Healthy Plant Food: Q&A from Mr Booster

Why my Sapodilla is not fruiting?

Q: I bought a Sapodilla tree from you several years ago, Silas Woods. I live in Houston area. The tree grows and produces blossoms for fruits, but then they just dry up and fall off. To-date, I have not gotten any fruits off the tree. Is there a reason for this? I really want a fruiting tree because Sapodilla is one of my favorite fruits. I have attached pictures of the tree. Please help.

A: Silas Woods is a free-flowering variety and in favorable conditions it should produce fruit almost year round, considering warm temperatures. The fact that the tree is producing flowers indicates that it is strong, overall healthy and ready for production, but for some reason these flowers don't set fruit. There may be several reasons for such behavior.

1) Too high temperature and too low humidity
In Houston area, humidity should be good in summer. However, if temperatures stay above 90F for a long time, this may cause flower dry-n-drop.
Solution: try to move the potted tree into filtered light, or in a spot where it does not get direct burning sun during the hottest hours of the day (morning sun is the best)

2) Root bound.
Solution: check if the tree needs stepping up into a larger container.

3) Lack of certain nutrients that are responsible for proper fruit formation.
In particular, elements B (Boron), Mo (Molybdenum), and a few other micro-elements (Fe - iron, Cu - Copper, etc.). This is most likely the cause of a flower drop. This is very common reason for undeveloped fruit or lack of fruit in container-grown fruit trees. When grown in the ground, plants can reach out to all necessary elements in surrounding soil (considering soils are not too poor on necessary elements). In a pot, a supply of nutrients can be exhausted very quickly, so a quality fertilizer program is very important. Fertilizer must include all necessary nutrients in easy accessible form, and a plant must have their constant supply for proper development.
Solution: prescribe to your Sapodilla tree the following combination of plant food:
- SUNSHINE C-Cibus - Crop Nutrition Booster. It will provide well-balanced amounts of high absorption Nitrogen, as well as other macro-elements - to provide enough energy to the tree, plus a combination of all necessary micro-elements. It is safe to apply this fertilizer as frequent as with every watering, including winter time.
- SUNSHINE-Honey - sugar booster. This supplement has a high content of elements Mo and B - once the tree starts getting them on regular basis (a few times a year, according to the label), it will change its habit dropping flowers and/or premature fruit drop. As extra bonus, Sunshine Honey makes fruit sweeter by bringing sugars from all over the plant and concentrating them into fruit.

4) Lack of pollinating insects.
Solution: For most effective pollination, we always recommend to put some pieces of fruit under the tree, apple peels, or even banana peel. Those attract tiny beetles that are responsible for small flower pollination.

With winter time approaching, fruiting season is about to end, however, do not get discouraged and start the fertilizing program right away: this will bring up the plant into a healthy stage within a few months, and by next season it should be covered with fruit you like so much! Remember, Sunshine liquid fertilizers can be used year round, including winter, without a risk to burn roots or overdose, as long as you follow label instructions.

Mango Practical Growing Tips (Keep It Simple)

• Sun: Full sun is key. 6–8+ hours daily for best growth and fruiting.
• Soil: Excellent drainage is critical. In pots, use well-draining mix with added perlite or sand. Mango does not like wet roots.
• Watering: Water deeply, then let soil dry slightly before watering again. Avoid constantly wet soil.
• Containers: Excellent for pots. Condo mango varieties stay compact and are easy to manage on patios.
• Feeding: Light but consistent feeding during active growth makes a big difference. Use controlled-release Green Magic for steady nutrition, and supplement with liquid Sunshine Boosters Mango Tango during warm months to push growth and fruiting.
• USDA Zones: Best suited for Zones 9b–11. In Zone 9b, choose a warm, protected microclimate (south-facing wall, patio, or near structures) and be prepared to protect during cold snaps. In Zones 10–11, mango grows reliably in-ground. If you live in colder zones, grow in a pot so you can move the tree indoors or protect it during cold weather.
• Cold Protection: Protect young trees during cold nights. Use cover or place near a wall or warm microclimate. Mature trees are more tolerant.
• Airflow: Good airflow helps prevent disease and keeps growth clean.
• Spacing: Give the tree room for light and airflow. Even compact trees benefit from space.

Mango Winter Care (Very Important)

Mango is not a truly cold-hardy plant. It performs best in USDA Zone 9b and warmer, where freezes are rare and short. In borderline areas, winter protection becomes part of the routine. Mango trees should be covered during cold nights, and planting near a south-facing wall helps protect from cold winds. That small microclimate can make a real difference. If your winters are less predictable, growing mango in a container becomes the simplest solution. It gives you full control — you can move the tree to a protected space when temperatures drop, and bring it back into the sun when conditions improve.

That is where condo mango varieties make the most sense. They are naturally compact, easier to manage in pots, and still produce full-size, high-quality fruit. You get all the benefits of a mango tree without needing a large yard or perfect climate — just sun, a container, and a bit of seasonal movement when needed.

Growing Mango in a Pot (Condo Mango Made Easy)

Growing mango in a container is one of the easiest ways to control size, soil, and winter protection. Condo mango varieties stay naturally compact and adapt well to pots, making them ideal for patios, small spaces, or colder climates. You get full flexibility — move the tree when needed, manage its growth, and still enjoy real tree-ripened fruit.

• Pot size: Start with 3–7 gallon, move up to 15–25 gallon as the tree grows.
• Soil: Use fast-draining mix such as Abundance soilles mix.
• Sun: Place in full sun. More light = better growth and fruiting.
• Watering: Water deeply, then let soil dry slightly before next watering.
• Feeding: Use controlled-release Green Magic for steady nutrition, plus liquid Sunshine Boosters Mango Tango during active growth.
• Climate Flexibility: Can be grown in any USDA zone when kept in a container. Simply move indoors or to a protected area during cold weather to keep the tree safe.
• Pruning: Light pruning keeps the tree compact and productive.

Once you taste a real mango from your own tree, everything changes. It is no longer something you buy — it is something you grow, wait for, and look forward to every season. What felt like hype suddenly makes sense. The passion people have for mango is not exaggerated — it just comes from a completely different experience.

And for people who have never tasted a fresh, juicy mango warmed by the sun, that moment comes as a surprise — the first time they realize what mango is actually supposed to taste like.

As Smokey quietly puts it: Now you know.
