Wax Jambu (Wax Apple)
Crisp, juicy, lightly sweet fruit with a shine like it's been polished. A beautiful tree in flower and in fruit.
Syzygium samarangense
Glossy bell-shaped fruit that is crisp, watery, and refreshing, like biting into a mild sweet apple made mostly of juice.
Why it works here
Wax jambu is a beautiful, productive tree that earns its keep. The bell-shaped fruit is glossy and jewel-like, and inside it is crisp and so juicy that the water-to-flesh ratio is compared to watermelon. On a hot Florida afternoon, a cold wax jambu is pure refreshment. It is self fertile, so one tree fruits on its own, and it often bears two or three times a year. It loves our moisture, which is a nice change from the drought lovers. The main thing to watch is cold, since it prefers to stay above the mid 40s.
Care
Plant it in full sun in soil built up with compost, and keep it well watered, since this tree genuinely loves moisture and will fruit better for it. Mulch generously and feed with balanced organic fertilizer during the warm season. It responds well to pruning, so you can hold it to a comfortable picking height and open the canopy for airflow. Because it dislikes cold, give it a warm, sheltered spot and be ready to protect a young tree on a chilly night.
Common problems
Bland or watery fruit: fruit can be mild, especially if overwatered right at ripening or grown from a poor seedling. The fix is choosing a good grafted variety and easing off water as the fruit finishes.
Cold sensitivity: it does not like the mid 40s and lower. Site it warm and protect young trees in a freeze.
Fruit fly and cracking: soft juicy fruit draws fruit flies and can crack in heavy rain. Harvest promptly, clean up drops, and use organic cultural pest controls.
Common questions
What does it taste like?
Mild, sweet, and incredibly crisp and juicy, more refreshing than rich. Think of a light, watery apple crossed with a pear. It is about texture and thirst-quenching juice as much as flavor.
Do I need two trees?
No, it is self fertile, so a single tree fruits on its own, often two or three times a year.
Is it hard to grow here?
The main hurdle is cold. It wants to stay warm, above the mid 40s, so give it a protected spot and cover young trees on cold nights. Otherwise it is an easy, moisture-loving tree.
