Hydroponic Cymbidium yellow leaves

Flower cultivation Daquan

Why the yellow leaves?

1. The light is too strong.

Hanging orchids are more shady flowers, can not accept the strong light of the sun, if some flower friends keep it on the south balcony, it is very easy to yellow leaves.

Solution:

Hanging orchids can be maintained indoors where there is scattered light, such as living rooms, bedrooms and so on. Don't give too much sunlight.

2. There is not enough fertilizer.

Hydroponic orchids can not absorb more trace elements like soil culture, so if you do not change water often, it is easy to cause insufficient nutrition and lead to yellow leaves.

Solution:

Hanging orchid mainly applies nitrogen fertilizer, can be mixed with urea and water in the bottle according to the proportion of 1RU 800, be careful not to excessive, otherwise it is easy to burn roots.

3. Not pruning in time.

Too dense leaves will accelerate the absorption of nutrients, leaves will turn yellow, in addition, too many miscellaneous roots will affect the absorption of nutrients, but also lead to yellow leaves.

Solution:

Cut off the yellow leaves in time, the hanging orchid is too dense can carry out "beheading" operation, to ensure that other leaves can grow normally, trim off the excess virtual roots, so that the roots can fully absorb nutrients.

Hydroponic green and yellow leaves

Flower cultivation Daquan

Why the yellow leaves?

1. Abrupt change of environment.

Generally speaking, the green pineapple you just bought will have a process of adapting to the new environment, and it is normal to have yellow leaves at this time. Just cut off the yellow leaves in time.

Solution:

You can put the green apple you just bought in the bedroom or other places at home where there is scattered light, and wait for it to take the basin.

2. Lack of nutrition.

The nutrition in the water is not as much as that in the soil, and the lack of nutrition will also lead to the yellowing of green radish leaves.

Solution:

Green pineapple is also an ornamental foliage plant, mainly applying nitrogen fertilizer. In addition to urea, we can dilute it with rotten soybean water 20 times and then add a little bit to the hydroponic bottle. We can spray water on the leaves at ordinary times.

3. The water quality is poor.

Some flower friends raise green pineapple directly with tap water at home, without other treatment, the chlorine in tap water is disadvantageous to the growth of green pineapple and can easily lead to yellow leaves.

Solution:

Change the water frequently. The water in the hydroponic bottle is added to the bottle's 1x2 or so, and the water is changed every 2 weeks. You don't have to take the root out when changing, just pour it along the flat edge.

Hydroponic yellow leaves of Rabdosia angustifolia

Flower cultivation Daquan

Why the yellow leaves?

1. Lack of nutrition. Tongqian grass grows very fast, so the nutrition consumption in the water is also very fast, if there is the phenomenon of lodging of yellow leaves, it is likely to be undernourished.

Solution:

Half-soil, half-water farming. This can meet the water and nutrition needs of Tongqian grass at the same time, killing two birds with one stone. First add soil to the bottle, then plant copper grass, and then add water, add slowly, do not wash down the copper grass, and then add less water.

2. Poor ventilation. Even if it is hydroponic, it still needs a well-ventilated and non-suffocating environment. If the air is too humid and not ventilated, it is easy to cause the leaves to turn yellow and wilt.

Solution:

Pay attention to the position. Put hydroponic copper grass in a sunny and airy place, such as the south balcony.

Hydroponic culture of rich bamboo yellow leaves

Flower cultivation Daquan

Why the yellow leaves?

1. Improper fertilization. The newly bought rich bamboo generally has no roots, so it has poor ability to absorb nutrients and is easy to have yellow leaves; but excessive fertilization will also lead to the yellowing of rich bamboo leaves.

Solution:

The newly bought rich bamboo can tilt the lower end by 45 °to increase the area of absorbing nutrients and promote rooting. If you apply too much fertilizer, you should immediately stop fertilization, cut off the yellow leaves, change water and dilute the fertilizer.

2. Improper illumination. Lack of light, rich bamboo can not carry out sufficient photosynthesis, the leaves will not be green; too strong light, rich bamboo is not sun-resistant, the leaves will turn yellow.

Solution:

Rich bamboo likes yin, and the requirements for lighting are not too strict, so it can be put in the living room at ordinary times.

3. Do not change the water. Hydroponic green plants can not keep changing water, the oxygen and nutrition in the water will be reduced after a period of time, and slowly can not meet the needs of rich bamboo.

Solution:

When the water quality becomes worse, it is easy to breed bacteria and affect the breathing of rich bamboos. Generally, the water is changed once a month. When there is less water, you can add water to the bottle.

Hydroponic turtle back bamboo yellow leaves

Flower cultivation Daquan

Why the yellow leaves?

1. Lack of nutrients. Hydroponic culture for a long time, insufficient nutrition in the water, it is easy to lead to tortoise back bamboo yellow leaves.

Solution:

Tortoise back bamboo is a relatively large foliage plant. You can always have some special nutrient solution at home. If you add one or two drops to the water every month, the leaves will be green.

2. The temperature is too low. Tortoise back bamboo is not cold-resistant, the temperature is too low in winter, tortoise back bamboo is easy to yellow leaves when frozen.

Solution:

When the temperature is low in winter, you should pay attention to keep the turtles warm, receive more light during the day, and be careful not to be exposed to cold wind, otherwise you are prone to frostbite.

3. Poor ventilation. Although the tortoise back bamboo likes to be moist, if the air is not ventilated for a long time, resulting in a wet and stuffy environment, it is easy to make its leaves yellow.

Solution:

Put the tortoise back bamboo in a ventilated place at home and often spray water around to keep the air fresh.
