Autumn is the ideal time to plant a window box. Fill it with vibrant winter-flowering annuals or spring-flowering bulbs
and you’ll have a world of colour right outside your window. It’s the perfect way to appreciate your garden without having to venture outside in cold weather.
Things to consider before you begin:
To get started, you’ll need:
- Is the windowsill you have in mind broad enough to support a window box? If not, install a bracket just beneath the window.
- Bear in mind the way in which your windows open and close. You’ll need to choose plants that won’t block this movement.
Here’s how to plant your window box:
- A window box
- Weed-control fabric or a thin dishtowel
- Potting soil
- Water-retaining crystals and slow-release fertiliser
- Plants of your choice
- Hand shovel
- Line your window box with weed control fabric or a thin dishtowel. This will allow water to drain through the bottom of the box, but will keep the soil inside.
- Fill the box with potting soil. Add water-retaining crystals and slow-release fertiliser and mix together.
- Plant a selection of winter-flowering plants like pansies, primulas, violas, daffodils and pelargonium or spring-flowering bulbs like ranunculus, sparaxis, dahlias and Cape cowslip. A kitchen window could also be the perfect place for a pretty herb box filled with chives, parsley, thyme and rosemary.
- Pat down the soil, ensuring it is about 2cm below the brim of the window box. This will prevent overflowing when you water your plants.
- Water every second day and look forward to a pretty display in the months to come.
