Apple Blossom Trees
Cassia javanica, or the apple blossom tree, can be a spectacular sight as it becomes a shower of showy pink flowers with sweeping, feathery branches, and in some areas, reaching a maximum height of 80 feet. This majestic tree makes an excellent shade tree during the summer, and its deciduous leaves allow light to stream through its branches in the winter.
Where to Plant
Choose a planting location for your apple blossom tree that will accommodate an average height of 30 to 40 feet, and if planting multiple apple blossom trees, plant 30 to 40 feet apart so their canopies can grow to their full potential. An area with full sun that has deep, well-drained soil is also crucial for apple blossom trees.
Apple blossom trees can be grown from seeds. Collect seeds from dried seed pods taken directly from the tree. Break open the pods to collect the apple blossom seeds, and remove the fleshy coating form the seeds by submerging in water. Dry the seeds in the sun. To stimulate germination, boil the apple blossom seeds in water and then allow them to soak in the cooling water for one day.
Medium amounts of water and nutrients will keep the apple blossom tree happy. Apply a light, well-balanced fertilizer such as 6-6-6 that contains ample micronutrients three times a year, preferably in the early spring, mid-summer and mid-fall. For smaller apple blossom trees, use less fertilizer every two months.
Apple blossom trees require a medium amount of watering that keeps the soil lightly moist but not over-watered. Wait until the soil is almost completely dry and before watering again.
Apple blossom trees will flourish when pruned properly. Pruning is best done after the flowering period has ceased. Remove any dead or diseased branches. Apple blossom trees have brittle branches so remove any branches that have broken off because of wind damage.
