This unit combines a garden arch trellis with planter boxes so the growing container and the climbing structure arrive as one piece rather than two purchases that have to be lined up on site. The watering system is what makes it low-maintenance: a reservoir with a siphon design draws moisture up to the roots gradually and reduces watering frequency, while drainage holes fitted with plugs let excess water out and prevent water accumulation that would otherwise rot roots in a sealed box. Each planter box measures 14.5 by 14.5 by 17.5 inches inside, and the boxes are extendable, making them suitable for growing a variety of plants.The climbing structure works on three surfaces. Two side trellises encourage climbing plants to grow upward instead of sprawling, and a classic arch top spans the gap overhead, which is equally suitable for displaying vines or balloons. Twenty zip ties are included to securely support plants for healthy growth as they establish.Materials are picked for sitting outside season after season. Rust-proof PE-coated metal pipes form the frame, and the coating also shields plants from high temperature by keeping bare metal from heating in direct sun. The panels are premium PP faux rattan, which holds up well and elevates the overall look beyond plain tube framing.The assembled frame measures 80 by 16 by 91 inches with a 58-inch entry width and weighs 19.5 pounds. Four universal wheels ensure effortless movement and a solid stay once positioned. Simple assembly requires no tools, and 20 zip ties plus a user guide are included.
