Care
Watering
Water moderately and regularly during the growing period, keeping the soil slightly moist. Reduce watering in case of prolonged drought, as this plant tolerates dry periods well once established. Avoid waterlogging at all costs, as it promotes rot.
Light Exposure
Plant Filago germanica in full sun for optimal growth and abundant flowering. This plant thrives in warm, bright conditions. It tolerates shade poorly and etiolates quickly in low light.
Soil and Substrate
Prefer well-draining, light, and rather poor soil: this species dreads stagnant moisture. A mixture containing sand or pumice improves drainage. On compact garden soil, loosen and improve drainage before planting.
Fertilization
Filago germanica requires minimal fertilization. A balanced fertilizer application in spring is more than enough. Avoid excess nitrogen, which promotes foliage at the expense of flowering.
Pruning and Cleanup
No real pruning is necessary. Simply remove faded flowers to prolong flowering and prevent excessive self-seeding. At the end of the season, after senescence, eliminate dried stems.
Pests and Diseases
Filago germanica is rarely affected by diseases thanks to its hardiness. Powdery mildew may appear in warm, humid conditions. Ensure good ventilation and avoid wetting the foliage. Insect attacks are rare and generally harmless.
Did you know?
Filago germanica, called "German Filary" or "Cottony Cudweed", owes its greyish appearance to a fine, very dense white down covering stems and leaves. This remarkable botanical adaptation reflects excess sunlight and reduces evapotranspiration, allowing the plant to thrive in dry, rocky areas. Formerly, certain Filago species were used in traditional herbalism, though this use has fallen out of favor.
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.
