What Soil Mix Works Best for a Pink Ammannia?
Rich, loamy soil with good drainage. Good drainage is essential for Pink Ammannia to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Pink Ammannia?
Feed Pink Ammannia 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.

Where Should You Plant a Pink Ammannia?
Choose a spot with full sun to partial shade and rich, loamy soil with good drainage. Avoid low spots where water collects after rain.
Pink Ammannia is suited to USDA Zone 13b.
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 Pink Ammannia?
Pink Ammannia can spread to about 3 ft (0.9 m) and reach about 2 ft (1 m) tall. Space plants about 3 ft (0.9 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 Pink Ammannia?
Prune Pink Ammannia while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
