Troubleshooting
Blue Arrow Juniper problems — and how to fix them
Blue Arrow Juniper (Juniperus scopulorum 'Blue Arrow') 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.
Snow and ice damage
The slim column can splay or break under snow load; knock off heavy snow or tie loosely in winter.
Tip blight
Phomopsis browns shoot tips in wet weather; prune affected growth and improve air circulation.
Cedar-apple rust
Acts as an alternate host, forming orange galls that infect nearby apples and crabapples; remove galls and avoid planting near pome fruit.
Root rot
Wet, poorly drained soil rots roots and kills the plant; ensure sharp drainage or raise the planting bed.
