Hydrangeas are glorious summer garden bloomers with so many varieties! They grow so well in the PNW that almost every garden has at least one. But how do you care for them? What can you add to soil to bring out the color you love most? What time should you prune them? Get your questions answered by our own Shade Garden Curator, Marylou Hart. Class held in the Arboretum from Noon to 1 PM. Meet at the Entrance Columns.
