When To Plant Rhubarb In Ohio?

Rhubarb is a hardy perennial vegetable that thrives in cool climates and is widely grown in gardens across Ohio. If you are planning to grow rhubarb in your garden, it is essential to know the right time to plant it. Planting rhubarb at the right time is crucial for ensuring a successful harvest.

When Is The Best Time To Plant Rhubarb In Ohio?

The best time to plant rhubarb in Ohio is during early spring, typically from late March to early April. At this time, the soil has warmed up enough to facilitate root development, but the weather is still cool enough to allow the plants to establish themselves before the heat of summer arrives.

Planting rhubarb during this period also gives the plants plenty of time to grow and develop before they go dormant in the fall. When selecting a planting site, choose a location with well-draining soil and full sunlight to ensure healthy growth.

Keep in mind that rhubarb is a perennial plant, so choose a permanent location where the plants can thrive for many years. To promote strong root systems and vigorous growth, give the plants plenty of space, planting them about 3-4 feet apart.

How Late Can You Plant Rhubarb In Ohio?

The latest you should plant rhubarb in Ohio is early May, although planting in early spring is still preferable. By planting in May, you still give the plants enough time to establish their root systems before the hot summer weather arrives.

However, planting this late in the season may result in reduced yields during the first year, as the plants will have less time to grow and develop before going dormant in the fall. It is important to monitor the plants closely during their first summer, providing adequate water and nutrients to help them establish a strong root system.

Be prepared to wait an additional year before harvesting rhubarb planted this late, as the plants will need time to mature and produce a healthy crop. Remember that rhubarb is a long-lived perennial, so proper care during the first year is crucial to ensure a bountiful harvest in subsequent years.

What Type Of Soil Is Best For Planting Rhubarb In Ohio?

Rhubarb thrives in well-draining, fertile soil with a pH between 6.0 and 6.8. In Ohio, it is crucial to select a site with good drainage to prevent root rot and other diseases caused by excess moisture. Ideally, the soil should be rich in organic matter, as rhubarb is a heavy feeder and requires ample nutrients to produce healthy stalks.

To improve the fertility of your soil, incorporate compost, aged manure, or other organic matter before planting. This will not only provide essential nutrients but also improve the soil’s structure and water-holding capacity. Remember to test the soil pH before planting and amend with lime or sulfur as needed to achieve the optimal pH range for rhubarb.

How Much Sunlight Does Rhubarb Need In Ohio?

Rhubarb requires full sun to produce the best yields, which means at least six hours of direct sunlight per day. In Ohio, selecting a sunny location is crucial to ensure healthy growth and a bountiful harvest. Although rhubarb can tolerate some partial shade, too much shade may result in spindly stalks, reduced yields, and increased susceptibility to diseases.

When choosing a planting site, avoid locations where large trees or buildings may cast significant shadows on your rhubarb patch. Additionally, consider the orientation of your garden to maximize sunlight exposure throughout the day. By providing rhubarb with ample sunlight, you will encourage strong, vigorous growth and a productive harvest.

How Do You Prepare The Soil For Planting Rhubarb In Ohio?

Preparing the soil for planting rhubarb in Ohio involves several steps to ensure the plants receive the necessary nutrients and have the proper growing conditions. Start by testing your soil pH and amending it as needed to achieve a pH between 6.0 and 6.8.

Next, remove any weeds or grass from the planting area to reduce competition for nutrients and water. Incorporate a generous amount of organic matter, such as compost or aged manure, into the soil to improve fertility, structure, and drainage.

Dig planting holes that are approximately 12-18 inches deep and wide, spacing them 3-4 feet apart. When planting rhubarb crowns, place them 2-3 inches below the soil surface with the buds facing upwards. Finally, water the plants thoroughly and apply a layer of mulch around the base to help retain moisture and suppress weeds.

What Are The Best Rhubarb Varieties To Grow In Ohio?

Several rhubarb varieties are well-suited for growing in Ohio, offering different flavors, colors, and growth characteristics. Some popular options include:

  1. ‘Canada Red’ – Known for its sweet flavor and vibrant red stalks, this variety is an excellent choice for both cooking and fresh consumption.
  2. ‘Crimson Red’ – This variety produces thick, deep red stalks with a tart flavor that is perfect for pies and preserves.
  3. ‘Macdonald’ – With bright red stalks and a mild, sweet flavor, this variety is a favorite for home gardeners and is also popular at farmers’ markets.
  4. ‘Victoria’ – This heirloom variety produces large, greenish-red stalks with a tart, tangy flavor that is ideal for cooking.

How Do You Plant Rhubarb In Ohio?

To plant rhubarb in Ohio, follow these steps:

  1. Choose a planting site with well-draining soil and full sun exposure.
  2. Prepare the soil by incorporating organic matter and adjusting the pH as needed.
  3. Dig planting holes 12-18 inches deep and wide, spaced 3-4 feet apart.
  4. Place the rhubarb crown in the hole with the buds facing up, about 2-3 inches below the soil surface.
  5. Fill the hole with soil and gently firm it around the crown.
  6. Water the plant thoroughly and apply a layer of mulch around the base.

How Do You Care For Rhubarb Plants After Planting In Ohio?

Caring for rhubarb plants in Ohio involves regular watering, fertilizing, and proper maintenance to ensure healthy growth and a bountiful harvest. Water the plants deeply and consistently, providing about 1-1.5 inches of water per week, either through rainfall or supplemental irrigation.

Apply a balanced, slow-release fertilizer in early spring and again in late summer to provide essential nutrients. Remove any flower stalks that emerge, as allowing the plant to flower can reduce stalk production.

Keep the planting area free of weeds and maintain a layer of mulch to conserve moisture and suppress weed growth. In the fall, cut back the foliage to ground level and apply a thick layer of organic mulch to protect the crowns from freezing temperatures.

When Can You Harvest Rhubarb In Ohio?

In Ohio, you can typically begin harvesting rhubarb during the second year of growth, as the plants need time to establish strong root systems and mature during the first year. Harvesting usually begins in late April or early May and continues until the end of June or early July.

To harvest, select stalks that are at least 12 inches long and have a firm, crisp texture. Grasp the stalk near the base and gently twist and pull it away from the crown. It is important not to harvest all the stalks at once, as doing so can weaken the plant.

Leave at least one-third of the stalks on the plant to ensure it continues to produce energy for future growth. After the first few years, rhubarb plants can produce a bountiful harvest for up to 10-15 years if properly cared for and maintained.
