What causes the leaves of geraniums to turn yellow
Here are some small gardening tips to answer netizens' questions about why geranium leaves turn yellow. Let's take a look together.
Why do geranium leaves turn yellow
Geraniums are a great decorative flower. So, what happens when the leaves turn yellow during the care of geraniums? Today, let's find out.
Reasons for the yellowing of geranium leaves: Low temperature
Geraniums prefer a warm growing environment, suitable for growing in temperatures between 15 and 20 degrees. If the temperature drops below 0 degrees, the leaves of the geraniums can be frostbitten, leading to yellowing. Therefore, when caring for geraniums, we need to maintain the temperature, especially in winter, when we need to take preheating measures in advance to prevent frostbite.
Overwatering
Geraniums prefer a dry growing environment and are particularly afraid of waterlogging. Therefore, we should not water them frequently when caring for geraniums. Excessive watering can easily cause waterlogging, which can lead to root rot in geraniums, causing the leaves to turn yellow. When watering, we need to wait for the soil to dry out completely before watering, avoiding waterlogging.
Insufficient lighting
Geraniums require a sunlit environment for care. If there is insufficient light, geraniums cannot photosynthesize effectively, leading to a decrease in the chlorophyll content in the leaves, which can cause the leaves to turn yellow. Therefore, when caring for geraniums, we need to ensure adequate lighting. In the summer, when sunlight is strong, we need to shade the geraniums to prevent leaf sunburn.
