California macrophylla Plant Care

California macrophylla (California macrophylla) belongs to the Geraniaceae family within the California genus.

California macrophylla displays a low spreading groundcover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. California macrophylla produces small pink, purple, or white flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted California macrophylla every 7–10 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.

California macrophylla thrives in full sun to partial shade.

California macrophylla tolerates temperatures of 50–80°F. California macrophylla prefers humidity levels of 40–70%.

Well-draining sandy loam with added compost for nutrients. Good drainage is essential for California macrophylla to prevent waterlogging, which leads to root rot and fungal issues.

Feed California macrophylla 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 loam with added compost for nutrients. Avoid low spots where water collects after rain.

California macrophylla 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.

California macrophylla can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune California macrophylla 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.

California macrophylla 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.

California macrophylla can be propagated through seeds, stem cuttings.

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

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