What Is the Seablite?
Seablite (Sesuvium acutifolium) belongs to the Aizoaceae family within the Sesuvium genus. Seablite is native to Africa, Asia, Australia, Hawai`i, North America and South America, and has naturalised in many places. Seablite is also known as Sea Purslane.
Seablite displays a low-growing, spreading succulent growth habit, reaching up to tall with a spread of approximately 1 ft. Seablite produces small, colorful flowers in shades of pink, purple, or white.
Leaf size: approximately 2 inches.
How Often Should You Water a Seablite?
Sesuvium acutifolium requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

What Soil Mix Works Best for a Seablite?
Sandy, well-draining soil mix with added perlite and coarse sand. Good drainage is essential for Seablite to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Seablite?
Feed Seablite every 2 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.
Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
Fertilizing
Every 2 months
During the growing season
The PlantoScan app can remind you when to water and when to fertilize each plant.
How Do You Repot a Seablite?
Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Seablite?
Seablite can be propagated through propagation by seeds or stem cuttings. Similar propagation techniques also apply to sea purslane plant care, which shares the same genus.
Is the Seablite Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Seablite, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.
