Care

Exposure and light

Provence bindweed requires full sun for generous flowering. Place it in a location bathed in direct light for at least 6 to 8 hours per day. A south or west-facing exposure is ideal to encourage growth and flower production.

Watering

Once established, this plant is very drought-resistant. Water moderately and regularly during the first year of planting. After that, limit watering to periods of prolonged heat. Let the soil dry out between waterings.

Soil

Bindweed appreciates light, well-drained and poor soil, thus avoiding excess foliage at the expense of flowers. Enrich the soil sparingly at planting. Chalky or slightly acidic soil works perfectly.

Pruning and training

Prune after flowering or in late winter to manage its vigorous growth and encourage branching. Remove dead or diseased wood. A support (trellis, pergola) is essential to direct its climbing nature.

Fertilizer

Apply balanced or low-nitrogen fertilizer once or twice during the growing season. Excess fertilizer promotes foliage at the expense of flowering. Prefer moderate applications.

Pests and diseases

Provence bindweed is generally resistant. Watch for spider mites in hot, dry climates. Soil that is too moist can promote root rot. Ensure good drainage and air circulation to prevent fungal issues.

Did you know?

Provence bindweed is a classic feature of Mediterranean gardens where it covers walls and pergolas with its elegant pale pink flowers. Its genus Convolvulus comes from the Latin "convolvere" meaning "to twine around," referring to its twining stems that spiral around any support. Long confused with Convolvulus tricolor, it remains a botanical treasure of warm, dry regions.

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.
