Bay Cedar Plant Care

Bay Cedar (Suriana maritima) belongs to the Surianaceae family within the Suriana genus. Bay Cedar is also known as Sea Lavender, Sea Rosemary.

Bay Cedar displays a low spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Bay Cedar produces small yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Bay Cedar 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.

Bay Cedar thrives in full sun to partial shade.

Suriana maritima tolerates temperatures of 50–90°F. Bay Cedar prefers humidity levels of 40–70%.

Well-draining sandy soil with good organic content. Good drainage is essential for Bay Cedar to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bay Cedar every 6 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.

Choose a spot with full sun to partial shade and well-draining sandy soil with good organic content. Avoid low spots where water collects after rain.

Bay Cedar is suited to USDA Zone 12a.

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.

Bay Cedar can spread to about 3 ft (0.9 m) and reach about 3 ft (1 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 Bay Cedar 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.

Bay Cedar is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Bay Cedar can be propagated through seeds, stem cuttings.

Bay Cedar is susceptible to aphids, scale insects, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Bay Cedar grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Bay Cedar as a houseplant or bring it indoors before the first frost.
