Q: We just moved to Florida and I see these beautiful trees with large purple flowers. I was told these are Orchid trees, do you have them?

A: Bauhinias, commonly known as Orchid trees, are renowned for their captivating flowers and unique foliage. These trees typically grow to a moderate height of 15-25 feet with a spread of 10-15 feet, showcasing a rounded to vase-like shape. Thriving in hardiness zones 9-11, they exhibit resilience to heat and can withstand mild frost. There are over 300 species of Bauhinia, which are distributed in tropical and subtropical areas. These species vary in characteristics such as size, foliage, and flower color, contributing to the diversity and appeal of this genus. You can find them as trees, shrubs, and even vines.

Bauhinias are evergreen (in tropics) to semi-deciduous (in cooler climates), offering year-round beauty with intermittent blooming cycles. The peak bloom time varies depending on the species and location, often occurring in late winter to early spring, bedecking the tree with striking orchid-like flowers in hues ranging from white and pink to purple and red. The flowers boast delicate petals with intricate patterns, resembling the elegance of true orchids.

One of the distinguishing features of Bauhinia leaves is their unique bi-lobed or bilobed structure, which gives them a distinct appearance. The leaves are deeply divided, typically into two lobes or halves, hence the common name "Butterfly tree" due to their resemblance to butterfly wings. This characteristic is often used as an identifying trait for Bauhinia species. The bilobed leaves add to the visual appeal of the tree, contributing to its ornamental value in addition to its beautiful flowers.

Low-maintenance by nature, Bauhinias require minimal upkeep. Annual feeding with a balanced fertilizer enhances growth and flowering. Pruning is generally optional but can be done in late winter or spring, after flowering, to maintain shape or remove dead or damaged branches. These trees thrive in full sun, preferring well-drained soil. With their enchanting blooms and easy care requirements, Bauhinia orchid trees are a delightful addition to any landscape, and a colorful specimen for tropical winter gardens.

In addition, Orchid trees grow fast and provide excellent shade. They can make a shady spot in your garden in no time, giving relief from the hot sun. This is really valuable, especially in places where it gets very hot. So, not only are Orchid trees pretty to look at with their lovely flowers, but they're also great for keeping you cool!

Grow Your Own Food

Guava is one of the most popular and well-known tropical fruit because it is so tasty, sweet, juicy and flavorful! Many people are familiar with it because of the large number of products made from this aromatic fruit. But very few people know that Guava tree culture is very easy and this plant can fruit in a pot right away. Guava tree start blooming and producing fruit as small as 1 gal pot size. It can be kept in compact shape, responds well to pruning, stays bushy and grows very fast. It is a perfect container fruit tree or a specimen for a tropical garden of any size.
Upon ripening, the fruit becomes soft and juicy. It may be eaten fresh, made into a juice or nectar contain fruit pulp, or made into preserves, jam, jelly, or paste. A distinctive, savory-fresh aroma of fruit is thermo-stable, thus survives processing. The guava is an excellent source of vitamins C and A.
The plant is relatively cold hardy. Our young trees, 3 months after being planted in the ground were exposed to a short period of freeze last winter (mid-20's) but they grew back without significant damage. Try to keep Guava cold-protected for the first winter, then it will be much hardier once established.
Guavas are fast growers and heavy feeders, and benefit from regular applications of fertilizer. Make sure to get some Sunshine Boosters fertilizer: Sunshine C-Cibus - Crop Booster, and feed them your round.

How to get Canistel tree to produce
without dropping flowers and fruit

Q: My Canistel tree is 3 1/2 years old and is growing very well, see the picture below. It gets hundreds of pea sized "berries" but then they fall off. No canistel fruit. What's wrong?

A: You have such a nice looking tree, it is a shame you can't get any fruit to ripen.
In our experience, Pouteria trees dropping fruit prematurely is a very common problem. There may be one of the following reasons, or a combination of them:
- Cold winters may affect production, and while Canistel is generally pretty hardy tropical plant that can easily withstand short periods of chill, the fruit may never form properly if it had a cold winter.
- Lack of water. Canistel tree is pretty drought tolerant, but for the proper production cycle it needs regular irrigation. Especially during hot summer.
- The tree may be not strong enough; young trees drop fruit very often when they don't have enough "fruiting energy" built up in their system.
Your tree looks well established and vigorous, however, flower/fruit drop is often a sign of insufficient nutrients of particular kind, usually Boron (B) and/or Molybdenum (Mo): either when a tree is too young and not strong enough, or because of poor soils and lack of necessary elements.

Here is what can be done, considering you live in a warm, frost-free climate.

1. Provide regular fertilizing program. We recommend liquid fertilizers Sunshine Boosters that are safe to use with every watering and year around. It is beneficial to switch plants from traditional "slow-release" fertilizer to the liquid one because it makes a huge difference in plant growth and flower/fruit quality and quantity. See also:
- Why liquid fertilizers are better than dry
- Article about benefits of liquid fertilizers.

Use this plant food for your Canistel tree:
SUNSHINE C-Cibus - Crop Nutrition Booster

2. Apply micro-element remedies that are very effective for improving fruit production, especially when flower or fruit drop occurs:

SUNSHINE Honey - promotes more efficient blossoming and pollination, makes flowers bigger and reduces bud drop.
SUNSHINE SuperFood - improves plant vigor and quality and size of flowers These are all natural, eco-friendly supplements that work great for fruit trees and other edibles.

Fertilizing in Winter

Q: I have many tropical plants in my garden, both in the ground and in pots. I realize it is wintertime and some of them, the Hydrangea, Hibiscuses, and roses are in bloom but the rest of them seem wilty and droopy. Is it alright to fertilize them now, or should I wait for a few days? I have an all purpose tropical fertilizer and a 20-20-20 also. Please advise what to do.

A: During wintertime, tropicals may suffer from low temperatures and lack of sunshine which causes droopy leaves, and leaf loss.
Regardless of the cause and plant condition, you should NEVER apply traditional dry fertilizers during cool months. When cold, dry fertilizers (EDTA-chelated) may create nutrient lock up in soil and damage the roots. Dry fertilizers (both granulated and water-soluble) can be used only during hot season - when min temperatures stay above 65F for at least a week in a row, and daytime temperatures are over 75-80F. During hot, active growth season plant metabolism increases. This provides less chance for a chemical root burn, as the nutrients are used up quickly.

However, liquid fertilizers, as long as they are amino-acid based, can be used year round. From our own experience last winter, we discovered that fertilizing sickly looking plants (with signs of cold damage and root issues) with Sunshine Boosters actually revived those plants. Sunshine Boosters even brought back to life some hopeless specimens. Take a look at this gardenia that grows in our garden (picture above). See full article.
In your case, it would be beneficial to use a mild formula of liquid boosters in combination with Sunshine Epi -a natural plant hormone that boost their growth and helps to cope with cold-, temperature- and low-light-related stress.

These are the products we recommend:
- Sunshine Bombino - add to every watering
- Sunshine Epi - twice a month as foliage spray

Since you grow plants in pots, feeding program is especially essential, because plants are limited with a container size where roots can't reach out to more food in the outer soil. In professional nursery set up with injector irrigation systems, container plants are fed daily (depending on season, more than once a day) with every watering. This is why greenhouse plants are so healthy looking.
So feel free to give your plants Sunshine boosters with every watering, dozing according to the label. During cold period, plants need less frequent watering, so fertilizer input will be balanced accordingly, it will depend on temperature and plant metabolism.

Sunshine Bombino - mild, "pampering" formula for young and tender plants, as well as plants recovering from stress and/or winter damage.
