Need advise on situation with numerous fruit plants
First of all hello to all, I'm new here as a poster but been lurking around gardenweb for a while now. Finally gathered up to register and post in this knowledgeable community
So anyways, I decided to plant some fruit plants this year and went out on a shopping spree. Everything was going pretty good until now, my two peach trees and a plum both started to loose leaves rapidly, same story with 3 muscadine grapes.
It looks like perhaps some kind of a fungus attacking all of them but I am no sure since I am not positive at what time of the year all of them drop their leaves for the winter.
So if anyone could help figuring out if anything is going wrong with my plants that would be great! I really do not want them to die their first year lol.
Also, would it be wise spraying them with copper solution either way for the winter? Can I pretty much spray everything I have to protect from fungus?
The other plants I have are: 4 blueberry bushes (1 that was the "strongest/biggest" is doing so-so, see pictures), kumquat, surinam cherry, kiwi, blackberry(also has some yellow leaves), raspberry, two pineapple plants and a pomegranate.
What other sprays would I need to keep them all healthy besides fertilizer?
Thanks for all the help in advance!
