27 Things to Grow With Rhubarbs: Rhubarb Companion Planting

Companion planting is a gardening technique that involves planting different plants together to benefit each other. By strategically placing certain plants next to each other, gardeners can create a harmonious and mutually beneficial environment for their crops. Rhubarb is a perennial vegetable that is known for its tart and tangy stalks, which are commonly used in pies, jams, and other culinary creations. In addition to its delicious flavor, rhubarb also offers a range of benefits when used as a companion plant.

Benefits of Rhubarb Companion Planting

One of the main benefits of rhubarb companion planting is improved soil health. Rhubarb has deep roots that help to break up compacted soil and improve drainage. This can be especially beneficial for plants that have shallow roots, as it allows them to access nutrients and water more easily. Additionally, rhubarb leaves contain high levels of calcium, which can help to balance the pH of the soil and make it more fertile.

Another benefit of rhubarb companion planting is increased yield and growth of rhubarb itself. When planted alongside certain companion plants, rhubarb can experience enhanced growth and productivity. This is because some plants have the ability to repel pests or attract beneficial insects, which can help to protect the rhubarb plant and promote its overall health.

How to Plant Rhubarb with Companion Plants

When planting rhubarb with companion plants, there are a few key steps to follow to ensure success. Here is a step-by-step guide on how to plant rhubarb with companion plants:

1. Choosing the right location: Rhubarb prefers a sunny location with well-draining soil. Choose a spot in your garden that receives at least six hours of direct sunlight each day and has soil that is rich in organic matter.

2. Preparing the soil: Before planting, prepare the soil by removing any weeds or grass and loosening it with a garden fork or tiller. Add compost or well-rotted manure to improve the fertility and structure of the soil.

3. Planting rhubarb and companion plants: Dig a hole that is wide and deep enough to accommodate the root ball of the rhubarb plant. Place the plant in the hole, making sure that the crown is level with or slightly above the soil surface. Backfill the hole with soil, firming it gently around the plant. Space companion plants according to their specific requirements, taking into consideration their mature size and growth habit.

4. Proper spacing: When planting rhubarb with companion plants, it is important to leave enough space between each plant to allow for proper air circulation and prevent overcrowding. Follow the spacing recommendations for each specific plant to ensure optimal growth and productivity.

Tips for Maintaining Rhubarb Companion Planting

Once you have planted your rhubarb with companion plants, it is important to provide proper care and maintenance to ensure their success. Here are some tips for maintaining rhubarb companion planting:

1. Regular watering: Rhubarb and its companion plants require regular watering to stay healthy and productive. Water deeply and consistently, making sure that the soil is evenly moist but not waterlogged. Avoid overhead watering, as this can promote the spread of diseases.

2. Mulching: Mulching around the base of the plants can help to conserve moisture, suppress weeds, and regulate soil temperature. Use organic mulch, such as straw or wood chips, and apply a layer that is two to three inches thick.

3. Fertilizing: Rhubarb and its companion plants benefit from regular fertilization to ensure optimal growth and productivity. Apply a balanced organic fertilizer, such as compost or well-rotted manure, in early spring and again in midsummer.

4. Pruning: Rhubarb does not require much pruning, but it can benefit from the removal of any dead or damaged leaves or stalks. This can help to improve air circulation and prevent the spread of diseases.
