Creating a window-mounted outdoor plant box is a fantastic way to add greenery to your home without sacrificing space. Follow these simple steps to build your own sturdy and stylish planter box.

Materials Needed:

- Wooden boards (cedar or redwood recommended for durability)

- Measuring tape and pencil

- Saw (hand saw or electric)

- Drill and screws

- Sandpaper

- Waterproof sealant or paint

- L-brackets for mounting

- Potting soil and plants

Step 1: Measure and Cut the Wood

Measure the width of your window and cut the wooden boards to size. You’ll need a base, two side panels, a front panel, and a back panel. Sand the edges to prevent splinters.

Step 2: Assemble the Box

Attach the side panels to the base using screws. Then, secure the front and back panels. Ensure all corners are square for stability.

Step 3: Add Drainage Holes

Drill small holes in the base to allow excess water to drain. This prevents root rot and keeps plants healthy.

Step 4: Seal the Wood

Apply a waterproof sealant or outdoor paint to protect the wood from moisture and weather damage. Let it dry completely.

Step 5: Mount the Box

Use L-brackets to attach the planter box securely beneath your window. Ensure the brackets are screwed into studs or sturdy framing for support.

Step 6: Fill and Plant

Add potting soil and your favorite plants or flowers. Water them thoroughly and enjoy your new window garden!

This DIY project is perfect for beginners and adds charm to any home. Happy planting!
