2. Setup and Installation
2.1 Tools and Materials Required
- Stud Finder (for mounting on siding)
- Level
- Measuring Tape
- Pencil
- Drill with appropriate bits (for wood or masonry)
- Wood Strapping (for mounting on siding)
- Screws (appropriate for your wall type)

2.2 Mounting on Siding
Follow these steps to securely mount your window box on siding:
- Locate Studs: Use a stud finder to locate and mark the studs on your wall where the window box will be installed.
- Secure Wood Strapping: Attach wood strapping to the wall, ensuring it is level and securely fastened to the studs. This provides a stable base for the brackets.
- Install Brackets: Position the window box brackets 12 inches apart on the wood strapping. Use a level to ensure they are straight. Secure the brackets using a drill and appropriate screws.
- Attach Window Box: Carefully lift the window box and align its bottom molded ridges with the installed brackets. Press down firmly until you hear and feel it click into place, ensuring it is flush with the brackets.

2.3 Mounting on Brick Wall
For brick wall installations, a hammer drill and masonry screws are recommended:
- Find Starting Point: Identify the center of your desired space and mark where your brackets will go. Placement may vary depending on the size and style of your window box.
- Check for Level: Use a level to ensure your markings are straight.
- Mark and Drill Holes: Mark the pilot holes for the brackets. Use a hammer drill to drill pilot holes into the brick or wall surface.
- Install Brackets: Secure the first bracket with masonry screws. Repeat for all remaining brackets, ensuring they are evenly spaced and level.
- Attach Window Box: Line up the bottom molded ridges of the window box with the brackets. Press down firmly until it clicks into place.

2.4 Optional: Installing Decorative Corbels
To add a decorative touch, you can install corbels to the outermost window box brackets:
- Position Corbel: Ensure the front lip of the wall mount bracket sits flush against the inside face of the corbel.
- Secure Corbel: Use two 1-inch steel screws to secure each corbel to the bottom of the wall mount bracket. Repeat for the other side.

2.5 Planting and Filling
Once the window box is securely mounted:
- Add Filler: Place a layer of lightweight filler at the bottom of the planter to reduce the amount of potting mix needed and improve drainage.
- Add Potting Mix: Fill the planter with high-quality potting mix, leaving enough space for your plants.
- Plant Flowers/Greenery: Arrange and plant your desired flowers or greenery.
- Fill Water Reservoir: Use a hose or watering can to fill the integrated water reservoir. You can also drill a 3/4 inch hole in the top or back for direct access to the reservoir.

3. Operating Instructions
3.1 Self-Watering System
The Nantucket Window Box features a self-watering system with a built-in reservoir. This system provides a consistent water supply to your plants, reducing the frequency of manual watering. Simply fill the reservoir, and the plants will draw water as needed. The overflow drainage prevents overwatering.
3.2 Watering Frequency
Monitor your plants and the reservoir level. In hot or dry conditions, you may need to refill the reservoir more frequently. The self-watering feature is designed to keep plants hydrated for extended periods, but regular checks are still recommended.
4. Maintenance
4.1 Cleaning
To maintain the appearance of your polyethylene window box, regular cleaning is advised. You can easily hose off dirt and debris. For more thorough cleaning, especially for white products, follow these steps:
- Place on Level Surface: Position your window box on a firm, level surface.
- Use Pressure Washer: Set your pressure washer to its maximum setting.
- Clean at Close Proximity: Use the pressure washer at close proximity for maximum effect. Since the product is molded entirely of polyethylene, there is no risk of damage.
Video: This official Mayne video provides instructions on how to clean white polyethylene products using a high-power pressure washer.
4.2 Seasonal Care
The Mayne Nantucket Window Box is designed for all seasons. Its UV-resistant and weather-resistant properties ensure lasting elegance and durability. In colder climates, ensure proper drainage to prevent ice buildup that could potentially damage the planter or plants.
5. Troubleshooting
If you encounter any issues with your Mayne Nantucket Window Box, consider the following:
- Water Drainage: Ensure the overflow drainage holes are clear of debris to prevent waterlogging.
- Plant Health: If plants are not thriving, check the water reservoir level and ensure they are receiving adequate sunlight and nutrients.
- Stability: Periodically check the mounting brackets and screws to ensure the window box remains securely attached to the wall.
