Growing tropical fruit trees in containers in winter

Q: Please give me your advice. The winter is here. I bought mango tree, jackfruit tree, sugar apple tree and planned them for spring. What can I do to keep them no frost bite? My home in Bonifay FL.

A: In subtropical areas with occasional hard freeze in winter, we recommend you to keep tropical plants in pots. The plants you purchase are tender to frost. For cold protection, container growing has several advantages:
1) easy to move into wind-protected and sun-exposed locations as needed: for example, on a different side of the house. In many areas, seasonal prevailing winds have opposite directions in Summer and Winter.
2) easy to cover with frost cloth, sheets, or blankets in case of immediate cold spells. Container plants' growth is easier to control and trim, and those plants naturally stay more compact.
3) easy to move indoors, inside garage, or in covered lanai/patio.
We also recommend to keep these trees in their original pots until Spring, in containers size of the rootball. Step them up in Spring, when plants start active growth of root system. This will help you to avoid root rot due to possible overwatering in Winter. Reduce watering in any case, and keep your plants in bright, wind-protected spot. Do not fertilize until Spring. Protect from cold when night temperature drops below 35-40F.

Use SUNSHINE plant boosters to provide additional cold tolerance.

Cold protection is a lengthy subject. You may also use propane heaters during cold nights. Here is some more information on cold protection.

Desert rose winter care

Q: I purchased several packets of desert rose seeds last year. I now have 45 very healthy seedlings some of them in bud. Almost all of my seeds grew but I lost most of them when I rook them in during winter. I did not water them for a month , kept them in their pots and set them by the window. they either dried up and died or rotted and died. I noticed when you send me grafted specimens that you bareroot them. Is this a better way to keep them inside in winter, bareroot? I hate to lose these plants come winter time. Pls advise me. I live in Houston, Tx. where we get temps below 40 degrees and sometime a day or more of freezing temps.

A: Thank you for your question. Rot is pretty common problem with Desert Roses. We monitor our Adeniums closely and have a special set up of watering environment and schedule, in dedicated greenhouses just for them. Nevertheless - every now and then we see a rotten caudex and can't help it to say "oops! over-watered!" These plants are very sensitive to environment changes, especially when it comes to a combination of water and temperature. These are a few tips that should help you to reduce risk of plant loss to a minimum:

1) Use only well drained mix with much higher content of perlite than you would use for most tropical plants. For adeniums, we use mix with 30-40% of perlite in it, while regular mix has 10-15%.

2) Adeniums like alkaline soil, unlike most of tropical plants (hard to say what else likes alkaline... Ficus for sure!). This means, regular mix with high content of peat moss may cause root rot. To increase alkalinity, you may add dolomite. Here in Florida where we have natural supply of shell rock handy, it is easy to add some shell to a potting mix (shell sand, rather than quartz sand). We always add a few large shells on top of a pots with a big specimen. Besides increasing soil pH (making it more alkaline), shells look very decorative.

3) Water very carefully during cooler months. When it is hot (85-100F), excessive water usually won't harm adeniums: it will be partially used by a plant, and partially will evaporate. Especially be careful with water when temperatures drop below 65F - then tropical plants simply stop growing process and go dormant. Once adeniums start losing leaves, this is a sign to reduce watering to once a week to once a month, and in very small quantity (couple tablespoons per pot).

4) We do not bareroot adeniums for winter storage. They are not bulbs. Barerooting of this plant is recommended only during shipping. Adeniums can stay without soil for up to a week without hardly any stress, sometimes even longer.

5) We keep our big collection specimens on a roofed porch during winter, where level of light is very low. Last winter we haven't lost a single plant due to low light. They take shade pretty well considering minimum or no water. However bright light is always better - it creates healthier environment for a plant. We all know about space limitations for our large collections, especially in winter. So if you can afford a bright spot for adenium during winter - the plant will be lucky!

Spring time fun: fertilizing and pruning

Q: When is a proper time to start fertilizing my garden in Spring? Also, when can I cut back cold damaged branches? Should I wait until end of April?

A: As a rule of thumb, fertilizer can be applied during period of active growth, when a plant needs additional nutrients. With indoor plants, you can fertilize pretty much year round as long as the plant continues growing and not dormant. For in-ground tropical plants, start fertilizing when new growth appears. In subtropical areas, with cooler winter months, most tropical plants slow down their metabolism when temperature drops below 65F. Many of them become dormant, and may even lose leaves (especially deciduous plants like Annona, or Peaches/Plums). In spring, tropical plants wake up as soon as outside temperature stays above 65F for at least one week (including night time). Once you see new growth, this is a signal for you to start fertilizing.

As far as trimming dead branches - wait until you see new leaves completely opened up. This way you won't cut too much, as some parts of the plant may take longer to re-leaf than others.

🌱 💪 Green Magic + SUNSHINE Boosters: A Complete System for Strong Plant Growth

By Tatiana Anderson, Horticulture Expert at Top Tropicals with Smokey & Sunshine help

Nearly  dead  houseplants  (Dracaena,  Syngonium,  and  Spathiphyllum) 
 recovering  and  growing  vigorously  after  treatment  with  Green  Magic 
 fertilizer  and  Sunshine  Robusta  plant 
 booster.

Green Magic recovery test with SUNSHINE Robusta support: Dracaena, Syngonium, and Spathiphyllum revived from severe stress and growing vigorously.

☀️🌱 Sunshine Boosters: Complete Plant Nutrition

Sunshine Boosters provide complete plant nutrition, including Calcium and micronutrients that plants need for strong growth. Because nutrients are delivered in liquid form, plants can absorb them quickly and respond almost immediately.

The Practical Problem

Liquid feeding works well, but it requires frequent application. In real gardens, many growers simply do not have time to add liquid fertilizer with every watering.

Green Magic: The Foundation

Green Magic solves this problem by providing steady background nutrition through controlled-release fertilizer. It feeds plants gradually, so they continue receiving nutrients even between liquid feedings.

Why This Combination Works

Together, this system provides both complete nutrition and steady feeding. Sunshine Boosters supply fast nutrients and Calcium, while Green Magic maintains a stable nutrient supply between feedings.

✍️ How to Feed Your Plants

📅 Step 1 – Start of the Growing Season

  • Apply Green Magic around the root zone every 6 months.

    In ground:
    • Small Shrubs (1–3 feet): Use approximately 1/4 to 1/2 cup per plant
    • Established Trees: Use 1/2 lb to 1 lb of product per 1 inch of trunk diameter.
    • Small In-Ground Ornamentals: A common "spoon" rate is roughly 1 teaspoon per gallon of estimated root volume (or per sq. ft. of surface area).
    • Spread evenly around the dripline. Avoid piling the granules against the base or trunk of the plant. For best results, lightly rake the granules into the top 1–2 inches of soil.
    Container plants:
    • Apply 1 tea spoon per 1 gal of soil (mix in with soil) every 6 months during active growth period, or with every re-potting.
  • Water normally after application.
  • Adjustment for Temperature. Because Green Magic is temperature-controlled, adjust your rate if your local climate is extreme:
    • Cooler Climates (<60°F average): Increase the rate by 20% to ensure enough nutrients are released.
    • Hot Climates (> 80°F average): Decrease the rate by 20% to prevent over-releasing as the heat speeds up the process.

☀️🌿 Step 2 – Active Growing Season

  • Apply Sunshine Boosters during the growing season.
  • Regular feeding (maintenance): Mix with tap water according to the ratio on the label. For SUNSHINE Robusta use 25 ml (5 tsp)per gallon of water and spray leaves every 5-7 days during active growth.
  • Correction feeding ("medicine" dose): if plants show visible nutrient deficiencies, combine SUNSHINE Robusta with SUNSHINE Superfood and spray every 5–7 days until new growth appears healthy. All SUNSHINE Boosters products are compatible and can be mixed with water in the same sprayer.
  • Best time to spray: early morning or evening when temperatures are cooler and leaves can absorb nutrients efficiently.
  • Important: spray both the top and underside of leaves for maximum absorption.

❓Frequently Asked Questions: Plant Nutrition & Fertilizer

General Fertilizer Concepts

Why is the "Spring Fertilizer Rush" a problem?
Most gardeners apply a large amount of traditional fertilizer once in March. This creates a "roller coaster" effect where plants get a sudden spike of nutrients followed by weeks of starvation. This leads to inconsistent growth and potential "fertilizer burn."

What is "fertilizer burn"?
Traditional fertilizers are made of soluble salts. When too many salts accumulate around the roots, they actually pull water out of the plant tissues (osmosis), dehydrating the plant and damaging sensitive root tips and leaf edges.

Is there a difference between "Slow-Release" and "Controlled-Release"?
Yes.

  • Slow-Release: Relies on natural factors like moisture and soil microbes to break down. It is often unpredictable.
  • Controlled-Release: Uses engineered polymer membranes (like Polyon) to release nutrients at a specific, predictable rate based primarily on temperature.

Green Magic & Temperature

How does temperature affect my fertilizer?
Most fertilizers are lab-tested at 75°F. In hot climates (90°F+), the nutrients release much faster. A "6-month" fertilizer might only last 3 months in the summer heat.

How should I adjust Green Magic for my local weather?

  • Cooler Climates (<60°F): Increase the application rate by 20%.
  • Hot Climates (> 80°F): Decrease the application rate by 20% to prevent over-releasing.

The Calcium Gap

Why doesn't Green Magic contain Calcium?
Calcium salts are highly soluble and can destabilize the polymer coating used in controlled-release granules. Therefore, most high-quality granules leave Calcium out. You can provide Calcium by using SUNSHINE Boosters

Why is Calcium so important for new growth?
Calcium is the "bone" of the plant, building strong cell walls. Unlike other nutrients, it is immobile—the plant cannot move it from old leaves to new ones. If you don't provide a constant supply, new leaves and fruit will emerge distorted or weak.

Advanced Science & Troubleshooting

What makes Sunshine Boosters "Bioavailable"?
Unlike most liquid fertilizers that use EDTA chelators, Sunshine Boosters are amino-acid based. They use organic acids and glycine to escort minerals into the plant, allowing it to incorporate nutrients into its proteins almost immediately.

Will these fertilizers affect the taste of my fruit?
No. Sunshine Boosters are made from pharmaceutical-grade components and contain no urea or harmful salts, ensuring your harvest (like Mangoes or Avocados) has a pure, natural flavor without a chemical aftertaste.
