Crushing everything and to add the necessary colorants, insecticides and fertilizers. what products would I have to add for its better results. thanks

• Answer:

  Dry it first. Then use regular vegetable dye. Your ordinary insecticides and fertilizer you use for the flowers and garden plants will suffice, and the mulch will prevent evaporation and runoff. Depending on the mulch, you may need to measure ph every year, or estimate adding just a little bit of lime.
