Gardeners living in Florida have three different climatic regions to plant and grow fruit trees. Northern regions are a warm temperate zone, central regions of the state are a subtropical zone and the southern portions are in the subtropical/tropical zone. Where you live will determine which fruit tree will grow best in your area. The species of fruit tree will determine the care that is required to maintain a healthy tree. Many fruit trees grown in the southern sections of the state, will not tolerate the cold temperatures experienced in the northern regions.
Grow your fruit tree in an area that is large enough for it to reach full size and is situated in full sun. Fruit trees will grow best in areas where they are not crowded and receive proper air circulation. Most varieties of fruit trees require a certain amount of sunshine during the day for proper growth and production of fruit.
Grow your fruit tree in soil that is rich in organic material and drains very well for best growth and fruit production. Florida soil is sandy loam and requires amending with compost, peat or manure.
Water your fruit tree regularly, according to the variety's specific requirements. Fruit trees such as avocados will have lower watering needs than a fruit tree such as a nectarine. All varieties of fruit trees in all areas of the state will require more water during seasons where the weather is extremely hot and dry. Always water deeply.
Fertilize your fruit tree regularly according to the variety's requirements. Fruit trees such as bananas will require feeding more often than a fruit tree such as an avocado. Use a high quality fertilizer and water in well, once applied. Do not allow the fertilizer to mound up around the fruit tree's trunk or it can become burned. Apply a bag of compost on top of the soil in spring and water in well.
Prune the fruit tree to remove dead wood or to control its size and shape. Some fruit trees such as citrus require little to no pruning at all. Trees such as peaches and nectarines require limbs pruned from their centers to keep the area open. Allow one or two main branches in the center to remain and trim off any fresh center shoots that will crowd the area. Wait until spring to prune off any frost damage.
Protect tropical and subtropical fruit trees from frosts and freezes. Fruit trees grown in this region are not accustom to freezing temperatures and can be damaged. Wrap the tree in a blanket and situate a light under the cover or hang Christmas lights on the tree to keep it warm.
