Common purslane problems — and how to fix them
Common purslane (Portulaca oleracea) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bolting (premature flowering)
Purslane bolts quickly in drought stress or very long days — harvest leaves regularly, keep soil reasonably moist and make successive small sowings every 3 weeks to maintain tender growth throughout the season.
Powdery mildew in humid conditions
Crowded plants in still, humid air can develop powdery mildew — space plants 15-20 cm apart, improve airflow and avoid overhead watering in the evening.
Slugs and snails on seedlings
Young seedlings are vulnerable to slug damage — use copper tape around containers, apply organic slug pellets or set beer traps; direct sowing in warm, dry soil reduces susceptibility.
Prevent common purslane problems before they start
Most common purslane issues are care-mismatch, not bad luck. Dial in the basics:
