How to Build a Window Planter Box

Making stunning window flower boxes can enhance the curb appeal of your home, offering a beautiful display that changes with the seasons. In this guide, based on the expertise shared in "Ask This Old House," we outline the process for building durable, attractive window boxes from PVC material, which is known for its longevity and resistance to rot. Let's dive into the step-by-step instructions to bring this project to life.

Gathering Your Materials

PVC Stock: Obtain 1x10 PVC stock for constructing the bulk of your window boxes.
Trimming Materials: Pick up band molding and base cap for decorative trim.
Fasteners: Have on hand two-part PVC glue for bonding, stainless trim head screws (2.5 inches long), and structural screws (4 inches long).
Tools: You'll need a saw for cutting the PVC, a drill with a half-inch spade bit, a right angle attachment, and brad nails.

Construction Steps

Cut to Size: Begin by marking and cutting your 1x10 PVC stock to the desired dimensions of your window boxes. Remember to miter all corners at a 45-degree angle for a cleaner look.
Assemble the Box: Use the two-part PVC glue to bond the mitered corners together, reinforcing with brad nails in the center of the joints. Then, drill and screw the front, back, and sides together using the 2.5-inch stainless trim head screws.
Attach the Bottom: Once the main frame is constructed, measure, cut, and attach the bottom piece of the box, ensuring there's a snug fit.
Add Decorative Trim: Apply the band molding across the top and the base cap (flipped over) across the bottom for an elegant finish.
Drill Drainage Holes: To avoid waterlogged plants, drill weeping holes every six to eight inches at the bottom using a half-inch spade bit.

Mounting Your Window Box

Determine Placement: Decide on the exact position under the window. Locate the studs inside the wall to secure the box to.
Pre-drill Mounting Holes: Transfer the mounting hole positions from the wall to the back of the window box. Pre-drill these locations.
Apply Caulking: Before securing the box, apply caulking to each pre-drilled hole to make a waterproof seal around the screws.
Secure the Box: Using the 4-inch structural screws, attach the window box to the wall, ensuring it's level and firmly attached.

Planting

Select Your Plants: Choose a mixture of perennials and annuals that thrive in the sunlight your window receives.
Prepare for Planting: Line the box with landscape fabric over the drainage holes, add a layer of volcanic rock for aeration, then top with potting soil.
Arrange and Plant: Position your plants according to height and visual appeal before planting them. Ensure each plant is properly spaced and seated at the correct depth in the soil.
Water and Care: Give your newly planted flowers a thorough watering. Going forward, maintain moisture levels and fertilize every three months for sustained growth.
