How to get Canistel tree to produce
without dropping flowers and fruit
Q: My Canistel tree is 3 1/2 years old and is growing very well, see the
picture below. It gets hundreds of pea sized "berries" but then they fall off. No
canistel fruit. What's wrong?
A: You have such a nice looking tree, it is a shame you can't get
any fruit to ripen.
In our experience, Pouteria trees dropping fruit prematurely is a very common problem.
There may be one of the following reasons, or a combination of them:
- Cold winters may affect production, and while Canistel is generally
pretty hardy tropical plant that can easily withstand short periods of chill, the
fruit may never form properly if it had a cold winter.
- Lack of water. Canistel tree is pretty drought tolerant, but for the
proper production cycle it needs regular irrigation. Especially during hot
summer.
- The tree may be not strong enough; young trees drop fruit very often when
they don't have enough "fruiting energy" built up in their system.
Your tree looks well established and vigorous, however, flower/fruit drop
is often a sign of insufficient nutrients of particular kind, usually Boron
(B) and/or Molybdenum (Mo): either when a tree is too young and not strong
enough, or because of poor soils and lack of necessary elements.
Here is what can be done, considering you live in a warm, frost-free
climate.
1. Provide regular fertilizing program. We recommend liquid
fertilizers Sunshine Boosters that are safe to use with every watering and year
around. It is beneficial to switch plants from traditional "slow-release"
fertilizer to the liquid one because it makes a huge difference in plant growth
and flower/fruit quality and quantity. See also:
- Why liquid fertilizers are better than dry
- Article about benefits of liquid fertilizers.
2. Apply micro-element remedies that are very effective for
improving fruit production, especially when flower or fruit drop occurs:
SUNSHINE Honey - promotes more efficient blossoming and pollination, makes
flowers bigger and reduces bud drop. SUNSHINE SuperFood - improves plant vigor and quality and size of
flowers
These are all natural, eco-friendly supplements that work great for fruit
trees and other edibles.

🌱 💪 Green Magic + SUNSHINE Boosters: A
Complete System for Strong Plant Growth
By Tatiana Anderson, Horticulture Expert at Top
Tropicals with Smokey & Sunshine help

revived from severe stress and growing vigorously.
☀️🌱 Sunshine Boosters: Complete Plant
Nutrition
Sunshine Boosters provide complete plant nutrition,
including Calcium and micronutrients that plants need for strong growth.
Because
nutrients are delivered in liquid form, plants can absorb them quickly and
respond almost immediately.
The Practical Problem
Liquid feeding works well, but it requires frequent application. In real
gardens, many growers simply do not have time to add liquid fertilizer with
every watering.
Green Magic: The Foundation
Green Magic solves this problem by providing steady
background nutrition through controlled-release fertilizer. It feeds plants
gradually, so they continue receiving nutrients even between liquid
feedings.
Why This Combination Works
Together, this system provides both complete nutrition and
steady feeding. Sunshine Boosters supply fast nutrients and
Calcium, while Green Magic maintains a stable nutrient supply between
feedings.
✍️ How to Feed Your Plants
📅 Step 1 – Start of the Growing Season
Apply Green Magic around the root zone every 6 months.
In ground:
Small Shrubs (1–3 feet): Use approximately 1/4
to 1/2 cup per plant
Established Trees: Use 1/2 lb to 1 lb of product per 1
inch of trunk diameter.
Small In-Ground Ornamentals: A common "spoon" rate is
roughly 1 teaspoon per gallon of estimated root volume (or per sq. ft. of
surface area).
Spread evenly around the dripline. Avoid piling the granules against
the base or trunk of the plant. For best results, lightly rake the granules
into the top 1–2 inches of soil.
Container plants:
Apply 1 tea spoon per 1 gal of soil (mix in with soil)
every 6 months during active growth period, or with every re-potting.
Water normally after application.
Adjustment for Temperature. Because Green Magic is
temperature-controlled, adjust your rate if your local climate is extreme:
Cooler Climates (<60°F average): Increase
the rate by 20% to ensure enough nutrients are released.
Hot Climates (> 80°F average): Decrease the rate
by 20% to prevent over-releasing as the heat speeds up the process.
☀️🌿 Step 2 – Active Growing Season
Apply Sunshine Boosters during the growing season.
Regular feeding (maintenance): Mix with tap water according to
the ratio on the label. For SUNSHINE Robusta use 25 ml (5 tsp)per
gallon
of water and spray leaves every 5-7
days during active growth.
Correction feeding ("medicine" dose): if plants show visible
nutrient deficiencies, combine SUNSHINE Robusta with SUNSHINE Superfood
and
spray every 5–7 days until new growth appears healthy. All SUNSHINE
Boosters
products are compatible and can be mixed with water in the same sprayer.
Best time to spray: early morning or evening when temperatures
are cooler and leaves can absorb nutrients efficiently.
Important: spray both the top and underside of leaves for
maximum absorption.

Why is the "Spring Fertilizer Rush" a problem?
Most gardeners apply a large amount of traditional fertilizer once in
March. This creates a "roller coaster" effect where plants get a sudden
spike of
nutrients followed by weeks of starvation. This leads to inconsistent growth
and potential "fertilizer burn."
What is "fertilizer burn"?
Traditional fertilizers are made of soluble salts. When too many salts
accumulate around the roots, they actually pull water out of the plant
tissues
(osmosis), dehydrating the plant and damaging sensitive root tips and leaf
edges.
Is there a difference between "Slow-Release" and
"Controlled-Release"?
Yes.
Slow-Release: Relies on natural factors like moisture
and soil microbes to break down. It is often unpredictable.
Controlled-Release: Uses engineered polymer membranes
(like Polyon) to release nutrients at a specific, predictable rate based
primarily on temperature.
Green Magic & Temperature
How does temperature affect my fertilizer?
Most fertilizers are lab-tested at 75°F. In hot climates
(90°F+), the nutrients release much faster. A "6-month" fertilizer
might only last 3
months in the summer heat.
How should I adjust Green Magic for my local weather?
Cooler Climates (<60°F): Increase the
application rate by 20%.
Hot Climates (> 80°F): Decrease the application
rate by 20% to prevent over-releasing.
The Calcium Gap
Why doesn't Green Magic contain Calcium?
Calcium salts are highly soluble and can destabilize the polymer coating
used in controlled-release granules. Therefore, most high-quality granules
leave Calcium out. You can provide Calcium by using SUNSHINE Boosters
Why is Calcium so important for new growth?
Calcium is the "bone" of the plant, building strong cell walls. Unlike
other nutrients, it is immobile—the plant cannot move it from old
leaves
to new ones. If you don't provide a constant supply, new leaves and fruit
will
emerge distorted or weak.
Advanced Science & Troubleshooting
What makes Sunshine Boosters "Bioavailable"?
Unlike most liquid fertilizers that use EDTA chelators, Sunshine Boosters
are amino-acid based. They use organic acids and glycine to escort minerals
into the plant, allowing it to incorporate nutrients into its proteins
almost
immediately.
Will these fertilizers affect the taste of my fruit?
No. Sunshine Boosters are made from pharmaceutical-grade components and
contain no urea or harmful salts, ensuring your harvest (like Mangoes or
Avocados) has a pure, natural flavor without a chemical aftertaste.

How to fertilize herbs and vegetables
Q: We moved to Florida from New York earlier this year. My wife
and I used to grow many fresh veggies and herbs in our garden up North during
Summer, but it seems like in hot Florida the season for them is not until
Fall. So we are preparing the beds and also looking for some organic fertilizer
solutions. We've heard a lot about your natural Boosters and wonder if they can be used in our vegetable garden?
A: You came to the right place for organic fertilizer solution.
Sunshine Boosters are based on organic amino-acids and are completely natural,
non-toxic, eco-friendly, and do not build up nutrients in the soil. Their
mild formulas designed specifically for edibles.
We just have started our own vegetable garden with some Biquinho and Wiri Wiri peppers, cherry tomatoes, and basil, and will be adding more
as the the weather cools down.
For small scale gardens (both vegetables and herbs), you can start with Sunshine Robusta - a total feed "all on one". All necessary elements are provided in just one bottle, both macro- and micro-elements, it is a scientifically balanced formula. For larger gardens, especially if you have fertilizer injector system, we recommend
Sunshine Boosters Pro Series - this product is much more economical, and
you will need to mix only 3 solutions into your watering tank at the time of
watering.
For more information, please contact our Booster guy Ed Jones, he can help you with selection and dosage information. Sample Discount program
is available for samples of Sunshine Pro.
