Pellitory Plant Care

Pellitory (Parietaria officinalis) belongs to the Urticaceae family within the Parietaria genus. Pellitory is also known as Common Pellitory, Doctor's Pellitory.

Pellitory displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Pellitory produces inconspicuous small greenish flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Pellitory every 7–10 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.

Pellitory thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Pellitory in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Parietaria officinalis tolerates temperatures of 60–75°F. Pellitory prefers humidity levels of 40–60%.

Well-draining soil with high organic content. Good drainage is essential for Pellitory to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pellitory 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.

Choose a spot with partial to full shade and well-draining soil with high organic content. Avoid low spots where water collects after rain.

Pellitory is suited to USDA Zone 13a.

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.

Pellitory 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.

Prune Pellitory 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.

Pellitory is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Pellitory can be propagated through seeds, division of root ball. Similar propagation techniques also apply to pellitory plant care, which shares the same genus.

Pellitory is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Pellitory grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Pellitory as a houseplant or bring it indoors before the first frost.
