Yes—we do. From our planter box factory, we manufacture several cedar options designed to resist rot far longer than untreated pine or common softwoods. The best-performing choice for most outdoor planters is western red cedar. Its heartwood contains natural extractives that help it stand up to moisture, insects, and fungal decay. We can supply clear vertical-grain western red cedar for a clean, premium look and tighter, more uniform grain, or tight-knot cedar for a more economical rustic style. Northern white cedar is another strong option; it is lighter, naturally decay-resistant, and works well for larger boxes. For a higher-end natural finish, yellow cedar can also be considered, though western red cedar remains the most popular rot-resistant cedar for planter boxes.

No wood is completely rot-proof when it stays wet, so our factory builds cedar planters with longevity in mind. We recommend using heartwood boards rather than sapwood, choosing a thicker profile for structural strength, and assembling boxes with stainless steel or hot-dipped galvanized fasteners. Our standard designs include drainage holes, raised feet or an air gap, and optional liners or drainage trays to keep soil from sitting directly against the wood. We also seal end grain and can pre-finish with a plant-safe, water-repellent coating.

If you want a cedar planter box that will not rot quickly, tell us your size, climate, plant type, and expected lifespan. We can recommend clear western red cedar, tight-knot cedar, northern white cedar, or a custom blend, then produce it in our factory with the right drainage and protection details. Cedar will still weather naturally over time, but with proper design it can remain strong and attractive for many seasons instead of failing in a year or two.
