Care
Watering
Water regularly during the growing season, especially during dry spells. Once established, wild mallow tolerates drought well thanks to its deep root system. Avoid excess water which would encourage fungal diseases.
Exposure
Plant wild mallow in full sun for abundant flowering. It tolerates partial shade but will flower less profusely. A well-ventilated spot prevents moisture-related problems.
Soil and preparation
Wild mallow adapts to most soils, even poor or stony ones. Well-drained soil is essential to prevent root rot. A moderate addition of compost improves soil structure at planting time.
Pruning and maintenance
Prune lightly after flowering to encourage a compact shape and additional flowering. Remove spent flowers regularly to extend the blooming period. In late winter, remove dead or damaged stems.
Fertilizer
Wild mallow is undemanding in terms of nutrients. A balanced fertilizer application in spring is quite sufficient. Avoid excess nitrogen which causes excessive growth at the expense of flowering.
Diseases and pests
Watch for rust and powdery mildew in excessively humid conditions. Spider mites may appear in very dry conditions. Good air circulation and watering at the base limit these problems.
Did you know?
Wild mallow has been used since antiquity in European herbalism. The ancient Greeks and Romans consumed it regularly for its soothing properties, and Hippocrates already mentioned it in his medical treatises. Its pale mauve-pink flowers also inspired medieval dyers.
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.
