Carefully selecting your rhubarb crown is the first step in ensuring a successful harvest. Understanding the different varieties and their characteristics will set you on the right path when learning how to plant rhubarb crowns.

Preparing the Planting Site

Before you even receive your crown, preparing the planting site is crucial. Rhubarb prefers a well-drained, fertile soil, and proper site preparation is key to its long-term health and productivity. The right location will determine how well your rhubarb thrives, after you learn how to plant rhubarb crowns.

Sunlight and Location

Rhubarb thrives in full sun, which means at least six hours of direct sunlight per day. However, in hotter climates, it can benefit from some afternoon shade. Choose a location that receives ample sunlight but is also somewhat protected from strong winds.

Soil Preparation

Rhubarb is a heavy feeder and requires rich, well-drained soil. Here’s how to prepare the soil:

Soil Test: Conduct a soil test to determine the pH level and nutrient content. Rhubarb prefers a slightly acidic soil with a pH between 6.0 and 6.8.
Clear the Area: Remove all weeds, rocks, and debris from the planting area.
Amend the Soil: Incorporate plenty of organic matter, such as compost, well-rotted manure, or leaf mold, into the soil. This improves drainage, fertility, and water retention. Add a generous amount, about 4-6 inches, and work it into the top 12 inches of soil.
Improve Drainage: Rhubarb does not tolerate waterlogged soil. If your soil is heavy clay, consider adding coarse sand or gravel to improve drainage. You can also plant rhubarb on a raised bed.

Proper soil preparation is an essential part of learning how to plant rhubarb crowns. Taking the time to amend the soil and choose the right location will provide your rhubarb plants with the best possible start.

Planting Your Rhubarb Crowns

Now, let’s get to the main event: planting your rhubarb crowns. This process is relatively straightforward, but following the correct steps is crucial for success. Knowing how to plant rhubarb crowns correctly ensures a healthy start for your plants.

Timing Is Key

The best time to plant rhubarb crowns is in early spring, as soon as the soil can be worked, or in the fall, before the ground freezes. Planting in the spring gives the plants a full growing season to establish themselves. Fall planting allows the roots to establish over the winter.

Step-by-Step Planting Guide

Here’s a step-by-step guide on how to plant rhubarb crowns:

Prepare the Crown: Inspect the crown and remove any dead or damaged roots. You can also trim the larger roots to about 6-8 inches long to encourage new growth.
Dig the Hole: Dig a hole that is wide enough to accommodate the crown, typically about 2-3 feet apart, and deep enough to plant the crown so that the top of the crown is about 2 inches below the soil surface.
Position the Crown: Place the crown in the hole with the buds facing upwards.
Backfill the Hole: Backfill the hole with the amended soil, gently patting it around the crown.
Water Thoroughly: Water the newly planted crown deeply to settle the soil and encourage root growth.
Mulch: Apply a layer of organic mulch, such as straw or wood chips, around the base of the plant, leaving a few inches of space around the crown itself. Mulch helps retain moisture, suppress weeds, and regulate soil temperature.

Spacing and Depth

Proper spacing and planting depth are critical for the health and productivity of your rhubarb plants. Plant crowns about 3-4 feet apart to allow for sufficient growth. The top of the crown should be buried about 2 inches below the soil surface. Planting too deep can lead to rotting, while planting too shallow can cause the crown to dry out.

Following these steps will ensure you know how to plant rhubarb crowns for the best results.

Caring for Your Rhubarb Plants

Once you know how to plant rhubarb crowns, ongoing care is essential to keep your plants healthy and productive. This includes watering, fertilizing, weeding, and protecting your plants from pests and diseases. Proper care will ensure a bountiful harvest for years to come.

Watering

Rhubarb requires consistent moisture, especially during dry spells. Water deeply and regularly, providing about 1-2 inches of water per week, especially during the growing season. Avoid overhead watering, which can promote fungal diseases. Water at the base of the plant.

Fertilizing

Rhubarb is a heavy feeder and benefits from regular fertilization. In early spring, apply a balanced fertilizer or a side dressing of compost or well-rotted manure. You can also fertilize again after harvesting in mid-summer. Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of stalk production.

Weeding

Keep the area around your rhubarb plants free of weeds. Weeds compete with rhubarb for nutrients, water, and sunlight. Mulching helps suppress weeds, but you may still need to hand-weed occasionally. Be careful not to damage the rhubarb crowns while weeding.

Pest and Disease Control

While rhubarb is relatively pest-free, it can be susceptible to a few problems:

Rhubarb Curculio: This insect can damage the stalks. Remove and destroy any affected stalks.
Aphids: These small insects can suck the sap from the leaves. Control them with insecticidal soap or neem oil.
Crown Rot: This fungal disease can be caused by overwatering or poor drainage. Ensure proper drainage and avoid overwatering.

Inspect your plants regularly for any signs of pests or diseases. Addressing problems early can prevent them from spreading and damaging your plants. Proper care is key to answering the question of how to plant rhubarb crowns successfully.

Harvesting Rhubarb

Harvesting rhubarb is a simple process, but it’s important to do it correctly to ensure the continued health and productivity of your plants. Knowing when and how to harvest is essential. It’s an exciting part of the process after learning how to plant rhubarb crowns.

When to Harvest

Do not harvest any rhubarb during the first year after planting to allow the plant to establish a strong root system. In the second year, you can harvest sparingly. After the second year, you can harvest more heavily. The harvest season typically begins in late spring or early summer and lasts for about 8-10 weeks.

How to Harvest

Harvest rhubarb stalks by grasping them near the base and twisting them gently, pulling them away from the crown. Avoid cutting the stalks, as this can leave stubs that may rot. Remove the leaves immediately after harvesting, as they contain high levels of oxalic acid and are not edible. Leave at least one-third of the stalks on the plant to ensure continued growth.

Harvesting Tips

Don’t Harvest Too Much: Avoid over-harvesting, as this can weaken the plant.
Harvest Regularly: Harvest stalks regularly to encourage new growth.
Stop Harvesting in Late Summer: Stop harvesting in late summer to allow the plant to store energy for the following year.

Harvesting your own rhubarb is a rewarding experience after learning how to plant rhubarb crowns and nurturing your plants. Enjoy the fruits (or stalks!) of your labor!

Common Problems and Solutions

Even with the best care, rhubarb plants can sometimes encounter problems. Understanding common issues and their solutions can help you maintain healthy, productive plants. Knowing how to troubleshoot is an important part of learning how to plant rhubarb crowns.
