How to deal with the yellowing of Guanyin bamboo leaves

1. Improper lighting

Reason: although Guanyin bamboo is a semi-shade plant, if the plant is over-illuminated, the leaf edge and branches will shrink, the leaf tip and leaf edge will wither, and the sunrise part will appear macula. If there is not enough light for a long time, the plant will not be able to carry out photosynthesis, and the leaves will turn yellow and then fall.

Solution: the plant can be moved to the sun for 3 hours a day, but the summer should be shaded to avoid strong light exposure, and then the plant can be moved to a cool place for care.

two。 Improper watering

Reason: Guanyin bamboo likes a humid environment, but it is necessary to control the amount of water the plant is watered. If too much watering, the new leaves of Guanyin bamboo become yellowish and lack of luster, the branches shrink, and the plants do not grow well. However, if there is a lack of water, the edges of the leaves will dry up, which will also make the leaves yellowing, and then the leaves will begin to fall.

Treatment method: if the plant is overwatered, the plant should be taken out of the pot soil, ventilated and dried, and then moved to a cool place to be replanted. If you are short of water, you should replenish it in time, but you should pay attention to making the soil moist.

3. Excessive fertilization

Reason: excessive fertilization or excessive concentration will also lead to yellow leaves, usually the new leaf tip appears dry brown, the leaf surface is thick and dull, the leaf surface is concave and convex, and the old leaves are scorched yellow.

Solution: stop fertilizing at this time, use an appropriate amount of water to clean the roots, and if serious, change the soil.

4. Rotten root

Reason: if the Guanyin bamboo is cultivated in water, the poor water quality will breed germs, which will cause the roots to rot and the leaves to turn yellow.

Treatment: change clean water in time, use tap water that has been standing still for several days or cold boiled water directly. Cut off the rotten roots and spray some carbendazim to sterilize.

How to solve the yellowing of Guanyin bamboo leaves

When many friends cultivate Guanyin bamboo, especially novice friends, they often encounter the problem of yellowing leaves, so what about the yellowing leaves of Guanyin bamboo? Next, let's take a look at the solution to the yellowing of Guanyin bamboo leaves.

The main results are as follows: 1. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

2. Dry yellow: the yellow with lack of water is different from the yellow with more water, the yellow with lack of water is withered or dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal. Pay attention to watering enough and thoroughly.

3. Burning yellow: strong sunlight shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which can easily cause withered leaf tips and edges, and macula in the sunrise part of the leaves. Just move to the shade.

4. Lack of light and yellow: put in a shady environment for a long time, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

5. Fat yellow: flowers yellowing caused by too much fertilization or too much concentration, showing dry brown at the tip of new leaves, general leaf thickening and no luster, and concave and convex not stretching, old leaves scorched yellow shedding. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

6. lack of fat yellow: the color of the tender leaves becomes lighter, yellow or light green, while the old leaves are more normal or gradually change from green to yellow. Check the basin soil, if there is a dry phenomenon should change the soil, usually apply thin fertilizer frequently and timely sprinkle some alum (Guanyin bamboo is Guanyin bamboo should be nitrogen-based fertilizer).

7. Root-cutting yellow: don't cut off the roots in winter, so they can't absorb water, and the leaves will naturally turn yellow.

Some common sense that should be paid attention to in culturing Guanyin bamboo:

1. Use water: when we use water for aquaculture of Guanyin bamboo, we should add 2/3 of the water when changing the water, keep 1/3 of the water, and don't pour out all the water.

2. Depth of water discharge: the water should not be put too deep, only 1/2 or 5/3 of the water is needed. It is suggested that we use transparent vases for the culture of Guanyin bamboo, so that we can know the height of the water and observe the growth of roots.

3. Peeling leaves: before we enter the bottle, we should peel the leaves to the mouth of the bottle, and at the same time, peel off the leaves attached to the stem until we see a circle of bamboo knots exposed, not to say that the leaves will be removed or cut off. When we see the yellowish skin can be said to be peeled clean, so that we can avoid changing the water in the future, the water will not stink easily, and the stem will not have that kind of slippery feeling, after the leaves are peeled clean, the base can be cut into a slant with a knife to facilitate the absorption of water and nutrients.

What if the leaves of Phyllostachys pubescens turn yellow?

Phoenix tail bamboo water yellow

It is shown in that the young leaves of Phyllostachys pubescens are dull, the changes of the old leaves are not obvious, the branches are gradually small, and the new shoots are wilting.

Solution.

Put the flowers in a dry and ventilated position for maintenance, wait for the air to dry and then put them back into the basin soil.

Phyllostachys pubescens dry yellow

Too little watering of Phyllostachys pubescens will also lead to the phenomenon of yellowing of leaves, too little watering, dry edges of leaves, old leaves gradually yellowing and falling off from top to bottom, but the growth of new leaves is still relatively normal.

Solution.

Pay attention to watering more and pour it thoroughly.

The Phoenix tail bamboo is burning yellow.

The phenomenon of yellowing of leaves will be caused by strong sunlight, which is characterized by leaf tip, leaf edge drying up, and leaf parts showing color change spots.

Solution.

Just put the burned bamboos in a cool and dry place.

Phoenix tail bamboo fat yellow

Too much fertilization to plants will also cause the phenomenon of flowers yellowing, mainly manifested in the brown on the top of the plant leaves, generally thick leaves without luster, and uneven, old leaves withered and yellow.

Solution.

Stop applying fertilizer to Phyllostachys pubescens. If the disease is serious, it can be irrigated with clear water and drained to gradually reduce the concentration of fertilizer.
