Fagus sylvatica 'Dawyck' problems — and how to fix them

Fagus sylvatica 'Dawyck' (Fagus sylvatica 'Dawyck') 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.

Waterlogging and root rot

Beech roots are shallow and intolerant of wet, compacted soil, leading to decline and Phytophthora root rot. Plant only on free-draining ground and never overwater.

Beech bark disease

Beech scale insect plus Nectria fungus can cause bark cankers and dieback on stressed trees. Keep trees vigorous and avoid bark wounds; remove badly cankered limbs.

Drought leaf scorch

Shallow roots make beech sensitive to dry spells, browning and crisping leaf margins. Mulch generously and water deeply during prolonged drought.

Aphids and woolly scale

Beech woolly aphid and scale produce white waxy fluff and honeydew on shoots and bark. Usually tolerable; encourage predators and avoid over-feeding with nitrogen.
