Fertilization and Bloom Color Control +Book Signing with Joan Harrison
Hydrangeas require very modest amounts of fertilizer but only the right NPK ratios should be used. Bloom color is controllable to a great extent in the species H.macrophylla if done correctly. On Tuesday, July 10, join local author, Joan Harrison, as she shares the best methods for achieving vibrant bloom color. Her book, Heavenly Hydrangeas will be available for purchase and for signing.

All programs are free with museum admission.
