When to plant Rhubarb?

Rhubarb thrives in full sun or partial shade and prefers a rich, moisture-retentive soil with good drainage. Loam and clay soils suit it well, provided they don't become waterlogged in winter. Choose a permanent spot, as established rhubarb crowns can crop for ten years or more and dislike being moved. Plant rhubarb crowns (dormant root sections with at least one bud) in March, April, October, or November. Autumn planting allows roots to establish before winter, while spring planting suits heavier soils that stay cold and wet. Prepare the site by digging in plenty of well-rotted manure or garden compost to a depth of at least 30 cm, as rhubarb is a hungry feeder. Space crowns 90 cm apart to allow for their eventual spread of 80–120 cm. Plant each crown so the tip of the bud sits just below the soil surface—about 2–3 cm deep. Planting too deeply can cause the bud to rot; too shallow and frost may damage it. Firm the soil gently around the crown and water in well, even if planting in autumn. After planting, apply a 5 cm layer of well-rotted manure or compost around (but not directly over) the crown to suppress weeds and feed the soil. Keep the area weed-free, especially in the first year, as young rhubarb doesn't compete well. Water during dry spells in the first growing season to help roots establish. Avoid harvesting any stems in the first year; let the plant build strength. In the second year, take only a few stems, then harvest freely from year three onwards.
