By understanding what zone you’re located in, you can find out which plants will grow best in your area and which won’t. Knowing which planting zone you are located in can impact your gardening success in tremendous ways.
It’s common for people to look at the USDA Plant Hardiness Zone Map and assume it would be divided out by region. We commonly perceive certain states as sharing similar climate conditions.
We’ll share more with you in the next section how the USDA Plant Hardiness Zone Map is determined. It’s more accurate to use planting zones because it’s measured by the climate which can be different in areas in proximity to each other.
Allow the tool to use GPS to determine your location, then the map will show your planting zone. The USDA Hardiness Zone Map was created by collecting data from news stations around the United States.
Once the data is in, the process starts with determining the average minimum annual temperature per area. 1A is the coldest zone in the US which averages a minimum winter temperature of -60 degrees Fahrenheit.
13B is the warmest zone which averages a minimum temperature of 70 degrees Fahrenheit. If that’s the case, check you frost dates and get a time in the year when it would be safe to plant in your zone.
For instance, it’s common for people in parts of Alaska only to have a three-month growing season. Whereas people in zone seven through ten can produce a variety of plants practically year-round.
You should test for soil pH and make sure it’s at the proper level for the plants in your garden. Also, be sure to amend your soil with compost and other organic matter to help make it fluffy and well-drained.
The rule of thumb is to give your plants one inch of water per week. It’s a good idea to place your garden where it’ll get at least six hours of sunlight per day.
That leads to different temperatures and planting times, but they all have to face certain weather conditions common to their area. This mostly happens in heavy urban areas where buildings absorb the sun’s energy and radiate the heat to the air, which makes the temperature higher than the zone average.
Understanding what weather threats are common in your region can help you better prepare your garden. All of these factors can be considered and planned for to give your garden the greatest chance of success.
And normally local stores wouldn’t sell seeds that can’t grow in the area. On the other hand, if you live in warm zones, you might be able to grow some annuals as perennials.
Many people in colder locations use greenhouses to prolong their growing period. It is a great way to start seeds earlier and produce crops later. Even if you don’t live in an freezing zone, you can still use a greenhouse to grow vegetables over the winter to keep the frost off of them.
If you learn to garden from the internet or books, check if the guide is zone -specific. Be careful, most authors of gardening tutorials don’t realize if their tips can only be applied in some zones.
Here at MorningChores, we specifically create guides and tips for each zone, so you won’t make the same mistake: Being able to understand a hardiness zone map means you’ll have a starting point for making wise planting decisions.
Understanding gardening zones means you can focus your time and attention (not to mention money) on plants with the best chance of winter survival. Planting Zone Map for 2019 combines data from the USDA with specific geographical information to provide a complete look at your growing area.
Instead of simply assuming you are in a certain zone and thinking you already know what grows best, click on the major metros near you to see detailed information specific to your exact area. By clicking your closest metro area, you’ll find even more detailed information to help make your gardening decisions.
Each cultivar of a plant may have different hardiness levels based on their adaptations and genetics. For example, the cold may cause your beloved perennial to die; however, the roots might be hardy enough to bring new growth in the spring.
You can adjust many things, such as soil type, moisture levels and amount of sunlight in your garden, but temperature can be hard to control. In the simplest terms, USDA hardiness zones keep a grower in Alaska from making the mistake of planting peach trees.
Understanding the different plant hardiness zones gives you the ability to narrow down your gardening choices. Use the information about individual growing zones as a starting point for planning what to plant in your garden.
With minimum average temperatures between -60 to -50 degrees F, it can be a difficult zone for gardening. Native plants have already adapted to the area, so it makes sense that they’re a natural, excellent choice.
While there are relatively few non-native perennials suitable for Zone 1, some can be grown with proper planting and care. Giving plants a head start indoors or in a greenhouse typically results in better success for Zone 1 vegetables.
Located in both Alaska and the continental United States, planting Zone 2 features freezing average minimum temperatures of between -50 to -40 degrees F. These temperatures can present a growing challenge to many gardeners. High winds and drought conditions are found in both the tundra and plains of Zone 2.
Plants in Zone 2 must be able to withstand freezing and high levels of drought. Annuals are best suited for this zone, but some perennials can be grown when chosen carefully.
Bleeding Heart Monkshood Pension Poppy Primrose Sea Holly Violet Plant hardiness Zone 3 is found throughout Alaska, the northern portions of the United States and in high altitude areas.
This zone features minimum average temperatures of -40 to -30 degrees F. Depending on the geographical location of your growing space, high winds, freezing and low moisture may affect growing conditions. Most native plants can be grown across the zone, regardless of altitude, as long as growing conditions are similar.
These unique climates share minimum average temperatures of between -30 to -20 degrees F. Planting in this zone is less challenging than in colder zones, but the short growing season impacts both vegetables and flower bloom times. Zone 4 is considered a cool climate suitable for growing plants hardy enough to withstand temperatures well below freezing.
Plant hardiness Zone 5 includes the southern coastal region of Alaska, the North Central United States and portions of New England. With minimum average temperatures between -20 and -10 degrees F, this zone experiences a moderately cold winter.
While the growing season is short, you can extend it by using cold frames or using started plants in your annual garden. From coastal waters and woodlands to the wide plains of the Midwest, plants should not only be cold hardy, but they also need to match the growing environment.

False sunflower Florida rose Flowering fern Japanese Bottle brush Lady’s Mantle Serum This zone features cool winters with average minimum temperatures falling between 0 and 10 degrees F. Gardens in this zone have multiple plant options from seed catalogs, local home stores, nurseries and greenhouses.
Zone 7 contains many growing climates, from the Eastern coastal areas through the Oklahoma prairies to the arid regions of the southwest and up into the forests of Oregon and Washington. The region’s wide variety in climates means that other considerations often need to be made to accommodate for drought tolerance and to adequately adjust soil conditions.
Many Zone 7 hardy plants can be grown successfully in multiple locations with adjustments made to address their specific needs. Providing row covers or cold frames can help protect against early spring or late fall damage.
Extending up the western coast, Zone 8 features average minimum winter temperatures of 10 to 20 degrees F. With hot summers and mild winters, growers typically enjoy a long planting season. Plants hardy for Zone 8 love mild winters and long, hot summers.
With a wide range of moisture and sunlight requirements, growers should narrow down a potential plant list first by zone, and then by specific growing climates. Cool weather plants like spinach, lettuce and peas can be grown in both the spring and the fall.

Asiatic lily Hardy geranium Santana Mexican petunia Phlox Located in California, Arizona, Texas, Florida and along the Gulf of Mexico coast, this zone features warm winters and hot summers.
With an average minimum winter temperature of 20 to 30 degrees F, Zone 9 features active gardens throughout the entire year. Long, hot summers and mild winter conditions make the heat more of an issue than the cold in this zone.
Tropical plants with low water requirements thrive in Zone 9. Apples, pears, peaches and cherries require colder weather than Zone 9 provides.
Basil Bay laurel Chives Coriander Lemon thyme Marjoram Mint Cold-hardy plants perform well during the mild winters, while tropical perennials are the centerpieces of long, hot summers.
Southern inland California, southern Florida and Hawaii are the three small areas where the average minimum winter temperature only falls between 30 and 40 degrees F. The ability of Zone 10 gardeners to avoid freezing temperatures is a huge bonus for winter gardening, but the extreme heat of the summer months limits planting possibilities. With few frosts, the high heat and humidity of summer can become a major concern for growers.
Curry leaf Warangal Ginger Mexican tarragon Miracle fruit Planting Zone 11 is found in Hawaii, the Florida Keys, Puerto Rico and a few small areas of the Continental United States.
This extremely warm zone features mellow winters with an average minimum winter temperature of between 40 and 50 degrees F. Cold hardiness is not a factor in this zone, since it has zero frost days. With long, hot summers and warm winters, Zone 11 growers need to look for plants that are heat tolerant.
Anemone coronary Begonias Bougainvillea Drumstick gallium Kangaroo paw Ponytail palm Planting Zones 12 and 13 are not found in the continental United States, but are located in both Hawaii and Puerto Rico.
Tropical plants are the key to gardening and landscaping in the extreme heat of both these zones. Growers germinate indoors, purchase plants from nurseries and grow many vegetables during the cooler winter months.
Bush beans Eggplant Hot peppers Summer squashes Tomatoes Flowers to Grow in Zones 12 and 13 With the proper care, many tropical plants will bloom beautifully in this hot climate.
