What Happens When the Leaves of a Fortune Tree Turn White
About the phenomenon of the fortune tree leaves turning white and a detailed analysis of the reasons behind the whitening of fortune tree leaves in the field of green plants and flowers, let's understand together.
The fortune tree is also known as "Smooth Guava Chestnut" and is native to Brazil. It is widely cultivated in South and Southwest China. The leaves of the fortune tree may turn white due to a powdery mildew infection, where the leaves develop white spots, which later form a white mold layer. It is necessary to spray carbendazim for disinfection, and during the maintenance process, attention should be paid to enhancing the plant's resistance. Next, I will specifically talk about the causes and solutions for the whitening of fortune tree leaves.
1. Disease Infection
The whitening of fortune tree leaves may be due to a powdery mildew infection, which is a fungal disease. In the early stages of the disease, white spots appear on the leaves, which later form a white mold layer. It is important to remove the diseased leaves and spray fungicides for disinfection. Drugs such as carbendazim and thiophanate-methyl can be used for control.
2. Pest Infection
The whitening of fortune tree leaves may also be caused by scale insect infestation. Scale insects can dehydrate the leaves and branches of the plant, leading to white and dry leaves. It is necessary to remove the infected leaves and dispose of them集中. Insecticides, such as fenvalerate and dimethoate, should be sprayed on the leaves for control.
3. Excessive Sunlight
The fortune tree prefers scattered light. Excessive or insufficient sunlight can lead to the problem of whitening leaves. In summer, it is important to avoid direct sunlight and move the plant to a shaded and well-ventilated area for cultivation. If the plant lacks sunlight, it can be placed in the sun to increase effective sunlight exposure.
4. Improper Watering
Watering only partway can also cause leaves to turn white. It is important to control the amount of water when watering. Avoid overwatering and prevent water accumulation in the pot. Water once a week in spring, once a day in summer, and once every 20 days in winter.
5. Lack of Manganese Element
The manganese element ensures the normal growth of the plant. If the fortune tree lacks manganese during its growth, it can lead to the whitening of the leaves. First, determine whether the plant is deficient in manganese or has excessive manganese, and then make further adjustments.
The comprehensive explanation of what happens when the leaves of a fortune tree turn white and the detailed analysis of the causes of the whitening of fortune tree leaves provided above, hope it helps you.
