Rhubarb, a perennial plant known for its tart stalks and delicious pies, is a staple in many gardens. While it can be grown from seed, taking cuttings from established plants is a more reliable and efficient method for propagating rhubarb. This article will delve into the world of rhubarb propagation, exploring the best practices for taking cuttings and ensuring a high success rate.
Understanding Rhubarb Plant Anatomy
Before taking cuttings, it’s essential to understand the anatomy of a rhubarb plant. Rhubarb plants consist of a crown, which is the thick, underground stem that produces new growth. The crown is surrounded by a fibrous root system, and from it emerge the stalks, also known as petioles, which are the edible parts of the plant. To take successful cuttings, one must identify the right parts of the plant to use.
Identifying the Best Cutting Material
The best cutting material for rhubarb propagation is the crown itself, specifically the sections that have produced new growth. These sections are called “crown divisions” or “crowns.” Each division should have at least one “eye” or bud, which will produce new growth. Crown divisions with multiple eyes have a higher chance of success, as they can produce multiple new plants. It’s also crucial to choose divisions from healthy, disease-free plants to ensure the new plants will thrive.
Preparing the Plant for Cutting
Before taking cuttings, the rhubarb plant should be prepared to minimize stress and promote new growth. This involves allowing the plant to go dormant during the winter months, which helps the crown to recharge and produce new energy. In the early spring or late winter, when the plant is still dormant, the crowns can be lifted and divided. It’s essential to handle the crowns carefully to avoid damaging the delicate buds and roots.
Taking Cuttings from Rhubarb
Taking cuttings from rhubarb is a relatively straightforward process that requires some care and attention to detail. The following steps outline the best practices for taking and handling rhubarb cuttings:
To take a cutting, carefully lift the crown and identify the natural divisions between the buds. Using a sharp, clean knife or garden fork, gently separate the divisions, making sure each section has at least one eye. The divisions should be about 2-3 inches (5-7.5 cm) in diameter and have a similar number of eyes. It’s essential to handle the cuttings carefully to avoid damaging the buds or roots.
Handling and Storing Cuttings
After taking the cuttings, it’s crucial to handle and store them properly to maintain their viability. The cuttings should be kept moist but not waterlogged, as this can lead to rot and reduce the chances of successful propagation. The cuttings can be stored in a cool, dark place, such as a refrigerator or a cold frame, until they are ready to be planted.
Planting the Cuttings
When planting the cuttings, choose a location with full sun to partial shade and well-draining soil. Rhubarb prefers a slightly acidic to neutral soil pH, ranging from 5.5 to 6.5. Plant the cuttings about 2-3 inches (5-7.5 cm) deep, with the eyes facing upwards. Water the soil gently but thoroughly, and keep the soil consistently moist during the first growing season.
Post-Planting Care and Maintenance
After planting the cuttings, it’s essential to provide the right conditions for the new plants to establish themselves. This includes regular watering, fertilization, and mulching. Rhubarb plants require about 1 inch (2.5 cm) of water per week, either from rainfall or irrigation. A balanced fertilizer can be applied in the early growing season to promote healthy growth. Mulching around the plants helps retain moisture, suppress weeds, and regulate soil temperature.
Common Challenges and Solutions
While taking cuttings from rhubarb can be a successful propagation method, there are some common challenges to be aware of. One of the most significant challenges is root rot, which can occur if the soil is too wet or waterlogged. To avoid root rot, ensure the soil is well-draining and avoid overwatering. Another challenge is pests and diseases, such as slugs, snails, and fungal infections. Regularly inspect the plants, and use organic or integrated pest management methods to address any issues.

What is the best time to take cuttings for propagating rhubarb?
The best time to take cuttings for propagating rhubarb is during the dormant season, which typically occurs in late winter to early spring. This is the period when the plant is not actively growing, and the risk of transplant shock is minimized. Taking cuttings during this time allows the new plants to establish themselves before the growing season begins. It is essential to choose healthy, disease-free crowns with at least two eyes or buds, as these will produce the best results.
When taking cuttings, it is crucial to handle the crown carefully to avoid damaging the delicate buds or roots. Use a sharp, sterile knife or pruning saw to divide the crown, making sure each section has at least one eye or bud. Dip the cut ends in a rooting hormone powder or liquid to enhance the chances of successful propagation. Plant the cuttings in a well-draining potting mix, water thoroughly, and provide adequate moisture and light. With proper care, the new rhubarb plants should be ready to harvest within a year or two, depending on factors such as climate, soil quality, and watering conditions.
What are the different types of cuttings used for propagating rhubarb?
There are two main types of cuttings used for propagating rhubarb: crown cuttings and leaf bud cuttings. Crown cuttings involve dividing the entire rhubarb crown into sections, each containing at least one eye or bud. This method is the most common and reliable way to propagate rhubarb, as it allows for the rapid establishment of new plants. Leaf bud cuttings, on the other hand, involve removing individual leaf buds from the crown and planting them in a potting mix. This method can be more challenging, as the buds are sensitive to drying out and may not root as easily.
Both types of cuttings have their advantages and disadvantages. Crown cuttings are generally faster and more reliable, but they require a larger amount of plant material. Leaf bud cuttings, while more challenging, can be used to produce larger numbers of new plants from a single crown. Regardless of the method chosen, it is essential to handle the cuttings carefully and provide the right conditions for rooting and growth. With proper care and attention, both crown and leaf bud cuttings can be used to successfully propagate new rhubarb plants.
How do I prepare the soil for planting rhubarb cuttings?
Preparing the soil for planting rhubarb cuttings involves creating a well-draining, fertile mix that will support the healthy growth of the new plants. A mix of compost, peat moss, and perlite or vermiculite is ideal, as it provides good drainage and aeration while retaining moisture. The pH of the soil should be slightly acidic to neutral, ranging from 6.0 to 7.0. It is also essential to remove any weeds or debris from the soil, as these can compete with the new rhubarb plants for water and nutrients.
Before planting the cuttings, the soil should be moistened but not waterlogged. A layer of organic mulch, such as straw or bark chips, can be added to the surface to retain moisture and suppress weeds. Plant the cuttings at a depth of about 2-3 inches, making sure the eyes or buds are facing upwards. Water the soil gently but thoroughly, and provide adequate light and temperature conditions for rooting and growth. With proper soil preparation and care, the new rhubarb plants should establish themselves quickly and begin producing new growth within a few weeks.
What are the common challenges faced when propagating rhubarb from cuttings?
One of the common challenges faced when propagating rhubarb from cuttings is transplant shock, which can occur when the cuttings are not handled carefully or are exposed to extreme temperatures or moisture levels. Another challenge is the risk of disease, particularly fungal infections that can spread quickly in moist environments. Pests, such as slugs and snails, can also be a problem, as they can damage the delicate leaves and stems of the new plants.
To overcome these challenges, it is essential to handle the cuttings carefully and provide the right conditions for rooting and growth. This includes using sterile equipment, watering carefully, and providing adequate light and ventilation. It is also crucial to monitor the plants regularly for signs of disease or pests, and to take action promptly if any problems are detected. With proper care and attention, most challenges can be overcome, and the new rhubarb plants should thrive and produce healthy growth.
Can I propagate rhubarb using other methods, such as division or layering?
Yes, rhubarb can be propagated using other methods, such as division or layering. Division involves digging up the entire plant, separating the crown into sections, and replanting the sections in a new location. This method is similar to taking crown cuttings, but it involves moving larger sections of the plant. Layering, on the other hand, involves bending a stem down to the ground, securing it with a rock or stake, and allowing it to root before cutting it from the parent plant.
Both division and layering can be effective methods for propagating rhubarb, but they have some limitations. Division can be more challenging, as it requires digging up the entire plant and handling the crown carefully. Layering can be more time-consuming, as it requires waiting for the stem to root before cutting it from the parent plant. However, both methods can produce healthy new plants, and they can be used in conjunction with cuttings to increase the chances of successful propagation. With proper care and attention, rhubarb can be propagated using a variety of methods, each with its own advantages and disadvantages.
How long does it take for rhubarb cuttings to establish themselves and produce new growth?
The time it takes for rhubarb cuttings to establish themselves and produce new growth can vary depending on factors such as climate, soil quality, and watering conditions. Generally, it can take anywhere from 6-12 months for the cuttings to develop a strong root system and produce new leaves and stems. During this time, it is essential to provide the cuttings with adequate moisture, light, and nutrients, as well as to protect them from extreme temperatures and pests.
As the cuttings establish themselves, they should begin to produce new growth, including leaves, stems, and eventually, flowers. The first year after planting, the new rhubarb plants may not produce much edible stalk, but they should begin to produce more in the second and subsequent years. With proper care and attention, rhubarb plants can live for many years, producing delicious stalks and providing a bountiful harvest. By following the right propagation techniques and providing the right conditions, gardeners can enjoy a thriving and productive rhubarb patch for years to come.
