Bulbous Hawkbit Plant Care

Bulbous Hawkbit (Leontodon bulbosus) belongs to the Asteraceae family within the Leontodon genus. Bulbous Hawkbit is native to the Mediterranean basin countries of southern Europe, Western Asia, and North Africa, as well as the Azores (Terceira) and Ireland. Bulbous Hawkbit is also known as Leontodon bulbosus, Aetheorhiza bulbosa, Crepis bulbosa.

Bulbous Hawkbit displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Bulbous Hawkbit produces small yellow daisy-like flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Bulbous Hawkbit 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.

Bulbous Hawkbit thrives in full sun to partial shade.

Leontodon bulbosus tolerates temperatures of 50–75°F. Bulbous Hawkbit prefers humidity levels of 40–60%.

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

Feed Bulbous Hawkbit 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. Avoid low spots where water collects after rain.

Bulbous Hawkbit is suited to USDA Zone 8a – 10b.

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.

Bulbous Hawkbit can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Bulbous Hawkbit 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.

Bulbous Hawkbit is hardy down to USDA zone 8a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Bulbous Hawkbit can be propagated through seeds, division of clumps. Similar propagation techniques also apply to hairy hawkbit plant care, which shares the same genus.

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

Bulbous Hawkbit grows outdoors in USDA Zone 8a – 10b. It survives winters down to planting zone 8a. Bulbous Hawkbit is native to the Mediterranean basin countries of southern Europe, Western Asia, and North Africa, as well as the Azores (Terceira) and Ireland.
