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:

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.

How to fertilize Caladiums and other Aroids

By Ed Jones, the Booster Guy

Q: I have a large collection of Aroid plants, different Monsteras, Philodendrons, and several unique varieties of Caladiums. I've been always told that Caladiums should not be fertilized, they don't like it. Is it so?

A: Caladium farmers often say that these plants don't need any additional fertilizer and that they really don't like it... The thing is, caladiums do not like DRY fertilizers, and this is why. Most Aroid plants do not like being watered too often, so dry fertilizers in combination with infrequent watering create excessive salinity for the root system. We have run some tests on the proper fertilizers for caladiums and the best results were performed after using SUNSHINE Robusta. It is amino acid based, so the delicate, large-leaved Aroid plants will not have to work quite so hard to take up the nutrients, and there will be no nutrient lock up in soil. The nutrients are readily available to these plants.
In this article, you will see some test results of caladiums fertilized with SUNSHINE Robusta vs. other brands of fertilizer, with more vigorous growth and larger leaf size occurring after use of Sunshine Robusta...
