Southeast Texas features the long, hot and humid summers of USDA Growing Zone 9, with winter temperatures that rarely drop under 20 to 30 degrees Fahrenheit. These conditions offer ideal weather for almost every fruit tree and are ideal for some of the more specialized citrus trees.
Southeast Texas is part of the Sunbelt, which runs from Southern California, through south Texas and into Florida. This area offers extremely humid subtropical summers, where sensitive fruit trees thrive. According to Aggie Horticulture, subtropical trees like oranges and grapefruits are particularly popular in this region of Texas.
Stone Fruit Trees
Stone fruit trees like peaches, plums and cherries are hardier to cold than citrus fruits and grow well throughout the nation. Aggie Horticulture's East Texas Gardening recommends peaches, nectarines, plums and apricots for this region of Texas.
Seed Fruit Trees
Seed fruit trees are equally hardy and enjoy the warm summers of south Texas for ripening into large, juicy fruit. Plant apples, pears, persimmons and Asian pears in this region for fruit-growing success.
Gardeners should plant new fruit trees after the last frost in their area, which may fall as early as late March in Southeast Texas. Fruit trees require sites that get full sun for eight hours a day and complete drainage. Ideal growing foundations for fruit trees include both quick-draining soil and organic compost.
