Mediterranean saltwort Plant Care

Mediterranean saltwort (Halocnemum strobilaceum) belongs to the Amaranthaceae family within the Halocnemum genus. Mediterranean saltwort is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East and central Asia.

Mediterranean saltwort displays a low, spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 3 ft. Mediterranean saltwort produces small inconspicuous flowers.

Leaf size: approximately 1 inches.

Water a young or newly planted Mediterranean saltwort every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Mediterranean saltwort thrives in full sun.

Halocnemum strobilaceum tolerates temperatures of 60–90°F. Mediterranean saltwort prefers humidity levels of 40–70%.

Sandy, well-draining soil with high salt tolerance. Good drainage is essential for Mediterranean saltwort to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mediterranean saltwort every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun and sandy, well-draining soil with high salt tolerance. Avoid low spots where water collects after rain.

Mediterranean saltwort is suited to USDA Zone 6a – 11b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Mediterranean saltwort can spread to about 3 ft (0.9 m) and reach about 2 ft (0 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mediterranean saltwort while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Mediterranean saltwort is hardy down to USDA zone 6a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Mediterranean saltwort can be propagated through seeds, stem cuttings.

Mediterranean saltwort is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Mediterranean saltwort grows outdoors in USDA Zone 6a – 11b. It survives winters down to planting zone 6a. Mediterranean saltwort is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East and central Asia.
