Hibiscus: TopTropicals' first plant

- September 2001 @ TopTropicals -

Q: I wonder how you started your plant business and what was your first plant?

A: It was 20 years ago this month that we started Top Tropicals Project. No idea where it was going or how to even get "there", just started with the idea of sharing these wonderful creatures we call plants with anyone and everyone who felt the same way.

Believe it or not, the first plant at TopTropicals was a hibiscus. Right before we opened our plant nursery in Florida, we ran into a place called Winn Soldani's FANCY HIBISCUS. The variety of colors inspired us to start our own tropical plant business. We asked the owner Winn Soldani: what plants do you suggest us to grow in Florida? His answer was, "Your plant will find you". Very soon we discovered jasmines, then perfume trees and fruit trees - all those became our specialty. Then very quickly TopTropicals.com turned into a large Plant Mall where you can find every tropical plant you can think of!
But at TopTropicals we still grow hibiscus!

Hibiscus Plus

Hibiscus is a wonderful plant, considering there are thousands of hybrids with color palettes you can only imagine. Especially interesting are those rare and useful species, yet very easy to grow, such as:
- Salad Hibiscus - Hibiscus furcellatus - yes, used in salads
- Coral Hibiscus with crazy pendant flowers - Hibiscus schizopetalus
- African Cranberry hibiscus that is used for making teas and salads - Hibiscus acetocella
- Cotton Candy Hibiscus mutabilis - the flower changes color, opens as white and turns into bright pink within 3 days, like Yesterday-Today-Tomorrow

Care of Hibiscus and other flowering tropicals

"If your plant isn't flowering, feed it."
- Winn Soldani, Fancy Hibiscus -

Among gardeners, Hibiscus plants have a reputation to have couple maintenance issues:

1. they can get bugsy (because they must be so tasty!)
2. they can get leggy, especially fancy grafted cultivars, and after a while they don't look as perfect as when they came from a nursery.

   4 tips for healthy and pretty hibiscus plant

   1. Full sun. Essential for profuse flowering and keeps away diseases.

3. Pruning. Keep it pruned and it will get bushy and produce more blooms.
4. Well-drained soil. Hibiscus likes regular watering but hates wet feet.
5. Nutrition program. Hibiscus plants are heavy feeders. But keep in mind that if you just keep pushing granulated plant food, you can over-fertilize the plant. Excessive salts will accumulate in soil and you will end up with a sickly looking plant.

   Keys to balanced plant food and bloom booster

   1) Use liquid fertilizer, preferably amino acid based, it won't create nutrients lock up

6. Fertilize on regular basis, it's better dilute concentration and add food with every watering
7. Always add micro-elements - they are essential for plant health

   If you do this part right, the result will be:

- healthy, green plants, like they just came from a nursery
- reliable blooming circle
- better cold tolerance and disease resistance. Remember that a strong plant will be less stressed and less "bugged" by bugs!

We always suggest Sunshine Boosters - scientifically balanced liquid fertilizers that are amino acid based = they are natural and organic, can be used for both flowers and edibles, and what's most important - year around. They are safe to use virtually with every watering.

This is all you need for healthy plants and lots of flowers!

Fertilizer and the Fall Garden

by Ed Jones, the Booster Guy

...Well Labor Day has come and gone. Summer is winding down and depending on where you live, thoughts are now turning to pumpkin spice, witches, fall decor and gardening. Wait, did I just say gardening? Yes, if you live in the deep south, and I do, it is time to think about fall gardening and fertilizer. Even those of you in the north can put in a few quick crops now for fall. Think onions, radishes, lettuce and other greens and of course, garlic...

Next month, we can start putting out our plants that do better in cooler weather. We will put out some beans and of course cabbage. We may do some potatoes too. What do you like to grow?
But what about fertilizer? Glad you asked. Now, most of us have our favorite brand of fertilizer. Some of us had some secret fertilzers that we used in the past. For me it was composted alpaca manure. Yes, we raised alpacas in the north, but that is another story for another day....

...Once the temperatures have begun to drop, it is better to use a good liquid fertilizer. The one I will be using this year is SUNSHINE Robusta. SUNSHINE Robusta is an organic amino acid based liquid fertilizer that is safe to use with every watering. It uses amino acids to chelate (bind) micro-nutrients and makes it easier for plants to take them up from the soil. Most fertilizers use EDTA to chelate their micro-nutrients and plants must use about 4 times more energy to break them down than they do with SUNSHINE Boosters. This means that your plants will have more energy to put into growth. And isn't that what we are after?
With Special Seasonal price for 16 oz bottle reduced to only $19 with FREE shipping, this is your best choice of organic, safe fertilizer for your vegetable garden!..

How to fertilize herbs and vegetables

Q: We moved to Florida from New York earlier this year. My wife and I used to grow many fresh veggies and herbs in our garden up North during Summer, but it seems like in hot Florida the season for them is not until Fall. So we are preparing the beds and also looking for some organic fertilizer solutions. We've heard a lot about your natural Boosters and wonder if they can be used in our vegetable garden?

A: You came to the right place for organic fertilizer solution. Sunshine Boosters are based on organic amino-acids and are completely natural, non-toxic, eco-friendly, and do not build up nutrients in the soil. Their mild formulas designed specifically for edibles.
We just have started our own vegetable garden with some Biquinho and Wiri Wiri peppers, cherry tomatoes, and basil, and will be adding more as the the weather cools down.
For small scale gardens (both vegetables and herbs), you can start with Sunshine Robusta - a total feed "all on one". All necessary elements are provided in just one bottle, both macro- and micro-elements, it is a scientifically balanced formula. For larger gardens, especially if you have fertilizer injector system, we recommend Sunshine Boosters Pro Series - this product is much more economical, and you will need to mix only 3 solutions into your watering tank at the time of watering.
For more information, please contact our Booster guy Ed Jones, he can help you with selection and dosage information. Sample Discount program is available for samples of Sunshine Pro.

How to grow Cerbera and make it flower

Q: I purchased Cerbera manghas - Enchanted Incense a year ago. As you see from the photo, it's doing great however, no blooms. I fertilize properly and very often and use worm castings for micronutrients. Yes it's not "your" fertilizer, but my plumerias, that are also in pots they are over 5 feet tall and blooming like crazy. I don't see any inflows coming on the Cerbera at all and it is hot and humid here in North Carolina, so it's happy but no sign of blooming. What is your advice?

A: Top Tropicals first brought Cerbera manghas into the US plant market a few years ago, it was recommended to us by our friend, plant taxonomist John Mood who visited Thailand, and among other exotic plants noted this fragrant beauty. Since then we've been successfully growing this plant, it has become one of everybody's favorites.

Generally speaking, Cerbera culture is very similar to Plumerias. These plants are closely related. So if you know how to grow Plumeria, you sure will succeed with Cerbera. Hot and sunny location, well-drained mix, moderate water and bloom boom fertilizer will do the trick. However, we have noticed a few distinctive features that make this plant somewhat challenging at times.

1) Flowers

For past years, we've been studying what triggers its flowering. Sometimes these plants start flowering in 1 gal pot, 1 ft tall. Other times a large developed tree 5-6 ft tall, in 5-7 gal pot, grows beautiful foliage with no signs of flowers. Eventually all of them bloom, no matter how stubborn they are, it's just some individual plants start flowering sooner than others, all grown in the same conditions.
One of our plants in the ground, a well-branched tree, was covered with flowers for a few months, but only on the 3d year after planting. Before that, it only produced a few random blooms. Others bloomed in pots at very young age.
The following factors benefit to Cerbera flowering:
- full sun at least 10 hours a day
- hot temperatures above 85F
- regular water but not heavy rains
- regular fertilizer - Bloom Booster type
- very good drainage and drying out before waterings. If root ball stays moist, the plant may look healthy but won't set flower buds. Keeping on a dry side will encourage flowering. Very similar to Jasmines: they bloom like crazy in April while it's hot and dry in Florida, but once our summer rainy season starts, they reduce blooming.

We highly recommend using Sunshine Megaflor bloom booster or SUNSHINE Pikake in combination with micro-element supplements Sunshine Honey (B-Mo) and Sunshine Superfood (complex micro) that induce flowering. Dry and granulated fertilizers may not supply exactly what a plant needs: certain elements that trigger flowering may be missing. Sunshine Boosters formulas are scientifically balanced, they contain precise amounts of nutrients needed for setting flowers. Besides, excessive salts from regular dry fertilizers create nutrient lock up that may retard plant metabolism; with liquid amino-acid based Sunshine boosters, plants consume the whole menu of elements without building them up in the soil.

2) Fruit

Fruit of Cerbera are very pretty and cover the tree after profuse flowering. To inexperienced eye they may look very much like small mango or avocado fruit - so make sure kids or visitors don't try to eat them! Cerbera seeds are extremely poisonous.

3) Leaves

If you ever grew Passiflora or Milkweed, you know how leaves can be eaten by caterpillars overnight. This may happen to Cerbera too, as we discovered. In Florida environment this exotic plant doesn't have natural predators for protection from certain insect species that may feed on it. So watch out and if noticed first signs of leaves damage - its time for insect control.
Other than that, Cerbera foliage is usually beautiful and colorful, here in Florida it looks much healthier than that of Plumerias often affected with rusty residue during high humidity months.

Hope this helps. The Cerbera fragrance is enchanting, it is worth the efforts and waiting!

Care of Desert Roses

Q: I am looking forward to my three desert roses I just ordered from you and I am wondering how to take care of them, especially during winter time. Should I put the pots in full sun or shade? What kind of soil do they like? How often should I water them? When it gets cooler, should I bring them inside? We do have occasional frost here during winter.

A: Here are a few tips for your desert roses:

1. When received Adenium from mail-order, unpack carefully; branches are fragile. Plant in well-drained potting mix. Cactus mix will do, but we recommend special Adenium mix. If using regular acidic peat-based potting mix, you may add sea-shells on top of soil to neutralize acidity: adeniums prefer alkaline soils. Using clay pots is beneficial. Water once and do not water again until soil gets dry. Place in bright shade until new leaves sprout, then the plant can be moved to full sun.

2. Adenium is a succulent, but not a cactus. It needs watering, however let soil dry before waterings. Reduce watering during cool season and discontinue when plant gets dormant (drops all leaves in winter).

3. Bright light is the best for profuse flowering. However, adeniums look much healthier in slightly filtered light rather than in all-day full sun.

4. Fertilize and spray leaves with liquid fertilizer SUNSHINE Megaflor - Nutrition Bloom Booster. Phosphorous is responsible both for flowering and caudex development. Avoid caudex, spray over foliage only. Dry fertilizer can be used only during hot months.

5. Watch for spider mites during hot and dry season.

6. Give plants a break during winter dormant season. Keep in bright shade and reduce watering to 1-2 per month or stop watering if temperature is below 65F.

How to fertilize Caladiums and other Aroids

By Ed Jones, the Booster Guy

Q: I have a large collection of Aroid plants, different Monsteras, Philodendrons, and several unique varieties of Caladiums. I've been always told that Caladiums should not be fertilized, they don't like it. Is it so?

A: Caladium farmers often say that these plants don't need any additional fertilizer and that they really don't like it... The thing is, caladiums do not like DRY fertilizers, and this is why. Most Aroid plants do not like being watered too often, so dry fertilizers in combination with infrequent watering create excessive salinity for the root system. We have run some tests on the proper fertilizers for caladiums and the best results were performed after using SUNSHINE Robusta. It is amino acid based, so the delicate, large-leaved Aroid plants will not have to work quite so hard to take up the nutrients, and there will be no nutrient lock up in soil. The nutrients are readily available to these plants.
In this article, you will see some test results of caladiums fertilized with SUNSHINE Robusta vs. other brands of fertilizer, with more vigorous growth and larger leaf size occurring after use of Sunshine Robusta...

Caladiums do not have to be just an accent plant. They can also be the focus point of a garden area. It is said that as many as 98% of the world's caladium tubers come from right here in Highlands County, Florida, also home to the Sunshine Boosters manufacturing facility. It is such a big deal that they have a Caladium Festival here each summer. The fields are absolutely stunning in all of their colors. This year the festival runs this weekend, July 23 - July 25.

How to prevent mango flowers drop

Q:The mango blossoms my tree had in February have blown off due to weather conditions. Do you know what I can do to prevent this from happening again in the future?

A: The only "guarantee" to protect mango flowers from cold weather damage here in Florida is to plant a LATE flowering variety. Generally, mango trees are winter bloomers. Those varieties called "early season" start flowering in January (for example, Nam Doc Mai), and of course very often they get affected by cold, so they drop. Some varieties are so called "late season" - for example Venus. They start flowering in spring when the weather conditions are more favorable.
Another thing that may help you with mango flower drop is applying plant micro-element supplement Sunshine-Honey - it contains Molybdenum and Boron, which help flower and fruit development/strength and prevent their drop.

Growing Champaka in Virginia

Q: I purchased a Magnolia champaca 1 gallon a few years ago. It is still growing as I bring it into my greenhouse in the winter. I live in VA. This spring I planted it in the ground hoping it might bloom which it did not. Will it survive our fairly mild winters with several freezing days with some special attention? What would you do?

A: Magnolia champaca is a tropical tree and won't survive winter in VA. It can not take hard freeze. Your only option is, to keep it in a pot and bring inside. If the temperature inside your greenhouse is too low, this may affect the plant's ability to flower. For example, if it stays 35-40F for a whole month - although it is not a hard freeze and the plant may survive, but the duration of the cold period is more critical than the low temperature itself. Champaka can survive a few hours even at upper 20's, but not many days with cool temperatures. The temperature in winter should be maintained at least above 55F during day time (the higher the better) and at least above 45F at night.
If the tree has grown too big, you may trim it. If the root ball is too large, roots can be trimmed too (similar way like they do with bonsai) before repotting. However, trimming must be done either during warm season and active growth, or in Spring, when the tree starts waking up and promotes new growth.
To encourage flowering, start fertilizing your Champaka with a liquid bloom booster - SUNSHINE Pikake - Fragrant Flower Booster. It can be used year round including winter months, and it is safe to apply with every watering. This way you will provide to the tree enough energy for the next flowering season, so flowers can be expected in late Spring - Summer.

Tahitian Gardenia

Q: I am interested in your Tahitian Gardenia and I would love to try and grow this plant in a large container/fabric pot. The soil here where I live is terrible as it's hard rock, clay, and sand! So I'm not sure if amending the soil would help to plant in the ground? Can you tell me if this will do okay in a container or best in ground? I live here in Las Vegas, NV (zone 9a). Any information would be great to help me make a this decision, I love the selection of cool tropical plants you offer! Also my daughter does Tahitian/Polynesian dance and this would be a cool "topping on the cake" if she could have a live Tiare flower in her performances.

A: Tahitian Gardenia will be doing best if grown in container in your area. In its natural habitat, it grows full sun but also it enjoys mild weather conditions and high air humidity. All gardenias prefer acidic soils. In your area, if planted in the ground, it may be exposed to some harsh conditions: too high temperatures, too hot sun, dry air, and as you mentioned - heavy clay and sandy soil. You can enjoy this plant grown in container, which can be moved as needed away from too much sun during summer months. Use well-drained potting mix. Use plastic pot, do not use fabric or clay pots - soil will dry out too quickly.
Also remember to fertilize this plant on regular basis with a liquid fertilizer SUNSHINE Pikake - Fragrant Flower Booster.
Grow gardenia in full sun or semi-shade during the hottest months. You may spray it with pure water if the air too dry and hot. Enjoy your Tropical Beauty and good luck!
