Hi,
I am not sure if this query should be in bug-by-bug or fungal pathogens:
on the majority of my trees (third year) a lot of the leaves are curling down from the tip back to the stem.
The tip and sides of the leaves are turning brown and are crisp to the touch.
I see no evidence of any type of catepillar or curling midges (not saying they are not there however).
There are some lime green aphids but not a lot and I see no eggs or farming ants about.
Any ideas as to what might be the cause? Thanks
