Phyllostachys pubescens is a kind of foliage plant, the color of leaves is various, there are four varieties of golden heart, silver heart, Phnom Penh and silver edge. Many people like to cultivate these ornamental plants, so what about the yellow leaves of rich and noble bamboos?
Yellow leaves of newly bought bamboos: lack of nutrition
Most of the newly purchased bamboos have no roots. At the early stage of hydroponics, the absorption capacity of the roots is poor, and the leaves turn yellow due to lack of nutrition. At this time, the nutritional solution is also made in vain.
Solution: wait patiently for a month, and take root gradually. As long as the stem is still hard, you can cut off the yellow leaves, change water for a long time, and new leaves will grow soon.
Yellow leaves of Phyllostachys pubescens in hydroponics: water quality problems
Water is the basis for the growth of Phyllostachys pubescens, which naturally causes the leaves of Phyllostachys pubescens to turn yellow. The water quality is unclear, which causes the root system to rot and blacken, thus causing yellow leaves.
Solution: check whether the root system is fresh. If it is rotten, cut off the rotten part and use cold boiled water instead. During this period, the water should be changed frequently to ensure the water quality is clean, waiting for its slow recovery.
Yellow leaves of Phyllostachys pubescens in hydroponics: too dark or too strong light
When the light is too dark, the rich and noble bamboo can't get enough sunlight, can't form chlorophyll, and will naturally cause the leaves to turn yellow.
If the light is too strong, the bamboo is not suitable for strong light, which will cause the leaves to turn yellow.
In view of these two situations, first cut off the yellow leaves, and then put the plant in a place with suitable light, and properly shade or supplement light, so that it can recover slowly.
Yellow leaves of Phyllostachys pubescens in hydroponics: improper fertilization
Excessive fertilization can also easily cause the bamboo to turn yellow, which is mainly manifested in the dry brown at the top of the new leaf, the thick and lusterless leaf surface generally, and the concave and convex are not stretched out, and the old leaf is burnt yellow and off. At this time, it is necessary to change the water, cut off the yellow leaves, stop fertilization, and make it recover slowly.
The lack of fertilizer is mainly reflected in the fact that the color of the young leaves becomes light, yellow or light green, rather than green; the old leaves generally don't see any big changes, so it's only necessary to add a proper amount of fertilizer.
Yellow leaves of Phyllostachys pubescens in hydroponics: improper placement
Although the bamboo has the function of absorbing radiation and purifying air, it should not be placed too close to the TV and refrigerator, which is easy to cause yellow leaves.
If you find the yellow leaves of rich and noble bamboo, just change their positions and keep them away.
