Hey Banksia
That is a really nice Pom. I as some others experienced leaf curl distortion last year on various species. Even Street trees in my area where affected. Amur maple is first out as usual this year and all is looking good so far fingers crossed.
I also treated with lime sulfur during Winter at about 20-1 on the deciduous. I have seen this in my yard in previous years but it never caused the trouble it did last year. It will be interesting to see how the yard trees go this year as they have received no special treatment yet. Last year was reported as very bad for fungus and bugs in general with the seasonal changes.
We found a product called bravo worked well but it is not easy to get and is pretty toxic. I planned to give the better trees a preventative dose as they leafed out but am also considering the copper fungicides like Kocide Blue Extra.
I can't find much info about using these on broadleaf trees but it has been ok on privets so far.
Not sure Lime sulfur is a good idea to keep using now it is back in leaf but maybe it is ok at a weak solution.
I think if we where experts we would continue some preventative treatment after last year but I am no expert so I will leave that chioce upto you

Good luck!
Oh Yates Anti rot might be worth a try it is very safe and systemic. Don't think this can do any harm so might be the go for just a little insurance! I have been told you can not over do it with this stuff. Cheap too. Apparently you could bath in the stuff to no ill affect. Glad you reminded me

It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
