watering

Autumn crocus (Colchicum (group)) is a low maintenance, but water-loving flowering plant. It should be watered regularly throughout its growing season (generally late summer through fall). Water the plant thoroughly every 10-14 days during the growing season, allowing the soil to dry out slightly between waterings. Water should be applied to the soil surface until it begins to puddle and then is fully absorbed. Over-watering can lead to root rot, so make sure the soil drains well and that the plant is not standing in excess water. During winter dormancy, it is best to reduce watering and let the soil dry out.

sunlight

Autumn crocus, also known as Colchicum, require a full sun to light shade position in order to thrive. The plants prefer about 4 to 6 hours of direct sunlight each day, and can tolerate morning or late day sun. Ideally, morning sun is better to reduce moisture and summer heat during the hottest parts of the day. In shadier areas, the plant may need more frequent fertilizing and watering to keep it looking healthy. During the peak growing period of late spring and summer, the leaves need more intense sunlight, so if the sun is blocked for a few hours, the flowers and foliage may not reach their fullest potential. If the location is too shady, the plants may lack vigor and blooms.

pruning

Autumn crocus should be pruned in early spring, while the plant is still dormant. Start by cutting back the leaves to approximately 2.5 cm above the soil line. Remove any dead and decaying foliage, as well as any overcrowded stems. If the plant has grown up against a wall, fence, or other structure, prune to the desired height and width. To encourage a fuller appearance, try to retain as many flowering branches as possible. Lastly, remove any dead or damaged flower heads but avoid cutting healthy blooms.
