In this article, we will be teaching you to make your very own wooden window flower box. This DIY tutorial will be using a basic rectangular design which is versatile for different applications. Here are the needed materials and steps to build a window flower box :
What you need for building a window flower box
- 1 inch thick wooden boards (Cedar or Cypress are the best options, size will depend on the length of your window box)
- 2 x 4 lumber
- ¾ “ galvanized crews
- ¼ “ galvanized nails
- Paint or wood stain
- Sand paper
For planting flowers and plants in a window box
- Potting Mix
- Crocks or crushed terracotta pots (if planting directly in the window flower box)
- Nylon or Vinyl Screen (to be used as a liner for the window flower box, serves the same purpose of crocks, so if using crocks there is no need for this and vice versa)
- Pots (if you do not want to plant directly on your window flower box)
What to Use:
- Measuring tape
- Electric drill
- Saw or electric saw
What to Do:
• Measure your window. Using a tape measure, accurately measure the width of your window to determine the length of your window flower box. Measure from end to end of the window trim and frame. For the depth and height of your window flower box, make sure that it is large enough to accommodate your flower pots and planters (if using any). If your window flower box will be resting on a ledge, you also need to get the depth of the ledge.
• Cut and trim the boards according to desired length. Measure the boards and using a pencil mark the lengths of the panels of your window flower box. You will be needing a total of 5 pieces of boards, 1 for the front panel, 1 for the back panel, 2 side panels and 1 bottom board. You can do this yourself or you can ask your supplier to cut it for you.
• Cut the brackets. Using a template, mark a piece of your wooden board and cut it according to shape using a circular saw. Ideally 3 brackets are used – one for each side and one in the center, but this will vary depending on the total length of your window flower box. If planning on attaching your window flower box to the sidings of your house, make sure to put notches. Aside from wooden brackets, you can also use ready made L-shaped brackets or anchors to mount your window flower box. Just make sure that it can support and carry the load of your window box, as well as the extra weight it may incur when watering.
• Attach the front and back panel to the side boards. Using an electric drill, drill three pilot holes on the front panel and the end of the side panel, overlapping each other to form a 90 degree angle. The pilot holes must be equally spaced and at least ¾ inches from the edge of the boards. Fasten boards together using a screwdriver or electric drill and some galvanized screws. Repeat the same process for the back panel and the other side panel. Then fasten all boards together to form a box.
• Attach the bottom board. Once all side panels are complete, attache the bottom boards using galvanized screws and a screwdriver or electric drill.
• Drill drainage holes. Flip your window flower box over and punch 4 to 5 drainage holes on the bottom board with the use of an electric drill. A minimum diameter of ½ inch is the ideal size for drainage holes.
• Add finishing touches to the window box. Using a sander or sandpaper, smoothen all edges your window box and apply paint or wood stain as finish.
• Attach brackets to the window or wall sidings of the house. Position brackets where the support is needed – one at each end and one in the middle. Make sure that it is properly aligned and attach brackets to the house interior using screws and an electric drill.
• Secure window flower box. Place the window box on top of the brackets.
• Fill the box with flowers and plants of your choice. If planting directly on your window flower box, insert a piece of vinyl or nylon screen and make sure to drill pilot holes on them too. Or rather than using a liner, you can use “crocks” and fill your plant box with crushed terracotta pots at the bottom. Add potting mix keeping the plant box at least ⅔ full then plant flowers according to desired arrangement. Do not pack the plants to tightly.
Some additional tips when building your own window flower box:
• The typical depth and height of window flower boxes is usually 6 to 8 inches, but this varies.
• Window flower boxes are commonly mounted 6 to 8 inches below the sill to leave clearance for the plants.
• In choosing the type of wood for your window flower box, use wood species which are resistant to water damage as these containers are constantly exposed to outdoor elements. Wood is also naturally prone to insect damage and rotting, so make sure to choose something which is resistant to these factors. Cedar and Cypress are the best options because they are both resilient when wet and weather, rot and insect resistant.
• Choose the right type of mounting hardware for your window flower box. This will depend on the house’s’ exterior facade materials. Avoid expandable anchors for bricks because they cause it to break. Use large anchors for plywood, wood and stucco.
• Always use galvanized or rust proof nails and screws.
• Drainage holes are very important. Never skimp on drainage holes because it keeps the soil well drained. If your soil is too wet, plants have the tendency to develop diseases such as “soggy feet”. Punch enough holes on DIY planter boxes or if going with store bought options, make sure to check them before purchase.
• If planting directly on your window flower box, use a layer of “crocks” to prevent drainage holes from clogging up and to stop the soil from falling out.
