All the friends who have ever raised rich and noble bamboos know that as long as rich and noble bamboos can take root and their leaves do not turn yellow, they can keep them very well. But the most common problem many people encounter when raising rich and noble bamboos is that their leaves turn yellow. What's the matter? What to do? Let's get to know each other.
What to do with the yellow leaves of the rich and noble bamboo
There are many reasons for the yellow leaves of Phyllostachys pubescens. We should reduce the light of Phyllostachys pubescens, cut the roots and replant them, and pour more water.
1. Reduce light
Reason: when the bamboo is exposed to strong light for a long time, yellow spots will appear on the leaves. The whole leaf looks yellow and has no luster.
Solution: move the rich and noble bamboo to the indoor place with scattered light, and maintain it slowly.
2. Increase light
Reason: the leaves of Phyllostachys pubescens were too shaded for a long time, and there was not enough sunlight for photosynthesis, so they could not synthesize nutrients and then turn yellow.
Solution: move it to a sunny but not strong place for maintenance.
3. Cut roots and replant
Reason: usually too much water or too much fertilizer will affect the root of rich and noble bamboo. Light causes the root to blacken and heavy causes the root to rot. When the root system is damaged, it will directly affect the efficiency of nutrient absorption, leading to the lack of nutrition in the leaves, and start to turn yellow.
Solution: take the bamboo out of the water or soil, observe the roots, and use the sterilized scissors to cut off the black and rotten roots. Then spray some medicine to the wound for sterilization, and then put it in a cool place to dry. Wait until the agent is dry, and then use the new medium for cultivation.
4. Pour more water
Reason: water is the raw material of photosynthesis reaction of Phyllostachys pubescens. Once water shortage occurs, it will not be able to produce photosynthesis synthesis nutrients in the leaves, so it will turn yellow.
Solution: pour more water on the rich and noble bamboo to ensure sufficient water supply.
5. Supplementary fertilizer
Reason: if we do not fertilize the rich and noble bamboo for a long time, it will lead to the lack of nutrients that the plant can absorb, and the leaves will turn yellow without nutrients.
Solution: apply some fertilizer to the rich and noble bamboo, but not too much. Apply thin fertilizer frequently.
What's the matter with the yellow leaves of the rich and noble bamboo
There are several main reasons for the yellowing of Phyllostachys pubescens
1. In general, only when the temperature is 6-8 ℃, can the bamboo survive the winter safely. This can happen if the room temperature is too low, or if the room is moved into a cool shade room after being cold outside.
2. In winter, water is not often added or changed, but also lack of nutrition, and long time in the shade of the indoor, it will also cause such a situation.
3. It is also one of the reasons that the plant is not suitable for purchase, and it has not yet rooted in the early winter.
resolvent:
1. The yellow leaves and stems should be removed immediately, and the space can be replaced by non yellow plants.
2. Place the room with light, keep the minimum room temperature at 6-8 degrees. In case of low temperature, cover the basin with 1-2 layers of plastic bags, and keep away from the glass window at night.
3. Add water to prevent drying, and change the temperature water once in 7-10 days. Fertilization should be stopped during the winter.
