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:

Use this plant food for your Canistel tree:
SUNSHINE C-Cibus - Crop Nutrition Booster

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.

Q:We are looking for a jasmine variety without thorns that we can grow on a wire fence...

A: All true jasmines (Jasminum spp.) are thornless. So you are safe to get anyone you like. The most vigorous, fast growing jasmines that grow into a vine, are:
Jasminum dichotomum
Jasminum pubescens
Jasminum nitidum
Jasminum officinale
Jasminum sambac Maid of Orleans - the most fragrant!

How to make Mango tree fruit

Q: Hello, I have a five-year-old Lemon Meringue tree that has only given me fruit one year. It put out about 50 mangoes and has done nothing for the past three years. Do you recommend any vitamins or any of the nutrients that you guys sell to help with this for next season?

A: We've had very similar problem with our Nam Doc Mai Mango tree, fruited once and no more next year. Usually the reason is nutrients deficiency, here in Florida we have poor soils. We applied Mango-Tango tree booster and it started flowering within a couple of weeks.
Generally, Mango flowering season is over by now, however, we recommend to feed the tree starting now, during active growth season. This way it will get better established before winter and also will store away all elements necessary for triggering flowering and fruiting. So by late Fall through Winter it will be ready to flower.
Along with the fertilizer, additional micro-element supplements will be beneficial. For improving fruit quality and increasing number of flowers, we also recommend to use SUNSHINE-Honey - sugar booster
