One best way is to use Suspended Garden where you can use threaded stainless-steel rods through Terra-cotta pots and suspend them horizontally from the surfaces. This will save a lot of space and adds additional benefit in restoring the space. You can also make use of an Old ladder at your home by just painting it with a good color and arranging it with beautiful pots and #planters. It also gives you space to store garden tools and soil. If you are looking out for a vertical garden then you can go for Pocket Plants where you can have one or more pockets for your herb plants on any vertical surface of your outdoor space.
