The leaves of the orchid are evergreen all the year round, and the plant shape of the whole plant is very beautiful, especially when it blossoms, it is like a beautiful bird, which makes people feel refreshing, so it is also called the bird of paradise. Some friends found that the orchid has the phenomenon of rolling leaves when breeding. How is this all the same? Let's get to know it.

1. Excessive fertilization

Many friends who have just come into contact with the orchid cause excessive use of fertilizer due to poor control of the amount of fertilizer, which leads to a series of poor growth phenomena caused by plant root burning. Excessive fertilization often causes leaves to grow wilting, yellowing, withering and curling. Therefore, we must control the amount of fertilizer when fertilizing. if we do not grasp the amount of fertilizer, we can also apply a small amount of fertilizer in the field during watering. In addition, in the preparation of fertilizer solution, it must be fully mature before fertilization, if it is not used after fermentation, it will lead to root burning and bacterial infection.

2. Excessive illumination

Magnolia likes to grow in a warm and humid environment with plenty of light, but if we expose it to strong light in summer, it will lead to poor growth, with light leaves wilting and curling, and heavy ones withering and dying. At this time, because the soil and water of potted plants are limited, they are exposed to strong light for a long time, which can easily lead to excessive evaporation of water in leaves and water shortage. At this time, leaves are most prone to burn and curl. Therefore, in summer maintenance, we must choose semi-overcast environment maintenance, only need to ensure that there are four hours of light every day.

3. Improper watering

In fact, watering only causes water shortage or drought. In the case of high temperature in summer, potted plants are evaporated and dried by light and water, and immediate local watering will also cause plant damage. Because at this time, plants and soil are in a state of high temperature, after watering, the soil cools sharply, so the excessive temperature difference can easily cause root damage and leaf curl. Therefore, watering should maintain the principle of seeing dry and wet, and should not be watered immediately at high temperature, but should wait until normal temperature before watering.

4. Diseases and insect pests

The diseases and insect pests that cause the leaf curl of Hewang orchid are mainly Tetranychus cinnabarinus. The leaves show small yellow-white spots at the beginning, and then the leaves will be curled gradually. Therefore, it is necessary to prevent and control diseases and insect pests as soon as possible, and can be sprayed with propargite or triclofenac EC.
