Got some milled 2-row malted barley to throw down as some mulch. Around 4 cups per pot but just thrown on by hand. Smell of barley is more pungent than the weed ever seems to get. I will be trying unsulphured blackstrap molasses at a rate of 1 tablespoon to 1 gallon in my water next watering. I am undecided how to use it and wether I want to test it out.
