Soil and Site Preparation
Rhubarb prefers fertile, well-drained soil high in organic matter. Ensure the planting site is free from perennial weeds, as they can hinder rhubarb's growth. Cultivate the soil in spring and after cutting to maintain its condition. For optimal growth, aim for a slightly acidic to neutral pH (6.0–6.8). Adding compost or a balanced fertilizer each spring boosts soil fertility and improves crop quality.
Planting and Spacing
Space rhubarb roots 24–48 inches apart in rows 3–4 feet apart. For smaller gardens, reduce row spacing but avoid overcrowding to prevent disease. Plant roots with the crown bud 2 inches below the soil surface. Firm the soil around the roots but keep it loose over the buds. Raised beds help prevent crown rot in areas with poor drainage.
Care and Maintenance
Water rhubarb regularly to maintain vigorous growth. Remove flower stalks as they appear to direct energy to the plant. Avoid harvesting during the first year to allow roots to establish. Starting in the second year, stalks can be lightly harvested, increasing to full harvesting in subsequent years.
Harvesting Tips
Pull or cut stalks at the soil line and remove leaves, as they are toxic. Harvest selectively over 4–6 weeks to encourage continuous growth. With proper care, rhubarb will remain productive for 8–15 years.
Key Considerations
Rhubarb thrives in climates with winter dormancy (temperatures below 40°F) and moderate summer heat. While it can grow in southern regions, excessive heat may reduce stalk quality and color.
With its resilience and ornamental appeal, rhubarb is a fantastic addition to any garden. Enjoy its unique flavor in pies, sauces, and other culinary delights.
