Hello, Two questions about fruit trees: 1) What is the best non-toxic treatment for cedar apple rust? The tree is a Sweet 16 if that info is needed. 2) We planted a Reliance peach tree last spring. It looked to be thriving (full leaves, growth) last fall. This spring, it produced a couple of small green leaves that fell off in short order. It now is bare and appears dead. There is a small tree growing about 3" from the trunk. I am guessing it is a sucker. is there any possibilities to help that grow and also removing the dead tree (or at least sawing to a small stump)?

There are no effective fungicides available to gardeners to control this disease on fruit producing trees. You can scout, however, for the alternate hosts and see if you can remove the jelly like fungi. Here is information on Cedar Apple Rust http://www.extension.umn.edu/garden/yard-garden/fruit/apple-pest-management/cedar-apple-rust/

As far as your peach tree, look to see if the tree was grafted onto a dwarf root stock. There should be a 'bump' where the trunk was grafted. If the sprout is growing out of the trunk above that graft, you can remove the dead tree above it and all that to grow into a tree. If it is coming from below the graft, remove the roots and all.
