1, the temperature is still low. If the temperature is lower than 10 degrees, the leaves will turn yellow. If it is below 5 degrees, there is a danger of frostbite. It is suggested that the room temperature should not be lower than 16 degrees to avoid yellowing of leaves.
2, often do not change the water, resulting in unclean and smelly water, causing root rot, and it is easy to cause yellowing of leaves.
Dry air is also a cause of yellowing of leaves. At noon on a sunny day, spray more water around and on branches and leaves to improve humidity.
3. There are too many nutrient solutions, and many people like to add nutrient solutions to the water. Here, if hydroponic flowers are not seriously deficient in fertilizer, try not to add nutrient solution. If it is added frequently, the concentration is not well mastered and it is easy to cause fertilizer damage.
4, the light is too strong, indoors in a bright place, if the light is strong at noon, it is recommended to shade a little.
Yes, nutrient solution is needed, but Guanyin bamboo is easier to raise. If the upward trend is good, you don't need to add it.
Preliminary cultivation method of Guanyin bamboo;
first
Choose the one with lush foliage and prepare water to dry for a few days. If you bought it temporarily, soak it in tap water for a while, heat it up to remove chlorine, and then put it in. Bamboo will not die if it goes home for a day without drinking water.
then
Before putting it in the bottle, remove the leaves from the bottom of the cutting and cut the bottom from the seam with a sharp knife. Leaves should be smooth to increase the absorption area of water and nutrients. If there is no problem, it is better to change the water quality less. /kloc-Don't move the position and change the direction within 0/0 days. Generally, small white protrusions begin to grow in a little over a week, which is the initial form of roots. Early roots (silvery white fibrous roots) can be seen after two weeks.
In the first two or three weeks, the leaves will turn yellow because they have to adapt to the new environment and take root. Don't worry, just cut off the yellow part of the leaves, only cut off a small area of the yellow part, leaving green leaves. It is normal that the roots are white and thick in the early stage, and will become smaller, yellow and black after a long time. If black roots affect appreciation, it is ok to cut off some small roots appropriately.
Growing environment:
Put it in a well-ventilated and bright place, preferably in a place with high brightness and no direct sunlight for a long time. Guanyin bamboo likes humidity, high temperature, waterlogging resistance, fertilizer resistance and cold resistance. I like a semi-shady environment.
Summer and autumn are hot and rainy, which is very beneficial to the growth of Guanyin bamboo and is the best time for its growth. It does not need strict illumination and is suitable for growing under bright scattered light. Excessive light and exposure can cause leaves to turn yellow, fade green and grow slowly.
There will be radiation when placed near the TV or computer, but the harm is not too great, so it is not necessary to avoid it deliberately.
Water change management:
After changing water, it is not advisable to change water and add water to take root, and water can only be added in time after water evaporates. Changing water frequently can easily lead to yellowing of leaves. Better add well water. Tap water should be stored in a container for one day. Water should be kept clean and fresh. Dirty water, hard water and oil and water should not be used, otherwise the roots will rot easily.
If the water stinks, take out the bamboo, rinse the roots of the bottle and Guanyin bamboo, remove most of the tiny roots, and replace them with fresh water that has been dried for more than 1 day. If the water still stinks, cut off the roots of Fu Guizhu and let them grow again.
Fertilizer management:
Fertilize and water bamboo in time to prevent overgrowth. Do not apply chemical fertilizer. It is best to add a small amount of nutrient solution into the bottle every three weeks or so. You can also go to the flower and bird market to buy fertilizer for liquid green leaves. Don't add too much fertilizer, it will burn to death.
If you are not afraid of Guanyin bamboo growing too luxuriantly, you can use chemical fertilizer. Guanyin bamboo is more tolerant to fertilizer. Generally, compound fertilizer should be used for fertilization every 2-3 months. If it is hydroponics, potassium dihydrogen phosphate should be added after changing water every two weeks to ensure its normal nutrient absorption.
After rooting, a small amount of culture solution or NPK compound fertilizer should be added in time to ensure that the branches are strong, but not too much, otherwise it will cause root burning. Generally speaking, fertilizing once a month is enough.
