Winterizing Rhubarb in Northern Minnesota

Rhubarb is extremely cold‑hardy (tolerates -20°F) and actually needs winter chill to trigger spring growth.

Winter Care Steps

1. After the first hard frost, cut remaining stalks and compost them.
2. Apply 3–5 inches of compost, leaves, or straw to protect roots from drying winds.
3. Water during winter droughts to keep roots hydrated.

Plants emerge as soon as the ground thaws. Late spring freezes may damage early leaves but won't kill the crown.
