Peace Lily Plant Care

Peace Lily (Spathiphyllum wallisii) belongs to the Araceae family within the Spathiphyllum genus. Peace Lily is native to Colombia, Venezuela. Peace Lily is also known as Spathe Flower.

Peace Lily displays an upright, bushy growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Peace Lily produces white, large spathe, spadix inflorescence.

Leaf size: approximately 12 inches.

Water a young or newly planted Peace Lily every 7–14 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.

Peace Lily thrives in bright indirect light. Avoid placing Peace Lily in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Spathiphyllum wallisii tolerates temperatures of 65–85°F. Peace Lily prefers humidity levels of 40–60%.

Well-draining soil mix. Good drainage is essential for Peace Lily to prevent waterlogging, which leads to root rot and fungal issues.

Feed Peace Lily every month 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and well-draining soil mix. Avoid low spots where water collects after rain.

Peace Lily is suited to USDA Zone 11b – 12b.

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.

Peace Lily can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Peace Lily 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.

Peace Lily is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Peace Lily can be propagated through division or stem cuttings. Similar propagation techniques also apply to floribundum spathiphyllum plant care, which shares the same genus.

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

Peace Lily grows outdoors in USDA Zone 11b – 12b. It survives winters down to planting zone 11b. Peace Lily is native to Colombia, Venezuela. In cooler regions, grow Peace Lily as a houseplant or bring it indoors before the first frost.
