Container growing Hydrangea — a practical guide from experience
I don't have a garden so a wildlife garden with berrying and nectaring shrubs is my only option for Hydrangea. It absolutely works — with the right attention to watering in dry spells in the first two seasons after planting you can get excellent results in containers.
wide range from ground-covering species to large specimens is fully achievable even in a pot. early spring flowering on bare branches before leaves appear is just as impressive in a container as it would be in the ground, possibly more so because the plant is at closer viewing distance. The main issue to watch in containers: dieback from harsh winters on marginally hardy varieties. Happens faster than in the ground. Highly recommend for balcony and patio gardeners.
