Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of making a decision about when it's a good idea to plant salsify is to refer to the USDA zone info for Exeter.

Planting Calendar for Salsify

Frost tolerance for salsify:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since salsify are one of those plants that can tolerate a tiny bit of cold weather you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant salsify in Exeter 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 salsify and expect a good harvest is probably September. You probably don't want to wait any later than that or else your salsify may not have a chance to fully mature. Starting your salsify indoors is a great way to get them started a few weeks earlier.
