Eremophila crenulata Plant Care

Eremophila crenulata (Eremophila crenulata) belongs to the Scrophulariaceae family within the Eremophila genus. Eremophila crenulata is native to the far west of Western Australia.

Eremophila crenulata displays a compact, bushy shrub growth habit, reaching up to 4 ft tall with a spread of approximately 4 ft. Eremophila crenulata produces tubular flowers in shades of purple, pink, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Eremophila crenulata 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.

Eremophila crenulata thrives in full sun to partial shade.

Eremophila crenulata tolerates temperatures of 50–90°F. Eremophila crenulata prefers humidity levels of 30–60%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Eremophila crenulata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Eremophila crenulata 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 to partial shade and well-draining sandy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Eremophila crenulata 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.

Eremophila crenulata can spread to about 4 ft (1.2 m) and reach about 4 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Eremophila crenulata 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.

Eremophila crenulata 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.

Eremophila crenulata can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to eremophila plant care, which shares the same genus.

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

Eremophila crenulata grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Eremophila crenulata is native to the far west of Western Australia. In cooler regions, grow Eremophila crenulata as a houseplant or bring it indoors before the first frost.
