Begonias have always been very popular and many families enjoy growing them. They not only bring a pleasing aesthetic experience but also enhance the beauty of the home environment. However, during cultivation, it is often found that the leaves of begonias turn yellow. So, what to do when the leaves of begonia turn yellow? First, you need to find out the cause of the yellowing leaves, and then I will discuss the solutions for the yellowing leaves of begonias.
【Solutions for begonia leaves turning yellow】
<1, Soil unsuitability causes leaves to turn yellow>
For growing begonias, when the soil is alkaline, it can lead to the yellowing of begonia leaves. Therefore, unsuitable soil can cause begonia leaves to turn yellow.
Solution: When growing begonias, choose suitable acidic soil, such as garden soil, leaf mold, and river sand. Or use a mixture of leaf mold, peat soil, and coarse sand, and add a little base fertilizer.
<2, Insufficient lighting>
Begonias prefer a sunny environment and do not tolerate shade. Insufficient lighting can lead to the inability of begonias to synthesize chlorophyll, causing the leaves to turn yellow. If the temperature is high in summer and begonias are exposed to direct sunlight, their leaves may be sunburned and turn yellow.
Solution: Avoid exposing begonias to direct sunlight during hot summer weather. When moving begonias indoors for insulation in winter, make sure to place them in a sunny location, not in a dark corner.
<3, Unsuitable temperature>
Begonias enjoy growing in a semi-shaded environment. When the temperature is too high or too low, it can lead to the yellowing of begonia leaves.
Solution: During hot summer weather, take effective measures to provide appropriate shade, such as moving them to a cool, well-ventilated indoor area. In winter when the temperature is low, place them in a sunny position to receive more light.
<4, Improper watering>
What to do when the leaves of begonia turn yellow
When the temperature is high in summer and begonias are in a dormant period, excessive watering can lead to yellowing leaves, and even leaf drop and stem withering. The entire root system may rot, ultimately causing the whole plant to die. Insufficient watering and lack of moisture can also cause leaves to turn yellow.
Solution: When watering, keep the soil moist but not waterlogged. Control the amount of water and ensure the plant maintains moist soil. If watering is excessive, promptly add more water, being careful not to let the potting soil become severely waterlogged.
<5, Improper fertilization>
If fertilizing begonias too little, insufficient nutrition can lead to yellowing leaves. If fertilizing too much, it can cause fertilizer burn and result in yellowing leaves. During the dormant period in summer, excessive fertilization can also cause leaves to turn yellow.
Solution: If fertilizing too little, increase the amount of fertilizer. If fertilizing too much, water more and pause fertilization, while a lower amount of fertilizer can be increased. Usually, master the amount of fertilizer and avoid over or under-fertilizing.
<6, Pests and diseases causing leaves to turn yellow>
When growing begonias, pests and diseases often occur. For example: aphids, spider mites, and rust diseases. If not effectively controlled, they can lead to yellowing leaves and even root rot.
Solution: When pests are detected, use 70% imidacloprid water dispersible granules 5000 times solution or 5% lambda-cyhalothrin emulsion 800 times solution. For diseases, use specific medications such as 12.5% myclobutanil emulsion 600 times solution for spraying.
