Bronchial Saxifrage Plant Care

Bronchial Saxifrage (Saxifraga bronchialis) belongs to the Saxifragaceae family within the Saxifraga genus. Bronchial Saxifrage is native to northern Asia and North America. Bronchial Saxifrage is also known as Alpine Saxifrage.

Bronchial Saxifrage displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Bronchial Saxifrage produces small, star-shaped flowers in various colors.

Leaf size: approximately 2 inches.

Water a young or newly planted Bronchial Saxifrage 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.

Bronchial Saxifrage thrives in bright indirect light. Avoid placing Bronchial Saxifrage in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Saxifraga bronchialis tolerates temperatures of 50–75°F. Bronchial Saxifrage prefers humidity levels of 40–60%.

Well-draining soil mix with high organic content. Good drainage is essential for Bronchial Saxifrage to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bronchial Saxifrage 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 bright indirect light and well-draining soil mix with high organic content. Avoid low spots where water collects after rain.

Bronchial Saxifrage is suited to USDA Zone 2a – 6b.

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.

Bronchial Saxifrage 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 Bronchial Saxifrage 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.

Bronchial Saxifrage is hardy down to USDA zone 2a, 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.

Bronchial Saxifrage can be propagated through division, seed sowing. Similar propagation techniques also apply to arctic saxifrage plant care, which shares the same genus.

Bronchial Saxifrage 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.

Bronchial Saxifrage grows outdoors in USDA Zone 2a – 6b. It survives winters down to planting zone 2a. Bronchial Saxifrage is native to northern Asia and North America.
