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 Care for Bat Lilies

by Top Tropicals Plant Expert Tatiana Anderson

🌞 Light

• Bright, filtered light. Morning sun or dappled shade is perfect.
• Avoid direct midday sun outdoors — it can scorch the leaves.
• Indoors, place near a bright window with sheer curtains or use a grow light.

🌡️ Temperature

• Warm and stable, ideally 70-85 F during the day.
• Protect from cold drafts or sudden chills.
• Ideally, do not let temperature drop below 45 F, although Taccas can tolerate short period of upper 30's.

💧 Watering

• Keep soil evenly moist but not soggy.
• Water when the top inch feels barely dry.
• Use lukewarm water.
• Avoid letting the pot sit in water.

💨 Humidity

• High humidity (60-80%) is key.
• Mist leaves often, use a humidity tray, or keep near a humidifier.
• In greenhouses or bathrooms with a skylight, it thrives naturally.

🌱 Soil

• Use rich, loose, well-draining mix
• Combine bark, peat, and perlite for ideal airflow around the roots.
• Best mix for growing tropical Tacca in pots - soilless potting mix Abundance . It provides perfect drainage and has a texture similar to a jungle rainforest media.

🍽️ Feeding

• During growth season (Spring through Fall), feed with Green Magic controlled release fertilizer every 6 months. For even better results, you may apply liquid fertilizer Sunshine Boosters Rubusta.
• Stop feeding dry fertilizer in cooler months when growth slows. Liquid Sunshine Boosters are safe to use with every watering, year around.

🏡 Indoor Growing

• Great for bright bathrooms, sunrooms, or any warm, humid corner.
• Rotate pot occasionally for even growth.
• Keep away from heating vents and AC drafts.

🌴 Outdoor Growing (in warm climates)

• Partial shade or filtered light under trees.
• Excellent in large containers that can be brought inside for winter.
• Shelter from heavy rain and wind.
