Sterilization: Cuttings, soil etc
Was watching a video on Strep propagation where the fellow was sterilizing everything-include the cut leaves. Those he sterilized in bleach (one part to five parts water I believe) and water.
How absolutely necessary is it to sterilize everything? Just trying to understand the ramifications if I don't. The potting mix I use does also contain some Styrofoam balls (not perlite), so I wouldn't be able to microwave or oven bake it to sterilize. Do I need to get a different mix?
Thanks for any insight-
