Gardening Zones in North America Custom Search Gardening zones in North America map
Gardening zones are areas of North America based upon average lowest temperatures and are delineated by the U S D A in a map form for everybody's guidance. Once you know your particular gardeningzone, you will be able to choose only the plants and seeds that will grow in your zone of the country. When buying your seeds or plants for planting, always check to see what zone they are adapted to. This will save you a lot of heartache down the road. The rules for these zones are not hard and fast and they will vary significantly even at locations only a few miles apart due to natural conditions such as proximity to a large body of water, a large metropolitan area, its altitude and whether your site has good orientation to the sun. Due to the fact that this map does not show any dates, keeping a log of not only what you plant, but when you plant, and the actual dates of the first and last frosts, will provide you with excellent information for future crops. Experimentation and experience will tell you what plants will work and which won't. Some crops can be planted before last frost, some just after the last frost and some when the soil is warm enough. Your seed catalogs and your log will give you the backup information needed regarding this timing and will help insure a successful crop. The gardening zones map is self-explanatory and even gives specific locations as a further guide. Although this particular map is published by The National Arboretum and relates primarily to trees and ornamental plants, the zones are common to all vegetation throughout the areas shown.
