Troubleshooting
Foxtail Pine problems — and how to fix them
Foxtail Pine (Pinus balfouriana) 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.
Root rot in wet soil
The single most common killer in gardens. Plant on a slope or raised, gritty bed and never let it sit in waterlogged ground.
Heat and humidity stress
A subalpine species that struggles in hot, muggy lowland summers; site it where air moves freely and afternoon heat is moderated.
White pine blister rust
As a five-needle white pine it is susceptible to this fungal disease; keep alternate hosts (currants, gooseberries) away and remove cankered branches.
Transplant shock
Slow to re-establish after moving. Plant small, young specimens and disturb the roots as little as possible.
