How to Build an Elevated Planter Box

Are you looking to add a touch of greenery to your outdoor space? Building an elevated planter box can be a great way to grow plants, flowers, and vegetables while also adding a stylish element to your garden or patio. In this article, we will guide you through the step-by-step process of constructing your own elevated planter box using the best materials and techniques.


Before diving into the construction process, it’s important to gather all the necessary materials. Cedar is highly recommended as one of the best materials for elevated planter box construction. It is naturally resistant to rot, decay, and insect damage, making it an ideal choice for outdoor projects. Furring strips can also be used as a cost-effective alternative to cedar.

Planter Box Design

There are various designs and sizes of planter boxes to choose from. You can opt for a rectangular shape, square shape, or even a tiered design to accommodate different plants and space requirements. Take into consideration the dimensions of the area where you plan to place the planter box, as well as the types of plants you wish to grow.

Step-by-Step Guide

Now let’s dive into the step-by-step process of building your elevated planter box:

  1. Measure and Cut the Wood: Start by measuring and cutting the cedar or furring strips according to your desired planter box dimensions. It is important to ensure that all the pieces are cut accurately to ensure a sturdy structure.
  2. Predrill Holes: Before securing the pieces together, predrill holes in the boards to prevent splitting. Use a drill bit slightly smaller than the diameter of the screws you will be using.
  3. Attach Boards: Begin assembling the planter box by attaching the boards together. Use screws or nails to secure the pieces, ensuring a tight fit.
  4. Secure the Structure: To ensure the planter box is sturdy, use hex screws to secure the structure. Place the screws at regular intervals along the corners and edges of the box.
  5. Add Drainage Holes: To prevent waterlogging, drill drainage holes at the bottom of the planter box. This will allow excess water to escape, keeping your plants healthy.
  6. Apply Finish: If desired, you can apply a protective finish to the planter box. This will help prolong its lifespan and enhance its appearance.
  7. Fill with Soil: Once the planter box is complete, fill it with a high-quality potting mix or soil suitable for the types of plants you will be growing. Ensure that the soil depth is appropriate for the root systems of your chosen plants.
  8. Planting: Now it’s time to start planting! Choose plants that thrive in elevated planter boxes, such as herbs, flowers, or vegetables.


Building an elevated planter box can be a rewarding DIY project that adds beauty and functionality to your outdoor space. By following the step-by-step guide outlined in this article, using cedar or furring strips as recommended materials, and paying attention to design and construction details, you can create a sturdy and attractive planter box to showcase your favorite plants.
