Rhubarb thrives in consistently moist soil. Water deeply at the base of the plant, especially during dry spells and when actively growing. Avoid overhead watering to prevent fungal diseases.

Allow the top few centimeters of soil to dry slightly between waterings in cooler weather.

Pruning is mainly focused on removing dead or damaged foliage in late autumn or early spring. Avoid harvesting too late in the season to allow the plant to store energy for winter.

Remove flower stalks as soon as they appear, as they divert energy from leaf and stalk production.

Rhubarb is best propagated by division of established crowns. In early spring or autumn, carefully divide overgrown clumps using a sharp spade, ensuring each section has at least one bud and a healthy root system.

Replant divisions immediately into well-prepared soil.

Repotting is generally not applicable as rhubarb is a perennial that grows in situ.

Established clumps may become overcrowded after several years and benefit from division, which is a form of rejuvenation rather than traditional repotting. Aim to divide every 4-5 years.
