The hydroponic culture of orchid green turnip is always taught by yellow leaves to teach you three tricks to become green immediately.

[0076], hanging orchid green turnip hydroponics is always yellow leaves, teach you 3 tricks, immediately become green!

Hydroponic flowers are very clean, and the management is simple, so there is no need to worry about watering, but hydroponics often cause leaves to turn yellow because of insufficient nutrition. Today, the blue demon will come to tell you how hydroponics can keep plants healthy.

Green turnips grow yellow leaves in water

Green pineapple likes water very much and can be fed by cutting branches and inserting it in water, but green pineapple that has been cultured in water for a long time is often prone to the problem of yellow leaves.

1. Undernourished yellow leaves

When many flower friends cultivate green pineapple in water, they simply add some water, never use nutrient solution or top dressing, so that the growth of green pineapple does not have enough nutrients, and it is easy to yellowing over a long time.

Solution:

When changing water for green pineapple, add a little hydroponic nutrient solution, which can improve the growth of green pineapple, so that it can grow exuberantly and keep green.

If you do not use nutrient solution, you can also use nitrogen, phosphorus and potassium compound fertilizer with more than 2000 times the concentration of water, foliar spraying topdressing. In the vigorous growth season, it should be applied once every 10 days or so.

2. Water quality corruption

Some of our flower friends, hydroponic green pineapple never change water, are you the same? Blue demon hydroponic green apple does not like to change water, but blue demon does not add fertilizer in the water.

If there is no fertilizer in the water, the general water quality is not easy to corrupt, but if you add nutrient solution, it is recommended to change the water regularly, otherwise there are too many microbes in the water, and the water quality will easily cause green radish leaves to turn yellow, even rotten roots, and give off a bad smell.

Solution:

Change the water in time when it is found that the water quality becomes turbid. Tap water should be left at rest for a day before use.

If the rotten root stinks, the rotten part should be cut off, and the green pineapple and hydroponic utensils should be soaked in potassium permanganate water and sterilized.

3. The temperature is too low

In the past few days, the blue demon found that the hydroponic green pineapple did not have the spirit before, because the temperature dropped a lot these days, and it obviously felt cold.

Low temperature is also a big reason for green radish and yellow leaves, green pineapple is not resistant to cold, especially the cold tolerance of hydroponic culture is even worse.

Solution:

Hydroponic green pineapple should be kept in a warm place in winter, or hydroponic bottles should be placed in routers, fish tanks and other places where the water temperature can be raised.

Hydroponic yellow leaves of Cymbidium

The hydroponic culture of Cymbidium is easy to survive, but it is also prone to yellow leaves. The yellow leaves of hydroponic orchids are mostly due to the following reasons.

1. The light is too dark

Cymbidium is a kind of plant that likes light and is not sun-resistant and shade-tolerant. Therefore, when hydroponics, you can't put it in a place where there is no light at all, or even in a place that is too dark. Too dark crossing the line will cause the leaves of Cymbidium to become bright yellow, and the leaves are brittle and easy to break.

Solution:

Put the orchid in a bright place, it is best to be exposed to the morning and evening light, there is an appropriate direct light can make the orchid grow more robust and green.

2. Fertilizer is not enough.

Cymbidium grows rapidly, hydroponics must add nutrient solution, not topdressing is easy to cause Cymbidium should not have enough fertility and yellow leaves.

Solution:

Add special nutrient solution for hydroponics in water or spray nitrogen, phosphorus and potassium compound fertilizer solution on leaves.

3. Add too much water

When many flower friends are in hydroponic culture, no matter three, seven or twenty-one, they fill up the water directly, so that the orchid is basically soaked in the water, which can easily cause the root system of the orchid to be unable to breathe and produce rotten roots and yellow leaves.

Solution:

When hydroponic culture, the water should not be too full, as long as the water is not over the root of 1 hand 2 on it. Do not soak the leaves of the orchid in water.

Rich bamboo hydroponic yellow leaves

The rich bamboo bought on the market is generally rootless, we buy back to grow their own roots, but in the process of hydroponic culture is also easy to appear yellow leaves for several reasons.

1. Early fertilization

The newly bought rich bamboo has no roots, and the absorption of fertilizer is poor at this time, so it is not suitable to apply fertilizer at the initial stage of breeding, otherwise it is easy to cause fat injury and wound infection.

Solution:

No fertilizer is applied before hydroponic culture, and the lower end of the newly bought rich bamboo is re-cut to a 45-degree section with a sharp knife, which can increase the water absorption of rich bamboo and promote rooting.

2. Do not change the water

Many flower lovers do not like to change water when they cultivate rich bamboos in water. In fact, it is not a big problem not to change water after growing roots, but in the initial stage of water culture, it is necessary to change water regularly. If you do not change water, it is easy to cause wound infection and rot without rooting if there are more microbes in the water.

Solution:

At the beginning of hydroponics, change the clear water every 3 days and clean the hydroponics utensils.

3. Unreasonable lighting

If you want rich bamboo to grow well, you also need a certain amount of light. If the light is too dark or too strong, it will cause the leaves of rich bamboo to turn yellow.

Solution:

Put the rich bamboo in the bright scattered light, away from the electrical appliances.

4. The temperature is too low

Fugui bamboo is also very afraid of the cold, if the temperature is too low, it will also cause the leaves of Fugui bamboo yellowing and wilting.

Solution.

If you want to find a way to keep warm in winter, you can also turn the rich bamboo cultured in water into soil culture before the beginning of winter, which is more conducive to overwintering.
