Why Have My Hydrangea Leaves Turned Black？
Hydrangeas are beautiful flowering shrubs that can add a touch of color to any garden. However, sometimes hydrangea leaves can turn black. This can be a frustrating problem, but it is usually not a deadly one. Below are some of the most frequent causes and how to fix it.
1. Overwatering: This is one of the most common causes of black hydrangea leaves. Hydrangeas like moist soil, but they do not like to be waterlogged. If you overwater your hydrangea, the roots can rot and the leaves will turn black. To fix this problem, simply reduce the amount of water you are giving your hydrangea.
2. Nutrient deficiency: Hydrangeas need a lot of nutrients to thrive. If your hydrangea is not getting enough nutrients, the leaves can turn black. To fix this problem, fertilize your hydrangea with a balanced fertilizer.
3. Disease: There are a few diseases that can cause hydrangea leaves to turn black. One of the most common is botrytis blight. This disease is caused by a fungus that thrives in moist conditions. To prevent botrytis blight, make sure your hydrangea has good air circulation and avoid overwatering.
4. Frost damage: Hydrangeas are not cold-hardy plants. If they are exposed to frost, the leaves can turn black. To prevent frost damage, protect your hydrangea by wrapping it in burlap or covering it with a tarp.
5. Sunburn: Hydrangeas need sunlight to grow, but too much sunlight can scorch the leaves and turn them black. To prevent sunburn, plant your hydrangea in a location that receives partial shade.
