☀️ When tropical plant takes a Summer break

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?

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.
