Helping Citrus and other fruit trees with Nutritional Supplements

Q: Can you recommended a product to help with my citrus? Combating greening and chlorosis.

A: Citrus greening is spread by an insect called the Asian citrus psyllid. The psyllid feeds on the stems and leaves of the trees, infecting the trees with the bacteria that causes citrus greening. Florida Citrus growers dedicated the last decade to researching citrus greening. Officially, currently there is still no cure, however, some Nutritional solutions have shown promising results. To slow the progression of citrus greening in infected trees, nutrients are applied to the leaves and to the roots. Providing better nutrition helps trees fight against citrus greening and enables them to continue to produce quality fruit.

We recommend the following products for use on regular basis:

SUNSHINE Epi is a natural Brassinosteroid plant hormone and a bio-stimulant that may be very effective as citrus greening treatment. It works through plant's immune system and shows amazing results of recovery of weak and sick plants.

SUNSHINE Superfood, a complex micro-element supplement, maintains plant's health and provides vigorous growth.

SUNSHINE-Honey is a basic nutritional complement, it contains essential plant micronutrients Boron (B) and Molybdenum (Mo). These elements are essential to vegetative and reproductive growth, cell expansion, tissue growth, and fertility. A very common problem for most unimproved garden soils is lack of Molybdenum and Boron as soil micro-component. This results in underdeveloped / low quality fruit and/or premature fruit drop. Applying SUNSHINE Honey on your fruit trees will fill that gap and help a fruit tree to form a healthy fruit.

Macro-nutrients should be applied in combination with micro-nutrients on regular basis:

Mango-Food - Smart Release Fruit Tree Booster (works great for all tropical fruit trees)
Fruit Festival Plant Food - Ideal blend designed to improve fruit trees health and vigor, and increase crop yield.

Healthy Plants: Q&A from Mr Booster

How to grow a happy Red Jade Vine?

Q: My Red Jade Vine has the leaf tips turning brown. I water this plant four times a week and I am using a half a teaspoon of miracle grow bloom booster 15-30-15 per 2 gallons, every two weeks. In the beginning I had to water this plant off city water in South Fort Myers. Over the last two months I picked up a dechlorinator buggy plus threw that on my hose and I've been watering it with that but it didn't seem to make a difference. I put this plant in the ground last September. It has three shoots that run into the top of the tree, so it is growing but leaves seem to drop off down low at the base of the vine and the brown tipping running into the top of the plant. But not the newest shoot its leaves are solid green all the way at the top. Thanks for any advice.

A: Mucuna benettii - Red Jade vine - is not the easiest plant to grow, and we are glad your vine is growing well. For those who love this plant but not ready to face all challenges, we recommend its cousin - Camptosema grandiflora - Dwarf Red Jade Vine, which is much hardier and easier plant.
We looked at the photos and these are our thoughts.

1) The top of the plant with green fresh leaves definitely indicates that the plant is generally healthy and vigorous.
2) Dry tips of the old leaves may indicate excess salts in soil, in combination with the summer heat that it went through. Based on your feeding program description, that fertilizer may create a problem. Water soluble traditional fertilizers are EDTA-chelated which often causes nutrients lock up in soil and leaf drop. Try to stay away from that fertilizer for a month and let the rains and/or irrigation water flush the soil for a couple of weeks.
3) Red Jade vine is a very sensitive species. Normally, during hot season it is safe to use traditional fertilizers, especially slow-release granulated. However, with this plant we recommend you to switch to more delicate formula and use only liquid fertilizer.
SUNSHINE Megaflor - Bloom Nutrition Booster will be the best. It is safe to use it as frequent as with every watering! It is amino-acid based, and will be totally consumed by the plant without nutrient lockup.
4) Another cause of dry leaf tips may be micro-element deficiency.
Megaflor booster already has all necessary micro-nutrients in it, plus you may apply some extra: SUNSHINE Superfood.
5) You may continue using regular water for watering (including city water) as long as you use amino-acid based plant food and supplements: they improve soil acidity (what tropical plants like is acidic soil, and Florida soils are alkaline). Additionally, to improve soil acidity which can be critical for this Mucuna species, you may add 1" layer of pure peat moss on top of the soil around the plant. Please keep us in loop how the plant is doing. It is pretty rare species in cultivation and we will be happy to help you to keep it thriving.

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.
