Absolutely. When you order from our planter box factory, adding a trellis that attaches securely to the back is a standard customization we offer. Our design process prioritizes both aesthetics and structural integrity, ensuring the trellis integrates seamlessly with the planter’s frame without compromising stability.

For the attachment method, we typically use stainless steel brackets or concealed bolt systems that anchor directly into the planter’s reinforced back panel. This prevents wobbling even when supporting heavy climbing plants like tomatoes, cucumbers, or flowering vines. You can choose from several trellis styles: flat-panel wire trellises, wooden lattice, or powder-coated metal grids. Each option is pre-drilled and matched to your planter’s dimensions.

We also accommodate height adjustments. If your plants need extra vertical space, we can extend the trellis up to 6 feet (1.8 meters) with additional crossbars for climbing grip. All materials—cedar, composite, or corten steel—are treated for outdoor durability, and the trellis components are available in matching or contrasting finishes.

For larger orders or custom shapes (e.g., tiered planters with corner trellises), our engineering team can create a mounting blueprint that distributes weight evenly. We’ll even pre-assemble the trellis connections so you only need to tighten a few screws on site. Simply provide your planter size, trellis height preference, and desired climbing plant type, and we’ll tailor the integration accordingly.

If you’re concerned about shipping, rest assured: trellises are either shipped flat-packed with alignment guides or attached to the planter with quick-release pins, depending on the model. Contact our factory directly to discuss specific loads, wind exposure, or drainage integration—we can modify the design to match your local climate.
