When it comes to gardening, one material reigns supreme: Western Red Cedar. Thanks to its unique natural properties, cedarwood is the ideal choice for planter boxes and raised garden beds. And while there are countless cedar products on the market, many handy gardeners choose to build their own DIY planters is a fun weekend project.

In this guide to cedar planter boxes, we'll cover everything you need to know about the material and recommend a few cedar planters to add to your yard this gardening season.

What is a cedar planter box?

Cedar planters are made using wood from Western Red Cedar trees native to North America. It's lightweight, durable, and resists cracking with little to no maintenance and upkeep, making it a popular choice for gardening supplies. Plus, it smells incredible!

What makes cedar wood good for planter boxes?

The wood used in planters needs to not only look good but to last. Here are a few characteristics that make cedar one of the most popular choices for planter boxes:

  • Naturally Repels Bacteria, Fungi, and Insects— While other wood planters require treatments and sealants to prevent rot and stop insects, cedar is naturally resistant to bacteria and fungi.
  • Thermally Coefficient— Cedar naturally stays cool, helping keep plant roots at a stable temperature in hot, humid weather.
  • Durable and Long-Lasting without Much Maintenance— Thanks to its natural oils, cedar ages well, resists cracks, and requires little maintenance.

How long do cedar planter boxes last?

If you're going to shell out a few hundred dollars on a new planter box or take the time and effort to DIY your own from a few boards, you'll want to be sure you choose materials that are built to last. Thanks to its bacterial- and rot-resistance and natural oils, a cedar planter box can last upwards of 10-15 years with proper care. During this time, you'll likely need to replace a few worn-out liners and refresh the planter with new soil to keep it looking its best.

It's important to note that the life of a planter box depends widely on location, use, and care. Factors like sun, wind, climate, and how you care for both your plants and soil can all affect how long your planter lasts. Additionally, treated wood typically lasts longer than untreated wood thanks to the addition of rot-, insect- and water-resistant chemicals.

Do raised garden beds made from cedar need to be lined?

Whether or not you line your cedar planter box is up to you. While an untreated cedar box will fare just fine without a lining, using a plastic liner or landscaping fabric may help it to last longer.

When lining a planter, it's crucial to use non-toxic materials. In addition, to keep water from building up inside the container, you'll need to be sure the liner has holes or create an adequate drainage system to prevent rot and disease.
