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.

A common way of determining when it's possible to plant digitalis is to refer to the USDA zone info for Hubbard.

Planting Calendar for Digitalis

Frost tolerance for digitalis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since digitalis are moderately cold tolerant you can plant them just a bit earlier in the year than other frost tender plants.

The earliest that you can plant digitalis in Hubbard is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant digitalis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your digitalis may not have a chance to grow to maturity. Starting your digitalis indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is April 15 in Hubbard. It might get as low as -10°F during the coldest months of winter.

Since the USDA zone info for Hubbard is not always accurate the actual date of last frost is different every year. Half of the time in Hubbard there is a last frost after April 15 so be sure to be ready to cover your digitalis in the event of one of those late frosts.
