PeopleCats of TopTropicals. Cats of the day: Biggy's Cat Hospital

Biggy checking on patient Abu when he couldn't walk

During these challenging times for the whole planet, we receive kind letters from our customers checking on how our PeopleCats are doing, especially those that previously were ill. And since we promised to follow up on everyone, including heart-breaking story of Raja and Abu, today's report is about everybody's progress!

As we mentioned in our previous newsletter, several cats in TopTropicals Cat Sanctuary had a coronavirus (we call it COVID-Cat-20), or simply a cat respiratory infection. Chiefy, Snitch, Marco and Biggy had it really bad, but some other PeopleCats surprisingly didn't get it! Just like with humans. Lucky King didn't have a single sneeze!
Finally, everybody has recovered by now, but it has been a very stressful couple of weeks for us, considering limited vet availability at this stay-home time. On top of that, Lil S had an abscess and was also contained in a home hospital, away from flu-quarantined PeopleCats. Our homes become real cat hospitals!
We are thankful to our customers support, especially Silvia who made several donations for our PeopleCats, and also recommended antiseptic pads - those worked great for Lil S!
Abu and Raja's adventures were not over... After 2 weeks of seeing a vet treating their infections and injuries, they got worse... Then after a couple of weeks in another hospital (and a couple thousand more in bills) we were suggested to put them down as hopeless since they would never walk again... But Kristi did not want to believe it, she did not give up! The kittens heard her. They won. Today, they are all better, walking, jumping and playing!

Thank you Kristi!
Never give up hope!

Stay safe and healthy with your PeoplePets!

☀️ When tropical plant takes a Summer break

Tropical landscape

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.

Meet PeopleCats of TopTropicals. Charlie, the Indoor Hunter

Carlie was a kitty drop off with LadyBug, Rickie, and Purry.
Charlie is Jamie's baby. She has an attitude of a teenager, one minute she loves you and the next - wants nothing to do with you. Carlie stays with the inside PeopleCats, she says it's too big in the outside world for her and she gets scared. Carlie has a fun game (fun to her): she plays around 2:00 am in the morning, she loves to drag random items down the hall (socks, toys, shirts, even blankets) in her mouth MEOOOWWWING as loud as she can. She then sets the items down on her human's bedroom rug and waits for her human to say thank you. We're pretty sure her hunting instinct is off...

Check out and more Cat of the Day stories.

Cold protection of tropical container plants

Q: I am long time customer of yours, I live in San Diego California and while the summer and Fall temperatures are warm to mild, the winter temperatures dip to a point where some tropicals die off. We are experimenting with different variations of way to heat and insulate the pots we have the tropicals planted in as a way to keep them alive during the colder winter months. I was wondering if you knew of the ideal soil temperature for these tropical in order to look their best year round. All of the heaters we have installed have thermostats and temperature adjustments so we can now keep the soil anywhere between a range of between 65-75 degrees. Any advise you can provide would be greatly appreciated.

A: This is a very interesting concept you are working with. Indeed, keeping pots/roots warm, may help a lot! We've been experimenting with cold protection for a long time - for the above-ground plant parts. For sure keeping roots protected (even with a thick layer of mulch) will benefit tropical plants during winter. In case with container plants, this may help dramatically.
The guideline is, tropical plants slow down or stop their metabolism at 65F. As long as you can keep soil above that temperature - this should work great. Of course, the higher the better.
Optimum temperature for growing tropical plants in general - 70-85F. Above 90F, metabolism stops too, unless it's a heat tolerant, desert plant.
