Add a Colourful Window Box

If you have a small garden or only a balcony, adding a window box is an easy way to add colourful plants to add a splash of interest to your home and your outdoor space.


Making a window box is a quick and easy project that you can most probably knock up in a day, or a spare weekend, and there are plenty of different designs to choose from to make your own window box; from a basic plywood box, to a more formal design that features decorative panels and brackets.





You also have the option to choose the material for making your window box, with plywood and pine being the most affordable options, but also options that require regular, ongoing maintenance, or more expensive materials such as marine plywood and hardwood (Meranti, Saligna, etc.) that don't require as much maintenance.

Select annual, perennials or small plants according to the position where the box will be mounted onto a wall or windowsill. Your local garden centre will be able to offer advice on the best plants suitable and how to care for these once planted up. Do bear in mind that all container plants require regular watering, especially when the weather is hot and dry.

Some plants love being planted in window boxes and thrive in this setting. Annuals love a sunny spot and Geraniums come in  all varieties and colours and are excellent for adding colour to a windowsill.



How to make a Window Box

Whatever material you choose to work with, making a window box is an easy project.


1. Cut all your timber or plywood to the correct size (length, width and height) to fit inside or below the windowsill. Also take into consideration the size of the planter box that will fit inside the window box frame.

2. Use exterior wood glue and 40mm screws to assemble the box. This is a basic box design and you can cut a base to fit inside the box frame or cut a base on which the box frame sits - whichever is easiest for you.

3. Once assembled, drill holes in the base to allow for drainage, or staple a waterproof liner inside  the box frame if you are keeping the tray on the base of the planter box. The last option is the preferred choice as it helps preserve the timber for longer.

4. Once the box is made you can apply your choice of finish for detail. This is entirely optional but does add that extra bit of something to a window box.

Pop into your local nursery or garden centre to select the right plants for your new window box. Annuals and perennials make a wonderful display when planted up, and you can add a few hanging plants that drape over the edge of the window box to soften the hard lines.
