Culture Notes Since the deciduous Bigleaf Hydrangea blooms on large buds formed on previous season's growth, any pruning should be done immediately after flowering. Long popular as a florist's plant, Bigleaf Hydrangea performs well in moist, rich garden soil in partial sun to fairly deep shade, where it can grow 4 to 6 feet tall. Be sure that tree roots are not competing with the roots, since this will slow growth dramatically. Flowers are bluish in acid soil, pink in neutral.
