Warty Gel Plant Care

Warty Gel (Geleznowia verrucosa) belongs to the Rutaceae family within the Geleznowia genus. Warty Gel is native to Western Australia. Warty Gel is also known as Yellow Bells.

Warty Gel displays a compact, rounded shrub growth habit, reaching up to 3 ft tall with a spread of approximately 3 ft. Warty Gel produces small white or pink flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Warty Gel 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.

Warty Gel thrives in full sun to partial shade.

Geleznowia verrucosa tolerates temperatures of 50–85°F. Warty Gel prefers humidity levels of 40–70%.

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

Feed Warty Gel 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.

Warty Gel 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.

Warty Gel 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 Warty Gel 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.

Warty Gel 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.

Warty Gel can be propagated through seeds, semi-hardwood cuttings.

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

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