Before planting it is a good idea to find your USDA Zone info to figure out 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.

You should be able to estimate when it's possible to plant garden orache by referring to the USDA zone info for Houston.

Planting Calendar for Garden Orache

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

Since garden orache do well in moderate cold you can plant them a little earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant garden orache in Houston 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 garden orache and expect a good harvest is probably October. You probably don't want to wait any later than that or else your garden orache may not have a chance to fully mature. Starting your garden orache indoors is a great way to get them started a little bit earlier.

Last Frost Date

The average date of last frost is February 15 in Houston. In the coldest months of winter you should expect an average low temperature of 20°F.

Always keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Houston and it will vary from year to year. Half of the time in Houston you get surprised by a frost after February 15 so be sure to be ready to cover your garden orache in the event of a late frost.
