Getting Started: Choosing Your Rhubarb and the Perfect Spot
Success in the garden always starts with two things: the right plant and the right place. Getting this part correct sets you up for a future filled with delicious, ruby-red stalks.
Picking a Rhubarb Variety
While you might just see “rhubarb” at the garden center, there are several wonderful varieties to choose from. They mainly differ in stalk color, size, and tartness.
- Victoria: A classic, reliable heirloom. It produces thick, green stalks with a blush of red and has a wonderfully balanced tart flavor. It’s a very vigorous grower.
- Canada Red or MacDonald: Known for its sweet flavor and brilliant, deep red stalks that hold their color when cooked. A fantastic choice for desserts.
- Glaskin’s Perpetual: An excellent variety if you’re eager for a harvest. It has lower oxalic acid levels, allowing for a longer harvesting season.
My personal advice? Don’t get too hung up on the variety as a beginner. Any healthy crown you find will likely bring you joy. They are all delicious!
The Ideal Location: Sun and Soil
Rhubarb isn’t overly demanding, but it does have preferences. Think of it as finding the perfect cozy corner for a long-term friend.
Sunlight: Aim for a spot that gets at least 6 hours of full sun per day. This sunlight fuels the big, leafy growth that, in turn, feeds the root system for next year’s stalks. It can tolerate a little partial shade, especially in very hot climates, but full sun is best.
Soil: This is where you can make the biggest difference. Rhubarb craves rich, well-draining soil. It absolutely hates “wet feet,” which can lead to crown rot. Before planting, amend your soil generously with well-rotted compost or manure. This provides the nutrients it needs and improves drainage. A slightly acidic to neutral pH (6.0 to 7.0) is perfect.
The Ultimate Rhubarb Planting Guide: From Crown to Creation
Planting rhubarb is a simple, satisfying task. You’re not just planting a vegetable; you’re establishing a perennial that could outlive you! Here’s our step-by-step rhubarb gardening tips guide for planting.
When to Plant
The best time to plant rhubarb crowns is in the early spring, just as the ground is workable and the crown is still dormant. You can also plant in the autumn after dormancy has begun, which gives it a head start on root development over the winter.
How to Plant Rhubarb Crowns
Follow these simple steps, and you’ll know exactly how to rhubarb gardening tips can be put into action.
- Prepare the Hole: Dig a wide, generous hole, about twice the width and depth of the crown itself. Remember, this plant will be here for 20+ years, so give it a great home!
- Amend the Soil: Backfill the hole with a 50/50 mix of your garden soil and high-quality compost or aged manure. This creates a nutrient-rich environment that rhubarb loves.
- Position the Crown: Place the rhubarb crown in the hole so that the very top of the growth bud (the pointy red nub) is just visible, about 1-2 inches below the soil surface. Planting too deep is a common mistake that can lead to rot.
- Backfill and Water: Gently fill the rest of the hole with your amended soil, firming it lightly around the crown. Water it in thoroughly to settle the soil and eliminate air pockets.
- Spacing: If you’re planting more than one, give them space! Allow at least 3 to 4 feet between plants. They grow into large, impressive specimens and need good air circulation.
Essential Rhubarb Gardening Tips for a Thriving Patch
Once your rhubarb is in the ground, its care is wonderfully straightforward. This section of our rhubarb gardening tips care guide covers the simple, ongoing tasks that ensure your plant thrives for years to come.
Watering Wisdom
Rhubarb’s large leaves lose a lot of moisture on hot days, so consistent watering is key, especially during its first year as it gets established. Water deeply once or twice a week during dry spells.
A good rule of thumb is to check the soil. If the top inch is dry, it’s time to water. Consistent moisture prevents the stalks from becoming tough and woody.
Feeding Your Plant
Rhubarb is a heavy feeder. It needs plenty of energy to produce those thick, juicy stalks. The best practice is to feed it once a year in the early spring, just as new growth begins to emerge.
Apply a balanced fertilizer (like a 10-10-10) around the base of the plant, or better yet, top-dress with a thick, 2-inch layer of rich compost or well-rotted manure. This is one of the most impactful rhubarb gardening tips best practices you can adopt.
The Magic of Mulch
Mulching is a gardener’s best friend, and rhubarb agrees! Applying a 2-3 inch layer of organic mulch (like straw, shredded leaves, or wood chips) around the base of the plant offers numerous benefits:
- It suppresses weeds that compete for nutrients.
- It helps retain soil moisture, reducing your watering duties.
- It breaks down over time, adding valuable organic matter to the soil.
Just be sure to keep the mulch from directly touching the crown of the plant to prevent moisture from getting trapped, which could lead to rot.
Harvesting Your Rhubarb: The Sweet Reward of Patience
Knowing when and how to harvest is crucial. Get it right, and you’ll enjoy a steady supply. Get it wrong, and you could weaken your plant.
The Most Important Rule: The Waiting Game
This is the hardest part for an eager gardener, but it’s non-negotiable. Do NOT harvest any stalks during the first year. Let the plant put all its energy into developing a strong, robust root system. This patience will be rewarded tenfold in the years to come.
In the second year, you can take a small harvest of just 2-3 stalks. From the third year onwards, you can harvest freely for about 8-10 weeks.
How to Harvest Rhubarb Stalks
Never cut rhubarb stalks. Instead, grasp the stalk firmly near its base and pull it outwards with a gentle twisting motion. It should pop right off the crown. This method causes less damage to the crown than cutting.
Only harvest stalks that are at least 10-12 inches long and have fully unfurled leaves. Leave at least one-third of the stalks on the plant at all times to ensure it continues to photosynthesize and store energy for next year. Stop harvesting by mid-summer to let the plant recover before winter.
And now for the most critical safety tip: Rhubarb leaves are poisonous. They contain high levels of oxalic acid. Once you’ve pulled a stalk, immediately trim the leaf off and discard it in your compost pile. Only the stalks are edible.
Common Problems with Rhubarb Gardening and How to Solve Them
Even the toughest plants can run into trouble. Luckily, most common problems with rhubarb gardening tips can be easily managed if you know what to look for.
Crown Rot
This is the most serious issue for rhubarb. It’s a fungal disease caused by overly wet conditions. The base of the stalks will turn black and mushy, and the entire crown can rot away.
- Prevention: The best cure is prevention! Plant in well-draining soil, avoid overwatering, and ensure good air circulation.
- Solution: If you spot it early, you may be able to save the plant by digging it up, cutting away any soft, rotted portions with a clean knife, and replanting it in a better-draining location.
Bolting (Flowering)
Sometimes, a large, dramatic flower stalk will shoot up from the center of the plant. This is called bolting. It’s often triggered by stress, such as drought, extreme heat, or the plant being too mature. While the flowers are interesting, they divert energy from stalk production.
Solution: As soon as you see a flower stalk forming, cut it off at the base. This redirects the plant’s energy back into making more delicious stalks for you.
Pests: Rhubarb Curculio
Rhubarb is wonderfully pest-resistant, but you might occasionally spot the Rhubarb Curculio, a rusty-looking beetle that drills holes in the stalks. The damage is mostly cosmetic.
Solution: The best approach is to simply hand-pick them off and drop them in a bucket of soapy water. No pesticides needed!
Sustainable and Eco-Friendly Rhubarb Gardening Tips
Growing rhubarb is inherently sustainable, but you can enhance its eco-friendly credentials. Adopting these sustainable rhubarb gardening tips helps you create a healthier garden ecosystem.
One of the key benefits of rhubarb gardening tips is how well it fits into a low-impact garden. It’s a perennial, meaning less soil disturbance, and its needs are simple.
- Compost Everything: Use your own homemade compost to feed your rhubarb. Add the trimmed (and toxic) leaves right back into your compost bin—the oxalic acid breaks down safely during the composting process.
- Water Wisely: Use a rain barrel to collect water for your garden. Watering deeply but less frequently encourages deep root growth and conserves water.
- Companion Planting: Plant members of the onion family (garlic, chives) or brassicas (broccoli, cabbage) nearby. They are thought to help deter common garden pests, creating a natural, protective barrier.
These eco-friendly rhubarb gardening tips ensure your patch is not just productive but also a positive part of your local environment.
Frequently Asked Questions About Rhubarb Gardening Tips
Why are my rhubarb stalks thin and spindly?
This is usually a sign of three things: the plant is too young (give it time!), it needs more food, or it’s overcrowded. If the plant is over three years old, feed it with a rich layer of compost in the spring. If the clump is very old and dense, consider digging it up and dividing it to give it new life.
Do I need to do anything for my rhubarb in the winter?
Rhubarb is very cold-hardy and needs a period of dormancy below 40°F (4°C) to produce stalks. After the first hard frost kills the top growth, you can simply cut the dead leaves and stems back to the ground. Applying a thick layer of mulch after the ground freezes can help protect the crown from extreme freeze-thaw cycles.
How often should I divide my rhubarb plant?
Every 5-10 years, you may notice your rhubarb patch becoming less productive with smaller stalks. This is a sign it’s time to divide the crown! In early spring, dig up the entire root ball and use a sharp spade to divide it into sections, ensuring each piece has at least one or two growth buds. Replant them, and you’ve just multiplied your rhubarb patch for free!
