Is there one tomato planting window for all of Texas?

No. The calendar shows a Central Texas reference. Confirm local frost risk, planting-zone temperature, cultivar and market timing in your production district.

Does a green heatmap tile mean tomatoes should be planted?

It only means the historical monthly mean meets the sourced minimum and no mean frost days are recorded. Check actual soil, forecast, crop calendar, water and the remaining season before planting.

Does this guide cover processing tomatoes?

It covers outdoor transplanted fresh-market production. Processing contracts, plant types, field layout and mechanical harvest require a different production plan.

Why are establishment and fruit-set temperatures separate?

The soil-temperature reference concerns transplant establishment. The heat reference concerns flowering and pollination in air. They measure different conditions and are not interchangeable.

Should every tomato lot use the same storage temperature?

No. Maturity, cultivar, duration and buyer requirements determine the handling plan. Tomatoes can suffer chilling injury when held too cold for too long.

Growing tomatoes in Texas

Plan Texas fresh-market tomato production around a buyer, reliable irrigation and a harvest crew. Frost limits establishment, while summer heat can interrupt fruit set. A spring crop and a fall trial need separate field and marketing plans.

Scope: Outdoor, transplanted fresh-market tomatoes. Central Texas dates are a named reference, not a statewide schedule. Processing crops and controlled greenhouse production need different systems. Updated 2026-10-05.

Planting climate heatmap

Reference period: 1996-01-01 to 2025-12-31. ERA5-Land monthly mean soil temperature at 0–7 cm, air temperature and frost days at the regional reference point (31.5, -99). Select a month to inspect its historical conditions.

Penn State’s commercial transplant reference requires soil at 3 inches (7.6 cm) to reach 60°F (15.6°C). Historical 0–7 cm means are a shallow proxy. This screen checks that minimum and frost context only. No upper planting-soil threshold is inferred from air-temperature effects on flowering.⁴

Muted green: the temperature meets the sourced minimum and no mean frost days recorded. Neutral tiles name the temperature or frost constraint. Gray: missing data. No upper soil-temperature limit is assessed. This screen does not assess the full growing season, field drainage or crop maturity.

March: Frost caution

The monthly mean meets the lower temperature criterion, but frost occurs in the historical record. Check the actual frost forecast and crop protection.

Mean topsoil temperature: 16.7°C
Mean air temperature: 16.6°C
Mean frost days per month: 1.2 days

These are monthly means at one reference location. They describe seasonal field conditions, not crop maturity, actual seed-zone conditions, frost forecasts or a planting recommendation. Harvest bands follow the crop-specific production sources above.

Choose the market and field system

Agree the sales plan: Confirm fruit type, size, maturity stage, packaging and delivery frequency with the buyer before ordering plants. Wholesale volume requires sizing, grading and enough packing capacity to move the crop.³
Budget the actual operation: Include transplants, bed preparation, supports, mulch, irrigation, repeated picking, grading losses and transport. The small-acreage source identifies high production risk and variable prices. Its historical dollar figures are not a current return forecast.³

Establish clean transplants on prepared beds

From nursery order to field establishment^3,4,7

Choose maturity and resistance: Match cultivar maturity and resistance to field history and the buyer. The Texas disease handbook favors resistant cultivars for soilborne wilt problems. Resistance does not remove the need for clean stock and rotation.⁵
Inspect incoming trays: Check leaves and stems for spotting, wilting and cankers. Separate suspect lots and obtain a diagnosis before field planting. Bacterial disease can spread through nursery trays and infected plants will not become healthy after transplanting.⁷
Prepare water and soil first: Have irrigation working before plants arrive. Soil-test the field and base amendments and fertilizer on the results. Avoid poorly drained areas and establish only after frost danger has passed.^1,3,4

Set spacing and support for field access

Overhead single-row tomato layout with 61 cm between adjacent plant centers and 1.83 m between adjacent bed centerlines — Texas commercial layout example: 61 cm (24 in) between adjacent plant centers, within the cited 18–24 in range, and 1.83 m (6 ft) between bed centerlines. Source 1. Schematic, not to scale. Illustration.

Use the commercial bed reference: The Texas guide places plants 18–24 inches apart on 6-foot raised beds. For a single-row layout, label the 6 feet as the repeated bed center interval, not a clear gap between bed edges. Adjust layout for equipment and cultivar.¹
Install a workable support system: Stakes with string weaving are a commercial option. Support keeps fruit off soil and makes repeat picking easier. Keep access for scouting, support work and harvesting.^1,3

Manage irrigation, nutrition and summer heat

Maintain even moisture: Use drip irrigation and field moisture checks to avoid dry-to-wet swings. Excess water can worsen cracking. Schedule water for soil, weather and crop demand rather than copying a fixed daily amount.^4,5
Keep fertility tied to tests: Use the soil test to set a nutrient plan and review plant response as fruit develops. Excess nitrogen and moisture fluctuations can contribute to blossom-end rot. Diagnose the cause before adding another input.^4,5
Watch flowering separately from establishment: AgriLife associates air temperatures above 92°F (33.3°C) with bloom drop and poor fruit set. Record flowering, heat episodes and saleable yield when evaluating a summer or fall crop.¹

Scout disease and protect saleable fruit

Use field history: Plan rotation around tomato and related crop disease history. Clean transplants, drainage and resistant cultivars address different risks. Inspect lower leaves, stems and fruit during scouting and record where symptoms begin.^5,7
Respond to moisture and symptoms: Wet weather favors several leaf and fruit diseases. Soil contact also increases some fruit-rot risks. Diagnose suspicious symptoms and choose current crop-labeled controls with local extension advice.⁵

Pick to the buyer grade and control handling

Harvest and dispatch checks^3,6

1
Inspect maturity
Match the fruit to the intended buyer grade.
2
Grade gently
Separate defects and avoid crushing fruit.
3
Handle by stage
Use temperature appropriate to maturity and duration.
4
Dispatch
Retain lot identity through packing and delivery.

Plan repeat picking: Agree maturity specifications and inspect readiness repeatedly. Picking, grading and dispatch can become the limiting operations as volume increases. Provide clean containers and protect fruit from compression.^3,6
Set temperature by maturity: UC Davis gives 12.5–15°C for mature-green fruit, 10–12.5°C for light-red fruit and 7–10°C for firm-ripe fruit held only 3–5 days. Ripening uses 18–21°C and 90–95% relative humidity. Do not use one refrigeration setting for every lot.⁶
Keep a lot record: Record harvest date, cultivar, maturity, defects, storage temperature and dispatch. Review rejected or downgraded fruit with the buyer to identify field and handling losses.^3,6
