Whether you want to grow flowers, vegetables or shrubs in your garden, knowing your planting zone will help you succeed. A zone map categorizes regions based on their average winter temperature, and it is crucial for helping gardeners and farmers choose plants that will thrive in their climate conditions. Using the USDA Plant Hardiness Zone Map as your guide, you will know which species are likely to survive in your region. This information will also help you determine when to start seeds, and when your average first frost and last frost dates are.
Gardeners in zone 8 have the ideal conditions to grow a wide variety of flowers, herbs and vegetables. This area has hot summers and long growing seasons, as well as mild winters. There is a large range of vegetables that can be grown in this climate, including tomatoes, beans and peppers, as well as fruits like apples and peaches. Herbs, such as thyme and parsley, are also a great choice for this zone.
If you want to add some variety to your flower garden, there are a wide range of perennial plants that will flourish in this climate, as well as many beautiful shrubs and trees. A variety of blooming tulips, sweet williams and lilacs are good options, as are deciduous trees like oak, maple and sycamore. In addition, there are plenty of fruit trees that can be grown in this zone, including figs and avocados.
When shopping for plants, be sure to check the label and look for the zone number. Using the USDA plant hardiness zone system as your guide, you will be able to select only those that can survive your cold winter temperatures. This will save you money on new plants that could be damaged by cold weather or a late frost.
The USDA plant hardiness zones are updated annually to reflect new weather data. When the latest maps were released in 2012, many zones were moved up by a few degrees. Some gardeners have questioned this change, and wondered whether it was a result of global warming. However, the National Gardening Association suggests that the increase in zones may simply be the result of better technology and more local weather stations contributing data to the process.
In addition to the USDA plant hardiness zone maps, there are other standards that can be useful for determining what will thrive in your area. For example, the American Horticultural Society’s heat-zone standard is becoming more common.
In some cases, a gardening zone is divided into two half zones to represent a more detailed temperature gradient. For example, in the northern part of the country, zone 5 is split into two subzones, 8a and 8b, with each having a different average minimum winter temperature. Understanding your subzone will allow you to make more precise planting decisions, as some plants need to be sown indoors in order to mature at the right time for outdoor gardens.
