When selecting a rhubarb variety, keep in mind the desired taste, color, and climate compatibility. Talk to experts at your local nursery or garden center if you need help determining the best variety for your garden.

Preparing the Soil and Planting Site

Soil and Drainage Requirements

Rhubarb thrives in fertile, organically rich, well-worked, and well-drained soil. To prepare the soil, mix in aged compost or aged manure, or use a commercial organic planting mix. This enriches the soil with essential nutrients, as rhubarb plants are heavy feeders. Aim for a soil pH between 5.0 and 6.8 for optimal growth.

Well-drained soil is crucial to successful rhubarb growth, as the plants may rot if kept too wet. If your garden has heavy clay soil, consider constructing a raised bed for your rhubarb plants. This will help improve drainage and create a beneficial growing environment.

Selecting the Perfect Location

Choose a planting site for your rhubarb that has the following characteristics:

Light: Rhubarb grows best in full sun, but will also tolerate partial shade. Ensure the location receives ample sunlight to promote healthy growth.
Space: Each rhubarb plant needs sufficient room for its roots to expand. Plant your rhubarb about 3-4 feet apart to provide adequate space for root system development.

Proximity to other plants: Since rhubarb is a perennial vegetable, it’s important to select a location where it won’t be disturbed by the annual rotation of other vegetables in your garden.

In summary, to create the ideal planting site for rhubarb, choose a location with well-drained, fertile soil in a spot that receives full sun or partial shade. Adequate space between plants is necessary, and choosing a spot separate from your annual vegetable rotation will allow your rhubarb to thrive year after year.

Planting Rhubarb

Using Crowns

Rhubarb is typically grown from crowns, which are root divisions from established plants. This method speeds up the harvest, allowing gardeners to enjoy the fruits of their labor sooner. When planting rhubarb crowns, follow these steps:

Choose a sunny location with well-draining soil. Rhubarb thrives in full sun and does not tolerate sitting in water.
Space crowns approximately 2 to 4 feet apart in rows that are 3 to 4 feet apart. This spacing will give each plant enough room to grow and encourage a more productive harvest.
Dig holes deep enough to accommodate the crowns, around 4 inches deep, with the buds facing upwards.

Place the crowns into the holes and cover them with soil, ensuring the eyes are about 2 inches below the soil surface.
Water the newly planted crowns thoroughly to kickstart the growth process.

Growing Rhubarb from Seed

While it’s more common to use crowns, rhubarb can also be grown from seed:

Start seeds indoors in late winter or early spring, 6 to 8 weeks before the last expected frost in your growing zone.
Plant seeds in pots filled with a high-quality, well-draining potting mix.
Sow seeds approximately 1/4 inch deep in the soil and keep them moist and in a warm location.

Once seedlings have developed at least 2 true leaves, transplant them to larger pots to continue growing.
When the danger of frost has passed and seedlings are strong and healthy, transplant them outdoors, following the same spacing and planting depth guidelines as previously mentioned for crowns.

By following these planting techniques for both crowns and seeds, gardeners will have a solid foundation for growing healthy and productive rhubarb plants. Mid-summer is generally the best time to harvest the stalks, taking care not to disturb the roots to ensure future growth.

Caring for Rhubarb Plants

Watering and Moisture Requirements

Rhubarb plants require consistent moisture and well-drained soil to thrive. It’s essential to water the plants every time the soil starts to look dry during summer months. To help retain moisture and discourage weeds, mulch generously with a heavy layer of straw around the base of the plants.

Nutrient and Fertilization Needs

To ensure optimal growth, rhubarb plants need to be nourished with nutrients and organic matter. To provide essential nutrients, amend the soil with compost and well-rotted manure when planting rhubarb. Additionally, applying a suitable fertilizer during the growing period can improve the overall health of the plants.

Here are some fertilization tips for rhubarb plants:

Use organic matter such as hay and cow manure to nourish the plants and keep weeds at bay.
Leaf mulch or ramial wood chips can also be used as an alternative to hay and cow manure.
If using a commercial fertilizer, choose one that’s high in phosphorus and potassium to promote strong roots and abundant growth.

Controlling Pests and Diseases

Pests and diseases can affect the health of rhubarb plants if not managed properly. Common pests, such as rhubarb curculio, can damage leaves and stems. To protect the plants, follow these preventative measures:

Inspect plants regularly to detect any pests or diseases early.
Remove and dispose of any infected or damaged parts of the plant promptly.

Avoid the use of pesticides unless absolutely necessary, as they can harm beneficial insects.

By following these guidelines on water, nutrients, and pest management, rhubarb plants can be grown successfully and yield a bountiful harvest.

Harvesting Rhubarb

When and How to Harvest

Rhubarb stalks are ready to harvest when they are 7 to 15 inches long. The color of the stalks is not an indicator of ripeness, so it is not necessary to wait for them to turn red. You can harvest rhubarb from spring until mid-summer, but it’s best to stop harvesting after that to allow the plants to recuperate and store up energy to survive the winter.

To harvest rhubarb, use a sharp knife or shears to cut off stalks that are at least 10 inches (25 cm) or longer. Alternatively, you can gently pull the stalk while gently leaning it to one side until it breaks off from the plant. When harvesting, avoid eating rhubarb leaves as they contain poisonous concentrations of oxalic acid.

Storing and Preserving Your Rhubarb Harvest

Once you have harvested your rhubarb, proper storage is essential to maintain freshness and quality. Here are some ways to store and preserve your rhubarb harvest:

Refrigerator: Store fresh rhubarb stalks in the refrigerator by wrapping them in a damp paper towel and placing them in a plastic bag. They can last for up to 2 weeks if stored properly.

Freezer: To freeze rhubarb, first, wash and trim the stalks, then cut them into 1-inch pieces. You can either blanch the pieces for 1 minute in boiling water or leave them unblanched. Spread the pieces on a baking sheet and freeze until solid, then transfer them to airtight containers or freezer bags. Frozen rhubarb can last up to a year.
Canning: You can also preserve rhubarb by canning it. Prepare a simple syrup by combining equal parts water and sugar, then cook the rhubarb in the syrup until it’s tender. Fill sterilized jars with the rhubarb mixture and process using a water bath canner according to the manufacturer’s instructions.

By harvesting your rhubarb at the right time and using proper storage techniques, you can enjoy this versatile vegetable throughout the year.

Unique Rhubarb Growing Techniques

Rhubarb is a perennial crop that thrives in cooler climates such as Canada, requiring full sun exposure for optimal growth. In this section, we will discuss two unique techniques for growing rhubarb: Forcing Rhubarb and Growing Rhubarb in Pots.

Forcing Rhubarb

Forcing rhubarb is a technique used to promote early, tender stalks in established rhubarb plants. This is popular in regions with cooler temperatures.

Begin forcing rhubarb in late winter or early spring, when the soil temperature is still cool.
Select an established plant, ideally one that is at least three years old.
Before the leaves emerge, cover the crown with a forcing pot or container, like a large bucket or a specialized rhubarb forcer.

Insulate the container with straw, leaves, or another insulating material.
Check periodically for new growth. Harvest stalks when they are around a foot long by pulling gently upwards and twisting.

Forced rhubarb will produce tender and faster-growing stalks, but it is important to note that this technique can weaken the plant. Allow the plant to recover for a year or two before forcing it again.

Growing Rhubarb in Pots

Grow rhubarb in pots for flexibility and to maximize space utilization in your garden. Here’s how to grow rhubarb in pots effectively:

Choose a large, deep container (at least 20 inches in diameter and depth) with drainage holes to accommodate rhubarb’s extensive root system.
Fill the pot with a well-draining soil mix, amended with compost or aged manure to enrich the soil.

Plant the rhubarb crown, ensuring the top sits about 1–2 inches below the soil surface.
Water the pot regularly to keep the soil consistently moist but avoid over-watering, which can lead to root rot.

When growing rhubarb in pots, be mindful of temperature fluctuations, as pots can heat up quickly in the sun. In extremely hot weather, move the pot to a partially shaded area to protect the plant.

Remember, it is essential to give rhubarb plants time to establish before harvesting; typically, it is suggested to wait until the second or third year for the best quality stalks.
