How to Build a Window Planter Box

To elevate your home’s curb appeal, nothing beats the charm of a stunning window flower box that transforms with the seasons. By following our comprehensive guide, you’ll learn how to craft durable and attractive window boxes from PVC material, renowned for its longevity and resistance to rot. With step-by-step instructions inspired by the expertise shared in ‘Ask This Old House,’ you’ll be well on your way to creating a beautiful display that will impress your neighbors and add value to your property.

Gathering Your Materials

When it comes to building your window boxes, you’ll want to start by gathering the essential materials. Begin with a 1×10 PVC stock, which will form the foundation of your design. For added flair, select some band molding and base cap for decorative trim. To ensure everything stays in place, have on hand two-part PVC glue for bonding, as well as stainless trim head screws (2.5 inches long) and structural screws (4 inches long). To bring your vision to life, you’ll also need a saw for cutting the PVC, a drill with a half-inch spade bit, and right angle attachment, along with brad nails for added support.

Construction Steps

To create your window boxes, start by accurately cutting your 1×10 PVC stock into the required dimensions. Ensure a seamless finish by mitering all corners at a precise 45-degree angle. Next, employ the two-part PVC glue to bond the mitered corners together, reinforcing the joints with brad nails in the center. Then, drill and screw the front, back, and sides together using 2.5-inch stainless trim head screws for a sturdy construction. Once the main frame is assembled, measure, cut, and attach the bottom piece of the box to achieve a snug fit. To complete the structure, add decorative flair by applying band molding across the top and base cap (flipped over) along the bottom. Finally, drill weeping holes every six to eight inches at the bottom using a half-inch spade bit to prevent waterlogged plants.

Mounting Your Window Box

To effectively install a window box, start by determining its precise placement under the window. This involves locating the studs inside the wall, which will serve as anchors for securing the box. Once you’ve identified these structural elements, transfer the mounting hole positions from the wall to the back of the window box and pre-drill them to create a stable foundation.Next, ensure a watertight seal around the screws by applying caulking to each pre-drilled hole before securing the box. Use 4-inch structural screws to attach the window box to the wall, double-checking that it’s level and firmly in place.


To create a thriving indoor garden, start by selecting a diverse mix of perennials and annuals that will flourish in the sunlight available from your window. When preparing the container, begin by lining the drainage holes with landscape fabric to prevent soil erosion. Next, add a layer of volcanic rock for improved air circulation and top it off with potting soil. Once the box is ready, arrange your plants according to their height and visual appeal before planting them in their designated spots. Make sure each plant has enough space to grow and is planted at the correct depth in the soil. Finally, give your new flowers a good soaking and establish a routine of regular watering and fertilization every three months to promote healthy growth.

DIY Window Planter Box FAQs

Embarking on a DIY window planter box project can be an incredibly fulfilling experience. To guarantee its success, we’ve addressed the most frequently asked questions, providing valuable insights to guide you through each stage of the process.

What materials do I need to build window planter box?

To create a fundamental window planter box, you’ll require the following materials: A durable and rot-resistant lumber option like cedar is recommended. Additionally, you’ll need a saw for cutting wood to size, a drill for making holes, screws or nails for assembly, and an optional can of wood glue. For finishing touches, sandpaper will help smooth out any rough edges, while paint or stain can add a pop of color if desired. To prevent weeds from growing up through the box, consider lining it with landscape fabric. Finally, you’ll need potting soil and your chosen plants or flowers to bring the planter to life.

How do I ensure my window box has proper drainage?

For a healthy and thriving window box garden, it’s essential to prioritize proper drainage. Waterlogged soil can be detrimental to your plants’ well-being. To achieve optimal drainage in your window box:

Start by drilling multiple evenly spaced holes in the bottom of the container.
Next, cover these openings with a layer of landscape fabric to prevent soil from escaping during watering or rain events.
As an added measure to enhance drainage, consider adding a thin layer of gravel or small stones beneath the soil. This simple modification can make all the difference in maintaining a happy and healthy garden.

Can I attach a window box without drilling into my home?

While drilling-free attachment options do exist, there are a few ways to secure a window box without compromising the integrity of the surrounding material. For instance, adjustable brackets that protrude over the window sill provide a sturdy base for your planter. Alternatively, no-drill hooks specifically designed for window boxes can be attached to the frame itself. However, it’s crucial to consider the weight capacity and wind resistance of these methods when selecting an attachment approach. Be sure to choose a solution that can safely support the weight of your window box when filled with soil and plants.

What plants are best for a window planter box?

When it comes to choosing the perfect plants for your window box, the amount of sunlight it receives is a crucial factor to consider. Here’s a breakdown of the best options based on the level of sunlight:

For windows that receive full sun, petunias, geraniums, marigolds, and zinnias are great choices, showcasing vibrant colors and lively growth.

Partial shade is ideal for impatiens, begonias, fuchsia, and coleus, which thrive in conditions with some indirect light. These plants will add a pop of color to your window box without demanding too much attention.

If your window box receives little to no direct sunlight, consider planting ferns, hostas, or heuchera – these shade-loving options will still bring beauty and texture to the space.

To create a visually appealing display, don’t be afraid to mix and match different plant types, including trailing plants that cascade over the edges, tall plants that provide structure, and colorful foliage that adds depth and interest.

How do I maintain my window planter box?

To keep your window planter box thriving, follow these essential care tips: Regular watering is crucial, ensuring the soil’s moisture level stays just right – not too dry, nor waterlogged. Fertilize your plants according to their specific needs, providing them with the nutrients they require to flourish. Keep an eye out for spent flowers and deadhead them to stimulate new growth. Monitor your plants for any signs of pest infestation and take action as needed to prevent damage. If you opted for a wooden planter box, schedule annual inspections to detect wear or damage, and reapply paint or stain as necessary to preserve the wood’s integrity.

Can I build a window box if I’m new to woodworking?

For those just starting out, there’s good news: many simple designs are perfect for beginners. To get started, create a basic plan and don’t be afraid to seek guidance or additional help from your local hardware store. The process of building a window box can be an excellent way to develop your woodworking skills, and it’s a great opportunity to make mistakes while learning.
