Okra goes in after the last 32°F freeze has passed and the soil has warmed, not before. Texas has no single date for that. At the Gulf end, the reference point for this page, freeze odds fade between February 4 and March 1, so seed goes in after that window closes. Farther north and at altitude the calendar slides later, and this page does not have the figures to say by how much.
The short answer for Texas
Plant okra in Texas after the last spring freeze and once the soil feels warm to your hand. At the Houston reference station used here, that means sowing after the February 4 to March 1 window closes. That is a Gulf Coast answer, and it should not be copied onto a Panhandle garden.
What the frost dates are a probability of
Those dates are not a promise. They come from the NOAA NCEI 1991-2020 Climate Normals for station USW00012960 (Houston Intercontinental, known as IAH), and they describe the chance of a 32°F freeze, banded between 30 and 70 percent. Inside that band, a freeze is a real possibility rather than a rarity. Put tender seedlings out on February 4 and you are betting against odds that have not turned yet. Wait until the band ends and most of that gamble is gone.
| Event | Window at IAH | What it measures |
|---|---|---|
| Last spring 32°F freeze | February 4 to March 1 | 30-70% freeze probability band |
| First fall 32°F freeze | December 1 to December 19 | 30-70% freeze probability band |
Why the long season changes the plan
Count from the end of the spring band to the start of the fall one and you get roughly nine months of freeze-free ground. Add 102.4 days a year at or above 90°F, and you have a place where okra’s love of heat is an asset. The practical move is to take the days-to-harvest number on your seed packet and count backward from the fall window. That tells you how late a sowing can still pay off.
Even inside Houston the dates are not uniform. Hobby airport runs about two weeks milder than IAH, so a garden near the Gulf can reasonably start earlier than one inland. For a full growing guide, see Growing Okra in Texas, and for choosing what to sow once the window opens, The Best Okra to Grow in Texas.
What will not work here
Sowing in the February band because the afternoons feel mild. A warm week in the middle of that window says nothing about the next cold snap, and okra seed in cold, wet ground tends to sit and rot rather than sprout. The freeze odds are still between 30 and 70 percent. Patience costs a few weeks, and a failed first sowing costs the same few weeks plus the seed.
Copying the Houston calendar north is the second failure, and probably the most common. These numbers are the mild Gulf end of a state whose hardiness zones run from 6a to 10a. A gardener in the Panhandle who sows on a Houston date is working from the wrong map. Freezes there come much earlier in fall and linger much later in spring.
Then there is weekly watering in midsummer. Houston’s summer rain looks generous on paper, about 14.6 inches across June, July and August, out of 51.8 for the year. But July is the driest of the three at 3.77 inches (June gets 6.0, August 4.84), and it lands in the stretch when okra is putting out pods and drinking hardest. With 102.4 days a year reaching 90°F, evaporation takes a lot of that back. Rain that arrives as one thunderstorm mostly runs off rather than soaking in.
Soil decides how much of it you keep. Sand lets a rainfall through within the day, while clay can hold it for a week, so the same July can mean very different watering schedules on two lots a few miles apart. This page does not know your soil. A straight-sided can set out in the garden will tell you what actually fell, which beats any normal.
Last, tight spacing. Humid summers keep leaf surfaces wet, and crowded rows hold that moisture in. Plant at the spacing on the seed packet, or lean wider if your garden sits in a low, still corner where air barely moves. Normals describe what a region can usually expect over 1991-2020. They are not a forecast for this July, and a wet year will punish a crowded row.
What changes across Texas
There is no single Texas answer. The USDA Plant Hardiness Zone Map (2023 edition, built on 1991-2020 normals) places the state anywhere from 6a to 10a. That span covers a very wide range of winter cold, from the Gulf end where these frost dates were measured to colder country far from the coast.
One caution about reading that map. A hardiness zone rests on a single variable, the average annual extreme minimum temperature. It tells you how cold the worst night of winter gets. Okra is grown as a summer annual and dies at the first hard freeze regardless of zone, so the zone is a rough indicator of where you sit on the cold-to-mild spectrum, not a sowing date. Frost dates and local soil warmth do the real work.
If you garden in the north of the state or at altitude, shift three things from the Houston picture. Sow later, once the spring freeze risk has actually passed where you live. Expect the fall freeze to arrive well before December. And lean toward okra types that mature faster, since your usable season is shorter. The varieties page covers how to choose by type.
Where you fall on that spread is something to look up, not guess. The USDA map lets you enter a ZIP code and read your own zone. This page will not tell you which one you are in, and the Houston figures above are only the mild end of the range.
Where to check this for your own county
Your state extension service is the next stop. Texas A&M AgriLife Extension runs the land-grant university’s outreach in Texas and keeps offices at the county level. That is where the numbers stop being averages for a region and start being advice for where you live.
Look for two things. First, a local planting calendar for warm-season vegetables, which usually names the sowing window for your area rather than the whole state. Second, any variety trials run in your county, since a type that performs on the Gulf Coast may not hold up in drier, cooler or higher country. If the county office has a staff member or Master Gardener volunteer line, a short call about okra timing is worth making.
A county recommendation beats a state one, and this page is the state one. It is built on a single reference station in Houston, and it exists to show you how the logic works: freeze probabilities, heat load, rainfall and soil. When the county calendar disagrees with the dates here, trust the county. It was written by people who know the local ground.
Checking this against your own garden
Every date on this page gives way to what you see in your own beds. Three observations are worth more than the calendar, and none needs equipment.
- Soil warmth by feel. Push your hand a few inches into the bed in the morning. If it feels cool and clammy, okra seed will sulk. If it feels neutral or warm, the ground is ready. A bed against a south-facing wall will warm weeks ahead of one in shade, and that gap is your microclimate talking.
- The first true leaves. The first pair that appears after the seed leaves tells you how the seedling is coping. Steady growth means the soil and air suit it. A stall, with leaves yellowing or curling, usually means a cold night or soggy ground you did not know about.
- The first flowers. When the first blooms open, you are close to the first pods. Compare the date to a neighbor’s, or to your own last year. If yours open days earlier, your site runs warmer than the regional picture suggests.
Write the dates down each year. After two or three seasons, those notes will outrank any normal, including the ones here.
Common questions
Can I plant okra in Texas in February?
At the Houston reference station, February 4 to March 1 is the band where a 32°F freeze still carries a 30 to 70 percent probability. Sowing inside it is a gamble. Farther north, the risk lasts longer.
How late can I plant okra in Texas?
This page does not have a single cutoff date. At the Houston reference, the first fall freeze falls between December 1 and December 19. Check the days to harvest on your seed packet and count backward from your local fall freeze date.
Does okra need a lot of water in a Texas summer?
Summer rainfall at the Houston reference is about 14.6 inches, with July the driest month at 3.77 inches. With 102.4 days a year at or above 90°F, and storms that often run off, rain alone may not cover okra’s needs. Your soil type and a rain gauge in your own garden settle it.
Does my hardiness zone tell me when to plant okra?
No. The USDA zone reflects the average annual extreme minimum temperature, and Texas ranges from 6a to 10a. For timing, use your local last-freeze date and how the soil feels, and check your county’s AgriLife Extension office.
