How to Pollinate Rhubarb Plant:
Increase Your Yield

Updated: July 3, 2023

Rhubarb is a popular perennial plant known for its tart and tangy stalks that are used in various culinary creations. While rhubarb plants are capable of producing seeds and self-pollinating, manually pollinating them can significantly increase your yield. In this article, we will discuss the importance of pollination for rhubarb plants and provide you with step-by-step instructions on how to effectively pollinate your rhubarb plant.

The Importance of Pollination for Rhubarb Plants

Pollination is a crucial process for the reproduction and growth of plants. It involves transferring pollen from the male reproductive organs (stamen) to the female reproductive organs (pistil) of a flower. When it comes to rhubarb plants, proper pollination ensures the development of healthy seeds, which in turn results in better yields.

Rhubarb plants have both male and female flowers on separate stalks. However, they are typically dioecious, meaning that a single plant will have either all male flowers or all female flowers. Female flowers produce seeds, while male flowers produce pollen. Without pollination, the female flowers will not produce viable seeds, leading to reduced yields.

Identifying Male and Female Rhubarb Flowers

Before you can effectively pollinate your rhubarb plant, it is essential to identify the male and female flowers. Male flowers are smaller in size and have taller stalks compared to female flowers. They contain pollen-producing stamens surrounded by petals. On the other hand, female flowers are larger and have shorter stalks. They have a stigma at the center, which is responsible for receiving the pollen.

Steps to Pollinate Rhubarb Plants

Now that you know the importance of pollination and how to identify male and female rhubarb flowers, let’s dive into the step-by-step process of pollinating your rhubarb plant:

Step 1: Determine the Flowering Time

Rhubarb plants typically flower in late spring or early summer. It is crucial to monitor your plant and determine when the flowers begin to bloom. This will help you plan the pollination process accordingly.

Step 2: Identify the Female Flowers

Inspect your rhubarb plant for female flowers. These flowers will have a stigma at the center, which is often sticky and receptive to pollen. Once you have identified the female flowers, mark them with a small ribbon or string to make them easily distinguishable.

Step 3: Find a Male Flower

Locate a male flower on a separate rhubarb plant or a different stalk of the same plant. Ensure that the male flower has fully developed pollen-producing stamens. Gently touch the stamens to confirm if they release pollen. If they do, this indicates that the flower is ready for pollination.

Step 4: Transfer Pollen to Female Flowers

Take a small, clean brush or cotton swab and gently dab it onto the stamens of the male flower. This will collect the pollen on the brush or swab. Now carefully transfer the collected pollen onto the stigma of the female flower. Make sure to cover the entire stigma with pollen to ensure successful pollination.

Step 5: Repeat as Needed

Continue this process for each marked female flower on your rhubarb plant. If you have multiple male flowers available, you can use a different brush or swab for each flower to avoid cross-contamination.

Step 6: Provide Optimal Growing Conditions

After pollination, it is essential to provide optimal growing conditions for your rhubarb plant. Ensure that it receives adequate sunlight, water, and nutrients throughout its growing season. Regularly monitor its progress and provide any necessary care such as fertilization or pest control.

Conclusion

Pollinating your rhubarb plants can significantly increase your yield and ensure the production of healthy seeds. By following the step-by-step instructions provided in this article, you can effectively pollinate your rhubarb plant and enjoy a bountiful harvest. Remember to always monitor the flowering time, identify male and female flowers correctly, and transfer pollen from male to female flowers. With proper care and attention, your rhubarb plants will thrive and provide you with delicious stalks for years to come.
