How to improve plant cold hardiness?

Pland cold hardiness depends on several factors, including:
1) genetics of specific species
2) maturity of the plant, size of root system, stems and branches
3) plant health and vigor which is supported by proper nutrition program and adding special plant hormones.

While 1) and 2) may be out of our control, the 3rd factor is something that can be easily improved! It is important to feed plants during the season of active growth on regular basis by applying macro- and micro- elements. Liquid fertilizers and especially natural plant food like Sunshine Boosters can be applied year around to keep plants healthy and strong.
Besides the routine fertilizing program, just a few applications of special plant hormones can increase tropical plant hardiness big time! Before the cold is coming, spray your plants with these 3 magic potions and they will gain a few degrees in low temperature tolerance! It is recommended to make 2-3 applications.

Why your plants might stop growing in mid-Summer
and what to do about it

Q: Why some tropical plants stop growing when it gets too hot? Aren't they supposed to like the heat? Should I use more fertilizer during hot Summer?

You've been watching your tropical tree thrive all spring. New leaves, steady growth, maybe even a flower or two. Then July hits, and… nothing. The heat cranks up, and your once-busy plant just sits there. No new shoots, no blooms, not even a twitch. If it feels like your plant ghosted you - but don't worry! It's not dying. It's just hot!

Q: What happens to tropical plants when it gets extremely hot?

When the heat hits, plants hit pause. In the peak of summer, especially with temperatures above 90F, many tropical and subtropical plants go into heat survival mode. Growth above ground may slow down or stop entirely. It's not because you forgot to water or skipped a fertilizer dose - it's just too hot. The plant's energy shifts underground, where roots may still be growing. Think of it like a tropical version of a siesta - less margarita, more mulch. This stage might last a few weeks or longer, depending on how intense the heat gets. But the important thing is: it's normal.

Q: What NOT to do?

  • Don't drown it in extra water. That leads to root rot.
  • Don't dump dry fertilizer on it. That can burn the roots or just get flushed away. Use controlled release or liquid fertilizer dozed proportionaly to the plant's water usage.
  • Don't prune aggressively, hoping to jolt it awake.

None of that helps - in fact, it can make things worse.

Q: What you CAN do?

  • Water deeply in the early morning, and let the soil dry a bit between waterings.
  • Add mulch to help keep the root zone cool and reduce evaporation.
  • Provide temporary shade for potted plants or young trees.
  • Hold off on pruning or heavy feeding until you see new growth.

Just like you wouldn't run a marathon in a heatwave, your plant needs a break too.

Q: Why you shouldn't fertilize stressed plants with dry fertilizer?

Fertilizing seems like the obvious solution when a plant stalls, but in the heat of summer, it can backfire. When temperatures soar, roots slow down, and absorption becomes inefficient. You might pour in nutrients, but your plant can't use them - and what's worse, any tender new growth that does emerge can get scorched or sunburned before it has a chance to harden.

Feeding a plant with strong fertilizers during a heatwave is like telling someone to sprint in a sauna. It's not just unhelpful - it's risky. That's why you need a fertilizer that’s engineered for hot weather - not just any slow-release formula.

Liquid Sunshine Boosters mild formulas are safe to use year around. Controlled release fertilizer like Green Magic are safe as well, just make sure to follow directions and dosage.


Q: Why Green Magic fertilizer works in heat better that Osmocote?

Green Magic controlled release fertilizer

Not all slow-release fertilizers are built for hot summer. Some popular brands might seem like a good choice - but they’re optimized for soil temperatures around 70-75F. That's a mild Spring day in the South, but in real-world Florida or Arizona heat? Not even close.

Here's the problem: Osmocote releases nutrients based on moisture, not temperature. When it's hot and humid - or worse, when you water heavily - it can dump too many nutrients at once. That nutrient surge can:

  • Burn your plant's roots
  • Force tender new growth that gets fried in the heat
  • Leach straight out of the pot, wasting both fertilizer and money

It's unpredictable, especially in containers that heat up faster than ground soil. What you think is "slow-release" can behave more like a fertilizer bomb.

Green-Magic, by contrast, uses a temperature-sensitive polyurethane coating that responds gradually and consistently as the soil warms. That means:

  • No sudden nutrient spikes
  • No wasted runoff
  • And no risk of heat-triggered burn

It's designed to feed steadily and predictably - even when temps hit 90F and stay there. For potted tropical plants, that kind of control is the difference between stressed and thriving.

Q: How does Sunshine Boosters help with daily plant recovery in summer?

Once your plant begins to show signs of life again - maybe a new bud, or evening perkiness - it's safe to resume feeding. But skip the salts, and reach for something gentler: Sunshine Boosters.

These amino-acid based liquid fertilizers are designed for daily use, even in containers during the hottest days. They enhance nutrient uptake, even when roots are stressed or sluggish. Unlike synthetic chelators like EDTA, Sunshine Boosters won't bind nutrients or burn root system. They stay gentle, available, and effective. Learn more from this short video.

Use SUNSHINE Robusta for foliage support, or Ca-Support PRO for strong structure and recovery. It's like hydration and nutrition in one - perfect for tropical plants fighting through summer heat.

Q: How can I help my plants during extreme heat?

Don't fight the heat - work with it. If your tree looks stalled this summer, don't panic. It's following a rhythm older than all of us. Support it with smart watering, the right fertilizer combo, and a little patience. Before long, you'll see buds again - and know your plant made it through the heat.

Q&A from Mr Booster

How to make Mango tree fruit

Q: Hello, I have a five-year-old Lemon Meringue tree that has only given me fruit one year. It put out about 50 mangoes and has done nothing for the past three years. Do you recommend any vitamins or any of the nutrients that you guys sell to help with this for next season?

A: We've had very similar problem with our Nam Doc Mai Mango tree, fruited once and no more next year. Usually the reason is nutrients deficiency, here in Florida we have poor soils. We applied Mango-Tango tree booster and it started flowering within a couple of weeks.
Generally, Mango flowering season is over by now, however, we recommend to feed the tree starting now, during active growth season. This way it will get better established before winter and also will store away all elements necessary for triggering flowering and fruiting. So by late Fall through Winter it will be ready to flower.
Along with the fertilizer, additional micro-element supplements will be beneficial. For improving fruit quality and increasing number of flowers, we also recommend to use SUNSHINE-Honey - sugar booster

SUNSHINE Mango Tango - Mango Tree Booster, for healthy mango trees and profuse fruit production.

SUNSHINE Honey - a natural supplements that makes fruit sweeter, and increases fruit quantity and quality.

🌞 Light

  • Bright, filtered light. Morning sun or dappled shade is perfect.
  • Avoid direct midday sun outdoors — it can scorch the leaves.
  • Indoors, place near a bright window with sheer curtains or use a grow light.

🌡️ Temperature

  • Warm and stable, ideally 70-85 F during the day.
  • Protect from cold drafts or sudden chills.
  • Ideally, do not let temperature drop below 45 F, although Taccas can tolerate short period of upper 30's.

💧 Watering

  • Keep soil evenly moist but not soggy.
  • Water when the top inch feels barely dry.
  • Use lukewarm water.
  • Avoid letting the pot sit in water.

💨 Humidity

  • High humidity (60-80%) is key.
  • Mist leaves often, use a humidity tray, or keep near a humidifier.
  • In greenhouses or bathrooms with a skylight, it thrives naturally.

🌱 Soil

  • Use rich, loose, well-draining mix
  • Combine bark, peat, and perlite for ideal airflow around the roots.
  • Best mix for growing tropical Tacca in pots - soilless potting mix Abundance . It provides perfect drainage and has a texture similar to a jungle rainforest media.

🍽️ Feeding

  • During growth season (Spring through Fall), feed with Green Magic controlled release fertilizer every 6 months. For even better results, you may apply liquid fertilizer Sunshine Boosters Rubusta.
  • Stop feeding dry fertilizer in cooler months when growth slows. Liquid Sunshine Boosters are safe to use with every watering, year around.

🏡 Indoor Growing

  • Great for bright bathrooms, sunrooms, or any warm, humid corner.
  • Rotate pot occasionally for even growth.
  • Keep away from heating vents and AC drafts.

🌴 Outdoor Growing (in warm climates)

  • Partial shade or filtered light under trees.
  • Excellent in large containers that can be brought inside for winter.
  • Shelter from heavy rain and wind.
