Rhubarb Plant Seeds:
Guide to Storing, Sowing and Germination

Rhubarb is a popular perennial vegetable known for its tart taste and vibrant red stalks. Growing rhubarb from seeds can be a rewarding experience for gardeners looking to enjoy this versatile plant in their own backyard. This article will provide a comprehensive guide on storing, sowing, and germinating rhubarb plant seeds.

Storing Rhubarb Plant Seeds

Before we delve into sowing and germination, it is essential to understand how to properly store rhubarb plant seeds. Rhubarb seeds are relatively easy to save, making it convenient for gardeners who want to propagate their plants or share seeds with others.

To collect rhubarb seeds, allow the plant to flower and go to seed. The flowers will eventually produce seed pods that resemble small brown paper capsules. It is important to wait until these pods turn dry and brittle before harvesting the seeds. Once the seed pods are dry, gently break them open and collect the small black seeds inside.

To store rhubarb plant seeds, place them in a dry container such as a glass jar or an envelope. Ensure that the storage container is airtight to prevent moisture from damaging the seeds. Label the container with the variety and date of collection for easy reference later on. Store the container in a cool, dark place like a refrigerator or a cellar until you are ready to sow.

Sowing Rhubarb Plant Seeds

When it comes to sowing rhubarb plant seeds, timing is crucial. Rhubarb is a cool-season vegetable that thrives in temperatures between 40°F (4°C) and 75°F (24°C). It is best to start sowing indoors 8-10 weeks before the last expected frost date in your area.

To begin sowing, fill seed trays or small pots with a well-draining seed starting mix. Moisten the soil before sowing the seeds to ensure proper germination. Sow the rhubarb seeds on the surface of the soil, spacing them about an inch apart. Lightly press the seeds into the soil, but avoid covering them entirely as they need light to germinate.

After sowing, mist the soil gently with water to provide moisture without disturbing the seeds. Cover the seed trays or pots with a plastic dome or a plastic wrap to create a greenhouse effect and retain humidity. Place the containers in a warm location, ideally around 68°F (20°C), and ensure they receive indirect sunlight.

Germinating Rhubarb Plant Seeds

Rhubarb plant seeds typically take around 2-3 weeks to germinate. During this time, it is important to monitor the moisture levels in the soil to prevent it from drying out or becoming waterlogged. Keep the soil consistently moist but not saturated by misting it regularly or using a spray bottle.

Once the rhubarb plant seeds have germinated, remove the plastic dome or wrap to allow for proper air circulation. Move the containers to a well-lit area, such as a sunny windowsill or under grow lights, to provide sufficient light for healthy seedling growth.

As the seedlings continue to grow, thin them out by removing weaker or overcrowded plants. This will allow the remaining seedlings to have enough space and resources to develop into strong and robust plants. Transplant the thinned-out seedlings into individual pots once they have grown two sets of true leaves.

Transplanting Rhubarb Seedlings

When transplanting rhubarb seedlings outdoors, choose a sunny location with well-drained soil. Prepare the planting area by loosening the soil and incorporating organic matter such as compost or aged manure.

Dig a hole that is wide and deep enough to accommodate the root system of each seedling. Place the seedling in the hole, ensuring that the crown is level with or slightly above the soil surface. Backfill the hole with soil, gently firming it around the roots.

Space the transplanted seedlings 3-4 feet apart to allow for their large size at maturity. Water the newly transplanted seedlings thoroughly, and continue to provide regular water throughout their growing season.

Conclusion

Growing rhubarb from seeds can be a satisfying and rewarding experience for any gardener. By properly storing, sowing, and germinating rhubarb plant seeds, you can enjoy a bountiful harvest of this tart and versatile vegetable in your own backyard. Remember to provide appropriate care and maintenance to your rhubarb plants, and soon enough, you will be enjoying delicious rhubarb pies, sauces, and desserts straight from your garden.
