In spring, everything recovers, and begonia flowers also gradually bloom beautiful flowers. In this wonderful season, some new begonia leaves appear wrinkled, which puzzles many gardening enthusiasts. This article will analyze the reasons for the wrinkling of new begonia leaves and provide corresponding prevention methods.
Reasons for the wrinkling of new begonia leaves1. Insufficient water
One of the most common reasons for the wrinkling of new begonia leaves is insufficient water. As the temperature rises in spring and the evaporation is high, if watering is not timely, the new begonia leaves will wrinkle due to lack of water.
2. invasion of diseases and insect pests
Diseases and insect pests are also one of the reasons for the wrinkling of new begonia leaves, such as powdery mildew, aphids, red spiders, etc., which will invade begonia leaves and cause leaf wrinkling.
3. Insufficient light
New begonia leaves need sufficient sunlight during the growth process. If there is insufficient light, the leaves will wrinkle due to insufficient photosynthesis.
4. Soil problems
Soil problems are also one of the reasons for the wrinkling of new begonia leaves, such as soil compaction, salinization, etc., which will affect the absorption of water and nutrients by begonia roots and cause leaf wrinkling.
Prevention methods for the wrinkling of new begonia leaves1. Timely watering
In spring, with the rise of temperature, new begonia leaves require more water. It is necessary to water them in time and keep the soil moist. The best watering time is in the morning and evening to avoid watering at high temperatures at noon.
2. Control of diseases and insect pests
Regularly check the begonia plants. Once diseases and insect pests are found, take measures in time. For example, for powdery mildew, spray 800 times of 70% methyl thiophanate wettable powder; for aphids, spray 2000 times of 10% pymetrozine wettable powder; for red spiders, spray 1000 times of 20% trichlorfon emulsion.
3. Appropriate increase of light
Place the begonia plant in a place with sufficient sunlight to ensure its normal growth. If conditions permit, appropriately increase the light time.
4. Improve soil
For soil problems, the following methods can be used to improve:
(1) Deeply turn the soil to increase soil breathability;
(2) Apply organic fertilizer to improve soil fertility;
(3) Regularly disinfect the soil to prevent the breeding of diseases and insect pests.
There are many reasons for the wrinkling of new begonia leaves, including insufficient water, invasion of diseases and insect pests, insufficient light, and soil problems. In response to these reasons, we can take corresponding preventive measures, such as timely watering, controlling diseases and insect pests, increasing light, and improving soil. Through these methods, we can effectively prevent and solve the problem of begonia leaves wrinkling and ensure the healthy growth of begonia plants.
