I have heard it is a good idea to add some organics ie manure/ worm castings etc to promix for growing in pots. How far before using it to transplant should this be done and what are some methods of doing this. I split a 3.8cu bale into three garbage bags for now and have worm castings and horse/chicken manure waiting. I hear its a good idea to increase the micro-organism population prior to transplanting ie creating live soil.
