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.

You can determine when you can plant digitalis in Oregon by referring to the USDA zone info.

Planting Calendar for Digitalis

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

Digitalis do well in some cold which tells us that you can plant them a bit earlier in the year than more sensitive plants.

The earliest that you can plant digitalis in Oregon 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. If you wait any later than that and your digitalis may not have a chance to grow to maturity. Starting your digitalis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

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

Keep in mind that USDA zone info for Oregon is just an average and the actual date of last frost is different every year. Half of the time in Oregon there is a last frost after April 15 so always be ready to protect your digitalis in the event of a late frost.
