Rhubarb planting calendar for Zone 5
Rhubarb is planted from dormant stock rather than sown, so it runs on a dormancy calendar instead of a sowing one.
Plant dormant stock
February–March
Zone 5's last frost lands around ~Apr 28, and dormant stock wants to be in the ground before the buds move — while the soil is workable but the plant is still asleep.
Winter hardiness
Zone 5 sits comfortably inside rhubarb's range (Zones 3–8), so no special winter protection is needed once the plant is established. A mulch ring still helps young plants through their first two winters.
Harvest timing for rhubarb: spring through early summer; stop by midsummer each year. Full planting, pruning and care detail is in the guide below.
