Astragalus iselyi Plant Care

Astragalus iselyi (Astragalus iselyi) belongs to the Fabaceae family within the Astragalus genus. Astragalus iselyi is native to Utah in the United States.

Astragalus iselyi displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 2 ft. Astragalus iselyi produces small pea-like flowers in shades of purple, pink, or white.

Leaf size: approximately 1 inches.

Water a young or newly planted Astragalus iselyi 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.

Astragalus iselyi thrives in full sun to partial shade.

Astragalus iselyi tolerates temperatures of 60–80°F. Astragalus iselyi prefers humidity levels of 40–60%.

Well-draining sandy soil mix with added perlite for extra drainage. Good drainage is essential for Astragalus iselyi to prevent waterlogging, which leads to root rot and fungal issues.

Feed Astragalus iselyi every 8 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 partial shade and well-draining sandy soil mix with added perlite for extra drainage. Avoid low spots where water collects after rain.

Astragalus iselyi 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.

Astragalus iselyi can spread to about 2 ft (0.6 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Astragalus iselyi 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.

Astragalus iselyi 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.

Astragalus iselyi can be propagated through seeds, division of root ball. Similar propagation techniques also apply to aragallus acutirostris plant care, which shares the same genus.

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

Astragalus iselyi grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Astragalus iselyi is native to Utah in the United States. In cooler regions, grow Astragalus iselyi as a houseplant or bring it indoors before the first frost.
