Why Are The Leaves On Hydrangeas Withering?

Hydrangeas are a popular plant due to their large blooms and heavy flowers. However, they can also wilt due to various factors such as water stress, dry soil, excessive sunlight, over-fertilizing, flower growth, transplanting, and inadequate growing conditions.

Water stress is the most common cause for hydrangeas to wilt, as it can be caused by both overwatering and underwatering. Overfertilized hydrangeas may show wilting of lower leaves due to the presence of too many soluble salts in the soil that hinder water passage.

Insufficient water is the most common cause for hydrangea leaves, flowers, and stems to wilt. The name “hydrangea” comes from the Greek word “hydros”, meaning water. When fibrous roots don’t find enough water to take up, the hydrangea loses its turgidity.

Dehydration, excessive sun exposure, or nutrient deficiencies can also cause hydrangeas to wilt. If your hydrangea has not been watered and appears to be drying out, the big leaves lose leaf moisture faster than the roots can absorb more soil moisture, causing a wilted/droopy look.

When hydrangeas are drooping, they often express their dislike of local conditions. Too much sun and not enough water lead to wilt, and heavy flowers can also cause wilting.

To fix hydrangea wilting, it is essential to evaluate the plant’s water, light, and nutrient needs. By addressing these issues early on, you can help your hydrangeas maintain their health and beauty.
