One of the first steps you take when you are figuring out your gardening schedule is find your 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.

In Clay you can estimate when it's the best time to plant stoneseed by using the USDA zone info.

Planting Calendar for Stoneseed

Since stoneseed do not do well in cold weather you really should wait until after the last frost has passed before you can plant them.

The earliest that you can plant stoneseed in Clay is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant stoneseed and expect a good harvest is probably August. Any later than that and your stoneseed may not have a chance to grow to maturity. Starting your stoneseed indoors is a great way to get them started a little bit earlier.
