1. Introduction
Thank you for choosing the KING BIRD Raised Garden Bed with Cover. This manual provides essential information for the safe assembly, operation, and maintenance of your new galvanized oval planter. Please read these instructions thoroughly before beginning assembly or use.
Important Safety Information
WARNING: This greenhouse has sharp edges on the galvanized steel frame. Handle with care during assembly and use. The polyethylene cover is susceptible to UV damage, so avoid prolonged exposure to direct sunlight when not in use or during extreme heat. The zippered screen door should be handled carefully to prevent damage or injury. Always follow proper assembly, use, and maintenance instructions to ensure safety.
2. Components List
Before assembly, ensure all parts are present and undamaged. Refer to the diagram below for identification.
- Galvanized Steel Panels (curved and flat sections)
- Connecting Hardware (screws, nuts, washers)
- Rubber Edge Trim (for top edge of bed)
- Greenhouse Cover (Polyethylene, with zippered doors and ties)
- Frame Poles for Cover
- Crossbars (for structural support of the bed)


3. Setup and Assembly
Follow these steps to assemble your raised garden bed and install the cover.
- Prepare the Area: Choose a level location with adequate sunlight for your plants. Clear any debris or rocks from the area.
- Assemble the Base Panels: Connect the galvanized steel panels using the provided screws and nuts. Ensure the panels are aligned correctly to form the oval shape. The unboxing video demonstrates the types of panels and hardware.
- Install Crossbars: Attach the metal crossbars across the width of the bed. These provide structural integrity and prevent bowing once filled with soil.
- Apply Edge Trim: Place the rubber edge trim along the top rim of the assembled galvanized bed. This covers any sharp edges for safety.
- Assemble Cover Frame: Construct the frame for the greenhouse cover using the provided poles. Follow the diagrams in the included paper manual for correct pole connections.
- Attach Greenhouse Cover: Drape the polyethylene cover over the assembled frame. Secure it to the base of the garden bed using the integrated straps or ties. Ensure the zippered doors are functional.

4. Operating Instructions
Filling the Garden Bed
Fill the raised bed with a suitable soil mix for your chosen plants. The bed requires approximately 10 cubic feet of soil.
Planting and Watering
Plant your vegetables, flowers, or herbs according to their specific needs. Water thoroughly after planting. The bottomless design allows for excellent drainage and root growth into the native soil.


Using the Greenhouse Cover
- Seedling Protection: The cover helps maintain a warmer internal temperature (40-50°F higher than outside), ideal for starting seedlings in early spring and extending the growing season.
- Microclimate Control: Utilize the zippered doors to regulate temperature and humidity, creating an optimal environment for plant growth. Open doors for ventilation and pollination, close them for protection.
- Pest and Animal Protection: The cover acts as a barrier against pests and small animals, safeguarding your plants.
- Access: The zippered screen doors provide easy access for watering, planting, and harvesting.



5. Maintenance
Proper maintenance will extend the lifespan of your raised garden bed and cover.
- Cleaning: Periodically clean the galvanized steel panels and the polyethylene cover with mild soap and water. Avoid abrasive cleaners that could damage the materials.
- Cover Care: The polyethylene cover is designed for durability but can be affected by prolonged UV exposure. Consider removing or partially shading the cover during intense summer heat or when not actively needed to prolong its life. Secure the cover firmly during windy conditions.
- Inspection: Regularly inspect all screws and connections for tightness. Check the cover for any tears or damage and repair as needed to maintain its protective qualities.
- Winterization: In regions with heavy snowfall, it is recommended to remove the cover to prevent snow accumulation from damaging the frame. The galvanized bed itself is weather-resistant.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water pooling on cover | Insufficient tension or sagging frame. | Ensure cover is taut and frame poles are securely connected. Clear accumulated water promptly. |
| Bed panels bowing outwards | Soil pressure, crossbars not installed or loose. | Verify crossbars are correctly installed and tightened. Do not overfill with soil. |
| Pests entering the covered bed | Gaps in cover, unzipped doors. | Ensure all zippers are closed and the cover is securely fastened to the base. Check for tears in the mesh. |
| Plants wilting despite watering | Excessive heat build-up under cover. | Open zippered doors for ventilation, especially on sunny days, to prevent overheating. |
