Troubleshooting
Spanish Fir problems — and how to fix them
Spanish Fir (Abies pinsapo) 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.
Woolly adelgids
Adelges nordmannianae and related species can colonise needles, causing yellowing and needle drop. Inspect in spring; treat with horticultural oil or systemic insecticide. Good air circulation reduces pressure.
Phytophthora root rot
Waterlogged or poorly drained soils invite Phytophthora cinnamomi, causing dieback from the roots up. Plant on slopes or raised beds; improve drainage before planting rather than trying to treat established infections.
Summer heat scorch
In hot, dry lowland sites, needles brown at the tips in late summer. Site in a position with afternoon shade in USDA zones 8+, and mulch the root zone to retain soil moisture and moderate temperature.
