Louisiana's subtropical climate provides good conditions for citrus trees, though gardeners must be wary of frost. Growers in northern and central Louisiana should plant only proven cold-hardy citrus (like Meyer lemon, satsuma and kumquat), while growers in southern Louisiana can grow any type of citrus. Plant citrus in Louisiana after frost danger passes in the spring.
Plant citrus tree saplings in a site that offers well-draining soil, full sun and enough room to mature. Four Winds Growers recommends a combination of protection from wind and southern exposure. Citrus trees grow well in a variety of soils, so you don't need to test the pH in your native soil.
Dig a hole for your citrus tree equally deep and twice as wide as the container holding your sapling. Use a shovel. Remove weeds, rocks or roots from the soil so the tree's roots won't have to compete.
Remove your container citrus from its pot. Massage the root ball with your fingers to break it apart. Unwind and untangle any circled or tangled roots. If you don't, the young tree can choke from lack of nutrients.
Place the citrus tree in the prepared hole and check to ensure the tree is vertically straight. The tree should rest at the same level as it sat in the container. Backfill the hole with soil but do not compress the soil.
Water your newly planted citrus tree until the ground becomes saturated with water and the soil fills in around the trunk.
Pound two wooden stakes into the ground 12 inches from the tree's trunk, using a hammer. Tie ropes around the tree trunk and to the stakes so the young tree has support while growing. Don't tie the ropes too tight or they'll cut into the tree as its limbs grow.
