Why Is My Rhubarb Not Growing After Planting?

A rhubarb crown planted in autumn or winter that shows no sign of growth in its first weeks or months is not necessarily dead — it is often simply dormant, doing the quiet underground work of establishing roots before it expends energy on leaf production. However, there are a few genuine problems that can prevent or delay sprouting, and understanding when waiting is appropriate versus when something needs to be done is helpful for the anxious new rhubarb grower.

Dormancy — the most common explanation

Rhubarb crowns planted in autumn go dormant through winter and only produce growth when temperatures warm in late winter and early spring — typically February to March in the UK. If you planted in October and are checking in January, the crown is dormant. This is normal. A crown with at least one red bud node visible at the soil surface that has been in the ground through a UK winter should produce growth by March or April at the latest.

Planted too deep

Rhubarb buds need to be only just below the soil surface — 2–3cm at most. If the crown was planted too deeply (buds more than 5cm below soil level) the emerging shoots may struggle to push through. Carefully dig around the crown and check bud depth; if deeply buried, gently lift and replant at the correct depth.

Crown rot or physical damage

If a crown fails to emerge by late spring — and surrounding plants and soil temperature would normally support growth — gently excavate and inspect. A healthy crown is firm with white or pink internal tissue. A soft, brown, foul-smelling crown has rotted, likely from being planted in waterlogged or very cold heavy soil. This crown cannot be saved; order a replacement for autumn planting.
