Region Sow
Southern England early November to mid February
Midlands early November to mid February
Northern England early November to mid February
Scotland early November to mid February
Southern England - detail & sources

RHS gives no seasonal sowing window (damsons are planted as grafted trees, not sown) -- planted bare-root in the dormant season, roughly November to February. Applied as one UK-wide window across all four sub-regions, matching the convention used for Apple, Pear and Plum.

Growth Stages

Stage BBCH Notes
Planting and establishment 0 Propagate by chip budding or grafting -- seed-grown trees will not match the parent (RHS). Plant in full sun; damson tolerates both exposed and sheltered positions better than plum.
Vegetative growth 3 Slower to reach fruiting maturity than plum -- 10-20 years to full maturity (RHS). Erect, thorny, oval growth habit (NC State Extension).
Blossom and pollination 6 White, cup-shaped blossom in April (NC State Extension). Self-fertile, but crops better with cross-pollination from another variety.
Harvest 8 Harvested August to early September; astringent fruit best used for jam, canning or preserving (NC State Extension).

Harvest & Storage

When to pick: Harvested August to early September (NC State Extension). Small, rounded, blue-black to yellow/red/green fruit with astringent flesh, best suited to jam, canning and preserving rather than eating fresh (RHS; NC State Extension).

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing. How we check our facts.

How this guide is put together

The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against RHS and Met Office guidance. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
