Q.Hhydrangea bush
I transplanted my bush about 2 years ago, but it doesn’t get any bigger. It has leaves and produces one flower; what can I do?
Make sure you have the Hydrangea planted in an area that receives full sun or partial shade. If you are in a warm climate, you may want to have morning sun and afternoon shade.
