Why Isn't My Hydrangea Blooming?

A 2–3 year old hydrangea in part sun/shade isn't blooming or growing much. Common reasons: improper pruning (some hydrangeas bloom on old wood—prune only after flowering), late frosts killing buds in cold climates, alkaline soil (hydrangeas prefer acidic soil—amend with Miracid or sulfur), and insufficient water in dry areas. Stop pruning, ensure weekly watering, and test soil pH.
