What Soil Mix Works Best for a Pacific Labrador Tea?

Moist, acidic, well-draining soil with high organic matter content. Good drainage is essential for Pacific Labrador Tea to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Pacific Labrador Tea?

Feed Pacific Labrador Tea 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 Pacific Labrador Tea?

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.

Pacific Labrador Tea 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 Pacific Labrador Tea?

Pacific Labrador Tea can spread to about 3 ft (0.9 m) and reach about 4 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 Pacific Labrador Tea?

Prune Pacific Labrador Tea 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.
