Care
Light exposure
Woodland cudweed thrives in part shade or light shade, recreating its natural woodland habitat. It also tolerates full sun if the soil remains sufficiently moist. Avoid overly harsh exposures in Mediterranean regions.
Soil and drainage
Plant this species in well-drained soil that is slightly acidic to neutral and low in fertility. It adapts well to poor and stony terrain. Excessive winter moisture can cause root rot: ensure impeccable drainage.
Watering
Water moderately after planting, then space waterings progressively. Once established, this plant tolerates drought thanks to its downy foliage which limits evaporation. In humid climates, minimal watering is sufficient; increase slightly during very dry summers.
Fertilization
Woodland cudweed requires no regular feeding on naturally poor soil. A very light application of well-decomposed compost in autumn is more than adequate. Excess nitrogen promotes lush foliage at the expense of flowering.
Pruning and cutting
Harvest flowers before full bloom if you wish to dry them for long-lasting bouquets. Light pruning after flowering maintains a compact shape and encourages new growth in spring. Simply remove any dried-out parts.
Health and pests
This plant is rarely troubled by diseases thanks to its protective foliage. Powdery mildew may appear in stagnant humid conditions: improve air circulation. Root rot is rare with proper drainage. No major pests typically affect it.
Did you know?
Woodland cudweed is among historically important textile plants: its tomentose leaves long served to line winter garments or to create candle wicks in regions without access to commercial candles. When dried, its small cream-white flowers retain their shape and colour for years, making it an ideal plant for traditional dried flower art.
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.
