What Soil Mix Works Best for a Creeping Amaranth?
Well-draining soil with high organic content. Good drainage is essential for Creeping Amaranth to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Creeping Amaranth?
Feed Creeping Amaranth every 4 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 Creeping Amaranth?
Choose a spot with full sun to partial shade and well-draining soil with high organic content. Avoid low spots where water collects after rain.
Creeping Amaranth 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 Creeping Amaranth?
Creeping Amaranth can spread to about 2 ft (0.6 m) and reach about 4 ft (1 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 Creeping Amaranth?
Prune Creeping Amaranth 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 Creeping Amaranth in Winter?
Creeping Amaranth 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 Creeping Amaranth?
Creeping Amaranth can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to southern amaranth plant care, which shares the same genus.
