Yellow Hawkweed Plant Care

Yellow Hawkweed (Pilosella floribunda) belongs to the Asteraceae family within the Pilosella genus. Yellow Hawkweed is native to United States and Canada. Yellow Hawkweed is also known as Woodland Hawkweed, Hieracium ambiguum, Hieracium apatorium.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Yellow Hawkweed 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.

Yellow Hawkweed thrives in full sun to part shade.

Pilosella floribunda tolerates temperatures of 50–75°F. Yellow Hawkweed prefers humidity levels of 40–70%.

Well-draining sandy soil mix with some organic matter. Good drainage is essential for Yellow Hawkweed to prevent waterlogging, which leads to root rot and fungal issues.

Feed Yellow Hawkweed 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to part shade and well-draining sandy soil mix with some organic matter. Avoid low spots where water collects after rain.

Yellow Hawkweed 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.

Yellow Hawkweed 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 Yellow Hawkweed 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.

Yellow Hawkweed 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.

Yellow Hawkweed can be propagated through seeds, division of offsets. Similar propagation techniques also apply to chlorocrepis albiflora plant care, which shares the same genus.

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

Yellow Hawkweed grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Yellow Hawkweed is native to United States and Canada. In cooler regions, grow Yellow Hawkweed as a houseplant or bring it indoors before the first frost.
