Non-Chemical Management
- Choose the proper planting site. Most hydrangeas prefer morning sun and some light shade during the hottest part of the day. Do not place in locations susceptible to very early or very late frosts.
- When necessary, prune in winter or very early spring, before buds begin to swell. Remove up to 1/3 of the oldest growth, including thin, weak, or damaged stems.
- Removing old flower heads after flowering is completed will help control height and improve appearance of the plant.
