How do you care for Leatherleaf?
Plant Leatherleaf in partial shade to full sun (USDA zones 12a) and water a young shrub every 4–7 days until it is established. It tolerates temperatures of 50–75°F (10–24°C). Fertilize it every 6 months during the growing season.
What Is the Leatherleaf?
Leatherleaf (Chamaedaphne calyculata) belongs to the Ericaceae family within the Chamaedaphne genus. Leatherleaf is also known as Bog Rosemary, Wild Rosemary.
Leatherleaf displays a low, spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Leatherleaf produces small, bell-shaped white or pink flowers in clusters.
Leaf size: approximately 2 inches.
How Often Should You Water a Leatherleaf?
Water a young or newly planted Leatherleaf every 4–7 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

What Soil Mix Works Best for a Leatherleaf?
Moist, acidic, well-draining soil with high organic matter content. Good drainage is essential for Leatherleaf to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Leatherleaf?
Feed Leatherleaf 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 Leatherleaf?
Choose a spot with partial shade to full sun and moist, acidic, well-draining soil with high organic matter content. Avoid low spots where water collects after rain.
Leatherleaf 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 Leatherleaf?
Leatherleaf can spread to about 3 ft (0.9 m) and reach about 3 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 Leatherleaf?
Prune Leatherleaf 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 Leatherleaf in Winter?
Leatherleaf is frost-tender (hardy to USDA zone 12). 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 Leatherleaf?
Leatherleaf can be propagated through seeds, softwood cuttings.
Is the Leatherleaf Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Leatherleaf, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Leatherleaf?
Leatherleaf is susceptible to spider mites, scale insects, aphids. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

What USDA Hardiness Zone Does the Leatherleaf Need?
Leatherleaf grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Leatherleaf as a houseplant or bring it indoors before the first frost.
