How to Grow Purslanes 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.
In the UK, purslanes go in the ground early May to early July.
Purslanes (Portulaca oleracea) — annual.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early May in Southern England to early May in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
Johnny's Selected Seeds: direct-sow well after the last frost once soil is reliably warm; a single window is applied uniformly across all four sub-regions since the source gives no UK-region-specific gradient, and monthly successional sowing through the warm season is recommended regardless of region.

Direct-sow fresh seed about 0.5cm deep in full sun, well after the last frost once soil is reliably warm; germinates in 7-10 days (Johnny's Selected Seeds).
Thinning and establishment
1
Thin seedlings to 10-15cm apart; water regularly until well established, in lean, well-drained soil (Johnny's Selected Seeds).
Succulent leafy growth
3
Becomes notably drought-tolerant once established, needing only deep, infrequent watering; loves baking full sun and lean soil (Johnny's Selected Seeds).
Continuous harvest
8
Harvest young, tender stems and leaves continuously from about 4-6 weeks after germination, through to 40-60 days maturity; monthly successional sowing keeps up supply (Johnny's Selected Seeds).
Directly fetched and verified. RHS explicitly does not recommend pesticide use against aphids; recommends tolerance, manual squashing, and encouraging/purchasing natural predators (ladybirds, hoverflies, lacewings, parasitoid wasps, earwigs) as biological control, especially under glass.
Directly fetched and verified (canonical URL differs from requested URL /biodiversity/slugs -> redirects to /biodiversity/slugs-and-snails). RHS explicitly advises against slug pellets (even organic) due to wildlife harm, and cites RHS's own controlled trial finding no damage reduction from physical barriers (copper tape, bark mulch, eggshell, grit, wool) -- while also noting some other studies have shown copper barriers to repel slugs, a preserved disagreement rather than a silently resolved one. Details Nemaslug (Phasmarhabditis hermaphrodita) biological control including application temperature range and its lack of effect on snails specifically.
5 independent sources are cited for this crop. Where they disagree - soil pH is the clearest case - every figure is preserved rather than averaged into false precision.
Frequently Asked Questions
When should I sow purslanes in the UK?
In Southern England, from early May. In Scotland, wait until early May. 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 purslanes?
Sow early May to early July.
What problems affect purslanes?
Our data links 1 disease and 4 pests to this crop. See the sections above for each one and how to manage it.
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.
