What is Weeping Forsythia?

Weeping forsythia (Forsythia suspensa) is a deciduous shrub that is beloved for its graceful, arching stems and bright yellow flowers. These plants are part of the Oleaceae family and originate from China. While forsythia species are often upright, weeping forsythia has a more drooping, cascading growth habit that makes it unique and visually appealing.

These shrubs are often used as accent plants or ground cover in the garden due to their spreading nature and ability to form dense mounds of foliage. They can also be trained to grow over fences or walls, adding vertical interest to the garden. The most striking feature, however, is their early spring bloom, when the bare branches are adorned with clusters of golden flowers, signaling the start of the growing season.

Planting Weeping Forsythia

When planting weeping forsythia, location is key. These shrubs thrive in full sun to partial shade, and they prefer well-drained soil with plenty of organic matter. Choose a spot where the shrub has plenty of room to spread out, as weeping forsythia can grow up to 8-10 feet wide.

Step-by-Step Planting Guide:

Choose the Right Location: Select an area with at least 4-6 hours of sunlight daily. Full sun encourages the most abundant flowering, while partial shade is suitable but may reduce flower production slightly.

Prepare the Soil: Loosen the soil to a depth of about 12-18 inches and amend it with compost or well-rotted manure to ensure it’s rich and well-draining. Forsythias tolerate a wide range of soil types but perform best in slightly acidic to neutral pH (6.0-7.0).

Dig the Hole: Make a hole twice as wide and as deep as the root ball. Gently place the shrub in the hole, making sure it’s at the same depth as it was in the container.

Backfill and Water: Fill the hole with soil, tamp it down gently, and water thoroughly to settle the soil around the roots.

Watering and Moisture Needs

Weeping forsythia is relatively drought-tolerant once established, but young plants need consistent moisture to get off to a strong start. After planting, water the shrub deeply once a week for the first growing season, especially during dry spells.

Tips for Watering Weeping Forsythia:

New Plants: Keep the soil consistently moist but not soggy during the first year of growth.

Established Plants: Once established, weeping forsythia can handle periods of drought, but regular watering during dry periods will encourage better blooming.

Mulching: Apply a layer of organic mulch around the base of the plant to help retain soil moisture and regulate soil temperature.

Sunlight Requirements

Weeping forsythia flourishes in full sun, but it can tolerate partial shade. Ideally, plant it where it receives at least 4-6 hours of sunlight daily to ensure the best flower display.

Full Sun vs. Partial Shade:

Full Sun: Ensures maximum flower production and the most vibrant yellow blooms.

Partial Shade: Forsythia can tolerate some shade, but this may lead to fewer flowers and a more open, less dense growth habit.

If you live in a particularly hot climate, providing afternoon shade can protect the plant from intense heat, which might stress the plant, especially during its first few years.

Pruning Weeping Forsythia

Pruning is crucial to keeping your weeping forsythia looking its best and encouraging healthy, vigorous growth. The best time to prune is right after the plant has finished blooming in spring, as forsythia blooms on old wood (the growth from the previous year).

How to Prune Weeping Forsythia:

Remove Dead or Diseased Wood: Start by cutting out any dead, diseased, or damaged branches.

Shape the Plant: Trim the shrub to control its size and shape. You can cut back the longest, arching stems to promote a more compact form.

Encourage New Growth: Remove older branches near the base to encourage new shoots and maintain the plant’s youthful, blooming vigor.

Regular pruning keeps your weeping forsythia from becoming too leggy or overgrown and ensures that it remains dense and productive year after year.

Fertilizing for Optimal Growth

Weeping forsythia doesn’t require heavy feeding, but applying a balanced, slow-release fertilizer in early spring can give the shrub a boost and promote healthy growth.

Fertilizer Application:

When to Fertilize: Apply a balanced 10-10-10 fertilizer in early spring, just before new growth begins.

How to Apply: Scatter the fertilizer around the base of the plant, keeping it away from direct contact with the stems. Water the area thoroughly to help the nutrients reach the roots.

For an organic approach, you can top-dress the soil with compost in spring, which provides slow-release nutrients throughout the growing season.

Common Pests and Diseases

Weeping forsythia is relatively pest-resistant, but it’s still important to be aware of potential problems. Common pests include aphids and scale insects, which can be treated with insecticidal soap or neem oil.

Pest and Disease Management:

Aphids: Look for small clusters of these soft-bodied insects on new growth. Use a strong spray of water or insecticidal soap to control infestations.

Scale Insects: These tiny, hard-shelled pests attach to stems and leaves. Use neem oil or a horticultural oil spray to keep them under control.

Leaf Spot: If you notice dark spots on the leaves, this fungal disease can be managed by improving air circulation around the plant and avoiding overhead watering.

Regularly inspecting your plants for signs of stress can help catch and treat issues before they become serious.

Propagating Weeping Forsythia

Want more weeping forsythia in your garden or to share with friends? The good news is that these shrubs are easy to propagate through cuttings or layering.

Propagation Methods:

Cuttings: In summer, take a 6-inch softwood cutting from new growth, dip the cut end in rooting hormone, and plant it in a pot with moist, well-draining soil. Keep the cutting moist and in indirect light until it establishes roots.

Layering: Choose a low-hanging branch, bury a section of it in the soil (while it’s still attached to the main plant), and wait for roots to form. Once rooted, cut the branch from the parent plant and transplant it to a new location.

Both methods are effective, but layering tends to have a higher success rate.
