Hydrangeas are great plants for the garden whose many benefits have been well recognized by gardeners over the centuries. They provide floral and occasionally foliar interest beginning in late spring or early summer that often persists well into autumn.
Hydrangeas are very popular shrubs that most gardeners love growing for their huge colorful flowers. Hydrangeas require well drained soil that is nutrient rich and lots of moisture. We always recommend adding a layer of mulch around hydrangeas to help retain that moisture and add more nutrients back into the ground. Some hydrangeas also require a little protection in the winter in order to bloom the following year. These requirements are things that you should look for when determining what to plant with your hydrangeas.
