The Rubbermaid Structural Foam Stock Tank is a versatile and durable option for raised-bed gardening. This large, heavy-duty container, often used for livestock, also serves as an ideal raised-bed solution for those looking to grow plants efficiently in an urban or small backyard environment. This guide will walk you through the key aspects of assembling, maintaining, troubleshooting, and optimizing the Rubbermaid Structural Foam Stock Tank for gardening. Whether you are new to raised-bed gardening or an experienced gardener, these insights will help you maximize the potential of this product.

Assembly

The Rubbermaid Structural Foam Stock Tank requires minimal assembly, making it a convenient option for gardeners looking to get started quickly. However, a few steps need to be taken to prepare it for use as a raised bed.

1. Choosing the Right Location: Place the stock tank in an area that receives adequate sunlight. Most vegetables and herbs require at least 6 hours of direct sunlight per day.
2. Preparing the Ground: While the tank can be placed directly on soil, consider laying a weed barrier fabric or landscape cloth underneath it to prevent weeds from infiltrating the garden bed. Additionally, make sure the area is level to ensure proper water drainage.
3. Drilling Drainage Holes: The Rubbermaid Stock Tank is solid and does not come with pre-drilled drainage holes. You will need to drill a few holes at the bottom of the tank to prevent waterlogging. Drill at least 4-6 small holes to allow excess water to escape.
4. Lining the Tank: For optimal performance, consider lining the interior with landscape fabric to separate the soil from the tank’s surface. This helps extend the lifespan of the tank and minimizes direct contact with the soil, reducing the risk of wear over time.

Site Preparation

Proper site preparation is crucial to ensure your Rubbermaid Structural Foam Stock Tank performs at its best.

• Sunlight: Ensure the chosen location provides adequate sunlight for the plants you plan to grow. The tank will retain heat, which can be beneficial for certain crops, but it is important to monitor the soil temperature to avoid overheating.
• Level Ground: Place the tank on level ground to prevent water from accumulating unevenly at one side. Uneven watering can lead to poor plant growth and nutrient distribution.
• Soil Depth: Rubbermaid Stock Tanks typically have a depth of around 24 inches. This provides ample room for most root systems, but for deep-rooted plants, consider filling the bottom of the tank with gravel or rocks to reduce the overall soil volume and improve drainage.

Routine Upkeep

Routine maintenance of your Rubbermaid Structural Foam Stock Tank ensures it remains effective for years to come. This includes soil care, cleaning, and general upkeep.

• Soil Refresh: Annually, refresh the soil in the tank by removing the top few inches and replacing it with fresh compost or soil. This replenishes essential nutrients and improves the soil structure.
• Seasonal Cleaning: At the end of each growing season, clean the tank thoroughly to remove any plant debris or soil build-up. Use a mild soap solution and scrub the interior to prevent mold or mildew. Rinse thoroughly to avoid chemical residue.
• Check for Cracks: Over time, the tank’s surface may develop small cracks due to exposure to the elements. Regularly inspect for any damage and repair it promptly to avoid compromising the tank’s integrity.

Troubleshooting Common Issues

While the Rubbermaid Structural Foam Stock Tank is a durable and reliable option, some common issues can arise during setup or use.

• Warping: In extreme heat, the plastic material of the stock tank may warp. To prevent this, avoid placing the tank in areas that experience excessive direct heat, and ensure proper drainage to reduce water retention, which can also cause expansion of the material.
• Drainage Problems: If you notice that water is pooling in the tank, check the drainage holes. Ensure they are not blocked by soil, roots, or other debris. It is essential to maintain good drainage to avoid root rot.
• Pest Entry: While the stock tank is relatively secure, pests like rodents or insects can still enter if there are gaps. Install a fine mesh cover or line the perimeter of the tank with hardware cloth to prevent pests from infiltrating the soil.

Customization and Optimization for Higher Yields

The Rubbermaid Structural Foam Stock Tank can be customized in several ways to optimize plant growth, water efficiency, and soil health.

• Wicking Inserts: Consider installing a wicking system or moisture-retaining insert at the base of the tank to provide consistent water availability to the plants. This can help reduce water waste and prevent overwatering.
• Companion Planting Layout: Use the circular space of the tank to design efficient companion planting layouts. Certain plant pairings, such as tomatoes and basil, can thrive together, making the best use of space and improving plant health.
• Soil Health: Add organic matter such as compost or well-rotted manure to enrich the soil’s microbial content. This improves soil structure, nutrient availability, and supports healthier plant growth.

Comparison with Similar Raised-Bed Systems

When considering the Rubbermaid Structural Foam Stock Tank, it’s essential to compare it to similar raised-bed systems to determine which option is best suited for your needs.

• Versus Wooden Raised Beds: Unlike wood, which can decay over time, the Rubbermaid Stock Tank offers excellent durability, especially in wet conditions. However, it may not offer the aesthetic appeal of wooden beds, which blend more naturally into garden landscapes.
• Versus Metal Raised Beds: While metal raised beds can also be durable, they may heat up quickly in hot climates, which can stress plants. The foam insulation in the Rubbermaid Stock Tank provides better temperature regulation, keeping roots cooler during summer months.
• Versus Plastic Raised Beds: Other plastic raised beds may lack the strength and longevity of the Rubbermaid Stock Tank. The structural foam material of the Rubbermaid option offers superior impact resistance and greater long-term durability compared to standard plastic.

Compatibility with Add-Ons

The Rubbermaid Structural Foam Stock Tank is highly compatible with a range of garden add-ons, which can enhance its functionality.

• Trellis Frames: Install a trellis frame on the perimeter of the stock tank to support climbing plants such as beans or peas. This vertical growing space can help maximize the use of space within the tank.
• Mesh Pest Covers: To prevent pests from invading your raised bed, cover the tank with a mesh netting or pest cover. This can protect crops like lettuce and spinach from insects while still allowing airflow and light.
• Hoop-House Roofs: A hoop-house roof can be easily added to provide a protective cover against frost during colder months. This is especially beneficial for gardeners in cooler climates who wish to extend their growing season.
• Micro-Drip Irrigation: Installing a micro-drip irrigation system ensures that your plants receive consistent moisture without wasting water. This is a particularly useful addition for large or multiple stock tanks.
• Shade Cloths: If your tank is placed in an area with excessive sunlight, consider adding a shade cloth to prevent overheating and maintain optimal growing conditions for sensitive plants.
• Self-Watering Reservoirs: For added convenience and water efficiency, install a self-watering reservoir at the base of the tank. This allows the soil to absorb moisture as needed, reducing the frequency of watering.

By following this comprehensive checklist, you can ensure that your Rubbermaid Structural Foam Stock Tank serves as a reliable, durable, and highly productive raised bed for years to come. Whether you are growing herbs, vegetables, or flowers, this tank provides a strong foundation for a successful gardening experience.
