Weeping Forsythia Plant Care

Weeping Forsythia (Forsythia suspensa) belongs to the Oleaceae family within the Forsythia genus. Weeping Forsythia is native to China. Weeping Forsythia is also known as Drooping Forsythia.

Weeping Forsythia displays an upright, arching shrub growth habit, reaching up to 8 ft tall with a spread of approximately 10 ft. Weeping Forsythia produces bright yellow, bell-shaped flowers in early spring.

Leaf size: approximately 3 inches.

Water a young or newly planted Weeping Forsythia every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Weeping Forsythia thrives in full sun to partial shade.

Forsythia suspensa tolerates temperatures of 0–90°F. Weeping Forsythia prefers humidity levels of 40–70%.

Well-draining, fertile soil with a mix of compost and sand. Good drainage is essential for Weeping Forsythia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Weeping Forsythia every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 full sun to partial shade and well-draining, fertile soil with a mix of compost and sand. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Weeping Forsythia can spread to about 10 ft (3 m) and reach about 8 ft (2 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Weeping Forsythia 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 tree in one year.

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 trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Weeping Forsythia can be propagated through softwood cuttings, hardwood cuttings. Similar propagation techniques also apply to greenstem forsythia plant care, which shares the same genus.

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