What Soil Mix Works Best for a Deseret Milkvetch?

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

How Often Should You Fertilize a Deseret Milkvetch?

Feed Deseret Milkvetch 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.

Where Should You Plant a Deseret Milkvetch?

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.

Deseret Milkvetch 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.

How Far Apart Should You Plant a Deseret Milkvetch?

Deseret Milkvetch 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.

How Do You Prune a Deseret Milkvetch?

Prune Deseret Milkvetch 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.

How Do You Care for a Deseret Milkvetch in Winter?

Deseret Milkvetch 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.

How Do You Propagate a Deseret Milkvetch?

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