Video by Scott Riddle

Discover the cool story of Scott Riddle, a well-known plant enthusiast with a popular YouTube channel dedicated to his tropical plant collection. In this video, Scott shares his firsthand experience with our Sunshine micro-element kit, designed to enhance the cold hardiness of plants.
Living in the unpredictable climate of the California mountains, where he cultivates tropical plants in a zone higher than recommended, Scott faced the challenge of unexpected freezes. The boosters hopefully will be a game-changer for him, reinforcing his plants for the winter season. This insightful and detailed video is a valuable resource for anyone engaged in zone-pushing, aiming to fortify their tropical plants against the rigors of challenging weather conditions.

Here at Top Tropicals, we have already applied two pre-winter treatments of Sunshine Power-Si formula, in combination with the bio-stimulant Sunshine Epi and micro-elements. One in November, the second one in the beginning of December. So far, after a couple of cold nights, the plants still look happy. Stay warm and get prepared!"

Q: Are there any tropical plants that will do well if I order them in Winter? We just bought a house in New Jersey with a large sunroom, and I can't wait to fill it with tropical beauties! Should I wait until Spring, or do you have something for a Winter start?

A: This is indeed a very good question, as many tropical plant collectors grow their treasures outside the tropics. The short answer is - yes! You can start filling your tropical sunroom any time of the year, but some plants are easier to deal with in Winter than others. Below are some guidelines.

Winter bloomers: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis

Winter bloomers today, left to right: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis.

1. Plants that prefer Winter shipping to avoid overheating stress:
- All plants with lush foliage such as Philodendrons, Medinilla
- Trees with fine feathery leaves such as Moringa, Jacaranda, Poinciana
- Some fruit trees sensitive to overheating during shipping: Papaya, Stawberry Tree, Starfruit (Carambola), Bilimbi.

2. Subtropical plants that are relatively cold hardy
- Fruit trees: Loquats, Olives, Avocados, Tropical Cherries: Eugenia, Malpighia, Noni (more cold hardy than you may think), Canistel.
- Flowering trees: Champaka, Tabebuia.
- All Bananas

6. Winter plant care. During Winter the daylight is shorter and temperatures are cooler.
- Reduce watering
- Use only liquid amino-acid based fertilizer Sunshine Boosters (safe to use year around)
- Monitor insects.

7. Shipping in Winter. We ship year around. However, if it gets below freezing in your area, you may use FedEx Hold location, they are temperature controlled so you don't have to worry about a box being dropped off at your cold porch outside.

8. A note for mild climate residents. Most tropical plants can be planted in the ground year around. Some ultra-tropical tender species such Chocolate tree, Ylang Ylang, or small size Mango trees can be grown in pots until Spring and planted out once chances of cold spell are gone. Until then, they can be moved indoors for cold nights.

Think outside the box and bring tropical paradise indoors during the time when we need warmth the most! Tropical plants will brighten your short winter days and help you to have truly HAPPY HOLIDAYS!

How to grow a happy Moringa Tree

Moringa tree in the garden

Q: We purchased some tropical edible and medicinal plants from you in August this year. I have a question pertaining to our Moringa tree. When we purchased it, it was about two foot tall. It has put on tremendous growth and is now a little under ten foot tall. My question is, should a Moringa be losing lower leaves at this point? The bare limbs are still green and the top looks to have healthy green leaves.

A: Thank you for choosing our Moringa tree, and sharing the picture. It's great to see that your tree appears healthy and happy - it's a resilient plant. Given the relatively dry Fall we've experienced this year, a little extra water can make a significant difference.

Here are some suggestions to ensure your Moringa thrives:

Moringa branch with flowers

Watering: While Moringa is generally drought-tolerant, during dry periods, in addition to relying on your lawn sprinkler system, add some extra water with a hose. Adequate moisture is crucial for maintaining healthy foliage.

Pest Control: Moringa is not only a nutritious plant for humans but also attracts pests that appreciate its medicinal properties :) If you notice insect damage on the leaves, consider spraying with Neem oil or using an over-the-counter systemic insecticide containing imidacloprid or a similar ingredient.

Seasonal Behavior: Moringa trees are semi-deciduous to deciduous, and their leaf-shedding behavior can vary depending on the climate. In Florida, for instance, it's common for Moringa trees to shed leaves in the Fall. However, this is a natural process, and you can expect new growth in the Spring.

Fertilizing for Vigorous Growth: To promote the most vigorous growth of your Moringa tree and other plants in your garden, consider implementing a fertilizing program. If using dry, slow-release fertilizers, apply them only during the active growth season: from March through November. If you're looking for a year-round solution, liquid amino acid-based formulas like Sunshine Boosters can be a great option. You can easily add them to your watering routine or use injectors like The Robuster for convenient and consistent feeding. If you're planning to expand your garden with other medicinal plants or an edible forest, The Robuster smart fertilizing system is an excellent choice, offering the most efficient, care-free way to nourish your plants with natural nutrients throughout the year.

How to establish Tabernaemontana
and get more fragrant blooms

abernaemontana australis flowers

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.

Prepare your plants for Winter with Sunshine Boosters

Tropical Plants on Winter Windowsill

We usually stop using dry slow-release fertilizers from November to March. However, liquid Sunshine Boosters, which are natural plant food, can be used all year. They help your plants survive winter. When it gets colder, we water less, so the fertilizer decreases too. The plants only use what they need. To learn more about how Sunshine Boosters work and why they're safe and helpful, check out this blog: Using Sunshine Booster during Winter.

Sunshine boosters formulas

Apart from giving your plants nutrients during winter, you also can improve their ability to handle the cold. Try the Sunshine Boosters supplement kit for tropical plants. Follow the schedule and use three different supplements: SUNSHINE Superfood, SUNSHINE Epi, and SUNSHINE-Power-Si. Read more about treatment with Sunshine boosters supplement kit.

How to help a weak tree to recover and thrive?

small and large lychee tree

Q: Look at my sad looking Lychee tree. Can you share with me any ideas about this tree condition?

A: From the photo (left), we see a few potential issues. The problem might be due to a combination of factors such as a heavy potting mix with poor drainage, over-watering, an underdeveloped root system sensitive to these conditions, leaf burn, and a lack of nutrients.

Suggestions for fixing the problem

1. Soil mix. First, assess the quality of the soil. If the plant has been in the same pot for a while, the soil at the bottom may have become compacted, leading to poor drainage. If this is the case, carefully remove the root system from the existing soil (by removing excess soil around the roots without disturbing the roots themselves). Repot the tree into fresh, well-draining potting mix with good drainage characteristics, which typically contains materials like bark and perlite. Ensure that the new pot is exactly the size of the root ball; using a significantly larger pot can lead to soggy conditions that harm the roots.

2. Light. Place the potted tree in an area with filtered light, avoiding direct sunlight throughout the day.

3. Water. Control the watering. During this recovery period, your plant will need very limited water until it shows signs of improvement and new growth. After repotting, water it thoroughly just once, and avoid watering again until the top layer of soil becomes dry. Then, water as needed. Avoid keeping the soil consistently wet, especially during rainy periods. Protect the plant from excessive rain.

4. Supplements. Consider applying Sunshine Superfood micro-elements following the label instructions, once a month. Additionally, using Sunshine Epi bio-stimulant, sprayed every other week, can help the plant recover from stress and encourage growth. You can also use Sunshine C-Cibus at half the recommended concentration with each watering. Hold off on any other fertilizers until the plant has sufficiently recovered and begins to show signs of new growth.

5. Transplanting. If you plan to transplant the tree into the ground, it's advisable to wait until spring when nighttime temperatures consistently stay above 65F for at least two weeks.

6. Temperature. Keep the tree in a warm environment. When temperatures drop below 50F, bring it indoors.

These steps should help the tree recover, grow healthy leaves, and establish a better root system, preparing it for successful transplantation into the ground or a larger container, ensuring a happy and productive life ahead.

Growing Barbados Cherry in container

Barbados Cherry fruit on the branch

Q: I am interested in buying some Barbados cherry plants. Could you please advise if these can be grown in containers indefinitely or it's still better for them to be planted in ground for nutrients etc?

A: The Barbados cherry, like other tropical cherry varieties, is exceptionally well-suited for cultivation in containers.

Barbados cherry grows into a dense bush, demands minimal pruning, and begins bearing fruit at a young age. Our plants, which are propagated from cuttings, initiate the flowering and fruiting process in the very same year. They produce fruit almost year around. This year we've had three big crops: April, July and October (still fruiting now!) besides sporadic fruiting throughout the warm season.

Barbados Cherry branches with fruit

You can cultivate Barbados cherry in a pot, commencing with a 1-3 gallon container and gradually increasing the size each year. Below is a photo of a fully developed tree in the ground, for reference. This tree is approaching its third year of growth. When grown in a container, it maintains a more compact size, with the largest container needed likely being between 7 to 15 gallons. Regular pruning can be employed to keep it smaller.

Barbados cherry (Malpighia) possesses a distinct growth pattern that sets it apart from other tropical cherry varieties - Eugenias. Malpighia's branches can assume peculiar shapes, even at angles of up to 90 degrees. Therefore, pruning to achieve the desired shape is advantageous.

Additionally, you may want to explore the Dwarf Barbados cherry, a miniature cherry variety ideal for container cultivation, with cascading growth habit. Although its fruits are slightly smaller than those of the regular variety, they are notably sweeter.

When it comes to ensuring the health and vitality of your potted Barbados cherry plants, maintaining a consistent nutrient supply is crucial. Implementing a regular fertilization regimen is essential to promote robust growth, consistent flowering, and bountiful fruit production. For optimal results, we recommend using Sunshine Boosters, which are specially formulated to enhance the development of fruits and edibles. These boosters are derived from organic amino acids, making them environmentally friendly and safe for year-round use. By incorporating Sunshine Boosters C-Cibus into your plant care routine, you can ensure that your container-grown Barbados cherry plants receive the essential nutrients they need to thrive and flourish.
