Plan your Purslanes planting
When to sow and plant Purslanes depends on your own frost dates. Check the UK vegetable planting calendar. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.
What the research guides add
Purslane is a garden weed and a salad plant at once, and NC State describes its toughness.
- An annual succulent that is drought-tolerant once established and grows in full sun and well-drained soil; propagation is by seed and stem cuttings. (NC State Extension)
- Its taproot and fibrous secondary roots tolerate poor, compacted soils and drought. (NC State Extension)
- The flowers are small, yellow and open only briefly in the morning, each replaced by a seed capsule that splits to release dark seeds. (NC State Extension)

Direct-sow fresh seed in full sun after last spring frost, in well-drained, lean soil, pH 5.5-7.0, seeds 1/4in (0.5cm) deep. Sow well after the last frost once soil is reliably warm; germinates in 7-10 days. Thin to 10-15cm apart. Loves baking sun and lean soil; water deeply but infrequently once established, drought-tolerant thereafter, but water regularly until established. Matures in just 40-60 days; harvest young, tender stems and leaves continuously from 4-6 weeks after germination, picking sprigs throughout the season. Monthly successional sowing gives a continuous supply.

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.
-
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.

Frequently Asked Questions
When should I sow purslane in the UK?

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.

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.
