What Type of Wood is Best for Planter Boxes?

If you’re interested in growing your own plants or vegetables but have limited space, raised planter boxes are the perfect solution. Not only do they provide a practical gardening space, but they can also teach children valuable life skills and encourage them to eat vegetables. It’s no wonder that garden boxes have become incredibly popular across the UK.

Raised planter boxes offer numerous benefits to both experienced and novice gardeners. They prevent soil compaction and erosion, improve water retention and drainage, and enhance the overall aesthetics of your outdoor area. However, choosing the right material for your planter box is crucial to avoid issues such as unwanted weeds, overheating, or rusting. And when it comes to materials, wooden planter boxes are the way to go.

Advantages & Disadvantages of the Most Common Wood Types

To help you make an informed decision, let’s take a look at the four best wood types for planter boxes: Cedar, Redwood, Pine, and Iroko. Each wood type has its own unique advantages and disadvantages.

Cedar

Cedar is a popular choice due to its durability, lightweight nature, and resistance to cracking. It has a Janka rating of 900 lbf and can last between 10 and 15 years. Cedar is also highly resistant to harsh weather conditions and pests. One of the best things about cedar is that it requires very little maintenance and doesn’t need to be stained or sealed. Over time, it may fade to a weathered grey, which some find attractive.

Redwood

Redwood is another excellent option for planter boxes, boasting a Janka rating of 3,190 lbf. It is readily available and naturally rot resistant. In fact, redwood can last up to 20 years with proper maintenance. Similar to cedar, redwood is low maintenance and not treated with chemicals. However, it is typically more expensive than other alternatives and requires sealing to prevent cracking.

Pine

Pine is a versatile and affordable wood option with a Janka rating of 1,630 lbf. It is lightweight, resists shrinking and swelling, and offers attractive grain options. However, it’s important to note that pressure-treated pine contains chemicals to preserve the wood. Pine is also susceptible to scratches and dents.

Iroko

Iroko is a less common wood type but offers its own set of advantages. It has a Janka rating of 1,260 lbf and is known for being durable, rot and insect resistant, and moisture-resistant. Iroko also has excellent heat moderation qualities and is renowned for its aesthetic appeal. However, it can be harder to find, comes at a higher cost, and requires more maintenance.
