Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

It's a good idea to estimate when you can plant erysimum by checking out the USDA zone info for Zone 13a.

Planting Calendar for Erysimum

Frost tolerance for erysimum:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

You can plant erysimum a little earlier in the year because they are moderately cold tolerant.

The earliest that you can plant erysimum in Zone 13a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant erysimum and expect a good harvest is probably November. If you wait any later than that and your erysimum may not have a chance to grow to maturity. Starting your erysimum indoors is a great way to get them started a few weeks earlier.
