Planters filled with flowers and plants can make a strong statement. You can use them to spruce up an area, decorate a porch, bring landscaping to the interior, or just to add some curb appeal to the front of your house. Wood planters are something that you can learn to build and will work perfectly for you. This way you can custom make them the necessary size to meet your needs. This article will cover step-by-step instructions for building your own wooden planters.
Step 1: Purchase cedar planks from a local lumber dealer. Cedar is usually readily available and comes in planking that is 7.25" wide in most locations. 3/4" is a good thickness for cedar to be both durable and resist rotting the longest. Cedar is a good wood to build wooden planters from because it can naturally resist rotting, allowing your planter to last an average 5-7 years. Other woods such as pine can deteriorate quickly in water prone applications and are less than ideal for building wooden planters.
Step 2: Cut the end pieces first. This can be done by cutting the board at 9.75" (7.25" bottom + 3/4" front + 3/4" back).
Step 3: Cut the front, back, and bottom next. Cut the board at the desired length of the wooden planter box three times, but subtract 1.5" from the measurement to account for the side pieces. These three boards will be glued and screwed together to form a "channel", or gutter shaped trough.
Step 4: Apply a wood glue to the surface where the boards meet and drive a 2" deck screw between the front board and the bottom board where they join. You can use a countersink drill bit and plug cutter to pre-drill holes where the screws will go and make your own plugs to cover up the screw heads afterwards if you want a more professional finish. The screws will work like clamps to hold the boards together while the glue sets. Make sure to wipe off any excess glue.
Step 5: Attach the side pieces with screws and glue also.
Step 6: Caulk the inside joints to form a water tight barrier. You can use a clear silicon here. Prime the outside and inside of the window box as well. Cover the wooden planter with 2-3 coats of the desired paint color. You can use a brush and roller here. An exterior latex paint works great for outdoor applications.
Step 7: Place a plastic liner inside your wood planter. To help prolong the life of wood, its best to keep it out of contact with dirt, insects, and water. You can also sit half gallon pots inside. For larger wooden planters you make wish to use wider boards.
Voila! Learning how to build and make your own wooden planters is easy. Remember these simple steps and you won't have any problems.
