Fagus sylvatica 'Purpurea' problems — and how to fix them
Fagus sylvatica 'Purpurea' (Fagus sylvatica 'Purpurea') 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.
Loss of purple colour
Foliage greens or dulls in too much shade; site in full sun to maintain the deep purple-copper pigment.
Waterlogging dieback
Roots rot in heavy, wet soil, causing branch dieback and thin canopy. Plant only on free-draining ground and avoid compaction.
Beech scale and woolly aphid
White woolly patches on bark or leaves; heavy infestation can predispose to beech bark disease. Tolerate light cases; treat severe ones.
Leaf scorch
Hot, dry winds and drought brown the leaf margins, especially on young trees. Mulch and water deeply during prolonged summer dry spells.
