Rhubarb is a long-lived perennial that produces tart, flavorful stalks for 10-15 years. Choose a variety like Victoria, Crimson Cherry, or Valentine. Plant in full sun (6-8 hours) with well-draining, rich soil (pH 6.0-6.8). Space plants 3-4 feet apart in rows 4-5 feet apart. Water deeply (1-2 inches per week), mulch heavily, and fertilize in spring. Do NOT harvest in the first year—let plants establish. Harvest stalks 10-15 inches long by pulling and twisting (do not cut). Only eat the stalks—leaves are toxic. Rhubarb is cold-hardy and perfect for pies, jams, and crumbles.
What you will need
Choose the Right Rhubarb Variety
Victoria: Classic heirloom variety. Green stalks with pink blush. Reliable and productive. Tart flavor. Good for beginners.
Crimson Cherry: Deep red stalks. Sweeter than green varieties. Excellent for pies and jam. Good for home gardens.
Valentine: Bright red stalks, very sweet, and flavorful. Great for fresh eating and cooking.
Canada Red: Deep red stalks with excellent flavor. Cold-hardy and productive. Good for northern climates.
Which is best? For beginners: Victoria (reliable) or Valentine (sweet, red). For cold climates: Canada Red or Victoria.
Select the Best Planting Site
Sunlight: Rhubarb needs 6-8 hours of direct sunlight daily. It can tolerate light shade but produces best in full sun.
Soil: Rhubarb prefers well-draining, rich, loamy soil with a pH of 6.0-6.8. Add plenty of compost or aged manure.
Drainage: Good drainage is critical—rhubarb roots rot in wet soil. If you have heavy clay, plant on raised beds.
Space: Rhubarb is a large plant. Give each plant 3-4 feet of space. They don't like to be crowded.
Winter hardiness: Rhubarb is very cold-hardy (USDA zones 3-8) and needs a winter chilling period to produce well.
Plant Rhubarb Correctly
When to plant: Plant in early spring (as soon as the ground can be worked) or fall. Bare-root crowns are best planted in spring.
Planting depth: Plant crowns so the buds are 1-2 inches below the soil surface. The top bud should be just at soil level.
Spacing: Space plants 3-4 feet apart in rows 4-5 feet apart. Rhubarb plants get large.
Soil preparation: Dig a large hole and mix in plenty of compost or aged manure. Rhubarb is a heavy feeder.
Watering after planting: Water deeply to settle the soil around the roots.
Water and Mulch
Water: Rhubarb needs 1-2 inches of water per week, especially during dry spells. Consistent moisture is essential for tender stalks.
Mulch: Apply 3-4 inches of mulch (straw, wood chips, or compost) around the plants. Mulch suppresses weeds, retains moisture, and keeps the soil cool.
Keep away from the crown: Don't pile mulch directly against the crown. Leave a 2-inch gap to prevent rot.
Weed control: Rhubarb is shallow-rooted. Hand-pull weeds near the plants to avoid root damage.
Fertilize Properly
When to fertilize: Apply fertilizer in early spring before growth starts. Also apply after harvest to support next year's growth.
What to use: Use a balanced fertilizer (10-10-10). Apply 1/2 to 1 cup per plant in spring. Organic options: compost, aged manure, or fish emulsion.
How much: Rhubarb is a heavy feeder—don't skimp on fertilizer. Too little fertilizer = thin stalks.
Side-dress: Side-dress with compost or manure in late spring to boost growth.
Signs of nutrient deficiency: Yellowing leaves (nitrogen) or poor stalk growth.
Manage Flowers and Runners
Removing flower stalks: Rhubarb produces flower stalks in spring. Cut them off immediately to direct energy to stalk growth.
Why remove: Flowering weakens the plant and reduces stalk production.
Runner control: Rhubarb spreads by underground runners. If you want to keep your patch contained, pull or dig up runners.
Division: Every 3-4 years, divide rhubarb crowns in early spring to rejuvenate the patch.
Harvest Rhubarb Correctly
When to harvest: Harvest in spring and early summer (April-June). In the first year, do NOT harvest. In the second year, harvest lightly.
How to harvest: Grasp the stalk at the base, pull and twist gently. The stalk should come away cleanly from the crown.
What to harvest: Only harvest stalks that are 10-15 inches long and 1 inch thick. Leave the rest to grow.
How much: Harvest 1/3 to 1/2 of the stalks at a time. Leave enough for the plant to recover.
Stop harvesting: Stop harvesting in early summer to allow the plant to store energy for next year.
Protect from Pests and Diseases
Crown rot: Caused by wet soil. Improve drainage and avoid overwatering.
Leaf spot: Fungal disease. Remove affected leaves and improve air circulation.
Aphids: Spray with insecticidal soap or neem oil.
Slugs: Set beer traps or use diatomaceous earth.
Deer and rabbits: Protect young plants with fencing or netting.
Common problems and fixes
| Problem | Likely cause | What to do |
|---|---|---|
| Thin, spindly stalks | Lack of water or nutrients, or overcrowding. | Water deeply, fertilize, and thin overcrowded plants. |
| No stalks in spring | Crown rot or damage. | Check for rot, improve drainage, and protect from winter damage. |
| Leaves turning yellow | Overwatering or nutrient deficiency. | Water less and apply balanced fertilizer. |
| Flower stalks appearing | Stress or natural aging. | Remove flower stalks immediately to focus energy on stalk growth. |

Common questions
Can you eat rhubarb leaves?
No. Rhubarb leaves contain oxalic acid, which is toxic and can cause serious illness. Only the stalks are edible.
Why does my rhubarb flower?
Flowering is natural but reduces stalk production. Remove flower stalks immediately to encourage more leaf and stalk growth.
Can I grow rhubarb in containers?
Yes, but use a large container (15-20 gallons) and choose a compact variety. Water and fertilize regularly.
How do I divide rhubarb plants?
Divide in early spring every 3-4 years. Dig up the crown, separate into sections with at least one bud, and replant.
How much water does rhubarb need?
Rhubarb needs 1-2 inches of water per week. Consistent moisture is essential for tender stalks.
Rhubarb is a long-lived, low-maintenance perennial that produces delicious tart stalks for pies, jams, and crumbles. Plant it in full sun, water consistently, and fertilize regularly. Do NOT harvest in the first year—let the plant establish. In the second year, harvest by pulling and twisting stalks at the base. Remove flower stalks to keep energy focused on stalk production. With proper care, your rhubarb patch will produce for 10-15 years and become a cherished part of your garden.
Frequently asked questions
How often should a vegetable garden be watered?
Frequency depends on weather, soil and plant size. Check the soil rather than watering on a rigid schedule.
Is compost enough fertilizer?
Compost improves soil and provides nutrients slowly. Heavy-feeding crops may still need additional feeding.
