What To Know
- Cut the stalks at the base, leaving a few inches of the stalk attached to the crown.
- Rhubarb is incredibly versatile and can be used in a wide range of recipes, from classic pies and crumbles to jams, sauces, and even cocktails.
- In colder climates, you can protect your rhubarb from frost by covering the crown with a layer of mulch.
Rhubarb, with its vibrant stalks and tangy flavor, is a beloved spring ingredient. But before you can enjoy those delicious pies and crumbles, you need to know how to plant rhubarb crowns. This guide will walk you through the process, from choosing the right crown to ensuring a successful harvest.
Understanding Rhubarb Crowns
Rhubarb is a perennial vegetable, meaning it comes back year after year. The part we eat is actually the petiole, the stalk that supports the leaves. The crown is the underground part of the plant, containing the roots and buds that will produce new stalks. When planting rhubarb, you’re essentially planting a piece of the root system, which will develop into a full plant.
Choosing the Right Rhubarb Crown
The quality of your crown directly impacts the success of your planting. Here’s what to look for:
- Healthy Appearance: The crown should be firm and free from any signs of rot, disease, or insect damage.
- Size: Aim for a crown that’s at least 2 inches in diameter and has several healthy buds.
- Variety: Consider the different varieties available. Some, like ‘Victoria’ and ‘Crimson Red,’ are known for their flavor and productivity.
Preparing the Planting Site
Rhubarb thrives in well-drained, fertile soil. Here’s how to prepare your planting site:
- Location: Choose a sunny spot that receives at least 6 hours of direct sunlight daily.
- Soil: Test your soil’s pH level. Rhubarb prefers slightly acidic soil (pH 6.0-6.5). Amend the soil with compost or aged manure if necessary.
- Space: Allow ample space between crowns. Plant them 3-4 feet apart to prevent overcrowding.
Planting Your Rhubarb Crowns
Once your planting site is ready, follow these steps to plant your rhubarb crowns:
1. Dig a Hole: Dig a hole that’s about 12 inches deep and wide enough to accommodate the crown’s roots comfortably.
2. Position the Crown: Place the crown in the hole with the buds facing upwards.
3. Backfill the Hole: Gently backfill the hole with soil, ensuring the crown is covered and the buds are at or slightly above soil level.
4. Water Thoroughly: Water the newly planted crown deeply to settle the soil around the roots.
Caring for Your Rhubarb
After planting, consistent care is crucial for healthy growth:
- Watering: Water your rhubarb regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
- Fertilizing: Feed your rhubarb with a balanced fertilizer in early spring before new growth emerges.
- Mulching: Apply a layer of organic mulch around the crown to retain moisture, suppress weeds, and regulate soil temperature.
- Pest and Disease Control: Monitor for common pests and diseases and address any issues promptly.
Harvesting Your Rhubarb
Rhubarb is typically ready for harvest in the spring, about a year after planting. Here’s how to harvest:
- Harvesting Time: Wait until the stalks are about 12-18 inches tall and have a vibrant color.
- Harvesting Method: Cut the stalks at the base, leaving a few inches of the stalk attached to the crown.
- Harvesting Frequency: Don’t harvest all the stalks at once. Leave some stalks to ensure the plant has enough energy to produce new growth.
Enjoying Your Rhubarb Harvest
Now that you’ve successfully grown your own rhubarb, it’s time to enjoy the fruits of your labor. Rhubarb is incredibly versatile and can be used in a wide range of recipes, from classic pies and crumbles to jams, sauces, and even cocktails.
Beyond the Harvest: Keeping Your Rhubarb Thriving
Rhubarb is a long-lived plant that can produce for many years. Here are some tips for ensuring your rhubarb continues to thrive:
- Division: Every few years, you can divide your rhubarb plants to create new plants. This helps to keep the plants healthy and productive.
- Renewal: In the fall, cut back the stalks and leaves to encourage new growth in the spring.
- Winter Protection: In colder climates, you can protect your rhubarb from frost by covering the crown with a layer of mulch.
The End of the Journey: A Farewell to Your Rhubarb Garden
As your rhubarb plants mature and provide you with delicious harvests year after year, remember that their journey is not solely about the deliciousness they offer. It’s about the connection you build with nature, the satisfaction of nurturing life, and the joy of enjoying the fruits of your labor.
What You Need to Know

Q: Can I plant rhubarb in a container?
A: Yes, you can plant rhubarb in a large container, but it may not produce as much as a plant grown in the ground. Choose a container that’s at least 18 inches wide and deep.
Q: When should I fertilize my rhubarb?
A: Fertilize your rhubarb in early spring before new growth emerges. Use a balanced fertilizer, such as 10-10-10.
Q: What are some common pests and diseases that affect rhubarb?
A: Common pests include aphids, leafhoppers, and spider mites. Common diseases include crown rot, rust, and leaf spot. Monitor your plants regularly and address any issues promptly.
Q: Can I eat the leaves of rhubarb?
A: No, rhubarb leaves contain oxalic acid, which is toxic to humans. Only eat the stalks.
