Prince of Wales Juniper problems — and how to fix them
Prince of Wales Juniper (Juniperus horizontalis 'Prince of Wales') 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.
Tip blight (Phomopsis/Kabatina)
Browning shoot tips in damp weather; prune affected growth, boost airflow and keep foliage dry.
Root rot
Poorly drained or clay soils rot the roots; plant on raised, grit-amended ground for sharp drainage.
Thinning in shade
Insufficient sun produces a sparse, patchy mat and weaker winter colour; site in full sun.
Spider mites
Bronzing and fine webbing appear in hot, dry spells; hose down regularly and use horticultural oil for serious cases.
