I'm thinking how long I should wait to plant the limelight hydrangea?
I think a distance of about 3-6 feet is perfect for limelight hydrangeas, especially since they grow up and out as well as they do.
A distance of roughly 6 to 8 feet is definitely necessary for this plant; limelight hydrangea thrives in this environment.
It seems that a distance of 3-5 feet is very suitable and can help its growth.
