If your gardening area has rocky soil, you can choose to use what you’ve got and plant what flourishes in rocky areas or you can put in some elbow grease. If you want to grow any type of plant, you may choose to amend your rocky soil, construct raised beds so you can grow on top of your soil, or opt for a container garden. But if you’re going to work with what you’ve got, you must be sure the plants you choose will be capable of performing well in the rocky soil.

Hello,
I’m opening a resort and am wondering what would you recommend for privacy bushes. The only problem is the soil is fairly rocky and sandy. Anything you can recommend?
Susanne Ashland says
Jacob,
Smoke bush & magnolia, if planted together would create a wonderful mix of the dense soft dark reddish leaves with light grey bark and white of the magnolia flower and shapeliness of the tree.
Create something beautiful too.
I don’t know what sort of scale of privacy you are trying to create, and hope you are still interested in someone’s thoughts on this topic.
Plants are my therapy and dirt is a good thing!
