Expert tips
The key tip
Muehlenbeckia complexa climbs and cascades elegantly. Water regularly during growth, then reduce significantly from September onwards.
The common mistake
Keeping it moist year-round like a tropical plant: it survives outdoors but slowly declines.
The pro's trick
Prune hard after winter (February-March): this forces the plant to branch low and develop a beautiful dense form.
Care
Exposure
Install the wire vine in full sun for optimal growth and dense foliage. It tolerates partial shade but will be less vigorous. Protect it from strong winds that can damage its thin stems.
Watering
Water regularly during the growing period (spring-summer), keeping the soil moist but not waterlogged. Reduce watering in autumn and winter. Apply mulch to retain moisture.
Soil and planting
Plant in well-draining soil enriched with compost. This plant tolerates poor and sandy soils. Avoid waterlogging in winter, which promotes rot.
Pruning
Prune lightly after flowering to maintain its shape and control growth. Remove dead or damaged stems in spring. Regular pruning encourages branching.
Fertilizer
A balanced fertilizer application in spring is generally sufficient. Avoid excess feeding, which encourages foliage at the expense of flowering.
Health
Generally hardy, it can be affected by rot if the soil is too moist. Check for the absence of scale insects. Good air circulation prevents most problems.
Did you know?
Muehlenbeckia complexa owes its nickname of 'wire vine' to its extraordinarily thin and sinuous stems, which maintain their graphic structure even in winter. Native to New Zealand, this plant was once highly prized by Victorian gardeners for covering delicate structures and creating refined geometric effects as espaliered specimens.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
