Grant: Last chance for tomato planting in East Texas

If you haven’t planted beans, corn, cucumbers, peppers, squash, and tomatoes, you’d better get it done ASAP, as spring in East Texas can last anywhere from 30 minutes to 30 days.
Once it gets hot, it’s not only harder to get transplants established but all tomatoes stop setting fruit.
Tomatoes are planted from transplants after all danger of frost. Tomato plants can’t tolerate frost or freeze and thrive with mild temperatures. Tomatoes don’t set fruit in the heat of summer (above 92 degrees) which leaves only a small window of opportunity to form fruit. This makes planting time critical. If you plant too soon (before March 15), frost will often kill them. If you plant too late (after April 15) you severely reduce your production.
The ideal transplant is 6 to 8 inches tall, dark green, and has 6-8 healthy leaves. Avoid those that are yellow-green, purple-green, or spindly and tall. Once stunted they will not produce much. To avoid unexpected late frosts, many gardeners have buckets or row cover ready for protecting plants.
Often summer heat, drought, and insects kill spring planted tomatoes in Texas. That is normal.
Productive tomato varieties for Texas are Better Boy, BHN 589, Bobcat, Celebrity (the best for beginners), Florida 91, Harris-Moran 8849, Phoenix, Red Deuce, Red Snapper, Sunbright, Tycoon, and Valley Cat. Unfortunately, all but Celebrity and Better Boy are difficult to obtain. Most cherry varieties produce well, and most patio types don’t. Unfortunately, most heirloom tomatoes and other indeterminate types are not productive in Texas.
Tomatoes require at least 8 hours of direct sunlight each day for maximum yields. Tomatoes do best in rich, loamy soils. Due to root infecting nematodes (typical of sandy soils), it is best to avoid areas where this has been a problem the previous year. Choose nematode resistant varieties such as Celebrity and Better Boy in this case. It is ideal to till in several inches of compost and incorporate two pounds of a complete lawn fertilizer (15-5-10, etc.) per 100 square foot of bed or every 35 feet of row before planting. In small plantings incorporate two teaspoons per square foot or foot of row. Organic fertilizers work well but because they are lower in nutrients you must use more for the same results. The ideal soil pH for growing tomatoes is 6.0-7.0.
Tomato transplants should be planted in well-cultivated soil. Dig holes twice as wide and at least as deep as the existing pots they grew in. Tomatoes can form roots along their stem so tall plants should have the lower several inches of their stems buried beneath the soil. By planting them deeper you produce a stronger plant with more roots. Strip any foliage off the lower stem that is to be beneath the ground and place into the hole. Gently firm the soil around them. Water thoroughly with a water-soluble plant food such as Miracle Grow at the labeled rate.
