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

In Katy you can figure out when you can plant pansies by reviewing the USDA zone info.

Planting Calendar for Pansies

When to plant:	Up to 7 weeks before last frost.

Pansies are very cold tolerant which means that you can plant them much earlier than other plants that might not handle the cold.

The earliest that you can plant pansies in Katy 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 pansies and expect a good harvest is probably October. Any later than that and your pansies may not have a chance to fully mature. If you are starting your pansies indoors then you might be able to get away with starting them a little bit earlier.
