What if the latest leaves of Cymbidium turn yellow?

Ink orchid, also known as Orchid, is one of the traditional orchids in China, and it is also a rare variety of Chinese orchids. Now it is one of the more popular national orchids, which can be placed indoors as decoration, or as a gift to friends. Many people will encounter the situation of yellowing leaves in the process of breeding Mulan. How is this going on? Next pro-agriculture network to introduce to you how to do the yellowing of the leaves of the orchid.

What should we do about the yellowing of the leaves of the orchid? first of all, we need to know what causes the leaves of the orchid to turn yellow. Here, the pro-agriculture network summarizes four reasons, and then introduces the corresponding treatment methods according to these reasons. Let's take a look at them.

First, too much watering

In the process of watering the orchid, we should not pour too much water at one time, the water can not be absorbed in the soil, it can easily lead to root rot, leaves will naturally yellow, and if serious, it will lead to the death of the whole plant. Watering methods should also be noted, not directly from the head down, because this may cause water to flow into the buds, but also lead to leaves yellowing.

Solution:

It is mainly a question of timing and measurement of watering, usually in winter and spring, watering is best before and after sunrise, and spray increases air humidity to benefit the growth of magnolia. Watering before and after sunset in summer and autumn can ensure that the leaves are dry before nightfall. When we find that the soil surface is too dry, we should prepare to water it. Don't let the soil dry for too long. When watering, it is better to water along the edge of the basin.

Second, excessive fertilization

When Magnolia is growing, the demand for fertilizer is not very large, so it is necessary to control the number of times and the amount of fertilizer each time. If excessive fertilization will lead to overnutrition in the basin soil, it will cause Magnolia to burn roots and the leaves will turn yellow.

Solution:

Fertilization should be moderate, not too much. Fertilize once a week during the growth period, the growth of Magnolia is slow in autumn and winter, apply fertilizer once every 20 days, do not pour it on the leaves, pour a small amount of water after fertilization, and clean the residual fertilizer in the soil. At the same time, the time of fertilization is mainly in sunny days, and fertilization in cloudy days will lead to the risk of rotting roots.

Third, the temperature is too low

If there is yellowing of leaves in winter, in addition to the above two reasons, but also consider the influence of temperature, too low temperature is also likely to cause leaves yellowing, especially the sub-zero temperature.

Solution:

Don't put Mulan outdoors in winter, pay attention to keeping Mulan warm. The most suitable temperature for the growth of Cymbidium is 18 ℃ ~ 28 ℃. It grows slowly below 10 ℃ in winter and goes into dormancy. However, the winter temperature can not be too high, higher than 25 ℃ will affect the dormancy of Cymbidium, affecting the growth of the following year.

Fourth, lighting

Light is a factor that is difficult to control. Too strong or too weak light may cause the leaves of Cymbidium to turn yellow. Excessive light can easily cause sunburn of leaves. Excessive shading or long-term indoor exposure will affect the photosynthesis of orchids, resulting in yellowing leaves, poor growth and not easy to blossom.

Solution:

Mulan needs a certain amount of light, but it can't stand the strong light. the sun before nine o'clock every morning is of great help to the growth of Mulan. After nine o'clock, it is necessary to move to the shade or shade it, especially in summer and autumn. Sunny days should have more than 70% shade.

These are the reasons and solutions for the yellowing of the leaves of the orchid summarized by the pro-agricultural network, hoping to bring some help to you. Since ancient times, orchids have been a symbol of non-secular, noble and elegant, so raising a pot of orchids at home also symbolizes the master's pursuit and yearning for this character, which is the favorite of many literati.
