What can I plant around my deck?

Depending how steep the slope. its a great place for a rock garden with low growing flowers and or foliage

Maybe some creeping junipers? There are a variety of colors, greens, blue-green, gold.

I think it's perfect for a rock garden. The slope is fairly minimal. It would be super nice to look over the sides of the deck and see the plants, rocks and novelty items such as metal frogs it even fairy garden. Good luck!!!!!

This is perfect for that type of garden since it looks like part of it isn't doing well in the shaded area. Check out Pinterest for more great ideas on rock gardens
