How to Sow Super Green Purslane Seeds 

Super green purslane is a compact, lush green plant, popular for its use in salads, side garnishes, and various dishes. This half-hardy annual grows to a maximum height of 40cm and is known for its spreading habit, thriving well in UK climates. Although sometimes considered a weed, purslane is valued for its nutritional content and easy growth. When harvested selectively, each plant can produce multiple crops throughout the growing season. If left to mature, purslane will self-seed, potentially spreading in the surrounding area. 

When and Where to Sow Super Green Purslane Seeds 

• Outdoor Sowing: For best results, sow purslane seeds outdoors during the height of summer when the weather is warmest. This ensures the highest germination rates in outdoor conditions.
• Indoor Sowing: If you wish to start early or sow indoors, use a heated propagator or place pots in a sunny spot to maintain a minimum temperature of 20°C. Purslane will germinate at lower temperatures, but warmth helps accelerate the process. 

Ideal Growing Conditions for Purslane 

• Soil Requirements: Purslane grows well in well-drained soil. If planting outdoors, ensure the soil is free-draining and avoid overwatering, as excess moisture can hinder growth. 
• Sunlight: Purslane thrives in full sun, so place pots or seed trays in a sunny location, whether indoors or outdoors. 
• Temperature: While adult purslane plants can tolerate cooler temperatures, keeping the soil warm at around 20°C will promote faster germination and healthier growth. 

How to Sow Super Green Purslane Seeds Indoors 

1. Sowing Depth and Spacing: Sow seeds around 1/2 inch deep in pots or seed trays filled with high-quality compost. Ensure the compost is lightly pressed, and space seeds thinly to allow room for growth. 
2. Watering: Keep the soil or compost moist but not waterlogged. Purslane prefers moderate watering, especially during the germination phase. 
3. Germination Period: Purslane seeds typically germinate within 10-15 days under ideal conditions. Once seedlings have grown large enough to handle, they can be transplanted to their final growing location. 
4. Transplanting: After seedlings reach a height of around 5-6cm, transplant them into larger pots, containers, or directly into the garden. Space plants about 20-30cm apart to allow them to spread. 

How to Sow Super Green Purslane Seeds Outdoors 

1. Sowing Directly Outdoors: Wait until late spring or early summer when the weather is consistently warm, and there’s no risk of frost. Purslane will germinate well in warm soil and will thrive once established. 
2. Sowing Depth: Sow seeds 1/2 inch deep into the soil, ensuring even distribution for good coverage. Keep the area free-draining and avoid overwatering. 
3. Watering and Sunlight: Ensure the plants receive full sunlight and water regularly but avoid saturating the soil. Purslane is drought-tolerant once established but benefits from occasional watering during dry periods. 
4. Harvesting: Leaves can be harvested a few weeks after the plant reaches maturity or allowed to grow for larger leaves. Purslane is a prolific crop, so harvesting regularly will encourage continuous growth. 

Caring for Super Green Purslane Plants 

• Watering: Once established, purslane is drought-tolerant, but it will benefit from consistent moisture during the early stages of growth. Avoid overwatering, as purslane prefers well-drained soil. 
• Pruning and Harvesting: Selectively harvest the leaves as needed for a continuous supply. Leaving the plant to grow longer will result in a larger crop. Prune back as necessary to prevent excessive spreading or reseeding. 
• Self-Seeding: Purslane is a self-seeding plant, meaning it can spread naturally if left to mature. To control growth, cut back the plants before they set seed, especially if you want to avoid excessive spreading. 

Common Questions About Growing Super Green Purslane 

• Can purslane grow in cooler climates? Yes, while purslane prefers warmer conditions for germination, the adult plants are hardy and can tolerate cooler temperatures, making them suitable for growing in the UK. 

• Is purslane invasive? Purslane can spread quickly if left to self-seed. If you want to control its spread, make sure to harvest or prune the plant before it flowers and sets seed. 

• How long does it take for purslane to grow? Purslane is a fast-growing plant, typically ready to harvest a few weeks after germination. It can provide multiple harvests if leaves are picked selectively. 

• Can purslane be grown indoors? Yes, purslane grows well indoors in pots or containers. Just ensure it receives plenty of sunlight and keep the soil moist during the germination period. 

• What are the best conditions for purslane germination? Purslane seeds germinate best at temperatures around 20°C in a sunny and warm location. While it can tolerate slightly lower temperatures, warmth will promote quicker germination. 

By following these steps, you can successfully grow super green purslane, whether indoors or outdoors, ensuring a constant supply of fresh leaves for your salads, dishes, and garnishes.
