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

A common way of figuring out when you can plant mustard greens is to use the USDA zone info for Zone 13a.

Planting Calendar for Mustard greens

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

You can plant mustard greens a little earlier in the year because they are one of those plants that can tolerate a little bit of cold weather.

The earliest that you can plant mustard greens 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 mustard greens and expect a good harvest is probably November. Any later than that and your mustard greens may not have a chance to grow to maturity. Starting your mustard greens indoors is a great way to get them started a few weeks earlier.
