Troubleshooting
Dwarf Serbian Spruce problems — and how to fix them
Dwarf Serbian Spruce (Picea omorika 'Pimoko') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Spruce spider mite (Oligonychus ununguis)
Stippled, dull needles and fine webbing in hot dry summers indicate mite infestation; tap foliage over white paper to confirm. Treat with a registered miticide; repeat after 10–14 days and improve moisture levels around the plant.
Frost pocket damage
Despite strong overall hardiness, 'Pimoko's' new spring growth is tender and susceptible to late-frost blackening; avoid planting in frost hollows or north-facing low-lying spots where cold air pools.
