If you’re located in Zone 6 and need some planting and care tips, check out our growing guide below for your area so you can grow confidently!
Where is Zone 6?
The USDA Hardiness Zone 6 runs through 38 states in the U.S., beginning in the east in southern New England and stretching south, encompassing Ohio and brushing into the northern Texas panhandle. It then curves northwest from New Mexico through Utah and Nevada to eastern Oregon and Washington.
Zone 6 experiences true winters and summers, making it friendly to a wide variety of flowers, shrubs and trees. And like other hardiness zones, it comprises two subzones—6a and 6b—that are separated by a five-degree minimum average temperature.
What to Consider When Planting in Zone 6
Each USDA hardiness zone has 10 degrees of minimum average temperature difference. For instance, Zone 11’s minimum temperature rarely falls below 40°F, giving it a nearly year-round growing season. By comparison, mid-April is outdoor planting time for Zone 6, and low temperatures can range from -10°F to 0°F.
It’s pertinent that any permanent plantings you choose to plant in Zone 6 are hardy to that zone. Hardiness means that they can withstand the minimum average temperature well enough to thrive each year. Summertime in any zone works well for annual plants and flowers such as Zinnias and Coleus, but perennials, shrubs and trees need to withstand the minimum temperature in your planting zone.
It’s also imperative to understand your soil conditions before planting. Soil can vary greatly from area to area, and your soil’s health will directly affect your plants’ health. Consider things like composting, soil additives, and soil conditioners–these will give your new plants and shrubs a great head start as they acclimate to your landscape.
In addition, if you have broad shade patches or areas near running water, lakes, or ponds, you’ll want to consider how those things will affect your soil, as well. Areas with no shade can become extremely dry, so be sure to plant with that in mind too. In general, observe your property so you can make informed planting decisions.

These dates should be used as a baseline, as weather conditions can change quickly. Be sure to check your weather forecasts to determine the best time to plant in your area each year.
