How to Propagate Rhubarb: A Beginner’s Guide
How to Propagate Rhubarb?
To propagate rhubarb, the best method is to divide the existing crown.
Dig up the crown and carefully split it into sections, making sure each section has 1-3 buds and roots.
Discard any tough material from the center.
Replant the smaller crowns in moist, fertile soil and water well.
It is advised not to harvest from the divided sections in the first year.
In the second year, only take a few stalks.
Established plants that are three or more years old can be harvested from spring onwards when the stalks are between 30-60cm long.
Remember to harvest by pulling and twisting the stems off the plant.

Forced Rhubarb: How To Get An Early Crop
Rhubarb, with its vibrant red stalks and tart flavor, is a popular addition to many recipes. Did you know that you can enjoy this delicious vegetable even earlier in the year by forcing it? Forced rhubarb refers to the practice of covering the crowns in late winter to harvest stalks as early as March. Here’s how you can achieve an early crop of rhubarb.
To force rhubarb, it’s important to cover the crowns in early winter to stop light from reaching the emerging stems. This can be done by using a bin, bucket, or a traditional terracotta rhubarb forcer. The lack of sunlight triggers the plant to grow longer, thinner stalks that are tender and sweeter in taste.
If you want to enjoy forced rhubarb indoors, you can lift the crowns from the ground in November. Let them chill for two weeks to simulate a period of dormancy. Then, pot them up in compost and move them into a cool indoor spot. This will encourage the rhubarb to grow and produce an earlier crop.
It’s worth noting that forcing rhubarb should be done on well-established plants. While forced rhubarb plants may not produce much of a crop later on, they can be divided and replanted in the summer to continue the cycle of growing this delightful vegetable.
Planting Rhubarb: Tips For Soil, Space, And Watering
To successfully propagate rhubarb, it’s crucial to provide it with the right growing conditions. Rhubarb plants thrive in fertile, free-draining soil with added organic matter. When preparing the soil, incorporate compost, manure, or leaf mould to improve its fertility. Ensuring the soil remains moist is essential, especially during dry periods, as rhubarb requires consistent watering.
When choosing a site for planting rhubarb, look for an open, sunny or partially shaded area with rich, moist soil. While rhubarb can be grown in containers, it generally produces better results when planted directly into the ground. The plants need plenty of space to spread out and grow, allowing their impressive leaves to capture sunlight for optimal growth.
It’s worth noting that the foliage of rhubarb is toxic to cats, dogs, horses, and people. Take precautions to keep any curious pets away from the plants, and for humans, avoid consuming the leaves or using them in culinary preparations.
Rhubarb Propagation: Using Crowns And Seeds
When it comes to propagating rhubarb, the most effective method is using rhubarb crowns. Rhubarb crowns, which are sections of mature rhubarb plants, can be planted in late autumn to establish new plants. Here’s how to do it:
- Dig up existing crowns and split them into sections with 1-3 buds each.
- Make sure each section has roots and discard any tough material from the center.
- Replant the smaller crowns in moist, fertile soil and water them well.
Alternatively, rhubarb can also be grown from seed. However, the quality and consistency of the resulting plants can vary significantly compared to using rhubarb crowns. If you choose to start from seed, keep the following in mind:
- It requires patience and extra care in nurturing the young plants until they are ready for transplanting.
When propagating rhubarb, remember that it’s advisable not to harvest from the divided sections in the first year. During the second year, only take a few stalks. Established plants that are three or more years old can be harvested from spring onwards when the stalks are between 30-60cm long.
- Harvesting:
- First year: No harvesting.
- Second year: Only a few stalks.
- Established plants: Harvest from spring onwards, stalks should be between 30-60cm long.
The Dangers Of Rhubarb Foliage To Pets And Humans
While rhubarb stalks are a delightful addition to numerous dishes, it’s crucial to be aware of the potential dangers associated with the foliage. The leaves of rhubarb plants contain substances that are toxic to cats, dogs, horses, and people. Ingesting the leaves can lead to severe health complications.
To ensure the safety of pets and humans, it’s essential to keep them away from the foliage of rhubarb plants. Educate yourself and others about the risks and avoid using the leaves in culinary preparations. With proper precautions, you can enjoy the delicious rhubarb stalks without any harm.
Harvesting And Cooking Rhubarb: Tips And Timing
Harvesting rhubarb is an exciting time for any gardener or food enthusiast. To harvest rhubarb, simply pull and twist the stems off the plant. This gentle method ensures you don’t damage the crown and allows the plant to continue producing new stalks throughout the growing season.
Forced rhubarb, obtained through early harvesting methods, is ready from late winter to early spring. The stalks are shorter but have a sweeter taste compared to those harvested later in the season. The vibrant red stalks can be used in various ways, such as:
- Stewing with sugar
- Making crumbles
- Topping for porridge
- Making cordials and other refreshing drinks
It’s worth mentioning that rhubarb is best cooked shortly after being picked. However, if you have an abundance of rhubarb, you can freeze it raw to use in recipes later on.
Common Diseases And Management Of Rhubarb Plants
Like any garden plant, rhubarb is susceptible to various diseases that can affect its growth and productivity. Some common diseases that can impact rhubarb plants include honey fungus, crown rot, and viruses. Among these, crown rot is the most prevalent, leading to browning and softening of the crowns.
To manage diseases, it’s crucial to maintain soil fertility and overall plant health. Regularly mulching the soil around the plants with compost, manure, or leaf mould in autumn can provide essential nutrients and improve soil structure. Proper irrigation practices and careful monitoring of the plants can also help in detecting and managing diseases early on.
In case of any sign of disease, it’s advisable to dig up affected plants and relocate them to prevent the spread of infection. Flowering rhubarb can be managed by removing any flower stalks as soon as they appear, directing the plant’s energy towards producing healthier foliage and stalks.
Planting and propagating rhubarb requires careful attention to soil fertility, watering needs, and the potential dangers associated with the foliage. By following the recommended techniques, including forcing rhubarb for an early crop, you can enjoy the bountiful harvests and versatile uses of this delightful vegetable for years to come. Happy rhubarb growing!
Frequently Asked Questions
Can you grow rhubarb from cuttings?
While it is possible to grow rhubarb from cuttings, it is not as widely practiced as dividing rhubarb or growing from seed. Dividing rhubarb is the preferred method due to its higher success rate and faster results. However, if you are adventurous and want to try growing rhubarb from cuttings, it can be done with patience and care.
Can rhubarb grow from a piece of root?
Yes, rhubarb can indeed grow from a piece of root. When dividing mature plants, it is recommended to dig up the entire clump while dormant, typically between mid-autumn and early spring. By using a spade or an old kitchen knife, you can carefully slice the plant into several smaller sections, ensuring that each division has a portion of the rhizome (thickened root) and at least one growing point or bud. This allows each new section to develop into a new rhubarb plant, providing a means of propagation and expansion for your rhubarb garden.
How does rhubarb reproduce?
Rhubarb, known for its tart stalks used in culinary creations, follows a unique reproductive process. While it does produce seeds, they do not result in true offspring. Instead, rhubarb typically reproduces through a method called vegetative propagation, specifically by utilizing cuttings. During the winter, the visible parts of the plant wither away, while the rhizomes beneath the surface and the robust root system persist as the perennial components. By utilizing this method, rhubarb ensures its genetic and desirable traits are consistently maintained and propagated.
Is rhubarb easy to grow from seed?
Growing rhubarb from seed can be a rewarding yet slightly lengthier process compared to growing from crowns. Although it may require additional time and patience, cultivating rhubarb from seed remains an accessible endeavor, especially if you have ample space. While plants sprouting from seeds may take an extra year to establish themselves compared to mature crowns, their cost-effective nature makes them an enticing option. With enough room and willingness to wait, growing rhubarb from seed can offer a fruitful and budget-friendly experience.
