The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The earliest that you can plant geum in Zone 6b should be figured out by checking out the USDA zone info.

Planting Calendar for Geum

Frost tolerance for geum:	Tolerant of a very small amount of frost.

Geum do well in very little cold which means that you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant geum in Zone 6b 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. Any later than that and your geum may not have a chance to fully mature. If you are starting your geum indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 6b the average date of last frost happens on April 15. It might get as low as -5°F during the coldest months of winter.

Since the USDA zone info for Zone 6b is not always accurate the actual date of last frost will vary from year to year. Half of the time in Zone 6b last frost occurs after April 15 so always be ready to cover your geum if you have one of those late frosts.
