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.

Seeds germination in summer

Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?

A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:

- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.

- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.

- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4"diameter).

- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.

- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.

- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.

- Do not overwater young seedlings, keep soil slightly moist but not soggy.

SUNSHINE Boosters: The Professional Advantage

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

Sunshine  Boosters  plant  fertilizers  lineup  including  Bloom,  Pikake, 
 Robusta,  Omnibus,  Ananas,  Mango  Tango,  Citrus,  and  MegaFlor

Sunshine Boosters for different types of plants

Here is why SUNSHINE Boosters are the smart choice for your garden this spring:

  • Amino Acid Stability: Unlike traditional fertilizers that use synthetic EDTA chelators, our formulas are amino-acid based. This means 100% of the nutrients are bioavailable and consumed by the plant, leaving zero toxic residues or salt build-up in your soil.
  • Safe for Every Watering: Because our concentrations are scientifically balanced and mild, they are safe for daily use. This eliminates the "feast or famine" cycle of dry fertilizers and prevents accidental root burn.
  • Pure Taste for Edibles: Our delicate formulas do not contain excess salts, urea, or ammonium salts that can ruin the flavor of your harvest. Your fruit and vegetables will retain their pure, natural taste.
  • Pollinator Friendly: Our boosters are designed to be safe for honeybees and other beneficial insects, making them the responsible choice for an organic-style garden.

🌿For Potted Plants: Breaking the "Foodless" Cycle

Container-grown plants are trapped in soilless mixes (peat, bark, perlite) that are structurally great but naturally nutrient-deficient.

  • Total Nutrition: Since pots lack the natural "buffet" of the ground, SUNSHINE Boosters™ provide every essential mineral the plant cannot find on its own.
  • No Salt Build-up: Our amino-acid based formulas are consumed entirely by the plant, leaving zero toxic residue or root-burning salts behind.
  • Daily Safety: Our mild concentrations eliminate the "feast or famine" cycle of dry fertilizers, making them safe for use with every single watering.

For In-Ground Plants: Unlocking the Soil

 Booster

Even in the ground, plants often struggle to absorb what they need because soil compounds can "lock up" nutrients.

  • Enhanced Solubility: SUNSHINE Boosters create a slightly acidic environment that helps dissolve stubborn salts in the soil, making them accessible to roots again.
  • Precision Delivery: We provide mobile elements like Nitrogen precisely when the plant needs to push new spring growth.

🌿The Foliar Advantage: Direct-to-Leaf Delivery

Did you know a plant leaf can absorb nutrients even more efficiently than the roots? Foliar feeding is your "emergency button" for instant results.

  • Quick Fix: Foliar applications with Sunshine Superfood are the fastest way to correct yellowing leaves or visible deficiencies.
  • Metabolism Boost: Sprays like SUNSHINE-Epi act as a bio-regulator, helping plants recover from the stress of spring temperature swings.
  • Better Fruit: SUNSHINE Honey is applied to leaves to naturally move sugars to the fruit, increasing sweetness and flavor.

🌿The Calcium Problem: Solved

As your plants wake up this Spring, they need structural strength. Think of Calcium as the "cement" that holds plant cells together. Without it, new spring growth is doomed to fail.

Signs Your Plant is Starving for Calcium:

  • Deformed Leaves: New growth looks twisted, hooked, or curled.
  • Blackened Tips: The very edges of young leaves turn white, then quickly blacken and die.

The Industry Secret: The "Missing" Mineral

Most fertilizers, both dry and liquid, completely skip Calcium. Why? Because it’s a chemical nightmare to keep stable in a concentrated solution. Most manufacturers rely on your irrigation water to deliver Calcium, but tap water is inconsistent and often fails to provide what a hungry, growing plant needs.

The SUNSHINE Boosters: Stable Calcium in Every Bottle

We have successfully stabilized Calcium directly into every single Sunshine Booster formula. Whether you are using Bombino, Robusta, or Megaflor, you are delivering a precise, stable dose of Calcium with every watering. No lockout, no sediment, and no relying on the "luck" of your tap water. Just strong, healthy cell walls and perfect spring growth.

🌿SUNSHINE-Epi: The Year-Round Bio-Regulator

Whether it’s the transition of spring, the extreme heat of summer, or the dry air of indoor wintering, SUNSHINE-Epi is your plant’s primary defense. This natural Brassinosteroid acts as a powerful immune booster, helping plants navigate stress wherever it comes from.

  • Universal Stress Shield: Protects against temperature swings (both heat and cold), drought, and transplant shock.
  • Vigorous Development: Dramatically improves root growth and speeds up the metabolism of young seedlings and cuttings.
  • Eco-Safe: 100% non-toxic to humans, pets, and pollinators.

Note: While Epi is highly effective, it is a performance booster, not a substitute for proper care. It works best when paired with the right light, water, and a consistent feeding program. It won't bring a dead plant back to life, but it will help a struggling one find its footing.

❓Frequently Asked Questions: SUNSHINE Boosters™

  • What water should I use for foliar spraying?
    Tap water works perfectly for most. However, if your water is very "hard" (leaving white mineral spots on leaves), switch to distilled water for a cleaner finish and better absorption.
  • How long does a diluted solution last?
    For maximum potency and to avoid nutrient degradation, try to use your diluted mixture within a few hours of preparation. Keep away from direct sun. Fresh is always best!
  • Can I use SUNSHINE Boosters as a daily foliar spray?
    Yes! You can mist your plants daily to maintain high vigor, but you must reduce the dosage (use half the recommended strength) to avoid over-feeding.
  • Can I mix boosters with pesticides or fungicides?
    It is best to apply them separately. Mixing fertilizers with chemical pesticides in one tank can trigger reactions that "lock out" nutrients or reduce the efficacy of the treatment.
  • Will the liquid stain my patio or hands?
    No. Unlike traditional fertilizers with heavy blue or pink dyes, our solutions are clear or very light-colored. If you spill it, simply rinse with water—no stains, no mess.
  • Can I mix different SUNSHINE Boosters together in one sprayer?
    Yes. All SUNSHINE Boosters are chemically compatible. You can combine a "growth" booster like Robusta with a "micro-element" complex like Superfood in the same water to save time.
  • Are these products safe to use around my pets?
    Absolutely. Our formulas are 100% non-toxic and amino-acid based. Just ask Smokey and Sunshine—they are perfectly safe for households with curious cats, dogs, and children.
  • Can I use these boosters on indoor plants?
    Yes. They are ideal for indoor use because they don't produce a "fertilizer smell" and won't cause salt crusting on your decorative pots or furniture.
  • Is it safe to use on fruit and vegetables I plan to eat?
    Yes. Because our formulas contain no urea, nitrates, or harsh salts, they don't leave a "chemical" aftertaste. They actually help improve the natural sugars and flavor profile of your harvest.
  • What is the best temperature for foliar spraying?
    Apply when temperatures are below 85°F. Early morning or late evening is best; this allows the leaves to remain wet longer, giving the plant more time to absorb the nutrients.

What Fertilizer to Use and How?

Green Magic controlled release fertilizer keeps plants green during active growth season - apply only once in 6 months.
Sunshine: Smokey, you saved my coffee tree. But what do I do now so it stays happy?

Smokey: Simple. Spray Sunshine Robusta every five days during active growth.

Sunshine: Five days? Smokey, I barely remember where I left my coffee mug five minutes ago.

Smokey: That is exactly why we use Green Magic.

Sunshine: Fertilizer for forgetful gardeners?

Smokey: Controlled release. Sprinkle once and it feeds the plant for six months.

Sunshine: Six months? I can have a very good nap in that time.

Smokey: Exactly. The plant keeps eating slowly while you keep napping.

Sunshine: Perfect. Remember, I will bring the coffee. You bring the donuts.

Smokey: And next week we will show you exactly how Green Magic works and why plants love it. Stay tuned.

When the forecast drops into the 30s, panic is not a plan. This is your simple, clear checklist to protect every tropical in your garden. Think of it as the quick emergency manual that goes hand in hand with the previous cold-weather newsletter.

"We all love our tropical flowers, mangoes, bananas, and rare fruit trees. A single cold night does not have to be a disaster. The key is knowing what to do, when to do it, and what mistakes to avoid." - Tatiana Anderson, Top Tropicals Plant Expert

🌡️ FROST AND FREEZE

A frost and a freeze are not the same. A frost is when you see ice crystals on leaves or grass, while a freeze is when the air temperature drops below 32 F. The tricky part is that you can get frost even when the air is above freezing, and you can have a freeze with no frost at all. It all depends on humidity and the dew point. If the dew point is below freezing, the ground can cool faster than the air, letting frost form even when your thermometer reads 35 or 36 F. And once the air itself drops below 32 F, even for an hour, tender tropicals can be damaged. For plants, a freeze is far more dangerous, because freezing air pulls heat out of stems, branches, and roots. Frost usually burns leaves, but a true freeze can injure wood, kill buds, and damage the entire plant.

WHAT TO DO AND NOT TO DO BEFORE A COLD SNAP

✔️ 5 THINGS TO DO:

  1. Water well. Hydrated plants tolerate cold better than dry, stressed ones.
  2. Add mulch. A thick layer around the base keeps roots warm.
  3. Block the wind. Move pots to a sheltered corner or patio.
  4. Cover at night, uncover in the morning. Let plants breathe and get light.
  5. Add gentle heat if needed. Non-LED Christmas lights or a small old style 15-20W light can raise temps a few degrees.

❌ 5 THINGS NOT TO DO:

  1. Do not prune or trim. Fresh cuts freeze first.
  2. Do not overwater. Wet, cold soil invites root rot.
  3. Do not let plants dry out either. Wilted plants freeze more easily.
  4. Do not use dry fertilizer. Gentle liquid feeds like Sunshine Boosters are safe to use with every watering: its intake naturally slows down as watering decreases.
  5. Do not look only at the thermometer. A long, windy night can be worse than a short freeze.

TEMPERATURE ACTION GUIDE (40 to 25 F)

  • 40 to 38 F: Move potted plants to shelter, water soil, and cover tender tropicals.
  • 37 to 33 F: Use frost cloth and anchor it down so the wind does not lift it.
  • 32 to 30 F: Add a heat source like non-LED lights.
  • 29 to 25 F: Double-cover sensitive plants, wrap trunks, and protect roots heavily.

COLD TOLERANCE BY PLANT TYPE

Before a cold night, it really helps to know your plant’s exact cold limits. Every species is different, and young plants are always more sensitive than mature ones. Take a few minutes to look up your varieties in our Tropical Plants Encyclopedia — it will tell you the safe temperature range, how much protection each plant needs, and which ones must be covered or moved before the next cold snap hits.

  • Bananas: leaf burn below 37 F
  • Mango, Annona: hurt around 32 F
  • Cold hardy avocados: Mature tree can take about 25 F. Young trees must be protected
  • Olives, Citrus, Guava, Jaboticaba: usually OK outside with mulch

QUICK-ACTION TABLE

Before the cold arrives, make yourself a quick list of every plant and what action each one needs. It saves time when temperatures start dropping and keeps you from scrambling in the dark. Check that you have enough frost cloth, blankets, and supplies on hand so you can cover everything without rushing. Planning ahead makes cold nights much less stressful.

  • Bring Indoors: Cacao, Bilimbi, Coffee. They need warm, bright light.
  • Cover Outdoors: Mango, Jackfruit, Banana, Annona. Use frost cloth, not plastic on leaves.
  • Leave Outside: Eugenias, Peaches, Persimmons, Longan, Lychee, Papaya, Citrus, Loquat, Hardy Avocado. Add mulch and monitor overnight lows.

GADGETS AND TOOLS THAT HELP

  • Indoor helpers: LED lights, small heaters, bottom-heat mats, timers.
  • Outdoor helpers: frost cloth rolls, mini greenhouses, non-LED Christmas lights or small incandescent lights, smart thermometers.

Always keep electrical safety in mind, especially if you are using extension cords outdoors. Use only weather-rated cords, keep all connections off the ground, and protect plugs from moisture. Make sure heaters and lights are stable, secured, and never touching fabric covers. A few minutes of safety check can prevent a dangerous situation on a cold, wet night.

And if you want to keep plants strong through winter, add Sunshine Boosters to your watering routine. It is gentle, safe in cold weather, and gives plants an extra edge.

AFTER THE COLD PASSES

In the morning, uncover plants. Leaving covers on during the day can trap heat and cook the tender new growth, especially under the sun. The only exception is true frost cloth designed for all-day use, which allows air, light, and moisture to pass through. Regular blankets, sheets, and plastic must come off as soon as the sun rises.

Do not cut anything yet. A plant can look completely dead after a freeze, but many branches are still alive under the bark. Cutting too soon removes wood that would recover on its own. Wait until new growth begins in spring. That is when you can see exactly which branches are truly dead.

Use the scratch test. Gently scratch the bark with your nail or a small knife. If the layer underneath is green, the branch is alive. If it is brown and dry, it is likely dead. But even then, wait until warm weather to be sure, because sometimes only the tips die back while the lower part of the branch survives.

Once the weather stabilizes, resume light feeding. Plants coming out of cold stress need gentle support, not heavy fertilizer. A mild liquid feed like Sunshine Boosters helps them rebuild roots and push new growth without burning tender tissue.

WHAT NOT TO DO

  • Do not prune right after a freeze.
  • Do not overwater cold soil.
  • Do not fertilize heavily until spring.
  • Do not leave covers on in full sun.

CLOSING THOUGHT

Your tropical garden can survive any cold night if you prepare right. Cold snaps always feel stressful in the moment, but once you know your plants, have the right supplies, and follow a simple plan, it becomes routine. A few minutes of preparation before dark can save months of growth and keep your collection healthy all winter.

Frost cloth is the true workhorse of cold protection: it keeps heat in, keeps frost off, and will not suffocate plants the way plastic or blankets can. Having a few rolls ready means you never have to scramble at the last minute. Sunshine Boosters give your plants gentle support during the colder months so they stay strong enough to bounce back quickly when warm weather returns.

A little planning now will pay off in spring, when your mango, banana, citrus, and all your favorite tropicals come back happy and ready to grow.

❄️ How to overwinter tropical plants indoors



I have two Mandevillas that thrived on my balcony all summer. Now that cold weather is approaching, I've moved them indoors to bright spots, but they're dropping and wilting leaves. How can I keep them healthy until spring? Should I fertilize them? Can Mandevillas grow indoors year-round?

✔️ First, keep in mind that the plants we call "indoor plants" or "house plants" are all tropical. However, not all tropical plants are suitable for indoor living. Some, especially shade-loving ones, thrive in indoor conditions, which is why we refer to them as "house plants" (philodendrons, monsteras, calatheas, peperomias, and many others, including some succulents). Others are less adaptable to the lower light and humidity typical of indoor spaces, but with a little extra care, you can overwinter them inside and move them back outdoors in spring. Mandevillas are no exception! Even tropical trees, including fruit trees, can tolerate a few months indoors if given the right conditions for semi-dormancy. Below are the 10 key tips for successfully overwintering tropical plants indoors.
