What is the map of the hardness zone?

Map of hardness zone is a map that divides the US or any state or other country into zones based on the coldest temperature. These maps can be very useful for gardeners because they provide one hint of how well the plants grow in a particular area and whether the temperature would be so cold that it could kill certain plants. By knowing where you live, you can look at the hardness zone map (there are many online) and find out if the plant you want will grow well or die in your zone.

In fact, there are several versions of the hardness zone for different areas. In the US, Plant shops can use the USA hardness map (USDA), but in some Western United States, some shops are still undergoing a climate map of Sunset Magazine, which was developed more than forty years ago. If you order from the seed catalog or gardening and live in western state, you may want to find out which criteria are using the catalog or according toOutfly.

The

Map of the USDA zone is based on climate formula studies for more than ten years, but the map was last updated in the early 90s. It divides the US into eleven climatic zones. Zone 1 may mean that temperatures reach lower-50 F (-45.56 ° C). Zone 11 means that temperatures do not drop below 40 ° C (4.44 ° C). In the huge amount of land that makes up the US, there is a significant change in climate, and each consecutive zone slightly increases the lowest temperature.

There may be very complex forms of hardness maps and some get into extreme details, even in a state. For example, California has several zones. The lowest temperature in the Sierra Mountains will be completely different from San Diego than the temperature.

plants are then evaluated by the zone to tell those who choose them if they can expect the plant to be well done to the lowest temperature in the Their. Sometimes on the zone does not go muchIt is, especially when you grow annuals like pansies or impatiate. As long as you have relatively warm summer temperatures, these plants will be well. When planting perrenials, plants that last year after year, you want to make sure the plants are resistant enough to survive low temperatures in your area and live to bloom for another year.

While gardeners say that the hardness of the zone can be useful, it is not the only consideration in the selection of plants. Different types of soil will help plants grow or prevent them from prosper. It is necessary to consider the amount of light, wind, precipitation and many other factors.

What can achieve the map of the resistance zone is to provide you with basic ideas about what plants will be well in your area. Once you become more experienced in the horticulture, you have to think about the needs of any other type of plants. When they are well tune of your horticultural skills of soil, water needs and needs to reduce pests or weeds you will be able to boast of most of the plants you growAnd how well they are doing.
