Can raspberry endless summer grow in full afternoon sun?

It depends on the location of the garden! Since you have a zone 5 garden, hydrangeas are generally fine in full sun. As it gets acclimated to a new home, your Summer Crush Hydrangea might need extra water to help it handle the hot afternoon sun. Keep an eye on it and plan to water every few days while it gets settled in and the roots become established. The Endless Summer Hydrangea planting and care guide has additional tips to help you grow healthy hydrangeas.
