Plant Needs
Sunlight
Partial to full sun; tolerates light shade, requires at least 4 hours of direct or filtered sunlight daily to maintain dense growth.
Watering
Keep soil evenly moist but not waterlogged; avoid allowing the soil to dry out completely during hot, dry periods.
Temperature
Hardy to -15°C; thrives in cool temperate conditions, avoid prolonged exposure to temperatures above 28°C.
Characteristics
- Leaf: Tiny, opposite, oval to lanceolate, bright green, moss-like foliage.
- Flower: Small white 5-petaled star-shaped blooms held just above the foliage.
- Stem: Slender, creeping stems that root at nodes to form continuous dense mats.
Care Guide
Watering
Keep soil consistently moist, water when the top 1 cm of soil feels dry
Fertilization
Diluted balanced liquid feed once every 6 weeks. Use a low-strength fertilizer to avoid encouraging leggy growth that disrupts the mat form.
Eggshell powder topdressing：Crush clean, dried eggshells into fine powder and sprinkle a thin layer on the soil surface to boost calcium levels and improve drainage; avoid overapplication to prevent pH imbalance.Pruning
- Trim back straggly or overgrown stems in early spring to maintain a tight, dense mat form.
- Remove spent flower heads promptly to keep the planting tidy and redirect energy to foliage growth.
- Thin overcrowded patches to improve airflow and reduce the risk of fungal disease in damp conditions.
