Begonia, as a traditional ornamental plant in China, is loved by many horticulture enthusiasts for its beautiful flowers and elegant posture. Recently, many flower friends have reflected that the new leaves of their begonias suddenly appear withered. This not only affects the overall beauty of the begonia but also makes the maintainers feel confused. This article will provide a detailed analysis of the reasons and prevention measures for the withering of new begonia leaves, hoping to help you maintain your begonias.
Reasons for the withering of new begonia leaves1. Insufficient water
Water is the basic requirement for plant growth. If begonias are short of water for a long time, the new leaves will appear withered, especially in the hot summer, when water evaporates quickly and easily leads to withered begonia leaves.
2. Insufficient light
Begonias like sunlight. If they are kept in a dark environment for a long time, the photosynthesis of the leaves will be weakened, leading to the withering of new leaves.
3. Soil problems
Soil that is too heavy or has poor drainage can easily lead to root hypoxia, which in turn affects the normal growth of begonias and causes the new leaves to wither.
4. Pest and disease invasion
Begonias are susceptible to pest and disease attacks, such as aphids and red spiders. These pests absorb the nutrients from the begonia leaves, causing the leaves to wither.
5. Insufficient nutrients
During the growth of begonias, if there is a lack of necessary nutrients, such as nitrogen, phosphorus, and potassium, it can also lead to the withering of new leaves.
Prevention and control measures for begonia withered new leaves1. Watering appropriately
According to the growth habits of begonias, water them in a timely manner to keep the soil moist. During the hot summer, the frequency of watering should be increased to prevent leaf withering.
2. Increasing light appropriately
Place the begonia in a place with plenty of sunlight to allow it to receive adequate light. If there is insufficient light, the plant position can be adjusted accordingly.
3. Improving the soil
Choose well-drained, breathable soil, regularly loosen the soil to keep it loose, and if the soil is too heavy, add sand, perlite, etc., to improve the soil structure.
4. Preventing and controlling pests and diseases
Regularly inspect the begonia plants and take measures in a timely manner when pests and diseases are found. Pesticides can be used for prevention and control, while also paying attention to protecting beneficial organisms.
5. Fertilizing appropriately
According to the growth needs of begonias, fertilize reasonably. During the peak growing period, nitrogen fertilizer can be applied appropriately to promote leaf growth; during the flowering period, phosphorus and potassium fertilizers can be applied to improve flower quality.
There are various reasons for the withering of new begonia leaves, but as long as corresponding preventive and control measures are taken based on the causes, this phenomenon can be effectively improved. This article hopes to provide you with useful references for begonia maintenance. Paying attention to industry dynamics and understanding the latest research results on begonia maintenance is also an important way to improve maintenance levels.
