Pomegranate Vietnamese Red
This Pomegranate grows best in our South Florida climate. The tree rarely grows above 10 -12 feet. Fruit varies from baseball to softball sized. The fruit is sweet with a mild cranberry like flavor and produces good juice. You can squeeze out the juice by hand using an orange juicer.
Pomegranate fruit is loaded with antioxidants that provide many health benefits. Trim the tree regularly to maintain it's best appearance and overall tree health. Pomegranate trees are very cold hardy. They are also drought and salt tolerant.
The Vietnamese Red variety is often referred to as a tropical type pomegranate. We have found it to grow better than most other varieties from California such as Wonderful.
Vietnamese Red can tolerate our high humidity. The trees grow fast and often grow 3 - 4 feet per year. Tip prune branches in February to promote flowering in the spring and summer.
Pruning your tree:
Most three gal trees are about 3 feet tall. A good training method is to prune out any lower branches to develop a clear trunk. Pomegranate trees produce flowers on the new growth tips. Prune the tips of the branches on a regular basis to develop a nice non straggly canopy. When your tree is about three years old only prune out suckers and dead branches.
Provide a chelated micronutrient soil drench in December.
Be sure to use 2 -10-10 or similar formula fertilizer in January to promote flowering. In March and May use a 4-6-8 formula fertilizer and that's about all you need. Pomegranate trees don't require heavy fertilizer applications.
