How to Grow Thick Rhubarb Stalks

Rhubarb, with its tart and tangy flavor, is a popular addition to pies, jams, and other delicious desserts. To enjoy a bountiful harvest of thick and succulent rhubarb stalks, it’s important to provide the right growing conditions and care. In this article, we will guide you through the process of growing thick rhubarb stalks that will leave your taste buds craving for more.

1. Choose the Right Variety: Select a rhubarb variety that is known for producing thick stalks, such as ‘Victoria’, ‘Canada Red’, or ‘Cherry Red’. These varieties are renowned for their robust growth and juicy stems.

2. Find the Perfect Spot: Rhubarb thrives in full sun, so choose a location in your garden that receives at least 6-8 hours of direct sunlight each day. Ensure the soil is well-drained and rich in organic matter.

3. Prepare the Soil: Rhubarb prefers slightly acidic soil with a pH between 6.0 and 6.8. Before planting, amend the soil with well-rotted compost or aged manure to improve its fertility and drainage.

4. Planting Rhubarb: Rhubarb is typically planted as crowns, which are small sections of the plant’s root system. Dig a hole that is wide and deep enough to accommodate the crown. Place the crown in the hole, making sure the bud is facing upwards, and cover it with soil. Space the crowns at least 3 feet apart to allow for proper growth.

5. Watering: Rhubarb requires regular watering, especially during dry spells. Keep the soil consistently moist, but avoid overwatering, which can lead to root rot. A layer of organic mulch around the plants can help retain moisture in the soil.

6. Fertilizing: Apply a balanced organic fertilizer, such as compost or well-rotted manure, in early spring and again in late summer. Avoid high nitrogen fertilizers, as they can promote leafy growth at the expense of stalk development.

7. Weed Control: Keep the area around your rhubarb plants free from weeds. Regular weeding will prevent competition for nutrients and ensure that your plants grow vigorously.

8. Thinning: As your rhubarb plants mature, thin them out by removing any weak or spindly stalks. This will allow the remaining stalks to grow thicker and stronger.

9. Harvesting: Rhubarb can be harvested in its second year after planting. Wait until the stalks are at least 10-12 inches long before cutting them. To harvest, firmly grasp the stalk near the base and give it a gentle twist or pull. Avoid cutting the stalks, as this can leave behind a stub that may become vulnerable to diseases.

10. Division: Rhubarb plants benefit from division every 4-5 years to maintain their vigor. Dig up the crown and carefully divide it into sections, making sure each section has at least one strong bud. Replant the divisions in prepared soil, following the same planting instructions as before.

Now, let’s address some common questions about growing thick rhubarb stalks:

Q1. Can I grow rhubarb in containers?
A1. Yes, rhubarb can be grown in large containers as long as they provide enough space for the plant’s roots to grow. Ensure the container has drainage holes and use a well-draining potting mix.

Q2. Why are my rhubarb stalks thin and weak?
A2. Thin and weak stalks can be a result of insufficient sunlight, poor soil fertility, or overcrowding. Make sure your rhubarb plants receive adequate sunlight, amend the soil with organic matter, and thin out weaker stalks.

Q3. Should I remove the flower stalks from my rhubarb plants?
A3. Yes, it is recommended to remove flower stalks as soon as they appear. Allowing the plant to flower can divert energy from stalk production, resulting in thinner stems.

Q4. Can I harvest rhubarb in the first year?
A4. It is generally advised to wait until the second year to harvest rhubarb, as this allows the plant to establish a strong root system. However, if your rhubarb plant is exceptionally robust, you may harvest a few stalks in the first year.

Q5. How do I protect my rhubarb from pests?
A5. Rhubarb is relatively pest-resistant, but you may encounter issues with snails, slugs, or aphids. Use organic pest control methods, such as handpicking or applying natural repellents, to keep these pests at bay.

Q6. Can I grow rhubarb from seeds?
A6. While it is possible to grow rhubarb from seeds, it is a time-consuming process, and the resulting plants may not exhibit the same desirable traits as the parent plant. It is best to propagate rhubarb through crown division or purchase established crowns.

Q7. Should I cut back the leaves of my rhubarb plant?
A7. It is not necessary to cut back the leaves of your rhubarb plant unless they become diseased or damaged. The leaves provide nourishment to the plant, aiding in stalk development.

Q8. Can I grow rhubarb in a hot climate?
A8. Rhubarb is best suited to cooler climates and may struggle in hot regions. If you live in a hot climate, try planting rhubarb in a partially shaded area and ensure adequate soil moisture.

Q9. How long does it take for rhubarb to reach maturity?
A9. Rhubarb plants typically take 2-3 years to reach full maturity. During this time, they establish a strong root system and develop thick stalks.

Q10. Can I harvest rhubarb in the fall?
A10. Rhubarb is typically harvested in the spring and early summer. Harvesting in the fall can weaken the plant, as it needs time to store energy for the next growing season.

Q11. Can I transplant rhubarb?
A11. While it is possible to transplant rhubarb, it is best done in early spring or late fall when the plant is dormant. Take care not to damage the roots during the transplant process.

Q12. How do I prevent rhubarb stalks from becoming woody?
A12. Regular harvesting and removing any flower stalks can help prevent rhubarb stalks from becoming woody. Providing adequate water and nutrients to the plant also contributes to tender stalks.

Q13. Can I freeze rhubarb for later use?
A13. Yes, rhubarb can be frozen to preserve its freshness. Simply wash, trim, and chop the stalks into desired pieces before freezing. It can be used in pies, jams, and other recipes straight from the freezer.

By following these guidelines and addressing common questions, you can successfully grow thick and delicious rhubarb stalks that will elevate your culinary creations. Enjoy the process and savor the rewards of your homegrown rhubarb!
