watering
Autumn crocus should be watered when the soil has dried out - usually every 5 to 7 days. Water deeply to ensure that the soil has been thoroughly moistened, but then avoid wetting the foliage or other parts of the plant. It is recommended to water in the morning, as this gives the plant time to dry off before nightfall. During the summer, it may be necessary to water more frequently.
sunlight
Autumn Crocus (Colchicum autumnale 'Pleniflorum') will do best in a sunny location that receives 6-8 hours of direct sunlight each day. Full sun exposure is best for blooms during the fall. During the summer months, provide a partial or filtered sun location, which will help the plant conserve its energy. These plants also require ample drainage, as they are sensitive to overwatering.
pruning
Autumn crocus (Colchicum autumnale 'Pleniflorum') should be pruned in spring or early summer right after it blooms. Pruning can involve removing any dead or wilted leaves, and cutting off spent flowers. If the plant is in a container, it should also be pruned to keep it at a manageable size. Make sure to use sharp, clean pruning shears to avoid damaging the plant. Pruning can help ensure a healthy blooming season the next year and control the size and shape of the plant.
