🍴 Why my plant turned yellow? And why plants need Micronutrients? The answer is: they need Superfood!



Nothing is more disappointing than when your plant’s bright green leaves begin to turn yellow. Too often gardeners blame pests for these issues, but at the root of the problem is almost always a nutrient deficiency.

Plants need both macronutrients and micronutrients.
Macronutrients (nitrogen, phosphorus, and potassium) help plants grow big and strong.
Micronutrients (like iron, zinc, copper, and manganese) are just like vitamins, needed in small amounts but are just as important for plant health.

Why are micronutrients important?

  • 📌 They help plants with vital processes like making food (photosynthesis) and building strong roots.
  • 📌 Without enough micronutrients, plants can look weak, turn yellow, or grow poorly.


Why use Sunshine Superfood for micronutrients?

  • 📌 Effective and fast: plants get the right amount of micronutrients quickly and efficiently.
  • 📌 Balanced formula: your plants get everything they need in the right proportions.
  • 📌 Sunshine Superfood is the ultimate micro-element supplement that can fix all deficiencies.
  • 📌 Easy to apply - just mix with water and feed your plants.
  • 📌 The quick absorption helps prevent nutrient deficiencies.


👍 Even if your soil is lacking in certain micronutrients, Sunshine Superfood ensures your plants get exactly what they need.

How to make leaves green?

Q: I purchased several plants from you and they all arrived in great shape. The Wrightia is very large and vigorous but some leaves are yellowish. How can I improve that look? Any special fertilizer?

A: Wrightias are very showy and beautiful plants, although sometimes they are susceptible to leaf chlorosis which in other words is iron deficiency, especially during wet rainy weather. It is not harmful to the plant and can be corrected with microelement applications. Use Microelements once a week to correct the iron deficiency that usually goes away within a month. Then maintain plants health with monthly applications. It is beneficial to use microelements in combination with regular applications of health boosting fertilizer.

Recommended boosters and microelement supplements:

Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster
SUNSHINE SuperFood - plant booster
SUNSHINE-Greenleaf

How to grow Cerbera and make it flower

Q: I purchased Cerbera manghas - Enchanted Incense a year ago. As you see from the photo, it's doing great however, no blooms. I fertilize properly and very often and use worm castings for micronutrients. Yes it's not "your" fertilizer, but my plumerias, that are also in pots they are over 5 feet tall and blooming like crazy. I don't see any inflows coming on the Cerbera at all and it is hot and humid here in North Carolina, so it's happy but no sign of blooming. What is your advice?

A: Top Tropicals first brought Cerbera manghas into the US plant market a few years ago, it was recommended to us by our friend, plant taxonomist John Mood who visited Thailand, and among other exotic plants noted this fragrant beauty. Since then we've been successfully growing this plant, it has become one of everybody's favorites.

Generally speaking, Cerbera culture is very similar to Plumerias. These plants are closely related. So if you know how to grow Plumeria, you sure will succeed with Cerbera. Hot and sunny location, well-drained mix, moderate water and bloom boom fertilizer will do the trick. However, we have noticed a few distinctive features that make this plant somewhat challenging at times.

1) Flowers

For past years, we've been studying what triggers its flowering. Sometimes these plants start flowering in 1 gal pot, 1 ft tall. Other times a large developed tree 5-6 ft tall, in 5-7 gal pot, grows beautiful foliage with no signs of flowers. Eventually all of them bloom, no matter how stubborn they are, it's just some individual plants start flowering sooner than others, all grown in the same conditions.
One of our plants in the ground, a well-branched tree, was covered with flowers for a few months, but only on the 3d year after planting. Before that, it only produced a few random blooms. Others bloomed in pots at very young age.
The following factors benefit to Cerbera flowering:
- full sun at least 10 hours a day
- hot temperatures above 85F
- regular water but not heavy rains
- regular fertilizer - Bloom Booster type
- very good drainage and drying out before waterings. If root ball stays moist, the plant may look healthy but won't set flower buds. Keeping on a dry side will encourage flowering. Very similar to Jasmines: they bloom like crazy in April while it's hot and dry in Florida, but once our summer rainy season starts, they reduce blooming.

We highly recommend using Sunshine Megaflor bloom booster or SUNSHINE Pikake in combination with micro-element supplements Sunshine Honey (B-Mo) and Sunshine Superfood (complex micro) that induce flowering. Dry and granulated fertilizers may not supply exactly what a plant needs: certain elements that trigger flowering may be missing. Sunshine Boosters formulas are scientifically balanced, they contain precise amounts of nutrients needed for setting flowers. Besides, excessive salts from regular dry fertilizers create nutrient lock up that may retard plant metabolism; with liquid amino-acid based Sunshine boosters, plants consume the whole menu of elements without building them up in the soil.

2) Fruit

Fruit of Cerbera are very pretty and cover the tree after profuse flowering. To inexperienced eye they may look very much like small mango or avocado fruit - so make sure kids or visitors don't try to eat them! Cerbera seeds are extremely poisonous.

3) Leaves

If you ever grew Passiflora or Milkweed, you know how leaves can be eaten by caterpillars overnight. This may happen to Cerbera too, as we discovered. In Florida environment this exotic plant doesn't have natural predators for protection from certain insect species that may feed on it. So watch out and if noticed first signs of leaves damage - its time for insect control.
Other than that, Cerbera foliage is usually beautiful and colorful, here in Florida it looks much healthier than that of Plumerias often affected with rusty residue during high humidity months.

Hope this helps. The Cerbera fragrance is enchanting, it is worth the efforts and waiting!

SUNSHINE in a bottle - your help during winter

Q: I have been using your new plant hormone SUNSHINE for plants after shipping, and I must admit it does make a big difference! They recover right away. I order plants online very often, and usually it takes up to a week or more until they start showing new growth. After SUNSHINE treatments, they look fresh within a day or two. My question would be, for improving cold tolerance, what do you recommend? I live in Florida and it is still warm here, should I start spraying my garden now or should I wait until cold spells?

A: SUNSHINE is very effective plant stimulant that helps tropical plants survive different kinds of stress, including cold, heat, drought, low light, etc. At TopTropicals gardens and nursery, we have been using this hormone for many years to protect our plants from unfavorable conditions, and it saved us many rare tender species, and lots of money!
The sooner in Fall you start treatments, the better. Don't wait until cold spell. SUNSHINE works slowly and in very low doses. The mechanism is actually about boosting, building up the plant's own immune system. Low doses once a week, even every other week will work just fine, so you will need very little of the product. For less than $5 you can help expensive rare plants to go through winter painlessly. Recommended application is only 2.5 ml/1 gal of water, to spray every 1-2 weeks throughout winter period.

Start spraying your plants with SUNSHINE now, to help them survive short winter days, build up insect resistance (especially for plants indoors), and what is most important, to remain strong through lower temperatures. These are our suggestions:

- SUNSHINE-T - thermo-protection booster. It is specially formulated for winter protection of tropical plants. To improve cold hardiness even more, spray 1-2 days prior to cold with 5 ml/1 gal solution and after that, continue applications with 2.5 ml/1 gal solution every 10-15 days throughout winter period.
- For large plant collections, and in-ground gardens in subtropical areas, take advantage of very cost effective bulk items 50 ml and 100 ml bottles of SUNSHINE.
- Don't forget that SUNSHINE is only a stimulant, and not a plant food. While regular fertilizer should be avoided during winter months, it is always beneficial to apply microelements through foliar spray. During cooler period, chances of chlorosis increase, because at low temperatures iron is difficult so absorb by roots especially in moist soil, hence iron deficiency! Our new Iron supplement SUNSHINE-Super-Iron microelement booster will help to avoid yellowing leaves and to maintain your plants strong and healthy during slow growth period. Ultra-potent, highly absorbable iron mix, with chelated Iron with DTPA (instead of usual EDTA) that is better soluble in hard water and more effective for chlorosis. This mix contains both EDTA + DTPA chelated iron in higher concentration than regular micro-elements mixes.

10 best fruit trees to grow in Florida, collage

Q: We recently moved into our new home in Florida, and the property is a great size - 5 acres - but it currently has no trees, just a few palms. I'm looking to plant some productive fruit trees to start building our own Food Forest. What fruit trees would you recommend as a good starting point?

A: With five acres of space, you have a fantastic opportunity to create a fruitful garden that can provide for your family for many years to come. Below are our top recommendations for must-have, easy-to-grow fruit trees that thrive in Florida's climate, grow quickly, and start producing right away.

1. Mango Tree
