Building an outdoor plant box with a built-in lock is a practical and secure way to store gardening tools or protect delicate plants. Here’s a step-by-step guide to help you create one:

Materials Needed:

- Pressure-treated lumber or cedar wood

- Screws and nails

- Hinges and a sturdy lock (e.g., padlock or latch lock)

- Waterproof sealant

- Drill and saw

- Measuring tape

Step 1: Design and Measurements

Decide the size of your plant box based on your needs. A common size is 3ft x 2ft x 2ft. Sketch a design, including the lock placement—typically on the lid.

Step 2: Cut the Wood

Cut the lumber into panels for the base, sides, and lid. Ensure the lid is slightly larger than the box opening to accommodate the lock.

Step 3: Assemble the Box

Attach the side panels to the base using screws. Reinforce the corners for stability. Leave the front panel slightly shorter if adding a hinged lid.

Step 4: Install the Lid and Lock

Attach the lid with hinges. Drill holes for the lock mechanism, ensuring it aligns properly. Test the lock for smooth operation.

Step 5: Seal and Finish

Apply waterproof sealant to protect the wood from weather damage. Let it dry before placing plants or tools inside.

This DIY project combines functionality and security, making it perfect for gardeners who need extra storage or protection. Customize the design to fit your outdoor space!
