Ornamental Rhubarb thrives in consistently moist soil. Water deeply when the top 2-3 cm of soil feels dry, especially during hot, dry periods. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly in winter when the plant is dormant.

Pruning is primarily for removing dead or damaged foliage. Cut back any withered or diseased leaves at the base of the plant in late autumn or early spring.

If the plant becomes overgrown, you can divide it during its dormant period to rejuvenate it.

Ornamental Rhubarb is best propagated by division. In early spring or autumn, carefully dig up established clumps and divide them into sections, ensuring each section has healthy roots and at least one bud.

Replant divisions immediately into well-prepared soil.

As Ornamental Rhubarb is a large, perennial plant, it is not typically repotted in the traditional sense for houseplants.

Established garden plants may benefit from division every 3-5 years to prevent overcrowding and maintain vigor. Select a new, suitably large location.
