Troubleshooting
Shore Juniper problems — and how to fix them
Shore Juniper (Juniperus conferta) 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.
Phomopsis blight
Fungal dieback affecting shoot tips and branches, most prevalent in wet spring conditions. Prune infected shoots back to healthy wood in dry weather, sanitise tools between cuts, and improve air circulation with wider spacing.
Spider mites in dry inland conditions
Hot, dry, non-coastal sites promote spider mite outbreaks, causing stippled, bronzed foliage. Regular misting or overhead irrigation can reduce populations; horticultural oil applied in early spring is effective.
Root rot from poor drainage
Despite salt tolerance, Shore Juniper is intolerant of waterlogged soil. Planting in clay or low-lying sites leads to rapid decline. Always plant in well-drained locations or raised beds; there is no recovery from advanced root rot.
