high mallow

Malva sylvestris

High mallow (Malva sylvestris) is an herbaceous perennial wildflower native to Europe, North Africa, and Asia. It is a bushy, upright plant with oval leaves and yellow-green to white, 5-petaled flowers that attract bees and butterflies. It is tolerant of a variety of soils and does best in full to partial sun. Easily grown from seed, high mallow has a long bloom time from mid-spring to early fall. Sometimes known as tall mallow, this stately plant adds grace and beauty to meadows and wildflower gardens. Its flowers can also be dried and used to make tea.

watering

High mallow (Malva sylvestris) should be watered regularly but not over-saturated with water during the growing season. Watering should be deep but infrequent, and take place 1-2 times per week to start. As the summer progresses and soil dries out more quickly, additional watering may be needed (3-4 times per week). When watering, it’s important to thoroughly saturate the soil with a slow trickle of 2-3 gallons of water, allowing the moisture to absorb as far down as possible. During periods of extended drought or heat, additional watering may be required, however, avoid over-watering as this can lead to root rot. In late summer, as high mallow begins to enter a dormant phase, gradually reduce the frequency of watering, allowing the soil to dry out between applications.

sunlight

High mallow (Malva sylvestris) is a plant species that grows best in full sun, requiring 6-8 hours of direct sunlight per day to thrive. The amount of light will decrease in the winter, but the plant should still receive some amount of sunlight, even in the coldest climates. The plant should not be exposed to direct sunlight during peak summer temperatures, as this could lead to sunburn damage. To prevent this, it is best to provide the high mallow with some shade during the hottest part of the day. Additionally, high mallow should not be exposed to temperatures below freezing or to prolonged periods of drought.

pruning

High mallow (Malva sylvestris) should be pruned once per year in early spring before new growth begins, or right after flowering. When pruning, remove dead and diseased stems, thin out overcrowded stems, and cut back tall ones by half to keep the plant compact. This encourages new, healthy growth and should be done regularly to keep the plant in optimal shape.
