Keep soil consistently moist during the growing season (fall through spring), especially when actively blooming. Reduce watering significantly once foliage begins to yellow and die back in late spring or early summer.

Avoid waterlogged conditions, which can lead to bulb rot.

Remove faded flowers immediately after blooming to prevent seed formation, which diverts energy from the bulb. Allow foliage to yellow and die back naturally before cutting it off.

This is crucial for the plant to store nutrients for future flowering.

Narcissus bicolor can be propagated by dividing overcrowded clumps every 3-5 years, typically after flowering and when the foliage has died back. Offsets (smaller bulbs that form around the parent bulb) can also be carefully separated and replanted.

Repotting is generally not necessary unless bulbs are overcrowded or need to be moved. If repotting is required, do so in late summer or early fall when the bulbs are dormant.

Plant them at a depth of about 10-15 cm in well-draining soil.
