Q&A from Mr Booster
Plant food for a Star Fruit
Q: I have 2 Starfruit plants from you. One on the left is B10 has a lot of flowers but no fruit is developing. On the rite is Kenjeng. This one has no flowers at all. Both plants are growing very well. Plenty of sun and water. I am located in Boynton Beach Florida. So what to do?
A: Your trees on the pictures look very healthy, congratulations
with a great care!
Starfruit, as well as other grafted fruit trees (like mango, avocado, etc)
usually flower/fruit easily and readily while in pots in the nursery.
Sometimes, once planted in the ground, they may reduce flowering or even stop
flowering. What happened?
The answer is simple. In pots, we fertilize them on regular basis. In our
nursery, we have fertilizer injector inline with irrigation system that dozes
plant food with EVERY watering. In other nurseries, they may also use
slow-release fertilizers, but it is still a regular routine to provide plant food to
potted plants.
In the ground, especially in Florida poor soils, fruit trees may stop
flowering or delay fruiting due to lack of nutrients, or dis-balance of elements
in the ground. Without fertilizer, a tree may take extra time to develop
bigger root system to reach out for necessary elements, and eventually will start
fruiting anyway.
But we want it to fruit soon! The only way to fix the problem is to provide
fertilizer on regular basis for a young tree. It is especially important
during hot summer months when plant metabolism is fast due to high temperatures,
plus nutrients may get washed away with frequent summer rains (like we have
in Florida) even if you've added some fertilizer at time of planting.
You can use smart release fertilizer once a month during hot season,
this one or similar:
Mango-Food - Smart Release Fruit Tree Booster.
But the most effective way to get a tropical tree to flowering and
fruiting, is frequent applications of liquid fertilizer. We use Sunshine Boosters
with every watering on our plants. They work great even on hard cases and
weak plants, and you see the difference in a matter of weeks, sometimes even
days.
We recommend the following fertilizer that contains all necessary elements
for young fruit trees:
SUNSHINE C-Cibus - Crop Nutrition Booster
SUNSHINE C-Cibus - Crop Nutrition Booster from Garden Series, or Combo Total Feed Collection - all nutrients in just one bottle, for fruit trees and edibles.
