Two Main Groups
Location
- Bigleaf hydrangea prefers morning sun, afternoon shade and moist, well-drained soil. Avoid planting it on hot, dry, exposed sites. Cold damage to the buds may occur in winter and late spring, so be prepared to provide some winter protection by covering the plant with an old sheet, blanket or cardboard container when temperatures drop below freezing...
