Blush Pink Nandina(Heavenly Bamboo) is an ideal plant for beautifying the garden. They are on the favourite list of most gardeners for their frequent growing and low-maintenance nature. However, there are several issues that can harm your nandina plant, such as;
- Brown Spots on Leaf
- Yellow Ring
- Leaf Scorch
But no worries. In today’s article, I will discuss all these problems in detail and tell you about their easy solutions. So keep scrolling and stay with me.
4 Easy Ways to Fix Blush Pink Nandina Tree Problems
1. Brown Spots on Leaf
At first light brown spots are visible. Later the size of the spot increases as the colour darkens. Since the foliage of the Blush Pink Nandina plant has multicoloured shades, it is difficult to detect the leaf spot problem in its early stages.
- Excess Heat
First, the main cause must be identified. Take a good look at your leaves. If the leaves are drooping with brown spots and the undersides of the leaves are pale, this is due to excess heat. Nandina is a cold-loving plant so you need to maintain a temperature of 5°-10° F.
Leaf spot caused by a fungus usually does not clear up with fungicides. You have to follow the sanitation procedure to fix the tree from this problem.
Hydrogen Dioxide and Peroxyacetic Acid are very effective in killing fungi. You mix any of these with water to make a dilute solution. The ratio of water and chemicals will be 3:1. Then spray twice a day with a spray bottle on each affected leaf of the plant.
2. Yellow Ring on Leaf
This disease is usually more noticeable in young Blush Pink Nandina trees. Light green or yellow rings are visible on the leaves. But the rings are irregular and do not follow any pattern. This weakens the plant and disrupts its normal growth of the plant. If control measures are not taken quickly, the tree dies.
- Cold Weather
Although Nandina is a cold-loving tree. However, due to excessive cold, the tree may be affected by various viruses. If your plant is indoors, you can easily control the temperature with a temperature controller machine. If it is in the landscape, use a cloth to protect the plant from the cold wind.
Once the virus attacks a plant, it cannot be easily controlled. Chemical sprays are not very effective in most cases. But in such situations, I spray diluted dry milk. Which gives quite good results. It should be applied directly on the affected leaves of the plant once every three days.
If the virus infection gets out of control, the affected part of the plant should be removed and immediately buried or burned. Spraying the plants with fresh water every morning and evening helps prevent the virus.
Chlorosis occurs in Nandina leaves due to a lack of essential nutrients. The colour of the leaves is greenish yellow at first and later turns completely yellow. But the veins remain green. This problem can be easily identified by looking at the changes in the leaves.
- Lack of Iron
- Lack of Nitrogen
Plants get their essential nutrients from the soil. So first of all good quality soil must be ensured. When preparing the soil there should be more organic matter and peat moss.
For early iron chlorosis, you can use ferrous sulphate. The chemical can be applied directly to the soil or mixed with water at the base of the plant. But for severe iron chlorosis, you need to apply iron chelates. It can be applied directly to the soil. I make several small holes at the base of the plant and sprinkle a small amount of iron chelate powder on them.
A good quality nitrogen-rich fertilizer can be used to compensate for nitrogen deficiency. Or you can apply organic compost. Adequate ventilation of the soil should be ensured. Green manure crops and fish emulsions are also very effective for increasing the nitrogen level in the soil.
4. Leaf Scorch
Leaf blight is a very common problem of Nandina plants. Usually, the burn starts from the tip of the leaf and gradually the entire leaf turns brown. The leaves crumble when touched.
Unfortunately, there is no effective solution to the Nandina leaf scorch problem. However, sanitation methods can work to some extent. Some antibacterial sprays can temporarily control the infection. But this disease can easily be kept away by proper care of the tree. Do deep watering once a week and apply mulch to the plants.
A good quality pesticide should be used to protect the plant from pests. An effective insecticide can also be prepared at home by mixing neem oil with baking soda.
How to Take Care of A Blush Pink Nandina Tree?
Nandina can usually be grown both indoors and outdoors. A slightly acidic and well-draining soil should be selected. If planting the plant outdoors, barriers should be provided to avoid unnecessary root growth. A sunny spot with partial shade is ideal.
The Nandina tree needs occasional light pruning of its long stem and branches to give it a nice shape. This pruning can be done at any time of the year.
A small amount of fertilizer is recommended for the normal growth of Nandina plants. Usually fertilizers rich in nitrogen, iron, and magnesium. Good for plant growth. Late February or early June is the ideal time to apply fertilizer.
