Care
Light exposure
Woodruff thrives in part shade or partial shade, beneath shrubs or trees. It also tolerates dappled light. Avoid harsh sun in warm regions.
Watering
Keep the soil fresh and moist during growth, especially in the first year. Once established, it tolerates moderate dry periods well. Water after planting and during prolonged hot spells.
Soil
Prefer well-drained soil rich in organic matter, with a slightly acidic tendency. Adding compost at planting time promotes establishment and growth.
Pruning
Low maintenance pruning required. Light cutting back in spring helps maintain a compact shape. You can also let the plant grow naturally in a wild garden setting.
Fertilizing
An annual application of compost or organic fertilizer in spring is more than sufficient. Avoid excessive nitrogen inputs that would encourage lush foliage at the expense of flowering.
Diseases and pests
Woodruff is a hardy plant with little susceptibility to common diseases. In overly wet and poorly aerated soil, watch for root rot. Good drainage prevents these issues.
Did you know?
Woodruff belongs to the Rubiaceae family, the same as the coffee plant and madder. Historically, several woodruff species were used to obtain natural red or yellow dyes. Its small, discreet flowers attract pollinators and offer precious wild charm to shaded gardens.
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.
