How To Make Wooden Flower Boxes?

Creating wooden flower boxes is a rewarding DIY project that can enhance the beauty of your garden or patio. With a few basic tools and materials, you can build a planter that not only adds aesthetic appeal but also provides a functional space for your plants. In this guide, we will walk you through the process of making wooden flower boxes, from preparation to completion.

Choosing the Right Materials

When it comes to building wooden flower boxes, the choice of materials is crucial. Cedar, pine, and treated lumber are popular options due to their durability and resistance to rot. Cedar is particularly favored for its natural resistance to insects and its pleasant aroma. However, it can be more expensive than other types of wood. Treated lumber, on the other hand, is cost-effective and suitable for outdoor use, but it may contain chemicals that could leach into the soil.

For a modern look, you might consider using cedar fence boards, which can be rough but can be smoothed out with a planer and sandpaper. The tools needed for this project include a miter saw, drill, sandpaper, and a nail gun. If you're aiming for a more rustic appearance, you can use untreated wood and skip the sanding process.

Preparing the Boards

Before you start building, it's essential to prepare your boards. Cut them according to your planter design, ensuring that all pieces fit together perfectly. If using rough wood like cedar fence boards, start by running them through a planer to remove excess roughness. Then, sand the boards with progressively finer grits of sandpaper (60, 120, 150, and 220) to achieve a smooth finish.

Building the Planter Box

Assembling the Sides

1. Cutting the Boards: Use a miter saw to cut the boards into the required lengths for the sides and bottom of the planter.

2. Assembling the Sides: Lay out the side boards and attach them together using wood glue and nails. Ensure they are aligned properly and use clamps to hold them in place until the glue dries.

3. Adding Supports: Attach 2x2 supports at the corners inside the planter box for added stability. Use wood glue and nails to secure these supports.

Adding the Bottom and Top

1. Bottom Panel: Cut the bottom panel to fit inside the planter box. Attach it using wood screws or nails. If you plan to plant directly in the box, consider adding drainage holes.

2. Top Trim: Add a decorative trim around the top of the planter box. This can be done using angled pieces of wood nailed into place.

Building a Stand for the Planter

If you want to elevate your planter, building a stand is a great option. Here’s how you can do it:

1. Cutting the Legs: Cut four legs from 2x2 lumber to the desired height.

2. Assembling the Frame: Use pocket hole screws to attach the legs together, forming a sturdy frame.

3. Attaching the Planter: Place the planter box on the stand and secure it with screws if desired.

Finishing Touches

Once your planter box and stand are built, it's time to add a finish. You can stain or paint the wood to match your outdoor decor. For outdoor use, apply a clear coat of spar urethane to protect the wood from the elements.

Tips for Beginners

• Use Simple Tools: You don't need a lot of specialized tools to build a planter box. A miter saw and a nail gun are sufficient.

• Choose the Right Wood: Consider the durability and cost of the wood you choose.

• Add Drainage: If planting directly in the box, ensure there are drainage holes to prevent waterlogged soil.

Common Mistakes to Avoid

• Incorrect Measurements: Double-check your measurements before cutting the wood.

• Insufficient Support: Ensure that the planter box has enough internal support to hold the weight of the soil and plants.

• Lack of Drainage: Always add drainage holes if planting directly in the box.
