Troubleshooting
Ophir Mugo Pine problems — and how to fix them
Ophir Mugo Pine (Pinus mugo 'Ophir') 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.
Poor winter colour
Insufficient sun, mild winters or over-feeding weaken the golden colour change. Site in full sun, expose to cold and feed minimally for the brightest gold.
Root rot in wet soil
Waterlogged ground causes root decline and browning. Plant in fast-draining soil, set slightly high and avoid overwatering.
Pine sawfly larvae
Larvae can strip needles quickly in spring; check new growth and remove or treat colonies before defoliation.
Diplodia tip blight
Browning, dying new shoots in wet seasons. Prune affected tips in dry weather, clear debris and avoid overhead irrigation.
