Dividing rhubarb plants is an essential gardening practice that helps maintain healthy growth and ensures a reliable supply for harvesting. Proper division not only rejuvenates the plants but also enhances their storage ability, making it easier to enjoy fresh rhubarb throughout the year.
Why Divide Rhubarb Plants?
Over time, rhubarb plants can become crowded, leading to reduced vigor and smaller stalks. Dividing them allows gardeners to:
- Increase plant productivity
- Improve disease resistance
- Facilitate better storage and handling
- Create new plants for sharing or expanding your garden
Best Time to Divide Rhubarb
The optimal time to divide rhubarb is in early spring, just as the plant begins to emerge from dormancy, or in late fall after the foliage has died back. Dividing during these periods allows the new divisions to establish roots before extreme weather conditions.
Steps for Dividing Rhubarb
Follow these steps to successfully divide your rhubarb:
- Carefully dig around the base of the plant to expose the root crown.
- Use a sharp, clean spade or garden knife to cut through the root mass into sections, ensuring each division has at least one bud and a healthy root system.
- Remove any old, woody, or damaged roots from each division.
- Plant each division in a prepared bed with well-draining soil, spacing them about 3 feet apart.
- Water thoroughly after planting and mulch to retain moisture.
Preparing Divided Rhubarb for Storage
Proper preparation after dividing rhubarb enhances its storage ability. Follow these tips:
- Allow the freshly divided plants to establish in the soil for a season before harvesting to ensure they are vigorous.
- Harvest stalks only when they are mature, firm, and about 12-18 inches long.
- Cut the stalks close to the crown, leaving the leaves attached for a few days to allow the plant to recover.
Storing Rhubarb for Long-Term Use
Once harvested, rhubarb can be stored effectively by following these methods:
- Refrigeration: Wrap stalks in plastic or place in a perforated bag and store in the crisper drawer for up to two weeks.
- Freezing: Wash and cut stalks into manageable pieces. Blanch in boiling water for 1-2 minutes, then cool quickly in ice water. Drain well, pack into airtight containers or freezer bags, and store at 0°F (-18°C).
- Preserving: Make jams, jellies, or sauces to extend shelf life and enjoy rhubarb year-round.
Additional Tips for Successful Storage
To maximize storage ability, consider these tips:
- Use fresh, healthy stalks for better preservation.
- Label frozen packages with the date to keep track of storage time.
- Keep stored rhubarb away from strong odors to prevent flavor transfer.
- Check stored rhubarb regularly for signs of spoilage or freezer burn.
Conclusion
Dividing rhubarb plants is a simple yet effective way to promote healthy growth and improve storage capabilities. By choosing the right time, following proper division techniques, and employing effective storage methods, gardeners can enjoy fresh rhubarb for months and ensure their plants remain productive for years to come.
