What Causes Hydrangea Leaves to Turn Black?
Hydrangea leaves may turn black due to excessive watering during plant care, leading to waterlogging and root rot, or due to excessive nutrients provided during care, causing plant burn. It could also be that the soil in which the hydrangea is planted is not suitable for plant growth, leading to poor plant growth and blackening of the leaves.
1. -- Excessive Watering --
Hydrangea leaves may turn black due to excessive watering during plant care, which causes waterlogging at the plant's roots. Therefore, when caring for hydrangeas later on, it is necessary to provide the plant with an appropriate amount of water, moistening all the soil, to create a relatively humid growing environment for the plant to thrive.
2. -- Over-fertilization --
Hydrangea leaves may also turn black due to excessive nutrients provided during plant care, leading to fertilizer damage and preventing normal plant growth. Therefore, when caring for hydrangeas later on, it is necessary to provide nutrients to the plant in a reasonable manner. It is best to mix the fertilizer with water evenly before providing it to the plant, allowing the plant to absorb sufficient nutrients.
3. -- Insufficient Light --
Hydrangea leaves may also turn black due to insufficient light during the plant's growth, leading to poor plant growth. Therefore, when caring for hydrangeas later on, it is necessary to provide the plant with suitable light, allowing the plant to perform photosynthesis normally. And when providing light to the plant, it is important to pay attention to the intensity of the light to avoid burning the plant with strong light.
4. -- Unsuitable Soil --
Providing unsuitable soil for hydrangeas when planting can also cause the plant's leaves to turn black. Therefore, when caring for hydrangeas later on, it is necessary to replace the soil for the plant. It is best to provide a sandy loam soil rich in organic matter and good drainage, and the soil should be turned over before planting to improve soil aeration.
The above is some experience about the reasons why hydrangea leaves turn black in green plants and flowers, hoping to bring you help in your daily life!
