This is my first post so please bear with me. I have had my dwarf peach tree about 6 years and have had two great yields(especially last year). This year we had three days of below freez ing temps and I thought I had lost the tree. However, after about two weeks some nubs began to show and low and behold I had a tree filled with peaches. I contunued with my sprying routine that I have used for years from virginia Tech, However, I have had to find an alternative spray(one year a concentrate liquid and this year some old Dragon fruit tree spray that I bout in a close out sale for $5.00 each). the peaches coninued to mature for the next month. Suddenly, the fruit has stopped maturing and the tree looks very stressed and I think I'm losing the tree. Many of the leaves fell off but there is still some sigh on growth but not much. I have Red Haven right beside it and its doing great and looks like I'll get a good yield from this three year old tree. My question is: Have I done something to damage the tree with the new powder spray(Dragon) or is the life expectancy of a dwarf peach tree short. A side note: I did spray some weed-be-gone underneath the tree to kill a lot of the weeds. Orchard spray( a powder spray company that doesn't seem to make their product anymore is what I used to use but I can't find it anywhere). Any info to help answer my delima would be appreciated.
