What is the best timber for outdoor planter boxes?

When it comes to choosing the best timber for outdoor planter boxes, there are several options to consider. Treated pine, cypress pine, jarrah, and cedar are all popular choices due to their durability and resistance to weathering. Each of these timbers has its own unique qualities that make them suitable for use in planter boxes.

Treated pine is a commonly used timber for outdoor applications due to its affordability and availability. It is treated with chemicals to protect against rot and insect damage, making it a long-lasting option for planter boxes. Treated pine can be easily found at most hardware stores and is relatively easy to work with.

Cypress pine is another excellent choice for outdoor planter boxes. It is naturally resistant to decay and termite attack, making it a low-maintenance option. Cypress pine has a beautiful grain pattern and a natural light brown color, which can add a touch of elegance to your garden or patio. This timber is often used for outdoor furniture and decking as well.

Jarrah is a hardwood timber native to Western Australia and is known for its exceptional durability and resistance to decay. It has a rich, deep red color that can add warmth and character to your outdoor space. Jarrah is a dense timber, making it highly resistant to rot and insect damage. While it may be more expensive than other options, its longevity and natural beauty make it a worthwhile investment.

Cedar is a popular choice for outdoor planter boxes due to its natural resistance to decay and insect damage. It has a distinctive aroma and a beautiful reddish-brown color that can enhance the visual appeal of your garden. Cedar is lightweight, making it easy to work with, and it has excellent dimensional stability, meaning it won’t warp or twist over time. While it may be pricier than other timbers, its durability and natural resistance make it a top choice for outdoor applications.

When constructing planter boxes, it is important to consider the type of timber cladding used for the side panels. Ship-lap profile cladding, available in either a sawn or dressed finish, is a popular choice. This type of cladding provides a clean and seamless look, while also offering structural stability to the planter box. It is readily available and can be easily installed by overlapping the boards to create a secure and weather-resistant barrier.

The best timber for outdoor planter boxes depends on your budget, desired aesthetic, and level of maintenance. Treated pine, cypress pine, jarrah, and cedar are all excellent choices due to their durability and resistance to weathering. Consider the specific qualities of each timber and choose the one that best suits your needs and preferences.
