Water Cycas taiwaniana thoroughly when the top 5-7 cm of soil feels dry. Allow the soil to dry out somewhat between waterings, as they are susceptible to root rot.

Reduce watering significantly during winter months when growth slows. Ensure good drainage to prevent waterlogging.

Pruning is minimal for Cycas taiwaniana. Remove only old, dead, or damaged fronds by cutting them close to the trunk. This promotes a clean appearance and redirects the plant's energy to new growth.

Avoid removing healthy fronds as they are essential for photosynthesis.

Propagation is primarily done through offsets (pups) that form at the base of the mature plant.

Carefully remove these offsets with a sharp, sterile knife when they are a reasonable size and have developed their own roots. Pot them in a well-draining mix and keep them slightly moist.

Repot Cycas taiwaniana only when it becomes root-bound, which is infrequent as they are slow-growing. Use a coarse, well-draining potting mix. Choose a pot that is only slightly larger than the current one.

Repotting is best done in spring, and handle the root ball gently.
