Of the 2 Hawthorn I collected last year my favorite pick did not make it through the winter. The other did wake and is doing pretty good until this weekend I see yellow spots on many of the leaves. The pictures do not show the spot very well but it is showing throw to the underside.
Any idea what I need to treat this with...

Thanks

Probly Cedar Apple Rust.

I plucked and Quarantine trashed all effected leaves early spring lay year and remained clean ....

Buckthorn Hawthorne rose apple Crabapple eastern red cedar....

All Safe....chem free....

Get plucking...slowly, carefully, totally, and you should be ok.

This is ONE stage...

The balloony orange wormy fruits and ERC chunks is another stage....

If you have both stages...
You have to get rid of the rest too...

I think those other stages are more prone to releasing babies....
But I try not to shake any of em.

Thanks sorce, been busy and did not get back to this. I had time to check the tree this weekend and it seemed to be about the same, not many more leaves. I was about to take a picture and then remembered I already had... yeah ... been that busy.
I will do some plucking tomorrow, should be home before dark.
