I have read that baking soda is considered a fungacide and it is ok to use on plants. Is this true? Can it be used on tubers when they have been separated. How about on lily scales separated for propagating? Thank you

Baking soda has some fungicidal qualities and it can be used on some plants but not all. If you decide to make a baking soda mixture, test it on a small part of your plant to see if there are any adverse reactions. To make: Mix 1 tablespoon baking soda, 2 1/2 tablespoons vegetable oil with one gallon of water. Shake this up very thoroughly. To this mix add 1/2 teaspoon of pure Castile soap and spray. Be sure to agitate your sprayer while you work to keep the ingredients from separating. Cover upper and lower leaf surfaces and spray some on the soil. Repeat every 5-7 days as needed. It won't work on tubers or lily scales, just the leaves and stems of plants.
