Troubleshooting
Packham pear problems — and how to fix them
Packham pear (Pyrus communis 'Packham's Triumph') 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.
Requires two diploid pollinators
Packham's Triumph is a triploid and produces non-viable pollen. Two compatible diploid cultivars (e.g. 'Conference' and 'Beurré Hardy') must be planted nearby and flower simultaneously to ensure adequate fruit set.
Pear scab (Venturia pirina)
Moderately susceptible in wet climates. Scabby lesions reduce fruit quality. Apply copper fungicide from green cluster to petal fall in high-pressure years, maintain open canopy, and remove infected fallen leaves.
Late ripening in cool climates
In the UK, Packham's Triumph can struggle to ripen fully in cool, cloudy summers. Harvest in late October and store in a cool room (2–4°C) to complete ripening over 4–6 weeks. Warm south-facing walls significantly improve results.
