If you’ve done any reading about gardening, you’ve probably noticed USDA plant hardiness zones again and again. These zones are mapped across the U.S. and Canada and are meant to give you a sense of which plants will thrive in which area. USDA zones are based on the coldest temperature an area tends to reach in the winter, separated by increments of 10 degrees. If you do an image search, you’ll find countless examples of this map and should be able to find your own zone easily. That being said, this article focuses on gardening in USDA zone 6.

It stretches south and west through Ohio, Kentucky, Kansas, and even parts of New Mexico and Arizona before turning northwest up through Utah and Nevada, ending in Washington state.

Planting and growing zone 6 plants typically begins around mid-March (after the last frost) and continues through mid-November.
