Why Do Hydrangea Seedlings Turn Black
Hydrangea seedlings may turn black due to improper watering during the care of the plant, leading to water accumulation and rot in the seedlings. It could also be because fertilizer was accidentally poured on the seedlings during feeding, causing them to turn black. Moreover, it might be due to diseases encountered during the plant's growth. Therefore, it is necessary to provide appropriate water and nutrients during the later care of hydrangeas to ensure the plant grows healthily.
1. -- Improper Watering --
Hydrangea seedlings turning black might be due to improper watering. Water can be sprayed on the plant to keep the environment moist or poured into the soil to keep it moist. However, spraying water on the plant during the sprouting process can lead to water accumulation at the seedling site, causing the seedlings to turn black.
2. -- Over-fertilization --
Hydrangea seedlings may turn black due to improper fertilization. Hydrangeas thrive in a relatively fertile environment, so it is necessary to provide the plant with proper nutrients during care. However, accidentally pouring fertilizer on the seedlings during feeding can lead to burning and blackening of the seedlings.
3. -- Excessive Sunlight --
Hydrangea seedlings are delicate when they first emerge and cannot withstand strong sunlight. If the light provided to the hydrangeas is too strong, it can lead to sunburn and blackening of the seedlings. Therefore, during later care, it is necessary to provide appropriate lighting and promptly shade the hydrangeas when the sunlight is too intense.
4. -- Disease Infestation --
Hydrangea seedlings turning black may also be due to diseases encountered during the plant's growth. In this case, it is necessary to immediately cut off the blackened part of the hydrangea and spray the plant with an appropriate amount of disinfectant. Also, during later care, it is important to ensure proper ventilation and aeration for the plant to improve the ventilation of the growth environment and allow the hydrangea to grow healthily.
