The coral tree is an amazing tropical plant that is a member of the legume family, Fabaceae. It may be spiny or smooth, deciduous or evergreen, with a spectacle of a flower in brilliant pink, red or orange hues. The average height of a coral tree is 35 to 45 feet tall, but some varieties exceed 60 feet in height. The leaves have three distinct leaflets and the stems may have thorns or may be smooth, depending upon their evolutionary adaptations. Coral trees need very little water. Too much water actually promotes a weak limb structure and subsequent breakage. Overwatering causes the tree to grow too quickly, and its soft wood cannot support such spurts. Then in the dry season, the weight of the tree can actually pull it out of the soil. Pruning the tree in spring to remove the heavier stems or any damaged material will help prevent limb loss and trees from tipping. Fertilizer is also not recommended when growing coral trees. Fertilizer also causes them to have aggressive growth that can cause problems later. Cover over the root zone with a good organic mulch, which will gradually leach a light dose of nutrients into soil over time.
