Hello everyone,
Recently I have seen that some leaves on a few of my pear trees are starting to yellow. It seems to start at either the edge of the leaf or in the middle. I am located in Maine and we have had a cool/wet spring and early summer. I have searched earlier posts but have not come upon anything quite the same (though I may have missed one and if so please just direct me to that to save everyone time and trouble). What research I have done lists possible causes as lack of iron, lack of nitrogen, or possible too wet soil? Has anyone else come across this and have a possible solution? Thanks to everyone in advance for giving any advice.
-Jerry
