One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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.

By reviewing the USDA zone info for Zone 2b it's a good idea to estimate when it's possible to plant gerbera.

Planting Calendar for Gerbera

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

Gerbera do well in some cold which tells us that you can plant them slightly earlier in the year than other frost tender plants.

The earliest that you can plant gerbera in Zone 2b is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant gerbera and expect a good harvest is probably August. You probably don't want to wait any later than that or else your gerbera may not have a chance to really do well. If you are starting your gerbera indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Zone 2b the average date of last frost happens on May 15. You can expect an average low temperature of -45°F in the coldest months of winter.

Remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 2b and it changes from year to year. Half of the time in Zone 2b it frosts late in the year after May 15 so be sure to be ready to cover your gerbera if you have a surprise late frost.
