Troubleshooting
Blue Carpet Juniper problems — and how to fix them
Blue Carpet Juniper (Juniperus squamata 'Blue Carpet') 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 tip blight
Fungal browning of young shoot tips in wet weather; prune out affected growth, improve airflow and avoid overhead watering.
Root rot in heavy soil
The most common killer; soggy clay suffocates roots. Plant on a raised mound or amend with grit for sharp drainage.
Inner browning / shading out
If overcrowded or shaded, the centre thins and browns. Site in full sun and give it room to spread.
Spider mites
Cause stippling and bronzing in hot, dry, dusty spots; hose down foliage and treat heavy infestations with horticultural oil.
