Here is a photo of my little cherry tree. It's been doing ok so far but recently the leaves have been going yellow. It's not the yellow as if the tree is dying but there is something affecting the leaves. Too hot, too much/little water, viral, insects, fed up with life and wants to commit suicide, lonely and sad, ...... or what?
It looks a little like what happened when we put our bay laurel tree out in the strong sun for the first time - my dad calls it sunburn. It recovered when we shaded it a bit more. Does it get a lot of strong sun?
