Alabama Plant Hardiness Zone Map

Summers are hot and humid in Alabama. You could say that Alabama has a hot and humid subtropical climate with its hot summers and mild winters.

The growing season is long, and there are significant amounts of rainfall throughout the state. Alabama vegetation is lush and thick from the warm weather, rain, and long growing seasons.

Alabama is also known for bouts of severe weather, including hurricanes, tropical storms, and tornadoes, which can be detrimental to gardens in the Alabama climate zone.

In addition, there are short winters in Alabama, so you’ll need to know your first and last frost dates before you begin planting.

Using the Alabama Growing Zones Map

Although the climate of Alabama is warm and humid across the state, looking at the Alabama hardiness zones will help you finetune your gardening plans. First, you’ll want to look closely at the map of the Alabama hardiness zones from the USDA map data of 2012.

Find your location on the map, either by looking at where you are in the state or by searching for your zip code. Next, look at the color of the area you live in, and then compare it to the legend on the right. The color that matches up to your area will tell you what Alabama gardening zone you live in.

The information from the USDA map is a general guide to help you start planning a fantastic garden. However, the area you live in may be slightly different than what the map says. Also, since the map is just a guide, you’ll need to talk to local farmers and gardeners to determine if the map is accurate for your location or if you live in a micro-climate.

A micro-climate is generally a smaller area with slightly different terrain – such as rolling hills or deep woods – that can affect the temperatures and precipitation of your site. You can also use this to your advantage by creating a micro-climate by using buildings or trees to shelter your garden from the wind or by creating hedgerows that reflect water towards or away from your garden. Again, the local gardeners and farmers in your area can help you understand how to grow in your specific location.

Alabama: A Long but Hot Growing Season

Alabama is naturally a wonderful place to grow gardens with its beautifully long growing season and plenty of rain. However, you’ll want to keep in mind that some vegetable plants just don’t thrive in the heat, so you may have trouble growing cool-weather crops such as lettuce or spinach.

However, you can focus on plenty of other plants, such as beans, peppers, and cabbage. Flowers that grow well are hyacinths, geraniums, and wisteria. And if you love trees, you’ll find plenty of pine trees and red cedars growing throughout the state. Sugar maples, serviceberry, Japanese maple, and pink dogwoods also thrive in the warm climate of Alabama.
