sick cherry - what should I do ?

13 years ago

Due to extremes in temperature I tried to collect whatever I could find (wild oregano, grape vine, dry grass) on the adjoining piece of land to use as mulch. Unfortunately, I may have picked up some grape vine whose leaves had brown spots on them - not sure if this is what has led to the problems with my cherries.

Before this, I had sprayed everything around my house a few times with aerated vermicompost , all watering was done at ground level and everything seemed OK.

Issues:
- small cherry with yellowing leaves with brown spots which are falling of + gumming in spots
- large cherry with yellowing leaves with brown spots which are falling of
- small sour/sweet cherry with leaves with black spots.

All I could think of was to use something anti-fungal, so I sprayed a bit of copper-blue mixed in water.

Can anyone confirm whether my diagnosis is correct :
-yellow leaves with brown spots = Cherry leaf spot,
-gumming = bacterial canker,
black spots on leaves = ?

What else can I do now / what should I do in the future
(maybe it would be wise to remove the mulch)
using what is as natural/organic as possible ?
