Questions gardeners ask
When is the last frost in Texas?
The statewide average last spring frost is around March 15. There is still roughly a one-in-two chance of frost on that date, so for tender plants a safer date is about two weeks later, around March 29. Texas covers a wide range of elevations and climates, so check your own ZIP code.
When is the first frost in Texas?
The average first fall frost is around November 15. Frost-tender crops such as tomatoes, peppers, beans and squash should be harvested or covered before then; an early frost two weeks sooner, around November 1, happens in roughly one year in ten.
How long is the growing season in Texas?
About 245 frost-free days on average between the last spring frost and the first fall frost. That is a long season, with room for a spring and a fall garden and long-season crops.
When can I plant tomatoes outside in Texas?
Plant tomato transplants outdoors between March 15 – April 1, once nights stay above about 50°F. Start seeds indoors six to eight weeks earlier.
Is it safe to plant on the average last frost date?
For hardy crops such as peas, spinach, onions and cabbage, yes - they handle a light frost. For tender crops, no: the average date still carries about a 50% chance of a later frost, so wait one to two weeks or keep row cover ready.
