This is how to make a vertical garden design for planting a tower of herbs or flowers at home. It is a great space utilization idea. The idea is pretty simple and flexible. You just stack some pots together to make a tower. You can modify the idea to fit.
Border columns made with wood post placed in flower beds close the walk are beautiful, add lots of interest to the garden Place a big container of pretty flowers on top of the post. maybe could use pvc pipes w flower basket set on top?
