Why the leaves of hydroponic chlorophytum are yellow?
1, too bright.
Chlorophytum is a shade-loving flower and cannot accept strong sunlight. If there are flower friends raised in Nanyang terrace, it is very easy to get yellow leaves.
Solution: Chlorophytum can be maintained in indoor places with scattered light, such as living room and bedroom. Don't get too much sun.
There is not enough fertilizer.
Hydroponics can't absorb more trace elements like soil culture. If water is not changed frequently, it is easy to cause malnutrition and yellow leaves.
Solution: Chlorophytum is mainly applied with nitrogen fertilizer, and urea and water can be mixed according to the ratio of 1:800 and applied in bottles. Be careful not to overdo it, or the roots will burn easily.
3. Not trimmed in time.
Too thick leaves will accelerate the absorption of nutrients and turn yellow. In addition, too many miscellaneous roots will affect the absorption of nutrients by chlorophytum, which will also lead to yellowing of leaves.
Solution: Cut off the yellow leaves in time. If the chlorophytum is too dense, it can be beheaded to ensure the normal growth of other leaves, trim off excess virtual roots and make the roots fully absorb nutrients.
Why are the yellow leaves of hydroponic radish yellow leaves?
1, environmental mutation.
Generally, newly bought green radish will have a process of adapting to the new environment when it gets home. It is normal for the leaves to turn yellow at this time. Just cut off the yellow leaves in time.
Solution: You can put the newly bought green radish in the bedroom or other scattered light places at home and wait for it to serve.
2. Insufficient nutrition.
There is not as much nutrition in water as in soil, and insufficient nutrition will also cause radish leaves to turn yellow.
Solution: Green radish is also a foliage plant, mainly applying nitrogen fertilizer. In addition to urea, we can dilute it 20 times with decomposed soybean water and add a little to the hydroponic bottle. Usually, we can spray water on the leaves.
The water quality is very poor.
Some flower friends directly raise green radish with tap water at home without any other treatment. Chlorine in tap water is not good for the growth of green radish, which easily leads to yellow leaves.
Solution: Change water frequently. The water in the hydroponic bottle can be added to about 1/2 of the bottle, and the water can be changed 1 time every two weeks. When changing, you don't need to take the root out, just pour it along the flat edge.
Why does hydroponic copper money grass have yellow leaves?
1, malnutrition. Copper money grass grows fast, so the nutrients in the water are consumed quickly. If the yellow leaves lodging, it is probably insufficient nutrition.
Solution: half soil and half water culture. In this way, it can meet the needs of copper money grass for water and nutrition at the same time, killing two birds with one stone. First add soil to the bottle to 1/2, then plant copperas, add water, and add slowly. Don't pour copperas, wait until the water is low.
2. Poor ventilation. Even in hydroponics, copperhead snakes still need a well-ventilated and not stuffy environment. If the air is too humid and does not circulate, it is easy to cause the leaves of the copperhead snake to turn yellow and wither.
Solution: Pay attention to the placement position. Put hydroponic copperas in a sunny and ventilated place, such as Nanyang Terrace.
Why does hydroponic bamboo have yellow leaves?
1, improper fertilization. Newly bought rich bamboo generally has no roots, and its ability to absorb nutrients is poor, and it is easy to yellow leaves; However, excessive fertilization can also cause the leaves of Fu Guizhu to turn yellow.
Solution: The newly bought Fu Guizhu can be cut with its lower end inclined at 45 degrees to increase the area for absorbing nutrients and promote rooting; If fertilization is excessive, stop fertilization immediately, cut off yellow leaves, change water again and dilute fertilizer.
2. Improper lighting. Due to insufficient light, Fu Guizhu can't carry out full photosynthesis, and the leaves will not be green; Bamboo leaves will turn yellow if the light is too strong.
Solution: Fuguizhu likes the shade and is not strict with the light, so it can be placed in the living room at ordinary times.
3. Don't change the water. Hydroponic green plants can't keep changing water. After a period of use, the oxygen and nutrition in the water will decrease, and gradually they can't meet the requirements of Fugui bamboo.
Solution: the water quality becomes worse, which is easy to breed bacteria and affect Fu Guizhu's breathing. Usually change the water once a month, and usually add water to the bottle when there is little water.
Why are the leaves of hydroponic bamboo yellow?
1, nutritional deficiency. After a long time of hydroponics, the leaves of Phyllostachys praecox are easy to turn yellow due to the lack of nutrition in the water.
Solution: Big bamboo is a relatively large foliage plant. You can always prepare some special nutrient solution at home. Add a drop or two to the water every month and the leaves will be green.
2. The temperature is too low. Bamboo is not cold-resistant, the temperature is too low in winter, and it is easy to yellow when frozen.
Solution: When the temperature is low in winter, we should pay attention to keep bamboo warm, receive more light during the day, and be careful not to be affected by the cold wind, otherwise it will be easy to get frostbite.
3. Poor ventilation. Although Phyllostachys praecox likes humidity, if the air is not circulated for a long time, the environment will be humid and sultry, and its leaves will easily turn yellow.
Solution: put bamboo in a ventilated place at home and spray water around it often to keep the air fresh.
