One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of figuring out when you can plant primroses is to look at the USDA zone info for Nashville.

Planting Calendar for Primroses

Frost tolerance for primroses:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Primroses are very cold tolerant which tells us that you can get them planted much earlier than other plants that might not handle the cold.

The earliest that you can plant primroses in Nashville 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 primroses and expect a good harvest is probably September. You probably don't want to wait any later than that or else your primroses may not have a chance to really do well. Starting your primroses indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is March 15 in Nashville. It might get as low as 15°F during the coldest months of winter.

It's important to remember that USDA zone info for Nashville may not be accurate from year to year and the actual date of last frost will vary from year to year. Half of the time in Nashville there is a last frost after March 15 so make sure that you are ready to cover your primroses if you have one of those late frosts.
