Guilfoylia monostylis Plant Care

Guilfoylia monostylis (Guilfoylia monostylis) belongs to the Surianaceae family within the Guilfoylia genus.

Guilfoylia monostylis displays a compact, spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Guilfoylia monostylis produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Guilfoylia monostylis 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.

Guilfoylia monostylis thrives in full sun to partial shade.

Guilfoylia monostylis tolerates temperatures of 60–80°F. Guilfoylia monostylis prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Guilfoylia monostylis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Guilfoylia monostylis 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 organic matter for moisture retention. Avoid low spots where water collects after rain.

Guilfoylia monostylis is suited to USDA Zone 13a.

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.

Guilfoylia monostylis 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 Guilfoylia monostylis 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.

Guilfoylia monostylis is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Guilfoylia monostylis can be propagated through seeds, stem cuttings.

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

Guilfoylia monostylis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Guilfoylia monostylis as a houseplant or bring it indoors before the first frost.
