Plant, grow, and harvest all in one! This is a mix that you can place your veggies or flowers in and grow all season long. The bag will last one season reliably and up to 2 years if kept out of the sun. It is a good idea to use a little fertilizer mid-summer to give a boost to any plants. Worm castings, fish emulsion, or another natural product are recommended.  Tray is sold seperately
