Fertilization and Bloom Color Control

Tuesday, July 10: 1:30-2:30 + Book Signing with Joan Harrison

Saturday, July 14: 1:30-2:30

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.

On Saturday, July 14, Mal Condon, our Curator of Hydrangeas, will share his expertise on the critical factors associated with these two important cultural subjects.
