How many hours of sun can hydrangeas take a day?
The amount of sun a hydrangea can handle varies with different parts of the country. Hydrangeas in northern gardens can tolerate full sun, all day. In southern gardens, morning sun is best. In your zone 6 garden, your hydrangea would be best in a spot with morning sun and protection from the hot mid-afternoon sun. Take a look at the Endless Summer planting and care guide for additional tips on growing healthy hydrangeas.
