Line your window boxes and planters to keep your plants and flowers thriving throughout the seasons. Planter box liners retain soil and nutrients, and can be integrated into your curb appeal design flawlessly. Manufactured from durable cellular PVC, our tapered line of planter inserts fit our Decora Wrought Iron Window Boxes. They are made with mitered corners and PVC is inherently rot, warp and mold-proof. In addition to fitting those cages, these liners can also be used as standalone planters, fence/wall planters or as railing planter boxes (purchase brackets). Drainage holes are pre-drilled to ensure your plants have a fighting chance to avoid overwatering, and additional accessories like self-watering reservoirs are available to lend a helping hand. Custom colors and lengths are available by request.
