Meet PeopleCats of TopTropicals. Cat of the Day: Field Grown Marco

Marco loves growing plants and be involved in different projects outside. He is good at finding spots either on top, or inside some inappropriate objects. Yet simple boxes, that most cats find super comfy, do not interest him. Is has to be a plant container, saucer, or even a charcoal grill full of ash... He can sit in some weird places for hours like on top of a fence pole, or lay in the middle of a busy walking traffic while everybody have to step over or walk around him... We have quite a collection of Marco's special places and will be sharing with you!

How to get Jasmines to flower

Q: On the picture, these are a few of the jasmine plants that I have from Top Tropicals. I have bought so many plants from you over the years, not just jasmine. I have several varieties of jasmine. They were all doing very well. However this year I didn't get a single flower. There are a lot of buds... But before the buds open they become brown and withered. I bought fertilizer from you. Fertilized the plants once a month like I always do. I water the plants once a week. I repotted the plants hoping that would take care of this problem. Some of the jasmine plants I pruned... the plants came back vigorous growth with a lot of buds... BUT it is the same problem! Please help.

A: One of the possible reasons why they have flower issues is - maybe they don't have enough sunlight. They need to be in full sun all day long for profuse blooming and proper flower forming. However since the buds are forming, there may be just enough light. In this case, dropping buds may be a sign of overwatering.

Important steps - how to make Jasmine Sambac flower:

1. Soil. Use only well-drained soil

2. Water. Keep plants on a dry side and never over water. If the top of the soil is still moist, do not water.

3. Sun. Keep in full sun all day long. The more sun, the more flowers.

4. Bloom booster. Use Flower booster fertilizers:
Pink N Good Daily Plant Food - Flower Booster
Fragrant Plant Special booster, this 90-day Smart-Release container plant food:
Plumeria Top Dress - Smart-Release Booster
Do not use fertilizers with high Nitrogen (1st number in NPK formula) - those will promote more leaves instead of flowers.

5. Micro-elements. Use Apply micro-elements, they will help the plant to develop healthy and long-lasting flowers:
SUNSHINE SuperFood - plant booster

🌸 Plumeria Rust in Humid Climates:
What Finally Worked for Us

By Tatiana Anderson, Plant Expert, Top Tropicals

If you grow plumerias in Florida, you probably know what comes next. Around June, when the rainy season begins and afternoon thunderstorms become part of the daily routine, orange-yellow spots start appearing on the undersides of plumeria leaves. Plumeria rust arrives almost like clockwork. If you have ever tried to fight it, you know how frustrating that battle can be.

Let me be clear about something right away: Plumeria rust is rarely fatal to an otherwise healthy plant.

In our experience, we have never lost a healthy plumeria to rust alone. The disease is mostly cosmetic, but it causes significant yellowing, triggers premature leaf drop, and can turn a beautiful specimen into something that looks ragged throughout the best months of the growing season. For a plant grown as much for its attractive foliage as its spectacular flowers, that matters.

At Top Tropicals, we have grown plumerias for many years and have tried most of the approaches gardeners typically recommend: sulfur-based fungicides, neem oil, copper sprays, improving drainage, and removing infected leaves before they hit the ground. Some of those things helped to varying degrees. None of them felt like a real breakthrough until recently.

The Fungicide That Actually Did Something

A few seasons ago, on the recommendation of another grower, we tried Southern Ag Garden Friendly Fungicide . This biological fungicide contains the beneficial bacterium Bacillus sp, and I want to be careful here: I am not suggesting it is the best product for everyone or that it will produce the same results in every situation. What I can say is that, in our experience, it was the first fungicide that consistently produced visible improvement when applied according to the label directions.

We applied it at the first sign of rust, repeated applications according to the label, and actually saw the progression slow down while new infections became less severe. Whether that was the product, the timing, or some combination of factors, I cannot say with certainty. But after cycling through several options over the years, it was the one that felt like it was doing something real. If you are looking for a starting point, it is worth trying.

But the fungicide wasn't our main discovery. That came this past season, and it changed how we think about this disease.

☔️ What This Season Taught Us About Leaf Wetness

This season we moved our prized container plumerias under a covered growing area with a clear plastic roof and approximately 30 percent shade cloth overhead. The structure provides excellent light, warm temperatures, and very good air circulation while protecting the plants from Florida's frequent summer rains. It is not a climate-controlled greenhouse, but rather a protected outdoor growing area.

Here is the important part: these plants were still irrigated regularly, every two to four days, with overhead watering. The leaves did get wet. But because they were not sitting outside during Florida's daily summer downpours, the foliage dried within a reasonable amount of time instead of remaining wet for hours, which is common after a heavy rain followed by cloudy skies and still air.

The result? Not a single case of rust developed on those plants throughout the season. Considering how consistently plumeria rust appears each summer in our nursery, that result immediately caught our attention. The most significant difference was how long the foliage remained wet after watering or rain. Meanwhile, plumerias growing in the ground nearby, fully exposed to the weather, showed rust infection at the usual time.

💦 Ambient Humidity vs. Standing Water

That observation made us rethink what we believed was driving the disease. We had always assumed Florida's high humidity was the primary factor. Humidity certainly plays a role. But this experience suggested that prolonged leaf wetness may be a much more significant factor than ambient humidity by itself.

There is a real difference between air that feels humid and leaves that stay wet for four, six, or eight hours after a rain. Humid air means the moisture content of the atmosphere is high. Wet leaves means there is standing water on the leaf surface. Both conditions can occur together, but they are not the same thing. A leaf in a humid but breezy location can dry within an hour. A leaf in still, wet conditions after a heavy rain may stay wet most of the day. That difference may be far more important than many gardeners realize.

We are not plant pathologists, and we do not want to overstate what we learned from one growing season. But after many years of growing plumerias in Florida, the results were convincing enough that we now protect our best container specimens from prolonged summer rainfall whenever possible.

👉 What We Recommend

Based on many years of growing plumerias in Florida, here are the practices that have worked best for us:

• Grow plumerias in full sun whenever conditions allow. Good light means faster drying after rain or irrigation, and plants grown in low light often seem to show rust symptoms more readily.
• Keep your plumerias well-fed. Healthy, vigorously growing plants recover from stress and disease much better than weak ones. We apply Green Magic controlled-release fertilizer every six months for a steady supply of nutrients, and supplement with Sunshine Boosters Megaflor during the growing season. Because Megaflor is gentle, it can be safely applied with every watering, all year long.
• During extended rainy periods, consider moving valuable container plants under cover if possible. Even a covered patio can make a difference if it keeps the leaves from remaining wet for most of the day.
• Provide air circulation. Plants crowded together stay wet longer. Space them properly and position them where they receive good airflow.
• Remove infected fallen leaves. They can continue serving as a source of spores. Pick them up and dispose of them rather than leaving them beneath the plants.
• If rust begins to appear, start fungicide applications early. Slowing an infection at the beginning is much easier than trying to control one that is already well established.

💡 A Realistic Conclusion

Plumeria rust is mostly a cosmetic problem rather than a life-threatening one. Healthy plants usually recover well, but yellowing foliage and premature leaf drop can take much of the beauty out of an otherwise beautiful blooming season.

We cannot promise these methods will eliminate rust in every garden. Every growing environment is different. However, after years of battling this disease, reducing how long the leaves remain wet made a bigger difference than any other single change we have tried. If you grow plumerias in a humid climate and continue struggling with rust, it may be worth focusing not only on humidity itself, but also on how quickly the foliage dries after the rain stops.
