I've had a fairly mature peach tree (I planted in 1996) that seems diseased or sick. I'll list some of the symtoms and my actions over the last year to attempt to get this tree to thrive. - most of it's branches have died (+ 80%) where the leaves turned yellow first resulting in the whole branch dying afterwards. - dying branches had sap forming on the underside of the branches with some patterns of the bark broken or split open - a few (1-2) holes on each dying branch that appeared to be insect made, I did notice a small number of ants on the tree but the number were very small - could this be |
