Efficiently Dividing Rhubarb Crowns- A Comprehensive Guide to Splitting Your Rhubarb Plants

Can you split rhubarb crowns? This is a common question among gardeners who are looking to propagate their rhubarb plants or simply want to increase their stock. Rhubarb, known for its tart and tangy taste, is a popular vegetable that can be used in a variety of dishes, from pies and jams to salads and smoothies. Splitting rhubarb crowns is a straightforward process that can help you expand your rhubarb garden or share your favorite plants with friends and family.

Rhubarb crowns are the root systems of rhubarb plants, and they can be divided to create new plants. This process, known as crown division, is essential for the health and vitality of your rhubarb plants. Over time, rhubarb crowns can become overcrowded, leading to reduced yields and potential disease issues. By splitting the crowns, you can ensure that each plant has enough space to grow and thrive.

Before you begin splitting rhubarb crowns, it’s important to understand the best time to do so. Rhubarb should be divided in late winter or early spring, just before the new growth begins. This timing allows the plants to recover and establish themselves before the growing season. To split the crowns, you will need a sharp garden spade or knife, a clean cutting surface, and a few other gardening tools.

Here’s a step-by-step guide on how to split rhubarb crowns:

1. Prepare the Garden: Choose a sunny location with well-draining soil. Rhubarb prefers full sun but can tolerate partial shade.

2. Dig Up the Crowns: Using a garden spade, dig around the rhubarb plant, being careful not to damage the roots. Once you have a clear area around the plant, lift the entire crown out of the ground.

3. Inspect the Crowns: Examine the rhubarb crowns for any signs of disease or damage. Remove any dead or unhealthy roots, as these can spread to the new plants.

4. Split the Crowns: Using a clean, sharp knife or garden spade, cut the crowns into sections. Each section should have at least one healthy bud (the point where the new growth will emerge) and a good amount of roots. Aim for sections that are about 1-2 inches thick.

5. Plant the New Crowns: Dig a hole for each new crown, ensuring that the bud is at soil level. Place the crown in the hole, spreading out the roots, and backfill the soil around it. Firm the soil gently to remove air pockets.

6. Water and Mulch: Water the newly planted crowns thoroughly and apply a layer of mulch to help retain moisture and keep the soil temperature stable.

7. Caring for the New Plants: After splitting the crowns, it’s important to care for the new plants. Water them regularly during dry spells and keep the area free of weeds. In the first growing season, avoid harvesting the leaves to allow the plants to establish themselves.

By splitting rhubarb crowns, you can enjoy a larger harvest and share your favorite plant with others. This simple process can help you maintain a healthy and productive rhubarb garden for years to come. So, the answer to the question “Can you split rhubarb crowns?” is a resounding yes!
