A buddy of mine told me about Lime and Sulfur for fungus on tree's and shrubs. I have a peach tree that is damaged by leaf spot. The fruits are twisted and the leaves have many black spots all over them. The customer wants to save these tree's. What is the best procedure to use when applying an organic fungicide such as Lime and Sulfur? Should it be applied with an organic oil such as Natur'l Oil or just alone? How many times should you apply a product like this to be most affective? Also, I have seen a lot of apple tree's and other leafy bush's like Amelanchia Grandafloria "spelling," having like a blister. Looks red on one side and then almost like a pimple looking blister on the other side. These blister's are usually yellow. In general if the plant was planted correctly what could be done to help these plants using natural products? I have recently ordered from Groworganic.com, Neem soap, Hexan, Natur'l Oil, Cold pressed Kelp, Fossilized sea dust, Lime and Sulfur, and Hemp gloves ~ Any techniques that can be shared to optimize the use of these products would help.
