Malus 'Profusion' problems — and how to fix them
Malus 'Profusion' (Malus 'Profusion') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Apple scab
Causes black leaf spots and premature defoliation; this cultivar has moderate susceptibility, so clear fallen leaves and keep the canopy open.
Fireblight
Bacterial blight that wilts and blackens blossom and shoots; prune well below infection and sterilise tools between cuts.
Powdery mildew
White fungal film on shoots in dry weather; remove affected tips and avoid water stress.
Aphids and woolly aphid
Distort growth and leave honeydew or white waxy colonies on bark; tolerate light attacks, which predators usually suppress.
