Hardiness Zones

Knowing your hardiness zone is an essential part of gardening successfully. Hardiness zones provide vital information, such as average low winter temperature ranges, which help you make decisions about the plants you grow there. However, it’s also essential to know about microclimates, smaller areas with a climate different from the hardiness zone’s. We recommend starting with your hardiness zone information and then checking to see if your area falls into a microclimate. Choose your plants, and you’re ready to start gardening!
