Rhubarb Cuttings: When and How to Take Them

by

Rhubarb is a popular perennial vegetable known for its tangy stalks used in desserts and jams. Propagating rhubarb through cuttings is an effective way to expand your garden. Knowing when and how to take rhubarb cuttings can ensure healthy new plants and a bountiful harvest.

When to Take Rhubarb Cuttings

The best time to take rhubarb cuttings is in early spring, just as the plant begins to emerge from dormancy. This is typically when the soil warms up and the plant shows signs of new growth. Avoid taking cuttings during the growing season or in late fall, as the plant is either actively growing or preparing to go dormant.

How to Take Rhubarb Cuttings

Follow these steps to successfully take and plant rhubarb cuttings:

  • Choose healthy stems: Select strong, healthy stalks that are at least one year old. Avoid diseased or damaged canes.
  • Prepare the cutting: Use a sharp, clean knife or pruning shears to cut a 4-6 inch section from the base of the plant, including a portion of the crown.
  • Remove excess leaves: Trim off the large leaves, leaving a few smaller ones if desired, to reduce moisture loss.
  • Plant the cutting: Insert the cut end into well-drained soil, burying about half of the stem. Space multiple cuttings at least 18 inches apart.
  • Water thoroughly: Water the newly planted cuttings generously to settle the soil and encourage root development.
  • Maintain and monitor: Keep the soil moist and place the planting area in a location with full sun. Avoid fertilizing until new growth appears.

Caring for New Rhubarb Plants

Once established, rhubarb plants require minimal care. Regular watering, especially during dry periods, and removal of any flower stalks will promote healthy growth. Mulching around the base can help retain moisture and suppress weeds. With proper care, your new rhubarb plants can produce stalks for many years.

Additional Tips

  • Take cuttings early in the season for the best rooting success.
  • Ensure the soil is rich in organic matter for optimal growth.
  • Avoid harvesting stalks from new plants until they are at least two years old.
  • If you notice any signs of disease, remove affected parts promptly.

By following these guidelines, you can propagate rhubarb successfully and enjoy fresh, homegrown stalks season after season.
