Keeping your trees healthy
The following is general information based on my experience growing and selling fruit trees for many years as a nurseryman. Your soil conditions, drainage and tree type may require different care. Please note that each section on fruit tree type makes recommendations on the type of fertilizer to use. All fertilizers mentioned are synthetic and I find myself using less and less of them as we convert our growing methods to a more sustainable one with permaculture practices.
Soil fertility
Plants need 19 essential nutrients for healthy plant growth:
carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl), nickel (Ni) Cobalt (Co) and sodium, (Na) .
Of these 19, all except carbon, hydrogen, and oxygen are derived from the soil. When the soil cannot supply the level of nutrients required for adequate growth, traditional horticultural practices call for supplemental fertilizer applications.
Choosing the right method of supplementing the soil is important. You can go organic or synthetic. For more information on this click here.
Choosing and caring for fruit trees.
Many varieties of tropical and sub-tropical fruit trees will grow from North Broward County south to the Florida Keys. Do some research and learn the mature size of the tree and its particular cultural requirements. Remember that fruit trees can be messy around your swimming pools so keep them far away.
When choosing your tree start by looking for a healthy one with a single trunk and good color, not root bound and of course free of insects and diseases. A good size to start with is either a 3 gal or a 7 gal container tree. These trees are a great value for your dollar. These smaller container grown trees will develop stronger root systems. One great advantage also is that you can start training the tree earlier and get better results than with larger more expensive trees.
Most fruit trees can be pruned to a small size for small yards. We at Pepe's Plants have several semi - dwarf trees available that make the task easier. Small trees are easier to harvest, so keep them no taller than you can reach. Many trees can also be grown in containers and treated very much like bonsai trees.
When selecting and planting your fruit tree, consider important factors such as sun, water, salt, and wind.
Tropical fruit trees need to be grown in full sun. That means six to eight hours of sun daily. By providing the tree with plenty of sunlight, it will be healthier and you will have better fruit production and growth. Be sure to prune regularly, when it is not flowering or setting fruit. Keep it healthy by allowing space between branches for air to circulate. Prune away branches that grow into the tree and cross each other creating a mess.
You can plant a tree almost all season but spring and summer are best. Water is vital and the proper amount is just one step towards a healthy tree.
A smart watering schedule really depends on your insight. Consider the season. Summer is our rainy season and winter is very dry. Some trees are dormant in winter and fall and require little water.
Trees grown in plastic containers will require less water depending on how large the container is and how hot and sunny it is. When growing in a terra cotta pot be sure to water more often. With container growing you should use a water probe that will better indicate the moisture level in the pot. They are cheap around $9.99 and work well.
You can place a rain gauge at the base of the tree to keep track of the rain water. Planting trees during the rainy months is smart. Your trees will develop better roots and you conserve water.
Salt intrusion and spray can damage most tropical fruit trees, therefore, it is best to plant trees away from areas that experience saltwater intrusion or storm surge. Plant fruit trees on the highest part of your property or consider mounding the soil to raise the tree. When a tree has received salt spray on the leaves, wash off the leaf surface. When planting trees near ocean breezes try to provide a location that helps protect the tree from moist salty air. Look around your homes landscape for natural windbreaks like large trees or buildings. Many fruit trees are not wind tolerant so planting your trees behind a barrier of some type is smart. Lychee trees are not very wind tolerant or salt tolerant!
Initial fertilization can begin six weeks after planting. In general you can use a slow release 8-3-9 or similar formula that contains 2% to 4% magnesium plus manganese and iron. Fruit trees need to be sprayed with a micronutrient spray four times a year. Also, drench roots with liquid chelated iron twice a year.
Best of luck and plant a fruit tree!

Tip: Some nurseries grow many fruit trees under shade cloth. This is a common practice in the trade. Be sure to ask and if so, slowly acclimate the tree to more and more light before planting. This will avoid the possibility that the trees leaves will sunburn. This won't kill the tree but it won't look to good for a while. Be sure to water lightly if major leaf loss occurs.
