Texas has several growing climates. While some are warm with few cold variations, other climates are warm with longer frost and cold periods. Texas often is divided into areas of East, South, West, North and Central Texas. These areas often refer to the varying climates of the state. Knowledge of the planting area's climate variation, along with general knowledge of the tree's requirements, will assist the Texas gardener in growing trees in the area.
Plant a tree that will thrive in the selected climate zone. Plant in a location that is free of overhead and underground obstructions, such as power lines and septic tanks.
Plant the tree in a well-drained location that receives at least eight to 10 hours of partially shaded to full sunlight each day. Pick the sun-exposure levels based on the tree's individual requirements.
Irrigate the tree deeply and infrequently, about once a week during the growing season. Adjust the levels accordingly during periods of heavy rainfall and hot, drought periods. Provide the tree with irrigation levels based on the diameter of the trunk, at a rate of 10 gallons of water for every inch of trunk diameter.
Feed the tree throughout the growing season from early spring through late fall with a well-balanced, slow release fertilizer such as a 20-20-20 or 40-40-40 combination. Follow the label instructions. Distribute the fertilizer evenly under the canopy of the tree. Keep the fertilizer at least 12 inches from the base of the trunk to prevent root burn. Water the fertilizer thoroughly into the soil.
Apply a 2- to 4-inch layer of mulch around the tree to protect the soil's moisture levels and reduce the potential for weed invasion.
Prune the trees during their dormancy. Remove any dead, dying or wilted areas from the tree with sharp, sterile pruning shears. Make angular cuts on the branches and steps to promote rapid healing. Make flush cuts against the stem to prune foliage.
