How to Care for Purslane

Purslane (Portulaca oleracea) is a low, spreading succulent with fleshy paddle-shaped leaves and reddish trailing stems. It is one of the most heat- and drought-tolerant ornamentals you can grow, ideal for baking spots where little else thrives.

Light

Give purslane full sun, the more the better. It craves heat and bright light, which keep growth compact and encourage its small cup-shaped flowers to open. In shade the plant grows leggy, blooms poorly, and its flowers may stay closed. A minimum of 6 to 8 hours of direct sun is ideal.

Water

Purslane is highly drought-tolerant thanks to its water-storing leaves. Water sparingly and let the soil dry well between waterings. Overwatering is the main way to kill it, causing stem and root rot. Established plants often survive on rainfall alone; container plants need only occasional deep watering during extended dry heat.

Soil & Potting

Plant in poor to average, sharply draining soil; purslane actually prefers lean conditions and dislikes rich, moisture-retentive mixes. Sandy or gravelly soil is perfect. In containers use a cactus or succulent mix, or amend potting soil with plenty of grit and sand, and always use pots with drainage holes.

Humidity & Temperature

This is a warm-climate plant that loves heat and shrugs off dry air. It thrives in the heat of summer and is sensitive to cold, collapsing at the first frost. Treat it as a warm-season annual outside frost-free regions. Low humidity suits it perfectly.

Feeding

Purslane needs little to no fertilizer and performs beautifully in lean soil. If growth is very sparse, a light dose of dilute balanced fertilizer early in the season is plenty. Overfeeding produces soft, floppy growth and fewer flowers.

Propagation

Purslane propagates with ease. Stem cuttings root readily; simply lay or press a piece of stem into moist soil and it will take. It also grows quickly from seed sown on the soil surface in warm conditions, and it self-sows freely, sometimes to the point of spreading.

Repotting / Pruning

Pinch or trim trailing stems to keep plants tidy and encourage branching in containers and baskets. Purslane rarely needs repotting given its fast, annual nature. Remove any mushy or rotted stems promptly. Cutting back leggy growth in midsummer rejuvenates the plant.

Common Problems & Pests

The most common issue is rot from overwatering or heavy soil, so err on the dry side. Aphids and occasionally slugs or snails may nibble tender growth. Poor flowering almost always traces to insufficient sun. Otherwise this is a remarkably trouble-free plant.

Seasonal Care Tips

Plant or sow after all danger of frost when soil is warm. Purslane peaks in the hottest part of summer with minimal care. As nights cool in fall, growth slows and frost ends the season; collect self-sown seedlings or take cuttings to overwinter indoors on a sunny sill in cold climates.
