Step-by-Step Guide to Building a Raised Planter Box
Step 1: Plan Your Design
Before starting, decide on the size and shape of your planter box. Common dimensions for a raised planter box are 4 feet long, 2 feet wide, and 1–2 feet high, which provide ample growing space while being easy to reach.
Step 2: Cut the Wood
Measure and cut the wood planks to your desired dimensions. You’ll need pieces for the four sides and the base. Sand the edges for a smooth finish.
Step 3: Assemble the Frame
Using screws or nails, join the planks together to form a rectangular frame. Ensure the corners are square for stability.
Step 4: Attach the Bottom Panel
Secure the bottom panel to the frame, leaving small gaps or drilling holes for drainage. For extra durability, use exterior-grade screws.
Step 5: Line the Box
Line the interior with landscape fabric to prevent soil from leaking and to protect the wood from moisture.
Step 6: Apply a Protective Finish
To extend the life of your planter box, apply a weatherproof sealant or wood stain. This is especially important if you’re using untreated wood.
Step 7: Fill with Soil
Add a layer of gravel or small rocks for drainage, followed by high-quality potting soil or compost.
