watering
For the best results, the autumn crocus should be watered deeply once every week during its active growing season. During hot summers, the soil should be kept moist but not overly wet. In the winter, autumn crocus should be watered very lightly, only enough to dampen the surface of the soil. It is important to give the plant a thorough soak every 2 weeks or so during the winter. This will help to keep the roots nourished without drowning them. It is also important not to let the plant sit in pooled water as this can cause rot and other fungal and bacterial issues. After flowering, the plant can be allowed to dry out a bit before regular watering resumes.
sunlight
Autumn crocus (Colchicum tenorei) prefers partial to full sunlight, but it should not be in direct sunlight for more than 4 hours a day. During the summer months, it can benefit from a few hours of direct sun in the morning or evening. In the winter months, when the sunlight is less intense, the plant can tolerate more than 4 hours of direct sun per day. However, it should be placed in a spot where it receives shade for part of the day. Placing the plant near a sun-facing window or in dappled sunlight should provide enough light for it to thrive.
pruning
Autumn Crocus (Colchicum tenorei) should be pruned in late winter or early spring, when the plant is still dormant before it begins its growth cycle in the spring. The pruning cuts should remove any dead foliage or weak shoots, and thin out the clumps of leaves and stems to create a more open and airy appearance. It is important to never prune more than 1-third of the plant at 1 time and to leave some foliage intact, as this helps to protect the plant and nourish it during the growing season. Pruning will also help to control the growth and size of the autumn crocus.
