Re: baking soda/ was jade plant- advice needed

Andrea and Theresa,

The way baking soda and water works is that it prevents fungal hyphae from invading a leaf surface. It's works well to prevent Powdery Mildew, and is quite useful, though you have to watch the soil pH if you use it a lot, or if your soil is already alkaline. I don't think it would be effective on a stem rot where the disease is probably already in the system.

The sulfur powder is a good alternative for some rots. It was commonly used by the old-timers to dust the cut surfaces of seed potatoes and various bulbs.

Remember to use disinfected knives/clippers or pruners and cut far enough so that you're into healthy tissue. Sometimes we kill plants by not taking off enough of what looks like "clean" tissue but is really infected, so we just prolong the agony.

Huh- wonder if it works as well just sprinkled on dry?

was told by an herb farmer yesterday that the best organic fungicide is the 1 tablespoon of baking soda per 1 gallon of water. Said it's great for everything. I knew that, but always forget it.
