Alkali seaheath (Frankenia salina) is a fairly rare, low-growing, woody bush found near beaches, estuaries, and salt marshes. It has adapted to living in salty habitats by being able to excrete salt through specialized glands. The sun dries the liquid and leaves crystals of salt on the leaves. This is a useful groundcover for saline soils.

Water:
Alkali seaheath is well-suited for saline coastal environments, thriving with minimal moisture. It requires watering once weekly and flourishes in well-draining soil, enhancing drought resistance and reducing root rot risk. Its remarkable drought tolerance reflects adaptability to arid conditions.
Fertilize:
Optimal fertilization of alkali seaheath requires balanced-nutrient formulas during spring-summer growth. Monthly applications, as directed, boost vitality. Reduce feeding in winter dormancy. Avoid over-fertilization to protect alkali seaheath's salt tolerance, incorporating gently into soil to prevent root burn and ensure plant health.
Pruning:
Alkali seaheath is a salt-tolerant perennial found in coastal regions. Prune in early to late spring to remove dead stems and thin crowded areas for better air circulation. Regular pruning enhances its compact form and resilience. Use clean, sharp tools for effective maintenance.
Propagation:
To propagate alkali seaheath, use healthy, non-flowering cuttings in a well-draining medium that mimics its native coastal habitat. Keep the substrate moist but not waterlogged. Once rooted, acclimatize young plants gradually to outdoor conditions before transplanting to their permanent location.
