Troubleshooting
Betula pendula 'Youngii' problems — and how to fix them
Betula pendula 'Youngii' (Betula pendula 'Youngii') 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.
Aphids and honeydew
Aphids on new shoots drip sticky honeydew that blackens with sooty mould beneath the dense crown. Encourage predators and avoid over-feeding with nitrogen.
Birch rust
Orange rust pustules and premature leaf drop appear in wet summers. Usually cosmetic; collect and dispose of fallen leaves to limit spread.
Rootstock suckers and reversion
As a grafted weeper, upright shoots from the rootstock or above the graft can spoil the form. Remove suckers and any vigorous non-weeping growth promptly.
Crowded crown dieback
The dense, ground-trailing canopy can hold damp and shade out inner growth. Thin congested branches and lift skirts off wet ground to improve airflow.
