How to Make Planter Boxes for Trees

Planting trees in planter boxes not only enhances the beauty of your outdoor space but also helps in reducing air pollution. Planter boxes are easy to move and maintain, making them the perfect choice for urban landscapes. In this article, we will provide you with a step-by-step guide on how to make planter boxes for trees.

Step 1: Choose the Right Size Planter Box

The first step in making a planter box for a tree is to choose the right size box. Determine the size of the tree and add an extra 12 inches to both the height and the width for the root ball. Keep in mind that the tree’s roots need ample space to grow, so it’s better to go for a larger planter box than a smaller one.

Step 2: Buy the Necessary Materials

To make a planter box for a tree, you will need materials such as wood planks, nails, screws, saw, drill, sandpaper, and a liner. Choose a liner that is at least 10 mil thick to prevent water from seeping through, which can cause the wood to rot. You can also use plastic planters as liners, but ensure that they have good drainage.

Step 3: Construct the Planter Box

Once you have all the materials, it's time to construct the planter box. Cut the wood planks to the required length, and nail them together to form the sides of the planter box. Ensure that the corners are square, or else the planter box won't be stable. Once you have the frame, drill holes at the bottom to allow for drainage.

Step 4: Add the Liner

Once the frame is complete, now is the time to add the liner. Line the planter box with a plastic liner or a landscape fabric. Ensure that the liner has a lot of excess at the top so that you can fold it over the edges of the planter box. Cut any excess liner material that is protruding from the top of the edges.

Step 5: Sand and Finish the Planter Box

If you plan to paint or stain the planter box, sand the wood until it's smooth. Apply a wood stain or paint that is safe for outdoor use. You can also oil the wood for a natural look.

Step 6: Plant the Tree in the Planter Box

Once the planter box is complete, it's time to plant the tree. Fill the planter box with good-quality soil that is suitable for the tree species. Add slow-release fertilizer to boost the growth of the tree. Plant the tree, and ensure that the root ball is level with the soil. Water the tree thoroughly and add mulch to retain moisture.

Conclusion

Making planter boxes for trees is an excellent way to enhance the beauty of your outdoor space while also helping the environment. With this step-by-step guide, you can make your planter box easily, and ensure that your tree grows healthy and strong. Follow the steps carefully, and you will create a beautiful planter box that will make your yard the envy of all your neighbors.
