When can I plant Salsify in Zone 5a

One of the best tools that we have as gardeners to help us figure out our 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 our area.

The earliest that you can plant salsify in Zone 5a is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant salsify and expect a good harvest is probably August. Any later than that and your salsify may not have a chance to grow to maturity. If you are starting your salsify indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Zone 5a. It might get as low as -20°F during the coldest months of winter.

It's important to remember that our actual date of last frost is an average because it is based on the USDA zone info for Zone 5a and it will vary from year to year. Half of the time in Zone 5a it frosts late in the year after April 15 so make sure that you are prepared to protect your salsify if we have a late frost.
