Rhubarb is a hardy perennial that can produce abundant stalks for many years with proper care. Dividing and transplanting rhubarb helps maintain plant health and encourages vigorous growth. This guide provides step-by-step instructions to successfully divide and transplant your rhubarb.
When to Divide and Transplant Rhubarb
The best time to divide rhubarb is in early spring or late fall, when the plant is dormant. This minimizes stress and allows the plant to establish itself in its new location before the growing season begins. Avoid dividing during hot summer months, as this can cause undue stress to the plant.
Tools and Materials Needed
- Sharp garden spade or shovel
- Garden fork
- Garden gloves
- Clean pruning shears or knife
- Compost or organic matter
- Watering can or hose
- Mulch for new planting bed
Steps to Divide Rhubarb
Follow these steps to successfully divide your rhubarb:
1. Prepare the Plant
Water the rhubarb thoroughly a day before dividing to reduce stress and make digging easier.
2. Dig Around the Plant
Use a garden fork or spade to carefully loosen the soil around the base of the plant. Dig about 12 inches away from the crown to avoid damaging the roots.
3. Lift and Divide
Gently lift the entire plant out of the ground. Using clean shears or a knife, cut the crown into sections, each with at least one healthy bud and a good root system. Discard old, woody, or damaged sections.
4. Prepare the Divisions
Trim any damaged roots and leaves. Dip the cut sections in compost or organic matter to promote healthy growth.
Transplanting Rhubarb
Choose a sunny, well-drained location with rich soil for transplanting. Space divisions about 3 feet apart to allow for growth. Follow these steps for successful transplantation.
1. Prepare the New Bed
Clear the area of weeds and debris. Loosen the soil and mix in compost or organic matter to enrich the soil.
2. Plant the Divisions
Dig a hole large enough to accommodate the roots. Place the division in the hole so that the crown is just above soil level. Fill in with soil and gently firm around the roots.
3. Water and Mulch
Water thoroughly after planting to settle the soil. Apply a layer of mulch around the plant to retain moisture and suppress weeds.
Caring for Transplanted Rhubarb
Maintain consistent watering, especially during dry periods. Fertilize annually with compost or a balanced fertilizer. Remove any flower stalks to encourage leaf growth and root development.
With proper division and transplanting, your rhubarb will thrive and provide abundant harvests for years to come. Regular care and attention will ensure a healthy, productive bed.
