Does a hydrangea need ground cover?

Whether you decide to use ground cover on your hydrangeas is totally up to you. If you decide to go for it, just make sure you pick the right plants and take care of them like you're supposed to.

I'm thrilled to share that, in my experience, hydrangeas really don't require any ground cover!

I don't think it's necessary.

Nope! Incrediball hydrangea doesn't need a round cover, but you can add mulch to help it retain and control weeds.
