We know that with information all your questions will be answered. Find in this article an incredible review of Garden Zones! From the basics of garden zones to know how to read the garden zone map. All you need to know about garden zones: how to use the USDA map!
Gardeners use the USDA plant hardiness zone map to have a clear understanding of which plants are better for their location and temperature. By using this map you will save tons of money and time. What is the USDA? USDA stands for United States department of agriculture. This department of agriculture comprises food, natural resources, agriculture, nutrition and rural development.
Going back to our main topic, let´s see what is meant by plant hardiness: it is the ability that a plant has to remain alive under hard climate conditions like droughts, floods, cold and hot. The plants´cells (the eukaryotic cells) contain all the information about plants: whether they will survive hard climate conditions or not. Also, they determine where they will grow healthy depending on what they need.
Getting to know the hardiness of a plant takes time, all of them are different and it is easier to know what they need to grow: light, water or a moisture soil? Everything becomes easier when you have access to a growing zone map.
The zone map contains the garden zones of United States. Each garden zone is a geographic area that has a range of annual minimum temperature: essential to know the ability to survive of a plant. The most used garden zone in the world is the one appearing in the picture, it has been created by USDA. It contains thirteen different garden zones with an average of minimum temperatures of each zone.
What is the purpose of this map? Getting to know the hardiness of the plants depending on the area you live at. Make your decisions based on facts and not on assumptions.
The garden zone tends to refer to the USDA scale found on the right side of the picture. Gardeners tend to say when speaking about a plant: "this plant is hardy to zone 9", meaning that the plant can resists a temperature of 20 ° F to 25 ° F. When you understand the concept of a garden zone and you are able to read the map, then it is time to make the decision: which plant suits best in your area?
As I explained before, there are thirteen garden zones in the map of the USDA including USA, Alaska, Hawaii and Puerto Rico. The thirteen zones cover a range of 10 degrees. So that you know, zone 1 is the coldest and zone 13 is the hottest. Let´s see an example: zone 1 has a minimum temperature of -60° F to -50° F degrees. While zone 13 has a minimum temperature of 60 to 70 degrees.
Now that you got to know the garden zones, it is time to decide what plants you will choose for your garden. Knowing the extreme minimum temperatures of each zone, will let you know if your plant will survive the winter or not. The goal of the garden zones map is assuring a gardener in Hawaii that he is choosing the correct plant for his area depending on the weather conditions of his area. Gardening is a relaxing activity for everyone. Being in contact with nature everyday reduces your stress levels: go out to your garden, to the nearest park or to your balcony full of plants.

As I mentioned above, zone 1 is the coldest garden zone of the whole map made by USDA. Temperatures here are extreme: -60° F to -50° F degrees. As you may be thinking now, it is an extremely difficult zone to plant due to the weather conditions. Most of garden zone 1 is located in Alaska. However, there are plants whose hardiness fits with extremely low temperatures. They need to have cold tolerance and drought tolerance too. Rain lacks in that type of arid places.
Let´s see what plants are perfect for this kind of environment! Native plants are already used to low temperatures and they developed skills to do so. They are always a good idea to continue planting. Most of the people who live in garden zone 1 tend to plant inside their houses or in greenhouses.
