Peaches (Prunus persica) are widely grown in Texas, although the varying climate from the Gulf Coast and South Texas to the continental weather of North Texas affects appropriate varieties. Texas A&M University has identified numerous cultivars good for growing in various parts of the state.
Sun and Soil
Peaches grow in U.S. Department of Agriculture plant hardiness zones 4 through 8, but most varieties do especially well in zones 7 and 8. They need lots of sun and well-draining soil. The best soil is 18- to 24-inch-deep sandy loam on top of well-draining red clay. Blue, gray or mottled clay typically drains poorly. Peaches grow poorly in salty soil. A soil pH between 6.5 and 7 is ideal.

Cold flows downhill. To protect your plants from cold, plant your tree on a slope or hill if possible.
Winter Chilling Requirements
To break winter dormancy, grown normally in spring and bloom, peaches need a minimum number of winter hours below 45 degrees Fahrenheit. These hours, known as the chilling requirement, vary among peach cultivars. If a tree's chilling requirement is too low, frost may destroy early blooms. If the requirement is too high, a tree may be slow to break dormancy, resulting in low peach yields. The chilling requirement varies different parts of Texas.
Roughly speaking, the chilling requirement for peaches grown in North Texas, including the Dallas-Ft. Worth area, is 900 to 1,000 hours. Going south, the requirement drops to 800, to 700 and then 600 hours at the latitude of Austin in central Texas and to 400 hours at San Antonio and along the Gulf Coast, including Houston. It drops to 200 hours at McAllen and the southern tip of Texas.
Peaches are classified as clings if the flesh clings to the pit and freestones if it does not. Here are some cultivars and their chilling requirements selected at random from 40 cultivars listed by Texas A&M University:
- Flordaprince, (Prunus persica 'Flordaprince') a small cling, 100 hours
- EarliGrande, (Prunus persica 'EarliGrande') a small to medium semicling, 200 hours
- Rio Grande (Prunus persica 'Rio Grande') large freestone, 450 hours
- Tex Royal (Prunus persica 'Tex Royal'), large freestone, 600 hours
- Bicentennial (Prunus persica 'Bicentennial'), small cling, 700 hours
- Fireprince (Prunus persica 'Fireprince'), large freestone, 800 hours
- Surecrop (Prunus persica 'Surecrop'), medium cling, 1,000 hours
You can get by without irrigating your tree if you give it at least 24 feet from other trees so that it has plenty of room for its roots to spread. You will get healthier trees bearing larger peaches if you water them well.
Texas A&M University recommends drip irrigation for peach trees. If you have access to sufficient water, give your new peach tree 7 gallons of water in April and May, 14 gallons in June, 28 gallons in July and August and 21 gallons in September. You may not have to water in autumn if seasonal rains arrive. Give second-year trees 14 gallons of water in April and May, 28 gallons in June, 56 gallons in July and August and 28 gallons in September if autumn rains have not arrived. Give mature, peach-bearing trees 50 gallons of water a day during the spring to autumn growing season.
Give a young peach tree 1 pound of 10-10-10 fertilizer roughly six weeks after you plant it. Scatter the fertilizer 18 inches from the trunk and water well. Apply 3/4 pound of 10-10-10 fertilizer in the spring and the early summer of the second year. Beginning the third year, apply 1 pound of nitrogen each year in early spring when the tree starts to grow. The first number in a fertilizer ratio gives the amount of nitrogen by weight. A 10-pound bag of 10-10-10 fertilizer would yield 1 pound of nitrogen. Avoid fertilizing within two months of the expected first autumn frost.
