I've read similar concotion at an organic gardening web site. My concern is that where I live so close to the ocean and arid climate, any addition of sodium to the soil is not a good thing. sodium bicarb isn't all that different than potassium bicarb so I'm thinking maybe its the Na+ or K+ that's killing the mildew.
What's really interesting is that mildew is only affecting just small portion of my garden while the rest are healthy green. Sooo how can a strain of plant is free on one area and overwhelmed in another area.
Anyway, I'm going to be testing for NPK in the bad area and also in the good part. Maybe this will tell.
Oh potassium carb can be had at a local ceramic store under potash. Sodium carb is listed as soda ash. The difference between carb and bicarb in this application is their solubility I think. It's not the carb or bicarb that is killing the mildew.
anyway if you know more I would love to hear from you. I just the problem to be resolved.
