Troubleshooting
Wild Service Tree problems — and how to fix them
Wild Service Tree (Sorbus torminalis) 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.
Slow, sparse natural regeneration
Seed germinates poorly and seedlings are slow, so it spreads mainly by root suckers. Propagate deliberately rather than relying on self-seeding.
Fireblight
Blackened, wilting blossom and shoots from a Rosaceae bacterial infection. Remove affected wood well below the damage and disinfect tools between cuts.
Bitter raw fruit
Chequers are hard, gritty and astringent until bletted by frost or indoor storage, after which they sweeten markedly. Never use them raw.
Browsing damage
Young trees and suckers are vulnerable to deer and rabbit browsing. Protect with tree guards or fencing in rural and woodland plantings.
