If you’ve already learned what composite decking is made of and whats a composite material, then you know that it can be useful for a number of things. One of these things is building planters.

You can create planters in different sizes to accommodate everything from small succulents to larger shrubs. The variety of colours available in composite decking adds a vibrant touch to your garden, harmonising with your outdoor aesthetic without the need for painting.

For those with limited space or who prefer a more tiered approach to their greenery, constructing a tiered plant stand is an excellent alternative, allowing for a charming display of various plants in a compact form.

Outdoor Shelves

Outdoor shelves crafted from composite decking are not just stylish but also remarkably practical. They offer a unique way to display plants and other kinds of outdoor decor. If placed near seating, they could even be used to place drinks.

Floating shelves, in particular, are a modern and minimalist option that is surprisingly easy to install. They can be a focal point in your garden or patio, providing an accessible way to add depth to your outdoor space.

Storage Chest

A storage chest made from leftover composite decking isn’t just a stylish addition to your garden; it's a practical solution for outdoor storage needs.

Ideal for storing deck accessories, blankets, or pool decorations, these chests are robust and weather-resistant. Adding padded cushions to the top transforms them into comfortable seating options, perfect for those summer cookouts or as a cosy nook to enjoy your garden.

Garden Edging

Garden edging is another brilliant use for leftover composite decking. It's an excellent way to define the borders of your flower beds or vegetable garden, adding a tidy look to your outdoor space.
