Did You Know?
1. Rhubarb stalks contain poisonous leaves: While the stalks of rhubarb are safe to consume, the leaves contain oxalic acid, which can be toxic if ingested in large quantities. So, make sure to never eat the leaves of rhubarb plants!
2. Rhubarb is a member of the buckwheat family: Despite its resemblance to celery or red stems, rhubarb actually belongs to the same family as buckwheat plants. This makes it more closely related to grains than to other fruits or vegetables.
3. Rhubarb can be used to make natural hair dye: The deep red color of rhubarb stems makes them useful for creating a natural hair dye. By boiling the stalks and using the resulting liquid as a rinse, some people have achieved a temporary reddish tint to their hair.
4. Rhubarb was once used as a medicinal plant: Traditionally, rhubarb was used in Chinese medicine as a laxative and for treating digestive problems. It was highly valued for its medicinal properties and only later gained popularity as a culinary ingredient.
5. The largest rhubarb leaf ever recorded was 2.5 meters (8.2 feet) wide: While the leaves of rhubarb plants are not suitable for consumption, they can grow to remarkable sizes. The largest recorded rhubarb leaf was documented to be a staggering 2.5 meters wide, making it larger than most humans!
Growing Rhubarb From Stalks: Challenges And Solutions
Growing rhubarb from a stalk can present several challenges, mainly because the cut stalk has a hard time retaining moisture. Rhubarb is known to dry out quickly after harvest, unless proper measures are taken to prevent this. One solution to retain moisture is to keep the cut stalk submerged in water or wrapped in plastic. This helps to slow down the drying process and increase the chances of successful growth.
However, the easiest and most reliable way to grow a new rhubarb plant is by planting a section taken from the root crown of an existing plant. This method ensures that the new plant already has an established root system, making it more resistant to moisture loss and better equipped to thrive.
To successfully grow rhubarb from a root crown section, it is crucial to prepare the soil in autumn before planting in spring. Select a spot with well-drained soil and full sunlight, and remove any weeds that may compete with the young rhubarb plant for nutrients. Adding compost and manure to the soil helps improve its fertility and provides essential nutrients for the growing plant.
In the spring, work in fertilizer and plant the crown divisions in two-inch-deep holes, with a spacing of three feet apart. This promotes healthy growth and allows sufficient space for the rhubarb plants to mature. Watering the rhubarb plants once a week during the growing season, ensuring the soil is thoroughly soaked to a depth of at least one inch, is essential for their overall health and productivity.
It is important to note that it is recommended to wait until the second year to harvest any rhubarb stalks. This allows the plants to grow strong roots, ensuring their long-term viability and maximum yield.
Propagating Rhubarb Through Division And Cuttings
If you wish to propagate rhubarb, division is the most successful and quick method. When dividing the plant, select sections with buds or tips and plant them at or just above the soil level to prevent crown rot, a common issue during the planting process.
Growing rhubarb from cuttings is less common but can be successful with reduced leaf area and daily water changes. Careful attention is required to prevent the cuttings from drying out.
Growing Rhubarb From Seeds: Tips And Considerations
Growing Rhubarb from Seeds
Growing rhubarb from seeds can be a viable option if obtaining crown divisions is not possible. However, it is important to consider that rhubarb seeds are unpredictable and may not necessarily produce the exact variety advertised. Therefore, it is recommended to purchase seeds from a reputable source to increase the chances of success.
To improve the seed germination process, soak the seeds in water for 1-2 hours before planting. This helps speed up the germination process and enhances the chances of successful growth.
Plant the rhubarb seeds in March or April when the soil temperature reaches at least 50 degrees Fahrenheit. Plant the seeds one inch deep in soil that has been raked to a fine texture and blended with fertilizer. As the seedlings start to grow, thin them to a spacing of 6 inches apart when they reach about 2 inches tall. This allows the remaining seedlings to have enough space to develop fully.
Note: Growing rhubarb from seeds takes longer and requires three years of growth before a light harvest can be taken. However, with proper care and patience, this method can yield healthy and productive rhubarb plants.
- Soak the seeds in water for 1-2 hours
- Plant the rhubarb seeds in March or April
- Plant the seeds one inch deep
- Thin the seedlings to a spacing of 6 inches apart
Cultivating Rhubarb In Containers: Guidelines And Recommendations
Growing rhubarb in containers is an excellent option when consistent direct sunlight is not available. To cultivate rhubarb successfully in a container, it is important to choose a pot or a container with a depth of at least 20 inches and a 10-gallon capacity. This provides sufficient space for the mature rhubarb plant’s extensive root system.
Preparing the soil for container planting involves blending potting soil with manure or compost. This helps create a fertile growing environment for the rhubarb plant, ensuring it receives the necessary nutrients for healthy growth.
When planting in containers, it is recommended to add either crown divisions or seedlings at any time except during the summer growing season. Due to the large size of rhubarb plants, it is advisable to limit one plant per container to avoid overcrowding.
Watering is essential for container-grown rhubarb plants. Immediately after planting, water the plant thoroughly, and then water the plants once or twice a week, ensuring the soil remains consistently moist but not waterlogged.
- Choose a container with at least 20 inches depth and a 10-gallon capacity
- Blend potting soil with manure or compost for a fertile growing environment
- Add crown divisions or seedlings, except during summer growth season
- Limit one plant per container to avoid overcrowding
- Water thoroughly after planting and then water once or twice a week, keeping soil consistently moist but not waterlogged.
Harvesting And Maintaining Rhubarb Plants For Optimal Growth
Harvesting rhubarb requires careful attention to ensure the plant’s vitality and productivity. It is crucial not to harvest any rhubarb stalks during the first year to allow the roots to establish properly. This patience in the initial stage of growth will result in stronger plants in the long run.
When the time for harvest arrives, it is important to use the twist and pull method rather than cutting the stalks with a knife. This helps prevent damage to the plant and allows for regrowth in the following seasons.
Rhubarb stalks are ready for harvest when they reach their full length, typically ranging from one to two feet long. However, it is advisable not to harvest more than one-third of the plant’s stalks at a time. This ensures that the plant can continue to thrive and produce a bountiful harvest in subsequent years.
To maintain the health of the rhubarb plant, it is essential to remove the toxic leaves immediately after harvesting. These leaves contain high levels of oxalic acid, which can be harmful if consumed. Additionally, removing any flowers that appear on the plant helps redirect the plant’s energy towards growing stalks rather than producing seeds. However, it is worth mentioning that rhubarb flowers can be used in flower arrangements and do not render the stalks poisonous.
growing rhubarb requires specific techniques and considerations for successful growth. Whether you choose to propagate through stalks, division, or seeds, proper soil preparation, watering, and care are crucial for optimal growth. With patience and attention to detail, you can enjoy a thriving rhubarb harvest year after year.

Frequently Asked Questions
Can you plant rhubarb from stalks?
Yes, it is possible to grow rhubarb from stalks. Rhubarb stalks can be planted to produce new plants, although this method may not be as reliable as using seeds or crowns. The stalks should be selected from healthy plants and cut into sections that are about 10 to 12 inches long. These sections can then be planted in a prepared soil bed, ensuring that the stalks are placed vertically with about 2 to 3 inches of the stalk above the soil surface. With proper care and patience, these planted stalks have the potential to develop into new rhubarb plants, allowing for a fresh harvest in the following years.
Can you plant rhubarb cuttings?
Yes, it is possible to plant rhubarb cuttings for propagating more plants.
