When I tell people I need a planter box factory that stocks cedar options in unusual lengths like seven feet, the first reaction is usually a pause. Seven feet is not a standard dimension for most off-the-shelf planter boxes. Most retailers carry five-foot or six-foot cedar planters at best. But a dedicated factory that specializes in cedar can absolutely do this. In fact, an unusual length like seven feet is precisely the kind of custom request that a true planter box factory handles on a regular basis.
The key is understanding what “stocks cedar” really means. A factory with its own mill and lumber inventory will have access to rough cedar boards in extended lengths, often up to eight, ten, or even twelve feet. The reason most stores do not offer seven-foot planters is not a lumber limitation; it is a retail convenience limitation. Standard pallet sizes and shipping constraints make it easier for big-box retailers to stick to fewer, shorter SKUs. A planter box factory, by contrast, can cut and assemble precisely to your specification.
What you should look for in a factory is the ability to mill cedar to your exact requested length. That means they should be willing to take a standard eight-foot or ten-foot board and trim it down to seven feet, then construct a planter box using that continuous piece for the sides. This is far stronger than splicing two shorter boards together, and it creates a cleaner visual line, which matters when you are building a long, dramatic planter for a deck, a balcony, or a commercial landscape.
Another important consideration is the grade of cedar. Northern white cedar and western red cedar are both excellent choices for planters because they are naturally rot-resistant and hold up well against moisture. A good factory will let you choose between clear cedar (no knots, premium finish) and knotty cedar (more rustic, more affordable). For a seven-foot planter, clear cedar is often preferred because long, uninterrupted surfaces show off the wood grain beautifully. But if your design is more farmhouse or natural, knotty cedar adds character.
You may also need to think about the planter’s internal structure. At seven feet long, the weight of soil and water can be substantial, so the box should have reinforced corners, a center support brace, and a proper drainage system. Ask the factory whether they add a vertical divider or extra cross-bracing inside the planter. Some factories can also install a built-in liner or a false bottom to reduce soil volume and prevent overwatering. These are not standard features on short planters, but a custom factory can easily integrate them.
Shipping is the one real challenge. Seven feet is longer than typical parcel carriers accept, so the factory will likely ship via freight or a dedicated LTL carrier. Many factories are used to this and will package the planter in a sturdy wooden crate or wrap it in heavy-duty plastic with edge protectors. If shipping cost is a major concern, you can ask for a knocked-down or flat-pack version that you assemble yourself. That drastically reduces freight volume and sometimes makes seven-foot planters more affordable than buying a ready-made one.
What if you want the factory to simply sell you the seven-foot cedar boards so you can build your own planter? Most planter box factories can do that too, as long as you ask for “dimensional cedar stock” rather than a finished planter. This is a great option if you have a specific joinery method in mind or if you want to build a matching set of planters on site. Just be clear about your intended use so the factory can recommend the right thickness — usually 1.5 inches for side walls and 1 inch for the bottom slats.
One thing I always recommend is ordering a sample or a small test piece before committing to a full seven-foot production run. Because the length is unusual, you want to confirm the wood quality, color, and finish in person. A reputable factory will happily send you a small cedar sample or even a miniature scale model of the planter. This costs a little extra but saves you from potential disappointment.
When you contact a planter box factory, use precise language. Instead of asking “Do you have seven-foot planters in stock?”, say “I need a planter box factory that stocks cedar options in unusual lengths like seven feet. Can you mill and assemble a seven-foot planter with continuous side boards?” This immediately signals that you know what you are talking about and that you expect custom work. Most experienced factories will answer, “Yes, we absolutely can do that.” And if they hesitate, that tells you they are not the right partner for your project.
So yes, a planter box factory can handle your seven-foot cedar request. The trick is finding one that controls its own lumber supply, embraces custom cutting, and has the structural wisdom to build for extended lengths. When you find that factory, you will get not just a planter, but an heirloom-quality piece of garden architecture that fits your exact space. Do not settle for a store-bought compromise. Go straight to the source and let them craft the seven-foot cedar planter you actually need.
