Care

Exposure

Weld appreciates full sun to partial shade. Install it in a location receiving at least 6 hours of direct sunlight daily for abundant flowering. Light shade in hot climates can be beneficial.

Soil

This plant adapts to many soil types, but prefers well-drained, light and rather chalky substrate. Avoid overly compact or waterlogged soils. Adding compost at planting time promotes establishment.

Watering

Water moderately and regularly during the growing period, ensuring the soil doesn't dry out completely. Reduce watering in winter. Prefer slightly moist soil to waterlogged soil.

Fertilizing

Light fertilization in spring is generally sufficient. Diluted balanced fertilizer can be applied monthly during flowering. Avoid excess nitrogen which would promote foliage at the expense of flowers.

Pruning and cutting

Pinch young stems to encourage a bushy habit and better branching. Regularly remove faded flowers to extend flowering. At season's end, you can cut back the plant or let it go to seed as desired.

Health and pests

Weld is generally robust. Watch for aphids and spider mites in dry conditions. Good air circulation prevents fungal diseases. Intervene quickly if infestation occurs with gentle treatments.

Did you know?

Weld bears the name in reference to the shape of its radical leaves, though this is an old botanical confusion with other plants. Once cultivated in medieval gardens for its dyeing and ornamental properties, it inspired the famous Grimm fairy tale 'Rapunzel' which blends botany with popular literature.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
