How to Create Gorgeous Window Boxes

In this community interest article, we explain how to create window boxes that will transform the exterior of a property.


You don’t need to be an expert gardener or have lots of space to create cheery window boxes that are the envy of all your neighbours.

All it takes to create a spectacular display that gives your home instant kerb appeal is a windowsill big enough to accommodate a planter box and a little bit of imagination.

Choosing your plants

Your window box can be as simple or complex as you like depending on your personal taste and gardening know-how. (Check out Pinterest if you’re looking for inspiration.)

Some people choose one type of flower or plant, while others opt for three or four varieties in varying colours and textures to create a more elaborate display.

One key thing to consider is how much sun your window ledge gets throughout the day and to plant species that will thrive in these conditions.

Sun-loving plants include petunias, salvias and lavender, while shade-loving varieties include ferns, cyclamens and orchids.

Good enough to eat

If flowers aren’t your thing, plant chillis, tomatoes or strawberries instead or create a mini herb garden by planting parsley, mint, basil and thyme.

Watering

Window boxes can dry out quickly, so water regularly. If you’re unsure if your plants are thirsty, dip your finger in the compost. If it feels dry, give them a soak.

Types of planters

You can get window boxes made from wood, terracotta, metal or plastic. If you opt for a wooden window box, improve its longevity by giving it a coat of moisture-protecting sealant and placing a plastic liner inside before adding potting soil.

Also, check your window box has holes in the bottom, as these will allow excess water to drain away; this will minimise the chance of your plants developing root rot.

General upkeep

Keep your plants well-fed by adding liquid fertiliser every week or so. (Note: some fertilisers smell worse than others, so have a sniff before you buy.)

When the blooms on your plants start to wilt, cut them off; this is called deadheading and will encourage more flowers to grow.

And, if you spot any pests, act quickly; once insects get into a confined space such as a window box, they can run riot.
