Western Least Moonwort

Watering for Western Least Moonwort (Botrychium simplex var. compositum) should be done sparingly. Water lightly during the spring and summer months, when the plant is actively growing. Be sure to soak the soil, but not to the point of sogginess. Avoid overwatering, as this can lead to fungal problems. In the fall and winter, water occasionally but do not let the soil dry out completely. A once-monthly watering should be sufficient at this time.

Western Least Moonwort (Botrychium simplex var. compositum) grows best when it receives partial shade, ideally morning or evening sunlight. In order for this moonwort species to thrive, it should receive at least 3-4 hours of direct sunlight per day, preferably during the middle of the day when the sun is at its highest point. If possible, avoiding intense afternoon sunlight is ideal for this species. Additionally, it's important to avoid too much shade, as this species needs significant light to express its variegation in foliage.

Western least moonwort (Botrychium simplex var. compositum) should be pruned in late winter or early spring. The plant doesn’t require significant pruning but should be cut back to the ground near the end of the dormant season. This will encourage new growth and development in the spring. Pruning should remove only the dead, damaged or overcrowded parts and should not be excessive or invasive.
