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.

When Mango Ripens on the Tree, Everything Changes

Sunshine: Never understood the passion for mango. I tried store mangoes. I really tried. Just disappointment. So this is what real mango is supposed to taste like?

Smokey: Now you know.

There is a moment when a mango is perfectly ripe — soft to the touch, warm from the sun, fragrant before you even cut it open. The skin gives way, and suddenly there is color, juice, and a sweetness that feels almost unreal. Not sugary, but deep and layered, like something that took its time to become what it is. In that moment, it feels less like fruit and more like something truly given, exactly as it should be.

What you find in most supermarkets is something else entirely. Picked early so it can survive shipping, it never gets the chance to finish ripening process. It softens, it turns yellow, but the depth never comes. The flavor stays thin, and the texture often turns fibrous — strings in the flesh that get stuck in your teeth instead of melting away. That fiber is not an accident. It helps the fruit stay firm enough to handle transport without damage. It looks like a mango, but it never becomes one.

The only way to close that gap is simple — let the fruit ripe where it belongs. On the tree. When you grow your own mango, you control that moment. You pick it when it is actually ready, not when it has to survive a truck ride across the country. And that one difference is everything you taste.
