One of the best tools that you have as gardeners to help us estimate 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.

The USDA zone info for Cambridge should be looked at 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 very little cold which means that you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant gerbera in Cambridge is April. However, you really should wait until May 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. Starting your gerbera indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on May 15 in Cambridge. It might get as low as -30°F during the coldest months of winter.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Cambridge and it can change quite a bit from year to year. Half of the time in Cambridge you get a frost after May 15 so make sure that you are prepared to protect your gerbera if you have one of those late frosts.
