@sooby Sue, except for herbs and onions, I have not grown fruits or vegetables in 35 years. So I hesitate to tell a fruit or vegetable gardener anything. But I saw the blight and wanted to start Terri on the right path, and give an option.
That being said I have lots of crazy fungus that appears here. I would spray with baking soda mixture all surrounding plants for prevention.The spores are there. Spray the soil where the plants were removed 3x in one day, then drench. So where you knew the spores were you especially do not want fungus spreading. Drenching first might spread spores. Sometimes I have directly sprinkled baking soda on a problem. After the other blight question, I did wonder about pH, soil and baking soda. I know after rain or water changes in a chlorinated pool you can add baking soda, that allows the other chemicals to work properly. That is a pH thing, so maybe the reason baking soda works in soil is a pH thing. If you think about it, lots of fungus will form after a rain which might have caused a temporary? soil change.
Baking soda works for me on fungus and southern blight and alot more. It might be my sandy soil that allows it to work so well. It also might be the large number of hot temperature days here. My soil solarizes on a regular day
. Now if I could just get all the weed seeds to I would be happy. Thank you, Sue for all the hard work you do for everyone
May everyone be blessed with successful gardening endeavors!
