The first pic is a granny smith apple tree...originally i was told it had cedar rust, i sprayed it with a fungicide....now its back not looking good, not sure whats up with it... img 2692

The next pic is a plum tree which appears to be just being burned by the sun? or is it something different? img 2693

Next is a Cherry tree which im wondering if its the same issue with the apple tree? img 2694

Ive noticed on another cherry tree and one of my grapevines the same type of problem. Does my whole property have a fungus issue???

When i bought the fungicide they make it seem like you spray in the fall or spring, what about the meanwhile? Do you just let the fungus have its way with your plants?

I don't think they look so bad. Is there a term for hypochondria about your plants?

First picture: Not too familiar with specific tree diseases, but if it feels powdery, I would think it is a fungus. If the spray worked the first time, I would spray again. If it didn't work, try another kind of spray. I would also take off the heavily infected leaves and dispose of them far, far away from your trees, and rake up and take away any leaves on the ground.

Second picture: I agree, looks like sunburn.

Third: Hard to tell in this picture. The physical damage looks more like weather or insect to me. I might see some black spot under one leaf. If your first tree has fungus, it might be a good idea to spray other trees close by as well.

Fourth and fifth: could be white spot: https://extension.umn.edu/plant-diseases/raspberry-leaf-spot also a fungus. I would remove and dispose of infected leaves and spray the remaining leaves with your fungicide.

One spreading shoot is normal for a young raspberry. Staking it up off the ground might give better airflow and reduce the liklihood of returning fungus.

Is it very humid where you are?

Both of these look like weather or insect to me.

I think the fall and spring guidelines are for preventative maintenance. If your trees show fungus, spray as needed.

Fungus is everywhere. Most of my plants have had some problem their first year, then flourish after that. It's a big change going from the nursery to the real world. It's hard not to worry about them, but as long as there is healthy new growth they should be fine.

A berm makes a great wind break. And we all like to break wind once in a while. Like this tiny ad:
