How to remedy yellowing leaves of ornamental bamboo
This article provides an overview of how to remedy yellowing leaves of ornamental bamboo and discusses the reasons for yellowing and the solutions for various plant problems. The details are as follows:
Hydroponic Fulu bamboo is prone to yellowing leaves in winter and spring, why? Fulu bamboo is particularly susceptible to yellowing leaves. While it can be easy to care for, it can also be challenging. What are the main reasons for its yellowing leaves?
1. Low temperature causes yellowing leaves
Fulu bamboo is a tropical plant that is sensitive to cold wind and low temperatures. Leaves will turn yellow when the weather gets cold or the temperature fluctuates. Therefore, in winter and spring, Fulu bamboo should be placed near the window and protected from the wind. Keep the windows closed at night and open them during the day when the sun is shining. If there is frost or a drop in temperature, cover it with a bag.
2. Moving the plant around causes yellowing leaves
The root system of Fulu bamboo is very unstable. Once a care position is chosen, try not to move it again. Every move is like moving to a new environment, and the root system needs to adapt again, causing some damage and resulting in yellowing leaves.
3. Frequent water changes cause yellowing leaves
Hydroponic plants do not need to be watered frequently except for high temperatures in summer. Changing water is like changing soil, and the root system needs to adapt again. If it doesn't adapt well, the leaves will turn yellow. I once took care of several Fulu bamboo plants, and there were only 2cm of water in the bottle, which I didn't change all winter. The leaves were still green and healthy; later, I felt it was too dirty and changed all the water to clean water, and the leaves turned yellow the next day.
In such low-temperature conditions, although we cannot change the water, we can add water when it gets low. The water should be exposed to the sun before use.

4. Iron deficiency causes yellowing leaves
Plants need many trace elements during growth, and iron is one of the important trace elements. Fulu bamboo, money tree, gardenia, hydrangea, and azalea plants, in particular, cannot lack iron. Iron deficiency can cause leaves to turn yellow. How can Fulu bamboo "supplement iron"?
We can add a rusty iron nail to the water or a little iron sulfate powder to improve the yellowing of leaves and make the leaves green and healthy.
5. Hard water causes yellowing leaves
Fulu bamboo prefers a slightly acidic environment. If the tap water is too alkaline or the water quality is too hard, it should not be used directly for hydroponic plants, as the leaves will turn yellow over time. The tap water should be exposed to the sun for 2 days before use, or rainwater, river water, or fish tank water can be used, provided that there are no pesticides or disinfectants in the water.
6. New Fulu bamboo turns yellow
Newly purchased Fulu bamboo is prone to yellowing because it doesn't have roots yet. The plant consumes leaves to conserve nutrients in order to adapt to the new environment as quickly as possible. Additionally, changes in light, water, temperature, and humidity in the new environment can cause yellowing leaves.
The solution for yellowing leaves in newly purchased Fulu bamboo is simple: first, remove all yellow and dry leaves, leave a few leaves at the bottom, cut the bottom at an angle, and soak the branches in clean water. Move it to a shady and well-ventilated area, and it will root after 2 weeks.
