Moving rhubarb crowns can be done to rejuvenate the plants and ensure healthier growth. It is best to carry out this task every 5 or 6 years between the months of November and March when the plant is dormant. During this period, the rhubarb is less likely to experience transplant shock and has a better chance of establishing itself in its new location.
To start, you will need a spade or garden fork to lift each rhubarb crown from the ground. It is important to dig deep and wide around the crown to avoid damaging the roots. Once the crown is lifted, it can be divided into 3 or 4 separate pieces. Dividing the crown helps to stimulate new growth and can lead to stronger, healthier plants.
When dividing the crown, it is crucial to ensure that each piece has a healthy-looking bud. This bud will serve as the growth point for next year’s new shoots. If a piece of the crown does not have a bud or appears unhealthy, it is best to discard it to prevent any potential problems.
After dividing the crown, it is time to replant each piece separately. Choose a new location that provides adequate sunlight and well-draining soil. Dig a hole wide and deep enough to accommodate the roots of each divided piece. Place the piece in the hole, making sure the bud is facing upwards and the crown is level with or slightly above the soil surface.
Once all the divided pieces are replanted, it is important to water them thoroughly. This will help settle the soil and promote root establishment. It is also necessary to provide regular watering throughout the growing season, especially during dry periods.
In the first year after moving the rhubarb crowns, it is advisable to avoid harvesting any stalks. This allows the plants to focus on establishing their roots and developing new growth. However, in subsequent years, you can resume harvesting stalks, ensuring you do not take more than a third of the plant’s stalks at a time to avoid weakening it.
Moving rhubarb crowns can be a rewarding task as it rejuvenates the plants and promotes healthier growth. By following the recommended timing, dividing the crowns carefully, and providing proper care after transplanting, you can enjoy a thriving rhubarb patch for years to come.
