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

In Burnet you can estimate when to plant primroses by looking at the USDA zone info.

Planting Calendar for Primroses

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

Primroses can survive in quite a bit of cold which means that you can plant them much earlier in the year than other frost tender plants.

The earliest that you can plant primroses in Burnet 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. Any later than that and your primroses may not have a chance to fully mature. Starting your primroses indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Burnet the average date of last frost happens on March 15. You can expect an average low temperature of 10°F in the coldest months of winter.

Since the USDA zone info for Burnet is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Burnet last frost occurs after March 15 so always be ready to protect your primroses in the event of one of those late frosts.
