Holly and Tee - Thanks to both of you! I am glad you and others like my pallet garden!
I hope other gardeners copy my idea. It really makes a great way to grow herbs and keeps their growth contained in one area! This vertical garden could also be used to grow strawberries! I may try that next year and then plant herbs after the strawberries are done. This could be used in various ways!
It could also be used as a garden screen to give some privacy to an area of your yard from nosey neighbors.
I have plans to turn the area behind it into a kind of bird blind. A lot of the birds use the Cassia tree, right next to this vertical garden, and it is partially shading the area behind the garden pallets. It would be very easy to sit quietly in that area with camera in hand and snap away as the birds fly in and perch on the branches. It is a perfect area to "hide and wait" for taking wildlife photos!
