What Causes Hydrangea Petals to Wither
A brief knowledge sharing with you about the reasons for the withering of hydrangea petals in plant cultivation, let's learn about it together.
What Causes Hydrangea Petals to Wither
Hydrangea petals may wither due to prolonged exposure to rain, so it is necessary to protect the hydrangea from rain in its maintenance. Improper nutrients and lighting provided during maintenance can also lead to the withering of hydrangea petals. The plant may also experience petal withering during growth if it suffers from diseases.
1. -- Prolonged Rain Exposure --
Hydrangeas are not suited for rain exposure. If the plant is exposed to rain for extended periods during its growth, the petals can become contaminated by the rain, resulting in withering and yellowing. Therefore, during the flowering period, it is necessary to move the plant to a rain-free environment or take appropriate measures to shield the hydrangea from rain.
2. -- Improper Fertilization --
Hydrangeas require nutrients during their growth, but if fertilizer is directly applied to the flower buds, it can cause the petals to burn and wither. Therefore, during the later stages of hydrangea maintenance, it is necessary to dilute the fertilizer in water before providing it to the plant, allowing the hydrangea to absorb adequate nutrients.
3. -- Insufficient Light --
Hydrangeas thrive in environments with ample sunlight, but excessive light can cause the petals to be scorched and wither. Therefore, during later maintenance, it is necessary to provide the plant with appropriate lighting and also shield the hydrangea from intense sunlight to ensure better growth.
4. -- Affected by Diseases --
Hydrangeas may also experience petal withering if affected by diseases during growth. Therefore, it is necessary to regularly spray sterilizing agents on the hydrangea to eliminate bacteria and also ensure proper ventilation and air circulation to promote healthy growth.
The above content covers the reasons for the withering of hydrangea petals. I hope it can help you, and at the same time, I hope everyone comes to see more green plant and flower experience knowledge!
