1) Gather Tools. Building a planter box from wood requires basic tools such as a saw, power drill and sander. You’ll also need screws, a screen and a paint brush. 2) Select Lumber. Selecting the right lumber for your DIY planter project is essential. You’ll want treated or untreated wood that resists rot, mold and will last under outdoor conditions. 3) Plan and Cut Planter. The size of your finished planter is up to you. Use wood boards that are 5 to 10 inches wide. 4) Assemble Planter. The DIY planter box will have to be sturdy enough to hold plants and wet soil. It’s important that you fasten the boards together properly and securely. 5) Sand & Add Drainage Screen. Sand any rough edges on your planter box. If you’re considering a bare, natural wood look, give the planter an overall sanding. 6) Paint or Stain Planter Box. Protecting your DIY planter from moisture, mildew spores and UV damage will keep it looking its best. 7) DIY Planter Tips. Place your new planter in place and adjust the angle so that the box gets the correct amount of sun.
What type of wood is needed to build a planter box?
Pressure-treated pine is also commonly used to build planters, but it has some drawbacks that natural woods do not. Pressure-treated lumber is treated with chemical preservatives to make it rot, insect and weather resistant, but these are not ideal for planters that contain edible plants such as vegetables or herbs.
How deep to make a planter box?
Large bulbs require a planting depth of 8 inches, which means the planter box should allow for the 6 inches needed at the bottom, as discussed earlier, making the depth at least 14 inches. Most smaller bulbs are planted at 3 to 4 inches deep, so they would do fine in planter box with an 8-inch depth.
What wood to use for planter boxes?
The best wood for planter boxes is black locust lumber.
