Can you post pictures of what you're calling scab?

I ask because apples & pears get scab. Peaches don't.

As for the lack of pollination with your BT, getting another BT won't do it. Needs to be a different cherry. Most likely someone with that knowledge will chime in.

Scab can show up on peaches, but on the fruit itself. I have never heard of scab affecting the overall health of a peach tree. You can start by either posting a photo, or giving us a good description of what you believe to be scab. It wouldn't hurt to tell us where you live.

Northstar is a tart cherry that requires no companion pollinator to set fruit. My personal advice would be to forget trying to grow sweet cherries. They are just too difficult for a whole host of reasons.

I live in north east Ohio. I had peach scab on the fruit last year and thought it might be happening again. But if peach trees do not get it then I wonder what I got. The new growth is covered in the same black spots that the fruit had last year. I will take a picture of it and post it later on today.

As for the sweet cherry question, I will try a different pollinator. Sorry I'm stubborn and cherries are great :>)

Somedude:

Leaf spots probably indicate bacterial disease, which can affect the leaves, the wood, and the fruit. It is very common on peach trees in the east. Since I began dormant spraying with Kocide copper, I have not seen this disease on my trees, but I don't know whether that is a cause/effect relationship. Once bacterial disease is underway during the growing season, I know of no way to stop it.

It great to be stubborn and determined to grow the fruits you like, but I am afraid that after about 10 years of trying you won't be quite so stubborn with sweet cherries. They are a great fruit, and if I lived in California I would be growing them.

Hi jellyman,

That is the conclusion that I came to. It is brown spot/peach scab. I did some google Fu and found that that is what my 1 year old tree had. Now I got a 3 year old Peach tree that has it now! (well it's not covered like the 1 year old) I know peach scab does really nothing to the fruit but it irritates me! >:>( I'm going to try something my aunt told me. She says take baking soda, mix it up and spray it on the tree. She says that the higher PH of the baking soda with kill off the fungus that loves acidic ph levels. It kind of makes sense. Anyone ever hear of this?

Stupid diseases.....

Oops. I didn't realize that peaches get a scab. In my region, pears & apples get it. Hmm. Live and learn.

But it's a different fungus. (So I was part right. Right? sigh)
