When to plant
Plant rhubarb crowns in early spring as soon as the soil is workable, or in autumn while the soil is still warm. Autumn planting gives crowns extra time to root before winter.
Where to plant
Choose a sunny or lightly shaded spot with plenty of space — mature rhubarb plants can spread over 1 m wide. Avoid areas with standing water or very dry soil. Rhubarb is ideal for vegetable gardens, borders and unused corners of the plot.
Preparing the soil
Loosen soil to 30–40 cm and enrich generously with compost or well-rotted manure. Rhubarb thrives in deep, fertile, moisture-retentive but well-drained soil. Improve sandy soils with compost, and lighten clay with grit and organic matter.
Preparing the crowns
Inspect crowns and remove any soft or damaged sections. If crowns are large, they can be divided, but only when dormant. Do not soak rhubarb crowns before planting.
Planting the crowns
Plant crowns so that the top sits 3–5 cm below soil level. Space plants 90–120 cm apart to accommodate their mature size. Firm the soil gently and water well after planting.
After planting
Keep the soil consistently moist during the first season. Mulch with compost or well-rotted manure to retain moisture and feed the plant, keeping mulch away from the crown itself to avoid rot.
During growth
Water during dry periods, especially in spring and early summer. Remove flower stalks as soon as they appear to keep the plant productive. Do not harvest in the first year — allow the crown to establish.
After flowering / End of season
Cut back old stems after frost. Rhubarb dies back naturally in winter. In very cold climates, apply a layer of mulch to protect the crown.
Extra tips
Never eat rhubarb leaves — they are toxic.
Divide crowns every 5–8 years to rejuvenate growth.
For thick, tender stems, feed annually with compost or manure in early spring.
