How to Plant Rhubarb: Crowns vs. Seeds – A Comparative Approach

While it's technically possible to grow rhubarb from seeds, starting with crowns is the preferred method for most gardeners, especially beginners. Crowns, essentially the established root system of the plant, offer several key advantages: faster establishment, increased productivity, and reduced risk of failure.

• Planting Rhubarb Crowns: A Step-by-Step Guide

  1. Timing: Plant crowns in early spring or late autumn, after the ground has thawed but before the soil becomes too hard. Early spring planting is generally preferred in most climates.
  2. Preparation: Select healthy, plump crowns with multiple strong buds. Before planting, examine the crown for any signs of damage or disease. Discard any crowns that show signs of rot or disease.
  3. Planting Depth and Spacing: Plant crowns 2-3 inches deep, ensuring the buds are facing upwards. Maintain proper spacing—3-4 feet apart—to allow for adequate root development and air circulation. Proper spacing is crucial for maximizing yield and preventing disease.
  4. Soil Preparation: Amend the soil with plenty of organic matter (compost or well-rotted manure) to improve drainage, aeration, and nutrient content. The ideal soil pH for rhubarb is slightly acidic (6.0-6.8). A soil test can help determine your soil's pH and nutrient levels.
  5. Watering: Water the crowns thoroughly after planting. Maintain consistent moisture, especially during dry periods. Avoid overwatering, as this can lead to crown rot.

• Planting Rhubarb from Seeds: A More Challenging Path

  Growing rhubarb from seeds is a more time-consuming and less predictable approach. It typically requires starting seeds indoors 8-10 weeks before the last expected frost, transplanting seedlings outdoors after the danger of frost has passed. Germination rates can be unpredictable, and the plants may take longer to establish and produce a significant harvest. This method is generally not recommended for beginners.
