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:

Use this plant food for your Canistel tree:

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.

Happy Thanksgiving from all of us at Top Tropicals!

Smokey: "We made a list of everything we are thankful for this year."
Sunshine: "I helped. Mostly by napping next to it."
Smokey: "And that is exactly why sunshine naps are on the list."

Smokey and Sunshine wanted to share a short Gardener Thanksgiving Message about what they are thankful for this year:

"We are thankful for warm laps during cold mornings.
Thankful for every gardener who stopped to scratch our heads between loading carts.
Thankful for the smell of fresh soil, new plants, and boxes that make perfect cat forts.
Thankful for mango season (even though humans never let us eat the fruit).
Thankful for sunshine naps on potting tables and shade naps under benches.
Thankful for all the tiny moments when gardens and people slow down together.
And thankful that we get to share this tropical adventure with you."

From the whole Top Tropicals Team and PeopleCats, we wish you a warm, peaceful, plant-filled Thanksgiving 🙏 ♥️

Thank you to everyone who came out and supported our Holiday Plant Market last Saturday, December 13, 2025. It was great to see familiar faces, meet new visitors, and watch the garden fill with people exploring, asking questions, and choosing new plants to take home. Our CatsPeople were busy greeting guests, supervising carts, and making sure everyone felt welcome. Your support and good energy are what make these events special for us. We hope your new plants settle in beautifully, and we look forward to seeing you back in the garden soon!
