It is clear that a palm tree rated for zone 9 will not thrive in Zone 3. So think twice if you live in cold areas. The more cold-sensitive herbs have a better chance of survival if grown in a protected location. Harsh, drying winds can prove as fatal as cold temperatures to some of the less cold tolerant herbs. A winter mulch helps maintain uniform temperatures around the root system and provides protection against freezing. Mulch is an adequate winter protection for herbs such as mint and chives providing protection to minus 20☏. Most herbs benefit from a layer of mulch (pine straw, coco bean hulls, hardwood bark) during the growing season. You can also try to protect the herb plant. If you absolutely want to grow a herb that doesn’t fit your hardiness zone, you will have to grow it in a container and bring it indoors in winter. Annuals set seed and die over the course of a single season, so winter conditions aren’t typically a factor.
#GROWING THYME IN ZONE 9 HOW TO#
How to solve problems gardeners face in winterĭon’t forget that we are talking about perennial plants, not annuals. Each plant hardy zone is 10 degrees ☏ warmer (or colder) in an average winter than the adjacent zone. The zone map divides the world or the continent into separate plant hardy zones.
The lower the zone number, the colder the region. These maps are based on the minimum ten-year average winter temperatures and represent a region of minimum average winter temperatures. Gardeners need a way to compare their own garden climates with the climate their plant is known to grow well in and these zone maps help them to do this. The Department of Agriculture (USDA) of the United States has started developing plant hardiness zone maps to aid gardeners and landscapers, in the beginning for the USA and later for the rest of the world. The colder your climate, the more your plants run the risk of not surviving the winter outdoors.
When you are keeping plants and herbs outdoors, a correct selection of plants suited to your climate is a key step to successful gardening. If they can’t resist (if they aren’t hardy enough), they will die. This also means that my outdoor plants and herbs have to be capable of surviving this minimum temperature of −12.2 ☌ (10 ☏). Plant hardiness zone 8 means that, according to the USDA (US department of Agriculture), on average the minimum temperature of my zone, during winter, drops to -12.2 ☌ (10 ☏). When you are growing plants outdoors, on the patio, terrace or in the garden, it is good to have a clear idea about the climate you live in. Do you have an idea in what zone you live in?Īnd why is that important to know you may ask! Plant hardiness zones explained I live in Belgium which is in plant hardiness zone 8. how to solve problems herb gardeners face in winter.I will show you how to make a correct herb selection for the outdoor herb garden based on hardiness zones. Have you ever heard or read about hardiness zones for plants and herbs but you don’t really get it?
