I created the mix with 3 parts perlite, 3 parts peat moss, 2 parts Portland Cement and enough water to make it the consistency of cottage cheese.
All of the boxes are lined up and ready to go!
Shane brought me one of his Apollo Wheat beers to help the process...
First you fill the bottom of the big box, and then put the smaller box centered on top of that and fill in the space on the sides. Some recipes recommend using a piece of chicken wire in the bottom to reinforce it, but after trying this with the first two I made a month ago, it seems unnecessary with these smallish planters.
Voila! The finished product has to sit and cure for a couple of weeks...I cover them with some of the plastic sheeting so that they do not dry out too quickly.
