What Soil Mix Works Best for a Southern Sea Heath?
Sandy, well-draining soil with low fertility. Good drainage is essential for Southern Sea Heath to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Southern Sea Heath?
Choose a spot with full sun and sandy, well-draining soil with low fertility. Avoid low spots where water collects after rain.
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 Do You Prune a Southern Sea Heath?
Prune Southern Sea Heath 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 Southern Sea Heath in Winter?
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.
