What are the USDA zones?
The United States Ministry (USDA) provides gardeners in North America a number of links, including a map of hardness that gardeners can use to determine what kinds of plants in their area are likely to prosper. USDA zones are divided by temperature: each zone is 10 degrees Fahrenheit (approximately five degrees Celsius) cooler than the zone below it on the map and much warmer than the zone above it. Many plants are tested by hardness and report the USDA zones in which the gardeners can decide what to plant and when. The first resistance map was released in 1960 and was constantly updated until 1990, when significant changes were made, including the addition of 11. Zones to the original 10. The USDA two to 10 zones were further divided to reflect the temperature dispersion of five degrees, which can cause a big difference. Because of this division, and Total Leafof the USDA ZONES STARTS WITH ZONE ONE, THE COLDEST, WITH Temperatures That Can Reach -50 Degrees Fahrenheit (-45.6 Degrees Celsius) and Goes Through USDA Zones 2a, 2b, 3A, 3B, 4A, 5A, 5b, 6A, 6b, 7A, 7b, 8 9a, 9b, 10a, 10b and 11, the hottest, with a winter temperature that exceeds 40 degrees Fahrenheit (4.5 degrees Celsius).
As soon as the gardener determines the zone of consultations with the local garden shop or using the search engine tools on the Internet, plants can be sought that will prosper in this zone. Information on the designation of the plant on the plant usually suggests in which USDA zones the plant can winter, as well as USDA zones in which the plant can be grown if it is in the greenhouse during the worst cold. For gardeners living in cold areas where many plants have problems during Winter, the USDA zones will pull a large amount of guessing from the horticulture.
USDA zoneshave some shortcomings. Although they take into account average temperatures, they do not look at things like humidity, heavy rain, high wind, daily length and altitude. This means that information may not always be accurate for your zone, especially if you live at a high altitude; Local garden shops can usually make stronger recommendations for plants that will be good, as well as other gardeners living in your conditions. In addition, numerous gardening forums discuss the hardness of plants in different conditions and can be more accurate standards, especially if you live in Western states. Western gardeners can also use maps of western climatic zones of sunset because they include multiple factors.
