I started growing fruit trees about 15 years ago and it was a disaster. Started with 3 cherry trees from Gurneys that all died after 2 to 4 years and apple trees that did nothing. About 5 years ago bought a peach tree from Lowes (it came from Dave Wilson) and it grew and finally produced peaches. I was hooked and over the last 3 years have bought about 7 or 8 peach trees with different varieties, With the exception of one tree I have had no blights/fungus etc. other than Japanese Beetle problems.
For the peaches I have read that it is good to use a Copper 2 to 3 treatments during the dormant stage and then use a fungicide starting with budding. Is this correct? What I the right mixture per gallon for the copper and what fungicide, mixture and frequency of application do people recommend?
Same question for Apple Trees, I have bought better varieties but Apple Cedar Rust is a bad problem where I live - Piedmont area, Virginia.
Any recommendations would be greatly appreciated.
