Potting media is a heroic player in the gardening game, especially when it comes to the success of your vertical garden or greenwall.
Even with the huge root space afforded by the Garsy vertical garden/greenwall system, if your greenwall plants are to have a long, luscious life, you need to make sure that you surround their roots in potting media which holds moisture well and retains all the nutrients.
A great watering system alone doesn’t guarantee success even if you irrigate like a pro. Cheap potting mix can quickly become hydrophobic (repels water) thus preventing the roots from accessing moisture and the nutrition they need to thrive.
Potting mix that is specially formulated for vertical gardens and greenwalls is now available at most nurseries but if you’d like a sure-fire, fuss-free recipe for making your own, you’ll discover the easy to find ingredients in chapter 3 of that little guide of Keri’s I mentioned in my last post.
