Troubleshooting
Creeping Juniper problems — and how to fix them
Creeping Juniper (Juniperus horizontalis) 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
A fungal disease causing shoot tip dieback, often starting at branch ends. Worst in wet springs. Prune out affected shoots well below the infected area, sterilising tools between cuts, and improve air circulation.
Spider mites
Hot, dry conditions encourage spider mite infestations, causing foliage to appear dusty and bronzed. Blast plants with water or apply horticultural oil. Ensuring adequate soil moisture reduces plant stress and susceptibility.
Root rot in heavy soil
Planting in clay or poorly drained sites quickly leads to root rot and plant collapse. Always amend compacted soils with grit or plant on raised ground. There is no cure once advanced — prevention is essential.
