How to Grow Winter Purslane (Miner's Lettuce) UK | Regional Planting Calendar
Move through the SoilCommander growing library like a course: keep the navigation in place, open the next lesson, and build your garden plan step by step.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early September in Southern England to early September in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
Plantura/GrowVeg: sow September through to March, while temperatures remain below 12C, because the seed needs a cold stimulus to germinate -- this window deliberately runs across the turn of the year (start DOY 244 in early September, end DOY 90 at the end of March). A single window is applied uniformly across all four sub-regions since the sources give no UK-region-specific gradient; this is a hardy cold-season crop grown through the winter everywhere in the UK, and the sources recommend cloche or cold-greenhouse protection for reliable winter cropping regardless of region.

Sow September to March while temperatures stay below 12C (ideally 8-12C), since the seed needs a cold stimulus; sow about 1cm deep and 5cm apart in rows 10-15cm apart. Germination takes two to three weeks (Plantura).
Thinning and establishment
1
Thin direct-sown plants to about 10cm apart, or plant out from modules at the same spacing, into loose, humus-rich sandy soil in sun or semi-shade (GrowVeg, Plantura).
Rosette growth
3
Plants form a rosette of succulent basal leaves reaching about 30cm; they tolerate mild frost outdoors but crop far more reliably under a cloche or in a cold greenhouse (Plantura, GrowVeg).
Cut-and-come-again harvest and self-seeding
4
Harvest from six to eight weeks after sowing, cutting mature leaves at least 2cm above ground with a sharp knife so plants regrow, from October through to April. Flowering shoots carry the distinctive fused disc-shaped leaf; deadhead unless self-seeding is wanted (Plantura, GrowVeg).
When to pick: Sow late summer for autumn-to-early-winter harvest, or spring for a summer crop. Cut-and-come-again -- both leaves and flowering shoots are edible.
Winter Purslane, the Salad Leaf That Crops Through Winter
Originates in the western mountainous and coastal regions of North America, now established throughout the UK. Annual reaching about 30cm, forming succulent basal leaves in a rosette; younger paired leaves fuse into a disc below the flower head, the defining feature of the species. Hardy, and the succulent leaves let it survive brief dry periods. Seed needs a cold stimulus and is sown September to March while temperatures stay below 12C, ideally 8-12C. Sow about 5cm apart at 1cm deep with rows 10-15cm apart. Wants nutrient-rich, loose, humus-rich sandy earth and a semi-shady site; does not tolerate salt. Ready to harvest 6-8 weeks after sowing; cut mature leaves at least 2cm from the ground with a sharp knife, between October and April. Self-pollinates and self-seeds annually -- deadhead to prevent uncontrolled spread.

Frequently Asked Questions
When should I sow winter purslane (miner's lettuce) in the UK?
In Southern England, from early September. In Scotland, wait until early September. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.
When do I sow winter purslane (miner's lettuce)?
Sow early September to late March.
Plan next season before the problems start
Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.
