Understanding Bare-Root Rhubarb

What is Bare-Root

Bare-root rhubarb plants are dormant, with no soil around their roots during storage and transportation. They are lightweight and easy to handle, making them convenient for planting.

Planting bare-root rhubarb offers several benefits, including cost-effectiveness due to lower shipping expenses and faster establishment in the garden compared to potted plants.

Upon receiving bare-root rhubarb, it is crucial to handle them with care. Ensure the roots remain moist before planting, and trim any damaged or excessively long roots for optimal growth.

Importance for Planting

Choosing the right planting location for rhubarb is crucial as they thrive in well-draining soil with a pH level between 5.0 and 6.8. Select a site with full sun exposure for at least six hours daily.

Sunlight plays a vital role in the growth of rhubarb, aiding in photosynthesis and ensuring healthy leaf development. Lack of sunlight can lead to leggy growth and reduced yield.

Providing adequate space between rhubarb plants and other vegetation is essential for proper air circulation, preventing diseases like powdery mildew. Maintain a distance of about 3-4 feet between each plant.

Preparing for Planting

Essential Requirements

To ensure successful gardening of rhubarb, gardeners must focus on the soil conditions. The soil should be well-draining and rich in nutrients to support healthy plant growth. Testing the soil pH is crucial, with rhubarb plants thriving in slightly acidic to neutral soils. Conducting a soil test helps determine the current pH levels and any necessary amendments.

When selecting cultivars of rhubarb, gardeners have various options with unique characteristics. Different cultivars offer varying flavors and colors, catering to diverse preferences. It's essential to choose cultivars that are well-suited to your specific climate and growing conditions to ensure optimal growth.

Choosing the Best Cultivars

Understanding the nuances of different rhubarb cultivars is key to selecting the most suitable option for your home garden. Some cultivars may be more resilient to diseases like Fusarium wilt, ensuring a healthier plant in the long run. Consider factors such as taste preferences, color variations, and yield potential when choosing a cultivar.

For ideal site conditions, gardeners should prioritize factors like soil drainage and sunlight exposure. Rhubarb plants require well-drained soil to prevent issues like root rot. Adequate sunlight is crucial for photosynthesis and overall plant health. Proper spacing between plants allows for sufficient air circulation, reducing the risk of diseases.

Ideal Site Conditions

When preparing to plant rhubarb roots, ensure the selected site meets all necessary criteria for successful growth. Optimal soil drainage prevents waterlogging and promotes healthy root development. Assessing sunlight exposure is vital; rhubarb thrives in full sun but can tolerate partial shade. Adequate spacing between plants prevents overcrowding and competition for nutrients.

The Planting Process

Step-by-Step Guide

To plant a rhubarb root successfully, start by selecting a healthy bare-root rhubarb plant. Dig a large hole that can accommodate the spread roots comfortably. Position the rhubarb root in the hole with the vegetative growth buds facing upwards. Ensure the crown sits at ground level to promote healthy growth.

Remember to water the newly planted rhubarb root thoroughly to aid in production of new roots. After planting, gently press down on the soil around the plant to prevent air pockets and ensure proper soil compaction. This step helps support the plant's stability and promotes optimal growth.

Dividing and Propagating

Dividing and propagating rhubarb plants is essential for maintaining their productivity. To divide an established rhubarb plant, carefully dig up the mature plant during early spring or late fall. Use a sharp knife to separate sections of the crown that have both roots and buds attached. Replant these divisions in a new location for continued growth.

By dividing rhubarb plants every 4-5 years, you can rejuvenate older plants and encourage new vegetative growth. This process also helps prevent overcrowding, which can lead to reduced yields and smaller stalks over time.

Preventing Frost Damage

Protecting your rhubarb plants from frost is crucial for their long-term health and growth. During frost-prone periods, cover your plants with straw or mulch to insulate them from freezing temperatures. Alternatively, use frost blankets or row covers to shield your plants from extreme cold.

Frost poses a significant risk to rhubarb plants as it can damage tender shoots and leaves, hindering their ability to photosynthesize effectively. By taking proactive measures such as covering and insulating your plants, you can safeguard them against potential frost damage.

Aftercare for Rhubarb

Proper Care Steps

Rhubarb requires proper care to thrive, ensuring a bountiful harvest. Begin by maintaining nutrient levels through regular feeding. Adequate feeding during the growing season is crucial for robust plant growth. Regular maintenance is essential for healthy and productive rhubarb plants.

Fertilizing Your Plant

When it comes to fertilizing rhubarb, it's important to follow best practices. Choose suitable fertilizers rich in nutrients vital for rhubarb growth. Timing and frequency are key factors in ensuring maximum productivity of your plants.

Managing Pests

Pests can pose a threat to your rhubarb plants, impacting their health and yield. Be vigilant in identifying common pests that target rhubarb. Implement natural or chemical pest management strategies based on the severity of the infestation. Promptly address any signs of pest presence to safeguard your plants.

Harvesting and Storing

When to Harvest

Rhubarb harvests should be done in the second or third year after planting. Organic matter helps growth. Mature stalks are thick and firm, with vibrant colors. Proper harvesting ensures plant health and longevity.

Storing Tips

For storing rhubarb, trim leaves and store stalks in a plastic bag in the fridge. Freezing preserves freshness. To extend shelf life, blanch rhubarb before freezing or canning. Enjoy rhubarb year-round in various dishes.


You now have a solid grasp of how to plant and care for rhubarb, from understanding bare-root rhubarb to harvesting and storing your crop. By following the steps outlined, you are on your way to growing a thriving rhubarb patch in your garden. Remember to prepare the soil well, provide adequate aftercare, and enjoy the fruits of your labor come harvest time.
