What Soil Mix Works Best for a Blue-eyed Mary?
Moist, well-draining soil with high organic content. Good drainage is essential for Blue-eyed Mary to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Blue-eyed Mary?
Feed Blue-eyed Mary 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 Blue-eyed Mary?

Blue-eyed Mary is suited to USDA Zone 12a.
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 Blue-eyed Mary?
Blue-eyed Mary 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.

How Do You Prune a Blue-eyed Mary?
Prune Blue-eyed Mary while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

Blue-eyed Mary can be propagated through division, seeds. Similar propagation techniques also apply to cappadocian navelwort plant care, which shares the same genus.
