Now that I've thoroughly mixed this medium which is about a third each of potting soil, topsoil and manure, I am going to take it over and we are going to put in a layer of it in preparation for fertilization and final planting. I am not going to put in all the way to the top. We are going to put in a layer and then we are going to fertilize the soil so that when we plant our plants, the roots will be right close to the fertilizer and ready to take it up. If we were planting seeds or cuttings like that, we wouldn't want any fertilizer in the root zone. Since we are going to be planting bedding plants that have established root systems and are actually growing plants, as long as we don't put too much fertilizer, fertilizing the root zone is a good thing. Cause some materials like phosphorous and pot ash are immobile in the soil so you have to have it so the roots can catch right away in order for the plants to get a jump start and be ready to go as soon as the roots take hold.
