How to establish Tabernaemontana
and get more fragrant blooms

Q: I purchased Tabernaemontana australis from you back in June of this year and it recovered just fine, but the new growth got some chlorosis. Older leaves still look normal. The flowers also look normal but lack fragrance. Since I live up north, I have it in a heated greenhouse for the winter, with a grow light to compensate for the short days. I have it in a 10 inch clay pot in a mix of equal parts standard indoor potting soil, peat moss, and perlite. It gets fed with half strength 10-10-10 about once a month on average. Is there some specific culture that you would recommend for this plant ? I really love it and want it to thrive.

A: Tabernaemontana is a plant that may take some time to establish itself, and leaf chlorosis often becomes a common issue when the root system is not well-established. This symptom is indicative of Iron deficiency, and possibly other micro-element deficiencies, such as Boron or Molybdenum, which become more apparent when the plant receives excessive water. This problem tends to intensify as temperatures drop, particularly when a combination of cool and wet conditions prevails. It's worth noting that your potting mix seems to be appropriate for this plant.

In light of these circumstances, we recommend the following steps:

1) Reduce watering during the cooler season, especially when daylight hours are shorter. Allow the top layer of the soil to dry before watering again.

2) Consider supplementing with microelements using a product like Sunshine Superfood. You can apply this as a foliar spray and mix it with your watering can.

3) Maintain your regular fertilizing program throughout the winter months, but ensure that you use only liquid amino-acid fertilizer, such as Sunshine Megaflor. Follow the instructions on the label for the correct dosage and apply it with each watering, even during the winter. Since you will be reducing amount of water, the amount of fertilizer also will be adjusted accordingly.
Important: do not use any dry fertilizers during winter months (Nov-March).

Regarding the fragrance of the flowers, they typically emit a mild, sweet scent, although it may not be as potent as that of gardenia or jasmine. The strongest aroma usually becomes more prominent during warm (but not excessively hot) and humid conditions, particularly in the morning hours. As the plant grows larger and healthier, the fragrance should become more intense because the flowers produce more essential oil when the plant is robust. You may also apply Sunshine Honey supplement to improve flower quality and fragrance strength.

10 secrets of growing a perfect Mango tree

Grow Your Own Food

How to grow a healthy and productive mango tree?

1. Right variety. Select a vigorous grower for in-ground planting, or a condo mango cultivar for growing in container. More info on varieties.
2. Soil must be well-drained. If planted in the ground, plant on a little elevation (see How to plant a tree)
3. Full sun is a must. The more sun, the more flower and fruit.
4. Water. Keep mango tree on a dry side, water young trees regularly but let top of the soil dry before next watering. Mango trees don't like wet feet.
5. Air circulation is important for mango tree to eliminate diseases. Allow enough space from other trees and buildings.
6. Fungicide. Mango leaves are very susceptible do fungal issues, especially in humid climates likÑƒ Florida. Spray fungicide (Copper or similar) according to the label, once a month.
7. Fertilize year around with every watering with liquid fertilizer Sunshine Boosters Mango Tango. Apply Micro-elements once a month and use other good supplements.
8. Shape. Check out Video: - to shape the most vigorous and productive tree.
9. Protect from hard freeze. Mango tree doesn't take freezing temperatures well. In subtropical areas Mango can be protected. Alternatively, it can successfully produce in container, if moved indoors during cold weather.
10. Fruit. Mango tree produces thousands of little flowers, many of them can set fruit. Do not let a small, young tree to keep more than 1-2 fruit, remove extra, to avoid exhaustion. Allow 2-3 years for the tree to establish until it produces a full crop. Apply Sunshine Honey supplement to your tree for sweeter fruit.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:
1) Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4) Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.

How to make Sapodilla fruit profusely?

Sapodilla - Manilkara or Achras zapota, the Brown Sugar Fruit

🍊 How to make Sapodilla fruit profusely?

Sapodilla - Manilkara or Achras zapota), the Brown Sugar Fruit is a warm-climate evergreen fruit tree that can produce a lot of fruit once conditions are right. So why do so many sapodilla trees grow beautifully, flower heavily, and still refuse to set fruit?

Sapodilla Fruit Production - What Really Matters

1. 🌳 Choose the Right Tree
Grafted or air-layered trees fruit much sooner - typically in 1-2 years - and more reliably than seedlings, which may take 6–8+ years.
Some varieties are more profuse producers than others. For example, Silas Woods is virtually everbearing, Hasya is commercial prolific producer, Oxkutzcab (or Ox) -is also heavily productive (learn more about varieties).

2. ☀️ Environment: Heat, Sun & Water Balance

Temperature and Humidity
Excessive heat above 90F and low humidity can cause flowers to dry up and fall before setting fruit.
Solution: Provide filtered light or shade during the hottest part of the day to reduce heat stress on blossoms.

Water
Sapodillas are drought tolerant, but consistent moisture during flowering and fruit set improves fruit retention.
Avoid waterlogged conditions - soggy soil can stress roots and reduce yield.

Sun Exposure
Full sun is best for growth and flowering - but for hot climates, protection during peak afternoon heat helps reduce flower drop.
Young trees can also suffer sunburn.

3. Fertilization: Feed for Fruit, Not Just Foliage
Good nutrition is critical for flowers to turn into fruit. Apply a routine feed through the growing/flowering season - contolled-release (Green Magic) or liquid (Sunshine C-Cibus) both work.
Balanced fertilizer with trace elements like Boron (B), Molybdenum (Mo), Iron (Fe), and Copper (Cu) is essential for fruit set and development. Boron & Molybdenum deficiency as a frequent cause of flower/fruit drop in container-grown trees (nutrients get depleted quickly in pots).
Micro-nutrient sprays 2-3 times per year help improve fruit retention and quality. Some growers use sugar boosters (Sunshine Honey) or micronutrient blends that include Mo & B to help fruit set (Sunshine Superfood).

4. 🐝 Pollination - Often Overlooked
Sapodilla flowers are small and often require pollinators for best fruit set.
In some regions, small insects like thrips are key pollinators.
In places with low insect activity, hand pollination dramatically increases fruit set - brushing pollen from one flower to another with a small paintbrush during peak bloom times can help.
Placing fruit scraps (apple peels/banana peels) under the tree to attract beetles is an inexpensive way to boost insect activity.

5. ✂️ Pruning and Tree Structure
Moderate pruning can help open the canopy for better light penetration and air circulation, which supports flowering and reduces stress. Training young trees promotes a strong branch structure that can carry more fruit later. Sapodilla flowers on young growth (tips of the branches).

6. Pot vs Ground: Size Matters
If your sapodilla is in a container, root bound trees struggle with fruit set because roots run out of space and nutrients - stepping up to a larger container or planting in the ground can help.
Root-bound trees often bloom but fail to develop fruit.

7.

📅 Patience & Timing

Even healthy trees can take years to start fruiting well.
Trees often flower repeatedly but only set fruit when environmental conditions and pollination align - especially important for young or newly planted trees.

📌 Summary Checklist for Better Sapodilla Fruiting

✔️ Choose a grafted variety (faster, more reliable fruit).
✔️ Manage heat & humidity - shade during hot hours.
✔️ Water consistently but avoid waterlogging.
✔️ Fertilize balanced NPK + micronutrients (include B & Mo).
✔️ Encourage pollination

Healthy Plants: Q&A from Mr Booster

Fertilizing in Winter

Q: I have many tropical plants in my garden, both in the ground and in pots. I realize it is wintertime and some of them, the Hydrangea, Hibiscuses, and roses are in bloom but the rest of them seem wilty and droopy. Is it alright to fertilize them now, or should I wait for a few days? I have an all purpose tropical fertilizer and a 20-20-20 also. Please advise what to do.

A: During wintertime, tropicals may suffer from low temperatures and lack of sunshine which causes droopy leaves, and leaf loss.
Regardless of the cause and plant condition, you should NEVER apply traditional dry fertilizers during cool months. When cold, dry fertilizers (EDTA-chelated) may create nutrient lock up in soil and damage the roots. Dry fertilizers (both granulated and water-soluble) can be used only during hot season - when min temperatures stay above 65F for at least a week in a row, and daytime temperatures are over 75-80F. During hot, active growth season plant metabolism increases. This provides less chance for a chemical root burn, as the nutrients are used up quickly.

However, liquid fertilizers, as long as they are amino-acid based, can be used year round. From our own experience last winter, we discovered that fertilizing sickly looking plants (with signs of cold damage and root issues) with Sunshine Boosters actually revived those plants. Sunshine Boosters even brought back to life some hopeless specimens. Take a look at this gardenia that grows in our garden (picture above). See full article.
In your case, it would be beneficial to use a mild formula of liquid boosters in combination with Sunshine Epi -a natural plant hormone that boost their growth and helps to cope with cold-, temperature- and low-light-related stress.

These are the products we recommend:
- Sunshine Bombino - add to every watering
- Sunshine Epi - twice a month as foliage spray

Since you grow plants in pots, feeding program is especially essential, because plants are limited with a container size where roots can't reach out to more food in the outer soil. In professional nursery set up with injector irrigation systems, container plants are fed daily (depending on season, more than once a day) with every watering. This is why greenhouse plants are so healthy looking.
So feel free to give your plants Sunshine boosters with every watering, dozing according to the label. During cold period, plants need less frequent watering, so fertilizer input will be balanced accordingly, it will depend on temperature and plant metabolism.

Sunshine Bombino - mild, "pampering" formula for young and tender plants, as well as plants recovering from stress and/or winter damage.
