What are the horticulural aspects of Galium mollugo?

Galium mollugo grow in full sun to partial shade in moist soils with a pH range of 5.5-7.5. It thrives in a variety of habitats, including meadows, woodlands, and along streams. This adaptable plant can grow in a range of light conditions, from full sun to partial shade.

When planting Galium mollugo, choose a location with well-draining soil and full sun to partial shade. Sow seeds directly in the ground in early spring or fall, and keep the soil consistently moist during the germination period. Space plants about 12-18 inches apart to prevent overcrowding and promote healthy growth. Water regularly during the first growing season.

For optimal harvesting, wait until the stems are in flower, usually in mid-to-late summer. Cut the stems just above a node, using scissors or pruning shears.
