Growth Stages
Dormancy (Winter)
December-FebruaryThe plant dies back completely above ground, with the crown remaining dormant underground. Frost exposure is essential for proper budbreak.
Reduce watering significantly. Allow leaf material to remain as mulch protection. No fertilizing needed. Mulch heavily if in colder zones.
Emergence (Spring)
March-AprilNew red shoots push through the soil as temperatures warm. Early emerging stalks are often the most vibrantly colored.
Remove mulch gradually as shoots emerge. Begin regular watering. Apply balanced fertilizer or compost around the base.
Vegetative Growth (Late Spring-Early Summer)
May-JuneThe plant produces numerous tall stalks with large leaves. Stalks are thickening and the plant is at peak vigor.
Water consistently. Fertilize every 3-4 weeks with nitrogen-rich fertilizer or diluted compost tea. Remove any flower buds that appear to direct energy to stalk production.
Flowering (Mid-Summer)
June-JulyIf not removed, tall flower stalks with greenish-cream colored flowers emerge from the center of the plant.
Pinch off flower buds as soon as they appear to prevent seeding and conserve plant energy for stalk production. Flowering significantly reduces stalk quality and yield.
Decline (Late Summer-Fall)
July-NovemberStalk production slows, leaf size increases, and stalks become thinner and less flavorful. The plant begins redirecting energy to the crown for winter storage.
Stop harvesting by mid-June to July to allow the plant to build energy reserves. Reduce fertilizing. Gradually reduce watering in late summer to encourage dormancy.
Common Pests
-
Hand-pick early morning, use row covers on young plants, apply neem oil or spinosad if infestation is severe
-
and
Remove debris and dense mulch habitat, use beer traps, apply diatomaceous earth, introduce predatory beetles
-
Destroy infested leaves and stalks, remove plant debris in fall, apply insecticidal soap for severe infestations
-
Increase humidity with regular misting, spray with water to dislodge, use insecticidal soap or neem oil if severe

Harvest Tips
Do not harvest in the first two years; wait until year 3 for full production. Harvest in spring and early summer (April-June in most areas). Pull stalks gently by twisting and tugging at the base rather than cutting with a knife. Harvest only 1/3 of the plant's stalks at a time. Stop harvesting by mid-June to mid-July to allow the plant to build crown reserves for next year. Stalks are ready when they're 12-18 inches long and fully colored.
Fun Facts
- 🌱 Canada Red rhubarb was developed in Canada in the early 1900s and is renowned for its bright red color that extends through the entire stalk, unlike many varieties that are only red near the base.
- 🌱 Rhubarb is technically a vegetable (the stalk is eaten) but is legally classified as a fruit in the United States for tariff purposes since it's primarily used in desserts.
- 🌱 A mature rhubarb plant can live 10-15 years or longer without replanting, making it one of the longest-producing perennial crops a home gardener can grow.
