Are you growing vegetables there? Against a wall in the summer can be brutal with the reflected heat. An organic mulch would make the area look better and help keep the soil cooler but hopefully its morning sun only exposure.

This is easy to make this a colorful and cute focal point. Chili peppers and succulents are good together in pots or in the ground. You need a little height and some taller pots could provide shade for plants around it.

Stack some bricks taller as a cute plant stand.

Amend and level out the soil.

Clean the rocks and arrange them in a curvy border partially on the turf.

Place your pots first and plant your vegetables around them.

Don't forget seasonal flowers..easy to change out.
