The Rubbermaid Structural Foam Stock Tank is a robust, versatile, and durable option for raised-bed gardening. With its strong construction and large capacity, it provides a perfect environment for growing leafy greens, which thrive in consistent moisture, well-drained soil, and adequate space for root expansion. This guide will walk you through the process of assembling, preparing the site, troubleshooting common issues, and optimizing the tank for maximum yields. Whether you are new to gardening or an experienced grower, this article offers practical advice tailored to the Rubbermaid Structural Foam Stock Tank.

Assembly of the Rubbermaid Structural Foam Stock Tank

Tools Required

• Rubbermaid Structural Foam Stock Tank
• Level (for ensuring a flat surface)
• Gardening gloves
• Shovel or spade
• Hose or watering can
• Drill (if needed for drainage hole modification)

Step-by-Step Assembly

1. Unbox and Inspect: Unbox your Rubbermaid Structural Foam Stock Tank and ensure that it is intact without any visible cracks or damage. The tank is typically made from durable, UV-resistant foam, which helps with insulation and structural integrity.
2. Choose the Location: Select a flat, level surface with access to sunlight for at least 6–8 hours a day. Leafy greens require ample light, but too much direct sun during hot weather can lead to wilting, so partial shade may also be beneficial, especially in warmer climates.
3. Install the Tank: Place the stock tank on the chosen site. Ensure that the base of the tank is level to prevent water pooling in uneven areas. If necessary, use a level tool to check.
4. Create Drainage: While the Rubbermaid tank may come with a few pre-drilled holes, adding additional drainage is essential for leafy greens. Drill several holes along the bottom of the tank to promote proper water drainage. This will help prevent root rot.
5. Fill with Soil: Fill the tank with a good-quality, well-draining potting mix. A blend that includes organic matter, such as compost, and perlite or vermiculite, is ideal. Aim for a soil depth of at least 12 inches to accommodate the deep root systems of leafy greens like spinach, kale, and lettuce.

Site Preparation for Planting Leafy Greens

Proper site preparation is crucial for ensuring healthy, fast-growing leafy greens.

Soil and Fertilization

• Soil Type: Leafy greens perform best in slightly acidic to neutral soil (pH between 6.0 and 7.0). The Rubbermaid Structural Foam Stock Tank provides a contained growing space, so it’s essential to start with nutrient-rich, loose soil.
• Fertilization: Before planting, amend the soil with organic fertilizer. Leafy greens are heavy feeders and will benefit from a balanced nutrient mix. Organic options like compost, worm castings, or fish emulsion will provide long-lasting nutrients throughout the growing season.
• Moisture Management: Leafy greens need consistent moisture, but they do not tolerate standing water. Ensure that the tank has adequate drainage to prevent waterlogged soil. During dry spells, a consistent watering schedule is necessary to keep the soil evenly moist.

Companion Planting Layouts

Companion planting can optimize space and encourage healthier plants. Consider planting herbs such as basil or cilantro alongside your leafy greens to naturally repel pests and improve flavor. Avoid planting with crops that require significantly different care, such as tomatoes or cucumbers, which can outcompete your greens for resources.

Routine Upkeep and Maintenance

Soil Refresh

• Seasonal Soil Refresh: Every year, remove the top 2-3 inches of soil to refresh the growing medium. Replace it with fresh compost and new potting mix to maintain soil fertility. This helps prevent nutrient depletion and improves soil structure.
• Crop Rotation: Rotate your crops annually to prevent soil-borne diseases and nutrient imbalances. If you’ve grown leafy greens in the tank for one season, try planting root vegetables or legumes in the next to fix nitrogen in the soil and reduce the risk of pests.

Seasonal Cleaning

• Winterizing: In colder climates, consider moving the Rubbermaid tank to a sheltered area during winter. If it remains outside, clean it thoroughly and allow it to dry to prevent mold and mildew buildup. For extended periods of freezing temperatures, it’s advisable to empty the tank and store it indoors to prolong its lifespan.
• Cleaning After Each Harvest: After every harvest, remove any plant debris and clean the tank with a mild solution of soap and water. This helps minimize the spread of pests and diseases.

Troubleshooting Common Setup Issues

Warping or Cracking

While the Rubbermaid Structural Foam Stock Tank is built to be durable, prolonged exposure to extreme temperature fluctuations can cause warping or cracking. To prevent this:

• Location: Place the tank in a shaded area or use UV-resistant covers to protect it from the sun’s intense heat.
• Storage in Winter: During extremely cold weather, empty the tank and store it in a dry, sheltered location to prevent damage from freezing temperatures.

Drainage Problems

If you notice water pooling in your tank, you may need to adjust your drainage setup.

• Check Drain Holes: Ensure that the drainage holes are not blocked by soil or debris. If necessary, increase the number of holes to improve drainage.
• Elevate the Tank: Raising the tank slightly off the ground with bricks or pavers can improve drainage by allowing excess water to escape more easily.

Pest Entry

While the Rubbermaid tank is fairly secure, pests like aphids, snails, or rodents may still find their way in.

• Mesh Covers: Consider adding a mesh pest cover or frame to keep pests out.
• Check for Gaps: Inspect the edges of the tank for any small gaps or openings where pests can enter, and seal them if possible.

Customization and Optimization for Higher Yields

Wicking Inserts

Incorporating a wicking system into the Rubbermaid tank can improve water efficiency and ensure your leafy greens receive consistent moisture. These systems draw water from a reservoir below the soil, reducing the frequency of manual watering.

Water Efficiency

• Drip Irrigation: Installing a micro-drip irrigation system can deliver water directly to the roots of your leafy greens, minimizing waste and reducing the risk of soil erosion.
• Self-Watering Reservoir: Pairing your Rubbermaid tank with a self-watering reservoir can help maintain consistent moisture levels. These systems are especially useful in hot climates where daily watering might be needed.

Trellis Frames and Hoop-House Roofs

For leafy greens that grow tall or require extra support, consider adding a trellis frame or a hoop-house roof to the Rubbermaid tank. These additions will keep plants upright and protect them from strong winds or heavy rainfall.

Compatibility with Add-Ons

The Rubbermaid Structural Foam Stock Tank is highly compatible with a variety of gardening accessories. Here’s how you can enhance your setup:

• Trellis Frames: These are ideal for plants like climbing greens (e.g., vertical lettuce or arugula) that need support.
• Mesh Pest Covers: A mesh cover helps protect your leafy greens from pests while still allowing sunlight and rainwater to nourish the plants.
• Shade Cloths: Use shade cloths to protect your greens from scorching summer heat. These are particularly useful in areas where afternoon sun can stress the plants.
• Micro-Drip Irrigation: Integrating a drip irrigation system ensures that your greens are watered efficiently, promoting healthier growth and reducing the chance of overwatering.
• Self-Watering Reservoir: Pairing the tank with a self-watering system can reduce the need for manual watering, especially during dry spells.

Comparison with Similar Raised-Bed Systems

When compared to other raised-bed systems, the Rubbermaid Structural Foam Stock Tank stands out due to its robust construction and large size. Unlike wooden or plastic beds, the Rubbermaid tank is designed to withstand harsh weather conditions and last for many years. Its insulated foam construction helps maintain temperature stability, making it an excellent choice for year-round gardening. Additionally, its ease of assembly and versatility make it a preferred option for urban gardeners with limited space.
