How far apart should I plant my Endless Summer® hydrangeas?
Spacing your plants depends on the variety and your desired look. If you’d like to create a hedge, plant a bit closer together. And if you like some delineation of lines between the plants, you can add a little breathing room. Each variety also has a different size at maturity, so you’ll want to keep that in mind. For example, Summer Crush® hydrangea matures to 18-36” wide, so you’ll want to plant them roughly 36” on center to give them enough room to breathe. Having space for airflow helps prevent any disease occurrence on the leaves.
