Now we have a good pallet for our project we are ready for the rest of our supplies. You will need 2 large bags of potting soil, the equivalent of 16 six packs of annuals, herbs, etc., 1 roll of landscape fabric, a staple gun with staples and sand paper.
Step two is to clean up your pallet. Secure any loose boards, remove loose nails, and sand bad corners or rough spots.Step three, wrap it up! First decide which side of your pallet will be the back when the pallet is finished and leaning up against a wall, fence, or is attached to a structure. You will cover the back, bottom, and sides with the landscape fabric. The easiest way to do this is put your pallet face down on the ground and roll out your landscape fabric over the back. Be sure to wrap all the way around the bottom and leave extra to fold under. Starting on one side, fold under your edge about one inch and start stapling across. Once one side is complete, pull taunt and do the opposite side the same way. Once that is done, go back and secure all the sides so that the structure is completely covered and secure. Remember to also cover all the spines with staples (the slats along and across). You are making one-sided pockets to plant in and you will not want potting mix or your plants shifting in the spaces.
Final step, patience! You will want to leave your pallet down flat for a couple of weeks, watering as needed to ensure the roots develop and imbed the plants in place. Then set upright and enjoy your vertical garden!
