I have grown these apple tree samplings from seed but every year, just as the growing season gets going they start being effected by this white blight.
It resembles dew and causes the leaves to curl up and die.
The saplings are about 3 years old
This happens every spring
They are outside and receive sun/shade 50/50
Watered generously
Good air circulation
Repotted every year
Any help or suggestions on how to treat this would be really appreciated. So far I have been aggressively pruning the dying leaves to stop it seemingly spreading.
