Limes are popular citrus fruit trees grown in many tropical areas, including warm temperate regions of South Florida. Two types of lime trees are typically grown in South Florida: Mexican or Key limes, which produce light green, seedy, acidic round fruit approximately 1 to 2 inches in diameter; and Tahiti or Persian limes, which produce dark green, seedless, oval-shaped fruit that are larger and less acidic than Mexican or Key Limes. With some care and preparation, these types of lime trees can be successfully planted and grown in outdoor areas in Florida where freezes do not generally occur.
In fall or early spring, select a planting site has good air circulation, drainage and receives the maximum amount of sunlight during the day.
Prepare the site by pulling out the weeds, and then remove any remaining debris with a garden rake. If a tree was previously planted on the same site, remove all roots and remains of the old tree to prevent the spread of insects or disease to the new tree transplant.
Purchase a lime tree from a local nursery or home and garden center.
Remove the lime tree from its container, and inspect the roots. If the tree's roots appear to be pot-bound, or growing in a large horizontal mass, make several vertical cuts through the roots with a sharp, clean knife.
Place root-ball of the tree in a large bucket. Position the tree upright and fill bucket with water to soak the roots before planting.
Dig a hole approximately twice the width and depth of the root-ball. Place the tree in the center and carefully loosen and spread the roots out in the hole.
Backfill with dirt approximately half way up the hole and pat soil down to remove air pockets. Water well and then permit the dirt to settle. Adjust the tree so it sets slightly above its original planting depth, backfill the rest of the hole with soil, pat down and water. As it grows, your lime tree will require at least 1 inch of water each week through rain or irrigation.
