Why do the leaves of the bamboo I raised turn yellow in the summer, and is there any remedy?

Don't expose to the sun, don't water too often, cut off the yellow leaves, and soon the green leaves will come out.

Hello, bamboo maintenance needs to pay attention to good, do not be yellowed, in addition to control the moisture, fertilization, do a good job of maintenance management, you can be a good maintenance is not easy to yellow.

1. Yellowing

The simplest reason for the yellowing of bamboo leaves is to tan yellow, some flower friends look at the sun very well in winter, so they move the bamboo to the sun to dry, and the leaf color of the bright side will become yellow-green, or simply wither yellow and fall off.

Wenzhu is afraid of strong light, whether it is summer or winter, to avoid direct sunlight, my suggestion is that it is best not to dry directly, put it close to the sun, the leaves will be extraordinarily green. In winter, you can put the bamboo in a scattered place to dry, or bask in the low light in the morning and afternoon to avoid the noon sun.

2. Dry yellow

The second reason for the yellowing of the leaves of Wenzhu is the dry yellow, some flower friends are worried about watering more rotten roots, so they simply do not water for a long time, and the leaves below begin to turn yellow.

The water-deficient yellow leaves of Wenzhu will start from the bottom of the old leaves, first the leaves turn yellow, the petioles are fine, only when the drought is severe, the petioles of the old leaves will be yellow.

When you find that the bamboo is short of water, you will replenish water in time, and the leaves that have not yellowed will return to normal. The leaves that have been dry and yellow are cut off, and new leaves will come out to fill the gaps.

3. Fat yellow

The third reason for the yellowing of the leaves of bamboos is fat yellow, whether it is low temperature fertilization or too high fertilizer concentration and too frequent fertilization, it will cause fat yellow.

If it is liquid fertilizer, not a lot, you can water a lot of water, and then ventilate, if it is solid fertilizer or more fertilizer, it is best to replant with healthy soil after repotting and washing the roots. It is usually recommended to use water-soluble fertilizer for sea meals.

4. Rotten roots

One of the most common reasons for the yellowing of bamboo leaves is caused by excessive watering and rotten roots, and the reason why this reason is put to the end is because it is a bit troublesome to save.

It is best to replant the rotten roots of Wenzhu after depotting and repairing the roots, otherwise the rotten and worse it will be, and it will not be saved.

Pay attention to the reasons for the yellowing of the leaves of bamboo, and then prevent it, it is not easy to yellow the leaves.

1. The leaves are yellowing due to too strong light.

Bamboo prefers semi-shade, avoid strong light growth environment, summer sun is spicy, if the bamboo is exposed to direct sunlight, it will cause the leaves to wither yellow, so in the summer, to put the bamboo in a cool place, from time to time to spray water on the branches and leaves, increase the humidity in the air.

2. Yellowing of leaves caused by improper watering.

Although bamboos like a moist growing environment, they don't like waterlogging, so it is necessary to ensure that the potted soil is dry and wet at all times, and stop watering as long as the surface is moist when watering. You should know that water accumulation in potted plants will easily lead to root rot, and lack of water will easily lead to dry tips, so in the dry season, it is necessary to spray more water on the foliar surface of bamboo.

3. Yellowing of leaves caused by improper fertilization.

When fertilizing, if the fertilizer concentration is too concentrated or the fertilizer that is not completely decomposed is applied, it will cause root burning, which will cause the leaves of bamboos to dry up and fall off, but if the potted soil is barren due to lack of fertilizer, the leaves will also cause yellowing due to lack of nutrients. Bika water-soluble fertilizer can be applied retroactively.

Fourth, the leaves are yellowed due to poor winter management.

Bamboos prefer a warm growing environment, so in winter, you can place bonsai in a sunny place. If the bamboo is placed in a place with no light, ventilation and cold for a long time in winter, it can cause the leaves to wither yellow, so it is required that the indoor temperature in winter should not be lower than 12 degrees, and it should be placed near the window to the south, and the watering should be controlled.

5. Yellowing of leaves caused by poisoning.

If the bamboo encounters toxic gases, compared to smoke and dust, the branches and leaves are also easy to yellow, and when the bamboo plants are too large and the pots are small, or when they encounter pests such as scale insects, it will also cause the branches and leaves to turn yellow, so it is necessary to replace the pot in time and do a good job in pest control measures.

6. Yellowing of leaves caused by infection with pests and diseases.

If the bamboo is infected by scale insects and other insect pests, it will also cause yellowing of branches and leaves, so when infected with insect pests, it should be timely**.

If the bamboo growth is not very vigorous, you can fertilize, you can use the sugar water as fertilizer for watering, so that you can increase the nutrients needed by the bamboo, every half a month with 5% to 10% of the white sugar water to water the bamboo, you can make the bamboo grow luxuriant.

Flower friends who breed Wenzhu generally know that it is a plant with charm, as long as a little maintenance can survive, it has a beautiful form, clear layers, small branches and thin leaves, and it looks particularly quiet and elegant when placed on the balcony or indoors. But sometimes if we don't breed it in a way that makes it easy to make it yellow, which is something we don't want to see, so how do we avoid it?

Bamboo tends to be semi-shady environment, the temperature is usually about 20 degrees is more suitable for the growth of bamboo, the temperature is required to be above 5 degrees in winter, and it is necessary to move indoors as much as possible in autumn and winter. Do not leave it in direct sunlight for a long time, but when the light is not enough in winter, you can increase some light.

The air should not be too dry, and low humidity can also make the leaves yellow, so it is necessary to spray some water on the bamboo from time to time to maintain the proper humidity around the bamboo.

Improper watering, although the bamboo likes a dark and humid environment, but afraid of long-term waterlogging, because the water is easy to make the roots of the bamboo rot, and then a large area of branches and leaves wither and yellow, watering try to touch the soil first, find a little dry and then water. Of course, insufficient watering will also make the leaves yellow.

Sometimes the leaves turn yellow may be a problem with fertilization, because too much fertilization will cause the phenomenon of burning roots, generally less fertilization in winter, about half a month to apply a little trium water-soluble fertilizer, so that the bamboo can better obtain nutrition.

Pests and diseases, red spiders, scale insects are common pests and diseases encountered in bamboo, as long as they occur, it is easy to quickly make the branches and leaves of bamboo yellow, at this time, the roots of bamboo are immersed in water for half an hour, the branches and leaves with insects are cleaned up, and then 5 grams of washing powder mixed with an appropriate amount of water to make a solution to spray the leaves.

The surrounding radiation, bamboos have a certain sensitivity to the environment, so try not to put them next to air conditioners, refrigerators, computers, etc., otherwise the leaves are easy to turn yellow.

Find that there are yellowing leaves to cut off, let it re-hair, after pruning, it is necessary to properly control the water, the potting soil is a little drier, and then watering after the leaves are soft and the branches droop, watering too often, the stuffy roots will cause yellow leaves and yellow stems. Flower pots can grow more vigorously by placing them on a windowsill with a little light and occasionally applying a thin layer of nitrogen fertilizer.

The yellowing of bamboo leaves is generally caused by too much watering or too much light. If it is because of excessive watering, you need to do it correctly. If it's because the light is too strong, move the pot to a cool place.

1.Scientific watering: If you want the leaves of Wenzhu not to turn yellow, you need to water 1-2 times a week.

2.Prune branches and leaves: Cut off all the dead yellow branches, diseased branches and overly dense branches of the plant to improve ventilation.

3.Thin fertilizer and frequent application: compound fertilizer or cake fertilizer needs to be applied during the growth period of bamboo.

4.Pest control: Spray bactericides once a month to eliminate germs.

First of all, we should choose high-quality soil, choose high-quality varieties, spray some pesticides regularly, remove insect pests in time, do a good job of water and fertilizer, do a good job of drainage and ventilation, and maintain the permeability of the soil.

<>1. Replace the soil.

The yellowing of the leaves of the bamboos is most likely a soil problem. If the soil has not been changed for too long, the soil has been seriously compacted, which hinders the respiration of the root system, so that the normal delivery of water and nutrients causes yellow leaves. Change it to soft, breathable, fertile soil as soon as possible.

Be careful to prune the root system properly.

2. Reduce light.

Wenzhu has the ability to tolerate yin and is afraid of direct light. If you leave it in a place with direct sunlight for a long time, it is easy to get sunburned, resulting in the phenomenon of yellow leaves. It should be shaded as soon as possible, or moved to a semi-shaded and well-ventilated place, and it can also be sprayed with water frequently, which can help it recover.

3. Replenish water in time.

If you forget to water during the growth stage, the root system will not be able to absorb the required water, and it will be easy to appear dry and yellow after a long time. In this case, it is necessary to replenish water as soon as possible, you can water it once, let the root system at the bottom also absorb water, and strengthen ventilation, and it will slowly recover.

4. Appropriate amount of top dressing.

Bamboos are very fond of fertilizers, and they must also be topdressed during the growth period. If you don't apply fertilizer for a long time, the soil will be barren, unable to absorb nutrients, and easy to yellow. To apply fertilizer as soon as possible, it is best to apply diluted organic fertilizer for rejuvenation, which can be absorbed quickly and recover quickly.

Before, my bamboo was also yellow, some of the torso was yellow, probably because the indoor temperature was too high, and too dry, I didn't grasp the watering time, you can put the bamboo indoors during the day and outdoors at night, let it absorb some dew, I do this every day, and then I have a lot of new teeth, and the soil is also wet, so I don't need to water at all.

There are many problems with yellowing leaves, but I think there are three problems in home planting in general, the most important of which is the soil, which is too dry and too wet. Sometimes you are busy and forget to water, or take too much care, and it is easy to have problems if you water twice a day. Note that if the soil is slightly damp, don't water it, wait until it's a little whitish before watering, but water it thoroughly when you can get it.

Fertilizer water should not be too thick, it is better to be lighter, 1 1000 is best, and pour it in water. The permeability of the soil should be good, that is, the water will seep down immediately after pouring, and it will not always stop on the surface. Also, the pH value of the soil should not be too high, and slightly acidic is the best.

In addition, there is the problem of air humidity, the general family is relatively dry, the humidity is obviously not enough for Wenzhu, you can spray some water mist, and pour some dew outside at night, so it is much better, the flowers just taken from the flower garden are very vibrant, that is because the nursery is in direct contact with the soil floor, and the humidity is much more than the cement floor at home. Finally, there's a small problem, which is lighting. The light should not be too strong, but the low light is a must, and it is good to put it on the windowsill to receive some morning or evening sunlight every day.

But the summer sun is absolutely unacceptable. Of course, you can't leave it in the house for a long time and take it outside to contact the sun, there must be a process to gradually increase the intensity of the sun, otherwise it is easy to get hurt.

Any newly planted plant will have a "haggard period", which will turn green when the root system returns to normal, and during this period it will maintain temperature and humidity and avoid direct sunlight.
