What if the leaves of Cymbidium are yellow?

The common reasons for the yellowing of the leaves of Cymbidium are improper lighting, improper watering, excessive fertilization and metabolism. Among them, metabolism is a normal growth phenomenon of plants, which is characterized by the natural yellowing and drying up of the old leaves underneath.

Many flower friends prefer the cultivation of Cymbidium, although it is said that Cymbidium does not blossom when it is young, and it generally takes more than two or three years to blossom, it still can not stop people from loving it. Because the green leaves of the four-round embellish season all the year round let people see the scene of vitality, and the flowering orchid is admiring. So what should we do when we encounter its leaves yellowing when we are protecting the magnolia? Today, Hua'er Valley will come and discuss it with you.

1. Improper lighting

When the orchid is illuminated by strong light, the leaves will turn yellow. Especially in summer, we can not let the orchid grow in the sun, otherwise it will cause high temperature and high light harm. On the other hand, if we keep it in a dark place for too long in order to avoid the damage of light, it will also cause lack of light and yellowing.

Solution method

In summer and other high temperature and strong light, we need semi-shade to maintain the magnolia, not only to let it enjoy the light in the process of growth, but also to prevent the burning of the sun. As long as the light is bright and sufficient, Magnolia can make full use of light for photosynthesis and promote its own growth. If a scorching sun or long-term shade causes the leaves to turn yellow, we just need to put them in a well-ventilated, brightly lit place to slowly recover.

2. Improper watering

If you don't water the magnolia for a long time, it will lack water and the leaves will turn yellow and dry. The physiological needs of water-deficient orchids are limited, at least in terms of water, which has suppressed the normal demand for its growth. On the contrary, we irregularly water, excessive watering causes the basin soil to be too wet or stagnant water, it will cause the root breathing is not smooth and the leaves turn yellow.

Solution method

To water the magnolia, we must be regular and skillful. We must master the principle of watering dry and wet. This will not make it lack of water for a long time, nor will it make the soil stagnant or too wet and rotten. If the rotting roots of Cymbidium caused by stagnant water for a long time, we need to take it out of the soil, cut off the rotten roots and disinfect them, and then change the pot to change the soil for planting.

3. Improper fertilization

The first thing to say about improper fertilization is the yellowing of leaves caused by nutrient deficiency caused by long-term non-fertilization, and the second is the yellowing of leaves caused by excessive fertilization. Long-term non-fertilization or excessive use of nitrogen fertilizer will cause yellowing of leaves, excessive fertilization will cause fertilizer damage and root burning, resulting in leaves drying and yellowing due to lack of water and nutrients for growth.

Solution method

After any kind of flower is maintained for a long time, the nutrients of the basin soil will be consumed to a certain extent, and the nutrients will slowly disappear with the running water when watering. We can give the orchid some self-made fully mature fat cake water and organic fertilizer liquid. We can also buy some special fertilizer for orchids. Or we can use some nitrogen, phosphorus and potassium compound fertilizer before flowering, which can make it grow better, blossom more, and avoid yellowing of leaves. If it is excessive fertilization, we need to use a lot of water to wash the basin soil in time, which can dilute the fertilizer liquid in the soil and let it return to normal growth.

4. Metabolism

With the cultivation of Cymbidium for a long time, there will be some older leaves under it, which will slowly turn yellow and wither, which is a normal metabolic phenomenon. At this point, we just need to observe that the new leaves are not abnormal and there is no need to deal with them. Or we can prune the old yellow leaves for him to make the plant grow more beautiful.
