Healthy Plants: Q&A from Mr Booster

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:

Once temperatures stay above 65F, growing season starts for tropical plants.

1. Increase watering as soon as you see new buds opening and new leaves growing

2. Trim all dead or damaged wood 1-2 inches above new growth

3. Apply the following treats to make your plants happy:

- granulated balanced fertilizer

- SUNSHINE Superfood microelements as foliar spray for healthy growth, profuse flowering, and disease/bug resistance

- SUNSHINE-E to help plants come out of dormancy faster and increase metabolism. 100 ml bottles and 50 ml bottles available for large plant collections.

- SUNSHINE-Honey to fruit trees so you can enjoy sweeter and bigger fruit later this year

4. If nights are still chilly, take potted plants outside to enjoy the afternoon sun and bring them back indoors for the night.
