United States in Hardiness Zone 8 In North America, Zone 8 is one of the warmest zones, containing much of the southern quarter of the United States, including much of North Carolina, South Carolina, Georgia, Alabama, Mississippi, Florida, Louisiana, Arkansas, Texas, Arizona, California, and the Oregon and Washington coast. Zone 8b means the average minimum winter temperature is 15 to 20 °F. Zone 8a has an average minimum winter temperature of 10 to 15 °F. Plantation zone 8 is one of the warmest plant hardiness zones, with mild winters and long, hot summers.
Extending along the West Coast and covering much of the United States, Zone 8 has an average minimum temperature of 10 to 20 degrees F. Due to mild winters and warm summers, your Zone 8 growing calendar will give you plenty of options for your vegetable and flower garden. Try growing watermelon to enjoy during the summer months and pumpkins for the fall harvest. In Zone 8, the options are unlimited.
When you grow plants in Zone 8, you can plant most of the known garden vegetables, sometimes even twice a year. The only way to grow something is if you have added cold frames, greenhouses and bells to your garden repertoire. In these months, the weather is so hot that most gardeners “take the summer off” planning to harvest their crops for June. Instead, a heat zone (see below) is defined by high annual temperatures; American Horticultural Society (AHS) heat zones use the average number of days per year when the temperature exceeds 30 °C (86 °F).
Zone 4 is located between the Arctic Circle and approximately between 64 and 66° N, with cities such as Oulu, Rovaniemi and Jokkmokk, zone 5 (south to 61-62° N) contains cities such as Tampere, Umeå and Östersund. Zones are defined by steps of 5 degrees Celsius, -15 to -10 °C for zone 1 to 15 to 20 °C for zone 7.Zone 6 covers the south of mainland Finland, Sweden north of 60° N and the Småland high plateau further south. Area information alone is often not adequate to predict winter survival, as factors such as frost dates and snow cover frequency can vary widely between regions. Planting by USDA area is a good starting point to understand what you should think about planting and when.
As an extreme example, due to the Gulf Stream, most of the United Kingdom is in zones 8-9, while in the United States, zones 8-9 include regions such as the subtropical coastal areas of the southeastern United States and the continental deserts of Mojave and Chihuahua, so a gardener American in that area will only have to plan for several nights of cold temperatures a year, while its British counterpart may have to plan for several months. The warmest zone of the 48 contiguous states is the Florida Keys (11b) and the coldest is in north-central Minnesota (2b). Plants that are hardy in Zone 1 accept colder temperatures, while plants in higher zones only survive in warmer areas. There are many other climatic parameters that a farmer, gardener, or landscaper may also need to consider, such as humidity, rainfall, storms, rain-dry cycles, or monsoons, and site considerations such as soil type, soil drainage and water retention, water table, slope to or away from the sun, natural or artificial protection against excess sun, snow, frost and wind, etc.
Other resistance rating systems have also been developed, such as the Royal Horticultural Society systems of the United Kingdom and the Sunset Western Garden Book systems of the USA. UU. The Australian National Botanical Garden has devised another system more in line with Australian conditions. In general terms, resistance zones are high considering the latitude of the region, although not as high as northern Europe with the Shetland Islands, where zone 9 extends to more than 60° N.
