Red Mistletoe Plant Care

Red Mistletoe (Viscum cruciatum) belongs to the Santalaceae family within the Viscum genus. Red Mistletoe is native to Lebanon, Morocco, Israel, Palestine, Portugal, Spain, and Syria.

Red Mistletoe displays a parasitic shrub growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Red Mistletoe produces small inconspicuous flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Red Mistletoe 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.

Red Mistletoe thrives in partial to full shade. The optimal light range is 50–200 lux. Avoid placing Red Mistletoe in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Viscum cruciatum tolerates temperatures of 60–75°F. Red Mistletoe prefers humidity levels of 40–70%.

Well-draining sandy loam with organic matter. Good drainage is essential for Red Mistletoe to prevent waterlogging, which leads to root rot and fungal issues.

Feed Red Mistletoe 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 partial to full shade and well-draining sandy loam with organic matter. Avoid low spots where water collects after rain.

Red Mistletoe is suited to USDA Zone 8b – 10b.

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.

Red Mistletoe can spread to about 2 ft (0.6 m) and reach about 2 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 Red Mistletoe 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.

Red Mistletoe is hardy down to USDA zone 8b, so once established it can stay outdoors through winter in that zone and warmer ones.

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.

Red Mistletoe can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to european mistletoe plant care, which shares the same genus.

Red Mistletoe is susceptible to aphids, scale insects, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
