How To Build A Planter Box


If you’re looking to add a touch of greenery to your outdoor space or want to grow your own herbs and flowers, building a planter for snake plants or for any other plants is a fantastic project to undertake. Not only does it provide a dedicated space for your plants, but it also adds a decorative element to your garden or patio. In this article, we will guide you through the process of building a planter box from scratch.

Benefits of Having a Planter Box

Before we dive into the nitty-gritty of building a planter box, let’s explore the benefits of having one in your outdoor space. Planter boxes offer several advantages, such as:


Planter boxes come in various sizes and shapes, allowing you to customize them to fit your available space and personal style.


Unlike traditional garden beds, planter boxes can be easily moved around, making them perfect for renters or those who like to rearrange their outdoor setup.

Weed and Pest Control

By elevating your plants in a planter box, you can minimize the risk of weeds and pests infiltrating your garden.

Improved Drainage

Planter boxes typically have drainage holes, ensuring that your plants’ roots don’t sit in water, which can lead to root rot.


Raised planter boxes make gardening more accessible, especially for those with mobility issues or disabilities.

Choosing the Right Materials

When it comes to selecting the materials for your planter box, there are a few options to consider:


Cedar, redwood, and cypress are popular choices for wooden planter boxes due to their durability and resistance to rot. Make sure to use untreated wood or opt for food-safe sealants if you plan to grow edible plants.


Plastic planter boxes are lightweight, affordable, and require minimal maintenance. Look for UV-resistant options to prevent fading and brittleness over time.


Aluminum and galvanized steel planter boxes are sturdy and provide a modern aesthetic. However, be cautious with metal options as they can retain heat, potentially harming your plants’ roots.

Tools and Supplies Needed

Before you start building your planter box, gather the following tools and supplies:

  • Tape measure
  • Saw
  • Drill
  • Screws
  • Sandpaper
  • Wood glue
  • Safety goggles
  • Work gloves
  • Paint or stain (optional)
  • Brush or roller (optional)

Now, let’s walk through the process of building a planter box step by step:

Measuring and Cutting the Wood

Begin by measuring and cutting the boards for the front, back, and sides of the planter box according to your desired dimensions. Use a tape measure and a saw to ensure precise cuts.

Assembling the Box

Lay out the cut boards to form the four sides of the planter box. Apply wood glue along the edges and use screws to secure the boards together. Make sure the corners are square and the box is sturdy.

Adding Drainage Holes

To prevent waterlogging and ensure proper drainage for your plants, drill several small holes in the bottom of the planter box. This will allow excess water to escape and prevent root rot.

Sanding and Finishing

Smooth out any rough edges or surfaces using sandpaper. This will not only make the planter box look more polished but also prevent splinters. If desired, you can apply a coat of paint or stain to enhance the appearance and protect the wood.

Optional: Adding Trellis or Legs

Depending on your plant preferences and design aesthetic, you can attach a trellis to the back of the planter box for climbing plants or add legs to elevate it off the ground. These additions can enhance the functionality and visual appeal of your planter box.

Tips for Maintaining Your Planter Box

Once your planter box is built, here are some tips to help you maintain it and keep your plants thriving:

Watering and Drainage

Ensure proper watering by checking the moisture level of the soil regularly. Avoid overwatering, as it can lead to root rot. Monitor the drainage holes to ensure they remain clear and unclogged.

Pest Control

Keep an eye out for pests that may damage your plants. Use organic pest control methods or natural repellents to protect your plants without harming the environment.

Cleaning and Repairs

Regularly clean the planter box by removing any debris or dead leaves. If you notice any signs of damage or wear, such as loose screws or cracked boards, repair them promptly to maintain the structural integrity of the box.


Building a planter box is a rewarding and practical project that allows you to showcase your gardening skills and enhance the beauty of your outdoor space. By following the step-by-step guide provided in this article, you can create a customized planter box that suits your needs and preferences. Enjoy the process of planting and nurturing your favorite flowers, herbs, or vegetables in your newly built planter box.
