Step 8 The Soil

It's important to have a light weight, well draining potting media, I've hopefully accomplished this by combining equal parts commercial potting soil with perlite, with the addition of a slow release fertilizer, following label directions. The soil is spread into the box using care not to compress the media, moistening it to keep it in place. I used 6 cubic feet total planting media.
