Timing plays a pivotal role in cultivation. If you start planting when the weather is too hot or cold, your vegetables may not survive, let alone thrive.
As someone who lives in the Lone Star State, you’ve probably asked yourself, “when to plant a vegetable garden in Texas?”
Generally, the growing season in Texas spans January 1st to October 15th, but these dates can vary. For example, the beginning of the planting period may not start until mid-April, and its end can fall between October 15th and December 31st. Read below for more info.

When to Start Planting in Texas?
The best time to plant a spring garden in Texas is when the last frost date of the season ends. As stated above, it may fall within January to April.
To find this date for your location, you can enter your zip code on almanac.com. But for quick reference, here are the last spring frost days for some regions in Texas:
- Austin – March 18
- Brownsville – January 24
- Dallas – March 9
- Fort Worth – March 12
- Georgetown – March 15
- Houston – February 18
- Huntsville – March 10
- Irving – March 9
- Mansfield – March 16
- Lancaster – March 20
- San Antonio – March 5
- Temple – March 22
- Texas City – January 31
- Victoria – February 27
- Note that the above are only estimates, so it’s best to check the weather forecasts for your location. If the temperature is 32 degrees Fahrenheit or under, don’t start gardening just yet.
Plus, to be safe, delay your Texas planting schedule by two weeks. That way, if a spring frost comes later than predicted, it won’t destroy your vegetables.
2. Fall and winter
Fall/winter is the second planting season in Texas. To grow foods successfully in this period, you need to sow seeds in July (at the earliest) or October (at the latest).
Check out the days of the first fall or winter frost for some Texas regions below. Your vegetables should finish maturing and get harvested by then.
At the same time, look up how long it takes your plants to grow and sow seeds accordingly. For example, radishes can mature in a month, so if your first autumn frost is on November 18, you need to plant these root veggies on October 18 at the latest.
Similar to the spring schedule, you can find the fall ice dates for your locality on almanac.com.

- Brownsville – December 29
- Dallas – November 20

- It’s possible to start the garden planting calendar earlier by growing vegetables indoors and transplanting them outdoors 10 days to two weeks after the last spring frost date.
For instance, you can put broccoli, spinach, and tomatoes into small pots at the end of December or early January. Once the temperature becomes warm enough, you can transfer them into garden beds.
- Note that the soil and surrounding air must be 60 to 70 degrees Fahrenheit. Otherwise, the plants may die, whether they’re inside your home or outside.
- Some flora, such as beans, watermelons, and sweet corn, are very difficult to transplant, as you cannot discard their containers. For these species, it may be better to follow the dates above and plant them directly into the ground outdoors.
