If your rhubarb plant starts to flower, you should remove the flower stalk immediately. Producing a flower takes significant energy away from the plant and can reduce the quality and yield of the edible stems. Simply cut the flowering stalk at the base as soon as you notice it.

Rhubarb prefers fertile, well-drained soil that is rich in organic matter. Before planting, it is beneficial to dig in plenty of well-rotted manure or garden compost. The soil should hold moisture well but must not become waterlogged, as this can cause the crown to rot.

Mature rhubarb plants should be lifted and divided every five to six years to maintain their vigour. This task is best performed in autumn or winter when the plant is dormant. Splitting the crown ensures the stalks remain thick and prevents the plant from becoming overcrowded.

Forcing involves covering the rhubarb crown with a large pot or bin in late winter to exclude light. This encourages the plant to produce pale, tender, and sweeter stems earlier than unforced plants. Remove the cover once the stems reach the top of the container to allow normal growth.

No, you must never eat rhubarb leaves as they contain high levels of oxalic acid, which is toxic to humans and animals. Only the stalks are edible and safe for consumption. Always trim the leaves off and discard them on your compost heap.

Do not harvest any stems during the first year after planting to allow the plant to build up energy reserves. In the second year, you may pick a few stems lightly to avoid stressing the crown. From the third year onwards, you can harvest normally from spring until mid-summer.

Rhubarb thrives best in a sunny position but will tolerate partial shade. It requires an open site that is free from frost pockets to prevent damage to early emerging stems. A spot with at least six hours of sunlight typically produces the strongest yields.

Rhubarb crowns are best planted in autumn or early spring while the plant is dormant. This timing allows the roots to establish thoroughly before the active growing season begins. Avoid planting when the ground is frozen or waterlogged to prevent damage to the crown.
