Imagine a summer day, the sun warming your face as you stroll through your garden, anticipating the sweet, tangy burst of fresh strawberries and the tart, robust flavor of rhubarb. The idea of harvesting these two garden favorites together might seem idyllic, but is it actually possible? Let's delve into the world of companion planting and explore whether strawberries and rhubarb make good neighbors.
Can You Successfully Grow Strawberries and Rhubarb Together?
The question of whether you can grow strawberries and rhubarb together is a common one among gardeners, and the answer is a bit nuanced. Technically, yes, youcangrow them together, but there are several factors to consider that will influence the success of your endeavor. Companion planting, the practice of growing different plants in close proximity for mutual benefit, can sometimes create a more thriving garden ecosystem. However, not all pairings are created equal, and understanding the specific needs of each plant is crucial.
Understanding Rhubarb's Needs
Rhubarb (Rheum rhabarbarum) is a hardy perennial vegetable known for its large leaves and tart stalks. Here's a breakdown of its key requirements:
- Space: Rhubarb plants need plenty of space to spread. A mature rhubarb plant can easily reach 3-4 feet wide.
- Sunlight: Rhubarb thrives in full sun (at least 6 hours of direct sunlight per day), but it can tolerate partial shade.
- Soil: Rhubarb prefers well-drained, fertile soil that is rich in organic matter. It also benefits from a slightly acidic to neutral soil p H (6.0-6.8).
- Watering: Rhubarb needs consistent watering, especially during dry periods.
- Nutrients: Rhubarb is a heavy feeder and benefits from regular fertilization, particularly with nitrogen-rich fertilizers.
Understanding Strawberry's Needs
Strawberries (Fragaria × ananassa) are beloved for their sweet, juicy fruits. Their needs include:
- Sunlight: Strawberries need at least 6-8 hours of direct sunlight per day.
- Soil: Strawberries prefer well-drained, slightly acidic soil (p H 5.5-6.5) that is rich in organic matter.
- Watering: Strawberries need consistent watering, especially during fruit development.
- Nutrients: Strawberries benefit from balanced fertilization, with an emphasis on phosphorus and potassium for fruit production.
- Space: While strawberries don't require as much space as rhubarb, they still need adequate room to spread and produce runners.
The Potential Challenges of Growing Strawberries With Rhubarb
While their basic needs appear similar on the surface, some potential conflicts can arise when growing strawberries with rhubarb:
- Competition for Resources: Rhubarb's large size and vigorous growth can quickly overshadow and outcompete strawberries for sunlight, water, and nutrients. This is the biggest hurdle when growing rhubarb and strawberries in the same area. The rhubarb will steal sunlight, water, and nutrients from the strawberries.
- Shading: Rhubarb's large leaves can create excessive shade, which can inhibit strawberry growth and fruit production. Strawberries need ample sunlight for optimal berry development.
- Nutrient Imbalance: Rhubarb's need for nitrogen may conflict with the specific nutrient requirements of strawberries, potentially leading to nutrient imbalances in the soil. This can especially be seen in the strawberries which will cause them to either not grow or produce less tasty berries.
- Disease Spread: Both strawberries and rhubarb can be susceptible to certain fungal diseases. Growing them together in close proximity could potentially increase the risk of disease spread.
Strategies for Successfully Growing Strawberries and Rhubarb in the Same Garden
Despite the potential challenges, it is possible to successfully grow strawberries and rhubarb together with careful planning and management. Here are some strategies to maximize your chances of success:
Strategic Planting and Spacing
The most crucial factor is to provide ample space between the plants. Plant rhubarb at one end of the garden bed and strawberries at the other, ensuring at least 4-5 feet of separation. This will help minimize competition for sunlight and resources. Consider also how the sun moves across your garden. Plant the rhubarb to the North of your strawberries to ensure the rhubarb does not block too much sunlight.
Sunlight Management
Monitor sunlight levels carefully. If the rhubarb is shading the strawberries, consider pruning some of the outer rhubarb leaves to allow more light to reach the strawberry plants. You can also use shade cloth strategically to protect the strawberries from excessive afternoon sun if needed.
Soil Preparation and Amendments
Prepare the soil thoroughly before planting, incorporating plenty of organic matter, such as compost or well-rotted manure. Conduct a soil test to determine the p H level and nutrient content. Amend the soil as needed to meet the specific requirements of both rhubarb and strawberries. Consider using separate soil amendments around each plant to tailor the nutrient levels to their individual needs.
Watering and Fertilization
Water deeply and regularly, especially during dry periods. Monitor the plants closely for signs of nutrient deficiencies and adjust your fertilization schedule accordingly. Consider using a balanced fertilizer formulated for fruits and vegetables. You may want to apply a higher nitrogen fertilizer to the rhubarb and a fertilizer higher in phosphorus and potassium to the strawberries.
Variety Selection
Consider choosing more compact rhubarb and strawberry varieties to minimize the competition for space and resources. Day-neutral strawberry varieties are a good option, as they produce fruit throughout the growing season, reducing the risk of being overshadowed by the rhubarb during peak fruiting times.
Regular Monitoring and Pruning
Regularly monitor both plants for signs of pests or diseases. Remove any affected foliage promptly to prevent the spread of problems. Prune rhubarb leaves as needed to maintain airflow and prevent excessive shading. Remove strawberry runners to prevent overcrowding and encourage fruit production.
Consider Raised Beds or Containers
If you're concerned about competition for resources or disease spread, consider growing strawberries in raised beds or containers. This allows you to control the soil composition, drainage, and nutrient levels more effectively.
Alternative Companion Plants for Strawberries and Rhubarb
While growing strawberries with rhubarb can be successful with careful management, there are other companion plants that may offer more direct benefits.
Good Companions for Strawberries
- Borage: Deters strawberry pests and attracts beneficial insects.
- Marigolds: Repel nematodes and other soil pests.
- Thyme: Acts as a ground cover and repels certain pests.
- Garlic and Onions: Deter certain pests and diseases.
- Beans: Helps fix nitrogen in the soil.
Good Companions for Rhubarb
- Brassicas (cabbage, broccoli, kale): These plants can help deter certain rhubarb pests.
- Legumes (peas, beans): Legumes fix nitrogen in the soil, which benefits rhubarb.
- Alliums (onions, garlic): These plants can help deter pests that may affect rhubarb.
By carefully selecting companion plants and implementing proper growing practices, you can create a thriving garden ecosystem that supports the health and productivity of both strawberries and rhubarb.
