How to Grow Winter Jasmine (Jasminum nudiflorum)

Winter jasmine (Jasminum nudiflorum) is a vigorous, deciduous climber that brings cheer to the garden in the bleak winter months with its bright yellow blooms. Native to China, this tough and reliable plant is ideal for UK gardens, offering a burst of colour from November to February. Here’s how to cultivate and care for winter jasmine.

Key Characteristics

• Type: Deciduous climber or trailing shrub.
• Height and Spread: Up to 3m (10ft) high and wide if trained, but can be kept smaller.
• Flowers: Small, bright yellow, star-shaped blooms on bare stems from November to February.
• Foliage: Green, trifoliate leaves appear after flowering in early spring.
• Hardiness: Fully hardy (H6), tolerating temperatures down to -15°C.

Where to Plant Winter Jasmine

Winter jasmine thrives in various conditions, making it a versatile choice for UK gardens.

Position

• Prefers full sun or partial shade. Full sun encourages the best flowering.
• Ideal for training against walls or fences, particularly south- or west-facing ones.

Soil

• Grows well in most well-drained soils, including chalk, clay, loam, and sandy types.
• Prefers slightly alkaline to neutral pH levels but is adaptable.

Planting Winter Jasmine

1. Timing: Plant in autumn or spring when the soil is warm and workable.
2. Preparation:

• Choose a site with well-drained soil.
• Improve heavy clay with compost or grit to enhance drainage.

1. Planting:

• Dig a hole twice as wide as the root ball.
• Place the plant at the same depth it was in its pot, backfill with soil, and firm down.
• Water thoroughly after planting.

How to Train Winter Jasmine

Winter jasmine isn’t a self-clinging climber and requires support.

• Against Walls or Fences: Use horizontal wires, trellis, or hooks to secure stems. Tie shoots loosely to supports as they grow.
• As Ground Cover: Allow the stems to trail naturally over banks or low walls.

Care and Maintenance

Watering

• Established plants rarely need watering unless conditions are exceptionally dry.
• Water new plants regularly during their first growing season.

Feeding

• Apply a balanced fertilizer in early spring after flowering to encourage healthy growth and blooms.
• Mulch annually with well-rotted compost or manure to improve soil fertility.

Pruning

• Prune immediately after flowering (late winter to early spring).
• Cut back one-third of the oldest stems to the base to encourage new growth.
• Trim long, unruly shoots to maintain the desired shape and size.

Pests and Diseases

Winter jasmine is generally pest-free and disease-resistant. However, watch for:

• Aphids: May occasionally infest new growth. Treat with insecticidal soap or encourage natural predators like ladybirds.
• Root Rot: Avoid overwatering, especially in poorly drained soils, to prevent root rot.

Companion Planting

Pair winter jasmine with other winter-interest plants to create a vibrant seasonal display:

• Snowdrops (Galanthus): For a delicate white contrast beneath the cascading yellow blooms.
• Hellebores (Helleborus): Their bold flowers provide texture and colour variety.
• Dogwood (Cornus): Bright red or yellow stems add structure and complement winter jasmine’s flowers.

Propagation

Winter jasmine is easy to propagate, making it an excellent plant to share with friends or expand in your garden.

By Layering

1. Bend a low-growing stem to the ground in spring.
2. Cover a section with soil, leaving the tip exposed.
3. Secure with a stone or garden peg.
4. Roots will develop within a year, and the new plant can be separated.

By Cuttings

1. Take 10–15cm (4–6in) semi-ripe cuttings in summer.
2. Remove the lower leaves and insert into a pot of moist, gritty compost.
3. Keep in a sheltered spot until rooted, then pot up or plant out.

Seasonal Care Tips

• Autumn: Plant new specimens or prepare older plants for winter by securing supports.
• Winter: Enjoy blooms and ensure trailing stems aren’t damaged by frost or heavy snow.
• Spring: Prune after flowering and feed to support new growth.
• Summer: Train young shoots and propagate through cuttings or layering.

Winter jasmine is an undemanding yet rewarding plant, perfect for brightening the darkest months of the year. With its cheerful blooms and adaptability, it’s a must-have for any UK gardener looking to extend their garden’s seasonal interest.
