What Causes Hydrangeas to Turn Black?
The editor provides you with an introduction to the reasons why hydrangeas turn black, which will surely help you. Let's learn about it together!
What Causes Hydrangeas to Turn Black?
Hydrangeas turning black may be due to prolonged exposure to rain during their growth, or insufficient nutrients or sunlight provided during the care of hydrangeas, leading to poor growth of the plants. It could also be due to diseases during the growth process, preventing the hydrangeas from growing normally.
1. -- Prolonged Exposure to Rain --
The flowers of hydrangeas grow at the top of the plant, and when they are rained on, water accumulates in the flower buds, causing them to turn black. Therefore, during the later stages of caring for hydrangeas, appropriate measures should be taken to protect the plants from rain. It's best to place the hydrangeas under the eaves or on the balcony during rainy days to ensure healthy growth.
2. -- Affected by Diseases --
If hydrangeas are affected by diseases during their growth, they will show signs of turning black. In this case, appropriate pruning is needed, removing the blackened parts of the hydrangeas. It is also necessary to trim the dense branches and leaves to improve ventilation between the plants. Additionally, a fungicide should be sprayed regularly to eliminate bacteria on the plants.
3. -- Improper Fertilization --
Hydrangeas thrive in a relatively fertile environment, but if fertilizer is applied directly to the flower buds during feeding, it can cause the hydrangeas to burn and turn black. Therefore, during the later stages of caring for hydrangeas, it is necessary to provide nutrients to the plants in a reasonable manner, preferably by adding fertilizer directly to the soil.
4. -- Insufficient Sunlight --
If hydrangeas do not receive enough sunlight during their growth, they may exhibit poor growth and blackened flower buds. Therefore, during the later stages of caring for hydrangeas, it is necessary to provide the plants with ample sunlight to allow them to perform photosynthesis normally, and to provide timely shading when the sunlight is too strong.
The above is an explanation about the reasons why hydrangeas turn black, hoping to bring a little help to your life!
