NOTE: The terms Hong Kong orchid tree and Bauhinia blakeana are identical in this text; in reality, Bauhinia blakeana is Hong Kong orchid tree’s biological word.
The Hong Kong orchid tree is a very striking specimen that can be planted in warm, arid climates. The shape and colors of the flowers are very similar to orchids. The official tree of the island is the tree that was discovered by French missionaries on the western coast of Hong Kong. These beautiful tropical trees are often referred to as evergreens, but in reality they are deciduous and drop their leaves in late winter before forming spring buds.
They have large butterfly-shaped leaves, and produce large, delicate-looking but sturdy blooms in shades of purple and rose pink, sometimes with some white variegation. At 6 inches across, the blooms are twice the size of other orchid tree flowers. At a time when there aren’t many trees flowering in the winter, the flowers of the Hong Kong orchid tree last from November through the end of March.
Why does my Bauhinia blakeana roots have rot?
If left untreated, root rot on your Hong Kong orchid tree (Bauhinia blakeana) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Hong Kong orchid tree have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Bauhinia blakeana being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.
Why does my Hong Kong orchid tree have leaf spots?
This type of disease is one of the most frustrating for Hong Kong orchid tree owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my Hong Kong orchid tree leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Each deficiency produces a different yellowing on the Bauhinia blakeana in question, here’s how to spot them:
- Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my Hong Kong orchid tree sunburned?
It is simple to determine whether your Hong Kong orchid tree (your Bauhinia blakeana) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, if your Hong Kong orchid tree receives too much water or not enough light, the leaves may also change color.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.
Why are my Hong Kong orchid tree leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Bauhinia blakeana in direct sunlight?
No! Don’t leave your Bauhinia blakeana (or Hong Kong orchid tree) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
The remedy, as said in the paragraph above, is simple: just move your plant’s Hong Kong orchid tree out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Bauhinia blakeana leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
An easy way to know if your Bauhinia blakeana is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Hong Kong orchid tree right after a dry period thinking that it needs a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Bauhinia blakeana
Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.
The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.
Always keep temperatures stable
It’s also a good idea to keep your Bauhinia blakeana at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Bauhinia blakeana away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Hong Kong orchid tree Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
For your Hong Kong orchid tree, this would be a true descent into hell, and it would also appease the pests.
To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
