Know Your Zone

Know Your Zone

The USDA Plant Hardiness Zone Map shows gardeners which plants are most likely to thrive at a given location within the US. First created in 1960 and revised in both ’90 and 2012: the map is based on historical weather patterns. Simply enter your zip code to find your zone.

Nearly every plant has an assigned zone, with some plants in multiple zones. Remember there are many factors contributing to a plant’s health–water amounts, soil conditions, pests and disease. GrowIt! connects you to local growers and garden centers by automatically displaying a 75 mile radius based on your home growing location. This sets you up for success, connecting you with growers facing similar conditions as yours.

Zones are broken down by 10-degrees Fahrenheit, with some further segmented into section “a” and “b” to represent 5-degree differences.

Why is your plant hardiness zone important?

All plants are different! If these zones didn’t exist, it would be extremely difficult and disappointing for people who dig plants to find out what they can and cannot grow. Almost all plants have been assigned a hardiness zone. The Zone Map helps you decide if a plant will survive in your area, be a perennial, or an annual.

*It is important to know what zone you live in before you start seeds or purchase plants.

Canada also has a zone map divided into nine major zones. Unlike the USDA map, which is based only on minimum winter temperatures, the planting zone map produced by Natural Resources Canada is divided into nine major zones with the harshest at 0 and the mildest 8, plus subzones (4a or 4b, 5a or 5b).
