometre grid, helping the service reflect local climate variation more precisely than broad national or regional maps.

Climate is changing, and hardiness zones are shifting. Accurate and recent climate data is becoming more important for gardeners, landscapers, growers, farmers, and green space managers who find that traditional planting recommendations no longer fully reflect current conditions.

WhatsMy.Zone uses recent climate-based calculations to provide information that is better aligned with modern growing, landscaping, agriculture, plant shopping, and green area management.
