Troubleshooting
Compact White Fir problems — and how to fix them
Compact White Fir (Abies concolor 'Compacta') 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.
Adelgid (woolly aphid)
White woolly deposits appear at the base of needles. Treat with insecticidal soap or systemic insecticide in early spring.
Balsam woolly adelgid
Can cause gall formation and dieback. Monitor and treat promptly as infestations can be severe in some regions.
Root rot in wet conditions
Avoid planting in low-lying or heavy clay soils. Excellent drainage is the most effective prevention.
Foliage scorch
Late spring frosts can brown new growth. Site in a frost-sheltered position or accept this as cosmetic damage with no long-term harm.
