Citrus trees in east Texas have a better chance of winter survival near coastal waters. Regardless of species for citrus trees, all varieties of citrus must be of Texas propagation origin. It is illegal to import any portion of a citrus plant in any form from other states or locations, says Texas A&M professor Julian W. Sauls. With proper care a citrus tree planted in east Texas will bear fruit for the home orchard. Special care must be exercised when planting the nursery grown container plant.
Dig the transplant hole slightly larger than the container of the citrus tree seedling. Loosen the soil inside the hole with a shovel.
Remove the seedling from the container. Gently wash away with a garden hose approximately 1-inch of the soil-less medium that surrounds the citrus tree rootball.
Set the citrus tree seedling into the transplant hole. Keep the tree about 1 inch higher in the transplant hole than it was in its nursery container. Never set the top of the rootball below the ground level of the transplant hole, as this will cause the roots to stay wet and create rot.
Backfill with native soil halfway up around the rootball of the seedling.
Water the seedling to settle the backfill around the rootball.
Continue to backfill the soil around the rootball. Add approximately 1 inch of soil over the top of the rootball to seal the growing medium from the air.
Build a soil watering ring around the new seedling from excess soil that is 24 inches in diameter and approximately 3 inches wide and high.
Fill the watering ring with water. Allow the water to soak into the soil. Add more soil and re-water the if holes form in the soil. Water the citrus tree every few days for the first three weeks, then every seven days to 10 days thereafter for the next two months.
Cut a heavy-duty aluminum foil sheet that is approximately 8 inches wide and 18 inches long. Wrap the foil from top to bottom once around the trunk. Crimp the two edges together.
Feed the new citrus tree after new growth occurs with 1/4 cup of 21-0-0 three to four times during the first year.
