Planting & Growing Hardiness Zones For Gardening
Gardening isn’t always about sunny days and clear skies. Sometimes, well, depending on where you are located, snow and drastic climate can also arise. So be prepared! You have to be equipped with the knowledge about the right plant, the right place and the right time, oh and let’s not forget the right temperature. That’s what the USDA hardiness zones are all about. As per Wikipedia: “It is a geographically defined area in which a specific category of plant life is capable of growing, as defined by climatic conditions, including its ability to withstand the minimum temperatures of the zone.” So if you want to find out more about gardening hardiness zones, let this infographic be your guide.

What are Hardiness Zones?
Hardiness zones were developed by the USDA to define 11 numerical climate zones and the ability of certain plants to grow within those zones. Seed packaging and plant labels indicate which zone your plant is most likely to thrive in, so identifying where you live is vital to the planning of your garden.

Planting Plan
Tulips pushing through soil or forsythia budding are great indicators that it’s warm enough for seed planting.
Zones 2-3
Winter hardiness is very important in these zones. Choose plants that can withstand harsh winters and hot summers. Ideal for Carrots.
Zones 4-5
Native plant species are highly recommended due to the varied micro-climates and altitudes in these zones. Ideal for Lettuce.
Zones 6-7
Ideal climate conditions for vegetable gardens. These zones may produce 3 seasons of crops for gardeners. Ideal for Squash.
