Most gardeners are familiar with temperature-based hardiness zones. These are set out in the United States Department of Agriculture plant hardiness map that divides the country into zones based on the average lowest winter temperatures. But cold temperatures are not the only factor relevant to how well plants grow.
You will also want to learn about different climate types
and climate zones. What are climate zones? Read on for information about
gardening with climate zones.
What are Climate Zones?
Plant hardiness zone maps were developed to help gardeners
figure out in advance which plants could survive outdoors in their region. Many
plants sold in nurseries are labeled with a hardiness range so that gardeners
can find appropriately hardy selections for their garden.
While hardiness to cold weather is one factor that impacts a plant’s health in your garden, it isn’t the only factor. You also have to consider summer temperatures, length of growing seasons, rainfall, and humidity.
Climate zones have been developed to include all these
factors. Those gardening with climate zones take these gardening climates into
account when selecting plants for their backyard. Plants usually do best in
regions with climates similar to their native areas.
Understanding Climate Zones
Before you begin gardening with climate zones, you need to
understand different climate types. Your climate zone will also impact the
plants you can grow. There are five main types of climates, with climate zones
ranging from tropical to polar.
- Tropical climates – These are hot and humid, with high average temperatures and lots of precipitation.
- Dry climate zones – These zones are hot but dry, with very low precipitation.
- Temperate zones – Temperate zones have warm, wet summers with rainy, mild winters.
- Continental zones – Continental zones have summers that are warm or cool and cold winters with snowstorms.
- Polar zones – These climate zones are extremely cold in winter and quite cool in summer.
Once you start understanding climate zones, you can use them
for gardening. Gardening with climate zones in mind simply means that gardeners
only introduce plants that match their specific gardening climates.
First, you want to identify your own climate and climate
zone. Several different climate zone maps are available to help you with this.
Gardeners in the western United States, for example, can use the 24-zone climate system created by Sunset Magazine. The Sunset zone maps take into account both average winter lows and average summer highs. They also factor in growing seasons, humidity, and rainfall patterns.
The University of Arizona Cooperative Extension put together
a similar plant climate zone system. The zone map is similar to the Sunset map,
but it uses different numbers. Your local
extension office should be able to help you locate suitable climate zone
maps for your area.
