Planter boxes are a great way to add beauty and greenery to your outdoor space. Whether you have a small balcony or a spacious garden, a planter box can help you grow flowers, herbs, or vegetables right at home. In this article, we will guide you through the process of making a planter box, from selecting the materials to assembling the box itself.

Selecting the Materials

The first step in making a planter box is to choose the right materials. Here are some popular options:

  • Wood: Cedar and redwood are excellent choices for planter boxes as they are naturally resistant to rot and insect damage. They also have an attractive appearance.
  • Plastic: Plastic planter boxes are lightweight, affordable, and come in a variety of colors and styles. However, they may not be as durable as wooden options.
  • Metal: Metal planter boxes, such as those made from galvanized steel or corten steel, are sturdy and can add a modern touch to your outdoor space.
  • Concrete: Concrete planter boxes are durable and can withstand harsh weather conditions. They can be made in various shapes and sizes.

Measuring and Cutting the Materials

Once you have selected the material for your planter box, it’s time to measure and cut the pieces. Here’s how:

  • Measure the desired length, width, and height of your planter box. Use a tape measure to ensure accurate measurements.
  • Using a saw or a similar cutting tool, cut the pieces according to the measurements. Make sure to wear safety goggles and work in a well-ventilated area.

Assembling the Planter Box

Now that you have the pieces ready, it’s time to assemble the planter box. Follow these steps:

  • Lay out the bottom piece and attach the side pieces to it using screws or nails. Make sure the edges are flush and the corners are square.
  • Attach the remaining side pieces to the box, securing them with screws or nails.
  • If desired, add a support piece in the middle of the box to prevent bowing or sagging.
  • Drill drainage holes in the bottom of the planter box to allow excess water to escape. This will prevent root rot and other water-related issues.

Finishing Touches

Once your planter box is assembled, you can add some finishing touches to enhance its appearance and functionality. Here are a few ideas:

  • Apply a coat of weatherproof sealant or paint to protect the wood or metal from the elements.
  • Add a layer of landscape fabric or a liner to the bottom of the planter box to prevent soil from escaping through the drainage holes.
  • Fill the planter box with high-quality potting soil and choose the appropriate plants for your space and climate.
  • Consider adding trellises or stakes to support climbing plants and create a vertical garden.


Making a planter box is a rewarding DIY project that allows you to personalize your outdoor space and grow your favorite plants. By selecting the right materials, measuring and cutting accurately, and assembling the box carefully, you can create a beautiful and functional planter box that will bring joy for years to come. Don’t forget to add finishing touches to protect the box and support your plants. Happy gardening!
