Non-Chemical Management
- Plant in an appropriate location--hydrangeas prefer light shade and moist, well-drained soils.
- Provide proper watering and nutrition. Excess fertilizer, particularly during hot weather, can result in leaf damage.
- Improve drainage in soggy soils, or plant on a berm to improve drainage. Overwatering or soggy soils can damage the roots' ability to take up water.
- Examine stems for damage from string trimmers, cankers, or other injury.
- Use a layer of organic mulch over the root zone to retain soil moisture and to moderate soil temperatures.
- Do not apply herbicides near susceptible ornamentals or when drift is likely to occur. Use special care when applying broadleaf weed killers to turf near ornamental plantings.
