The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

It's a good idea to estimate when it's the best time to plant stocks by referring to the USDA zone info for Katy.

Planting Calendar for Stocks

Frost tolerance for stocks:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Stocks do well in mild cold which means that you can plant them just a tiny bit earlier in the year than other frost tender plants.

The earliest that you can plant stocks in Katy is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant stocks and expect a good harvest is probably September. You probably don't want to wait any later than that or else your stocks may not have a chance to really do well. Starting your stocks 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 Katy. You can expect an average low temperature of 20°F in the coldest months of winter.
