If this photo is from the northeast, what you are likely seeing is cherry leaf spot which is normal for cherry trees not sprayed with fungicide.

That is good to know, so there is still hope for them lol. I did see some sticky sappy substance coming out of a few which worried me as well. You got my location bang on....nova scotia.

Yes, it looks like cherry leaf spot to me, which can be serious unless you spray for it. I almost lost my two trees to it until I discovered which fungicides work for me. Captan did nothing for it. Then last year I alternated Ortho garden spray, T-Methyl, and Rally . Then just Rally this year. My cherry trees are now the healthiest looking trees in my orchard.

When does one spray cherry trees? Fall? I really need a second cherry tree.....do dwarf cherries pollinate tree? I ask this because I saw a small dwarf cherry but was unsure if it would pollinate my tree.by dwarf I mean a small plant about as big as a raspberry bush they sell at nurseries.....it was not a tree. But it was prunus.....I have never sprayed my cherry tree at home, and it looks great, should I be spraying?
