About Planting Zones
USDA Plant Hardiness (or Planting Zones or Growing Zones) are 13 geographical zones in the US determined by the average annual extreme minimum temperature. In simpler words, it is an area or areas with a similar range of temperature during the coldest days of the year with 1a being the area with the lowest minimum temperature and 13b being the highest.
Hardiness zone is especially important for gardeners because it decides which plant can thrive in their gardening areas.
Knowing your planting zone is the first step to starting a garden, but keep in mind that the Plant Hardiness Map alone can’t guarantee the success of your planting because it doesn’t take other factors such as summer heat level, soil moisture, humidity, the start/end of frost, the risk of catastrophic cold snap, and climate change.
