Frequently Asked Questions

What is a USDA plant hardiness zone and how does it affect my garden in Tennessee?

A USDA plant hardiness zone, often called a plant zone, is a geographic area defined by the USDA plant hardiness zone map, where certain plants are most likely to thrive. In other words, it reflects the minimum temperature a plant can handle there. This allows gardeners in Tennessee to choose plants they know will survive their local climate conditions.

How does gardening in zone 6 differ from gardening in zone 7 in Tennessee?

Each plant zone sets a different range of temperatures. The selection of plants to grow in zone 6 might differ from zone 7 because the coldest temperatures in the winter can differ by up to 10 degrees Fahrenheit. Understanding these zones helps gardeners and landscapers select plants that can survive and thrive in their respective zones.

How long is the growing season for zone 3 in Tennessee?

Zone 3 is rare in Tennessee and has a relatively short growing season due to low temperatures. Might be encountered at high elevations. The last frost date in the spring and the first frost date in the fall mark the beginning and end of the growing season, respectively. Specific dates can change from year to year.

Do All Garden Zones Tennessee Stretches Extend Across the Whole State?

No, the presence of zones can vary greatly. Zone 1, for instance, is not present in Tennessee at all, while zones like 6a and 7 cover a large part of the state. Zones are outlined on the USDA plant hardiness zone map.

Can I grow the same plants in Zone 4 that I can in Zone 5b in Tennessee?

Not necessarily. Zone 5b has a slightly higher minimum temperature than Zone 4, meaning some plants that thrive in Zone 5b may not survive the harsher winters in Zone 4. Gardeners need to check the USDA planting zone information for each plant.
