Growing Rhubarb in Zone 2A

Rhubarb is one of the few true perennial vegetables, returning every spring for 10-15 years. Patience is required — don’t harvest in year one.

Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Never eat the leaves — they contain oxalic acid and are toxic
• Do not harvest any stalks the first year; take lightly the second year
• Red varieties tend to be sweeter and less tart than green ones
• Divide clumps every 4-5 years to keep production vigorous
• Mulch heavily in fall to protect the crown over winter

Companion Planting

Good companions: strawberries, garlic, onions

Avoid planting near: dock, knotweed (same family)

Harvest Timeline

Year 3+ — pull stalks when 12-18 inches long; stop harvesting after early summer
