One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The best time to plant geum in Zone 6a can be determined by reviewing the USDA zone info.

Planting Calendar for Geum

Frost tolerance for geum:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Geum can survive in some cold which means that you can plant them just a tiny bit earlier in the year than other frost tender plants.

The earliest that you can plant geum in Zone 6a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant geum and expect a good harvest is probably August. You probably don't want to wait any later than that or else your geum may not have a chance to fully mature. You can get started a little bit earlier by starting your geum indoors.

Last Frost Date

On average the last frost has passed is on April 15 in Zone 6a. You can expect an average low temperature of -10°F in the coldest months of winter.
