Water Ranunculus illyricus regularly during its active growth period, ensuring the soil remains consistently moist but not waterlogged. Reduce watering significantly as the foliage begins to yellow and die back in summer, allowing the tubers to dry out slightly to prevent rot before dormancy.

Remove spent flowers regularly to encourage more blooms and prevent seed formation. Cut back yellowing and dying foliage in late summer or early autumn after the plant has finished flowering and begun its dormancy.

This helps maintain plant health and tidiness.

Ranunculus illyricus is typically propagated by dividing its tubers in late autumn or early spring before new growth begins. Carefully separate the fleshy tubers, ensuring each piece has at least one 'eye' or bud.

Plant divisions shallowly in well-draining soil.

Repot tubers of Ranunculus illyricus if they are overcrowded in their current container, typically every 2-3 years. This is best done in autumn or early spring.

Use a well-draining potting mix and plant the tubers just below the surface of the soil.
