Growing Exotic Adeniums

Exotic varieties of Desert Roses. Adeniums have many spectacular hybrids. The basic culture is very similar to orchids. A small pot with excellent drainage is a must. Adeniums do not like both over-watering or drying-out. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.

To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Fertilizer requirement for swelling up trunks is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves. Adeniums need lots of light for heavy flowering.

Most hybrids and species start blooming in the spring when the conditions are warm and days get longer, and continue blooming through the fall and winter in warmer climates. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy.

Planting instructions for bare-rooted succulent plants. Position the plant in a pot, size of root system. Use only well-drained soil with high content of Perlite and/or sand (cactus mix can be used), water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it.

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.
2. Pruning. Keep it pruned and it will get bushy and produce more blooms.
3. Well-drained soil. Hibiscus likes regular watering but hates wet feet.
4. 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
2) Fertilize on regular basis, it's better dilute concentration and add food with every watering
3) 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!

Healthy Plants: Q&A from Mr Booster

Jasmine Grand Duke flowering

Q: Hey can you help me figure out why my jasmine grand duke supreme is not flowering? Ive had it for almost a year (in NY) and only had 1 flower bloom and that immediately turned brown and died. Since then no flowers have come. The leaves are green and healthy and its growing like crazy but not flowers. Please help me figure this out.

A: For profuse flowering, Jasmine sambac needs 2 things: bright light and special plant food. We have plenty of both here in Florida. If your grow this plant indoors in colder climate, get it to flowering can be a bit tricky.
Your plant grows well overall with lots of vegetative growth, this is a good sign, it means it's healthy, and not being overwatered which is one of the most common problems with Sambacs. You're doing a great job! This jasmine just needs more sun and fertilizer.
Make sure to keep it in the brightest spot of your home. The more hours of light, the better. When night temperatures stay above 65F, it is beneficial to bring the plant outside on a balcony, patio, or in a garden in full sun as a potted specimen (move to bright light gradually). You should give this Jasmine plenty of food with every watering. We recommend SUNSHINE Pikake - Fragrant Flower Booster. This is a natural fertilizer that can be applied to plants year round without risk of burning the roots or nutrient lock up in the soil. It provides all necessary elements for the flowering cycle - just add a bit into watering can, every time you water.

Sugar grains on leaves?

by Mark Hooten, the Garden Doc

Q: On my Stemmadenia tree I noticed tiny drops (like white sand grain or sugar crystals) and wonder if this is a disease or some kind of insect and what can I do about it?

A: Sometimes certain vigorously growing (mostly tropical) plants develop suspiciously-looking tiny "growths" mostly on the undersides of their leaves. Without strong magnification, they can be easily mistaken for mealy bugs, scale insects, or any number of parasitic disease vectors.
However, according to plant pathologists, these are actually harmless excretions actually exuded by the plants themselves. A chemical analysis of these tiny granules shows that they are nothing more than polysaccharides. Polysaccharides are basically complex chains of sugar/glucose molecules which are simply a production of all plants undergoing photosynthesis. Polysaccharides are at the beginning of the entire food-chain. These odd tiny sugar-grained nodules are actually only semi-crystalline complex sugars which certain plants have over manufactured and have had no choice but to excrete through their stomata (breathing pores).
I have personally observed Cecropia, Psychotria, Spondias (Hog Plum), and Guavas doing this... there are many others. Nothing to worry about, they are harmless, but if they bother you - wash them off with a hose water.
