One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when it's possible to plant cucumbers is to examine the USDA zone info for Houston.

The last month that you can plant cucumbers and expect a good harvest is probably September. Any later than that and your cucumbers may not have a chance to grow to maturity. Starting your cucumbers indoors is a great way to get them started a couple of weeks earlier.
