RhubarbRheum rhabarbarum

Rhubarb thrives in consistently moist soil. Water deeply, especially during dry spells, to encourage robust growth. Avoid waterlogged conditions, which can lead to root rot. Aim for about 2.

5 cm of water per week, applied at the base of the plant to keep foliage dry.

Remove spent flower stalks as soon as they appear to redirect energy into stalk production. In late autumn or winter, cut back all remaining foliage to the ground level.

This helps prevent disease overwintering and prepares the plant for vigorous spring growth. Old, withered leaves should be removed.

Rhubarb is typically propagated by division of established crowns. In early spring or autumn, carefully dig up a mature plant and divide the thick rhizomes into sections, ensuring each piece has at least one bud.

Replant divisions promptly in well-prepared soil.

Rhubarb is a perennial that is not typically repotted in the traditional sense.

Mature plants are divided and replanted in situ or in a new location, usually every 5-10 years, to rejuvenate them and maintain vigorous growth. This division process serves as a form of 'repotting'.
