The Hong Kong Orchid Tree

Bauhinia blakeana

"...Edging the golf course of the club was a glorious sweep of glowing purple. Even before I was near enough to identify the trees, the rich, heady perfume which filled the air told me they were Bauhinias. The sight left me breathless and it was then I realized how difficult was the attempt I was making to describe in mere words the trees I know better how to paint..." (D. Cowen, "Flowering trees and shrubs of India")

Bauhinia blakeana - Hong Kong Orchid Tree, is the most beautiful of all orchid trees, and the most wanted one. It has the largest flowers, brightly colored. Winter bloomer. These trees start flowering in very small size, when only 2-3 ft tall!
Certainly seeing flowering Bauhinia blakeana is one of the best things a plant collector will love about winter. It truly is the most beautiful orchid tree!

Planting during hot summer

Q: We just moved to Florida from New York. The weather is so hot and I wonder if I should wait till Fall to plant my garden? I tried to plant some seeds of annuals but nothing grew, just weeds. I also planted tomato seeds, they germinated but died in few days. What am I doing wrong?

A: Growing from seeds during hot season can be tricky. Here in Florida, we still can grow anuals and vegetables from seeds, but only during winter season. Annuals and tomatoes need cooler temperatures and protection from rain water which we have in abundance during summer. Combination hot + wet can kill those seedlings. On the other hand, seeds of tropical species love the heat and humidity, and germinate in no time, they just require a little experience.
However, Summer is a perfect time to plant and establish starter plants in your garden.

Five advantages of summer planting

1. Root growth. High temperatures promote rapid root growth - this is one secrets of a plant nursery. If you grow plants in pots, putting a pot on top of black ground cover will increase the effect, and the roots will grow even faster than the tops! This is a great head start for a plant. Make sure to provide adequate watering.
2. Fast development. With bright sun and longest day light, photosynthesis is more efficient. In simple words, during hot summer tropical plants have faster metabolism, they produce cells faster and grow leaves and stems faster.
3. Bugs be gone. Bright sun in combination with good air circulation will help to stay away from insects, leaf fungus, and other diseases.
4. Fertilizing can be generous and will be most efficient. In summer, there is less chance to overdose, as plant food is consumed fast, and summer rains help to prevent nutrient lock up in soil.
5. Rain water works like magic. Rainy season in Florida is our blessing. It can not be replaced by sprinklers or even daily hose water. Rain penetrates evenly and saturates not only a root ball but also the surrounding area that gives room to spread even bigger roots. Rain water also works like a "flush" to rinse off all excessive salts that may build up in soil.

Plant in summer and watch plants grow healthy and happy every day!

Growing Loquat in container

Q: I purchased a Sherry Loquat tree from you in April of 2020. It got off to a slow start initially, but now is five feet tall with healthy leaf growth! It is in a 15-gallon pot and was brought into the house by October 15th. I live in Zone 6 and kept the plant outside from end of May to October 15th. I have given the tree artificial lights in addition to slow release fertilizer. Can you please advise me on what steps I need to take to get the Sherry Loquat tree to fruit? E.g., lighting requirements, soil pH, soil type, etc.

A: Loquat is normally winter flowering and spring fruiting tree, here in Florida it is usually heavily covered with fruit by April. With a proper care, you may see flowers throughout the winter and they may set some fruit for you. Considering that during this time you have to keep the plant indoors, here are some recommendations:

1. Soil. Well-drained, porous potting mix. Do not use any heavy garden soils. For our plants we use the following mix which is excellent for containers: Abundance

2. Light. The brighter the better. Sunroom would be great, or at least put the tree next to a large window. Extra lighting with grow lights is beneficial. Any type of light will work, you can even use a simple clip-on light, the brighter the better. 8-10 hours a day.

3. Water. Loquat is drought tolerant but for fruiting it will need regular watering; just don't keep soil soggy, let is slightly dry before waterings.

4. Fertilizer program. Use liquid fertilizer. We recommend Sunshine Boosters that are safe to use with every watering and year around - SUNSHINE C-Cibus - Crop Nutrition Booster.
We recommend 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. Sunshine Boosters are scientifically balanced fertilizers that supply all necessary elements for daily plant needs. They are natural and eco-safe, great for any edibles.

5. Micro-elements. These are essential for potted plants, because in containers roots can't reach out to elements that are usually present in soil when trees grown in the ground.

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.

Trimming and treating Adeniums in winter

Q: My desert rose below dropped leaves after I replanted it in a bigger pot. I noticed that one of the branches that had been pruned is black at the tip. Please let me know if the section of the branch that turned black needs to be cut. I also wasn't sure how often to water it since the leaves have all dropped. None of the other dessert roses have dropped their leaves but they are all younger plants. Any advice would be much appreciated.

A: Your plant looks healthy and vigorous overall. Dropping leaves after repotting, or shipping, especially at this time of the year, is normal in Adeniums. They are deciduous and stay leafless from Fall to Spring. Some individual specimens can go into dormancy sooner than others - all depends on conditions: temperature, light, exposure, etc. and individual plant's "clock".
The black spot on the cut branch may be a sign of a fungus as a result of excess water. You may carefully clean/rub it with a paper tower dipped in Hydrogen Peroxide (pharmacy grade). Then rinse with fresh water.
Keep the plant warm and in a dry spot. Once leaves are dropped, it doesn't need much water. Once a week watering is enough.
