Troubleshooting
Holger's Juniper problems — and how to fix them
Holger's Juniper (Juniperus squamata 'Holger') 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.
Phytophthora root rot
Caused by overwatering or poorly draining soil; symptoms include yellowing foliage, wilting, and branch dieback from the base upward. Improve drainage immediately and remove affected tissue.
Juniper tip blight (Phomopsis/Kabatina spp.)
Fungal disease causing brown, dying shoot tips in spring or autumn; most common in wet seasons. Prune out affected tips, improve air circulation, and apply a copper-based fungicide if necessary.
Spider mites
Fine webbing and stippled, dull foliage in hot, dry summers indicate spider mite infestation. Blast plants with a strong jet of water or apply horticultural soap or neem oil.
