Expert tips
The key tip
Ampelopsis climbs fast (4-5 meters in 3-4 years) but prefers fertile, well-moistured soil. Prune hard in winter to stop it from taking over: it doesn't know when to quit and strangles its neighbors.
The common mistake
People let it sprawl freely thinking it makes a nice screen.
The pro's trick
Train the main stems horizontally on a frame or pergola: it spreads better and branches more than if you let it climb vertically on its own.
Seasonal watch
Fall: its pale blue berries attract birds that spread the plant everywhere.
Care
Exposure
Plant in full sun for optimal fruiting and beautiful fruit coloration. Ampelopsis brevipedunculata also tolerates partial shade, but will flower and fruit less abundantly. Ideal on a well-exposed trellis, pergola, or fence.
Watering
Water regularly during the first year of establishment to promote rooting. Once well established, the plant is fairly drought-tolerant but appreciates slightly moist soil during the growing season. Reduce watering in winter.
Soil type
Ampelopsis prefers well-drained, fertile soil rich in organic matter. It adapts to acidic to neutral pH. Improve poor soil by incorporating well-decomposed compost when planting.
Pruning and training
Prune in late winter or early spring to control its vigorous growth and limit spreading. Remove dead or poorly oriented branches. You can also prune lightly in summer to guide stems toward your support.
Fertilizer
Apply balanced fertilizer in spring to support growth. Excessive fertilization promotes foliage at the expense of fruiting. An annual application of compost on the surface is generally sufficient for good vigor.
Pests and diseases
Ampelopsis brevipedunculata is generally robust. Watch occasionally for spider mites in very dry, hot climates. Powdery mildew can appear in overly humid conditions: promote good air circulation and avoid leaf watering.
Did you know?
The blue fruits of Ampelopsis brevipedunculata are a remarkable fall display, transitioning from green to turquoise blue before turning dark grape. This plant is a less well-known botanical relative of cultivated grapevine, but unlike its viticultural cousins, its small tart berries are not intended for winemaking and are rather appreciated by migratory birds.
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.
