This 2 pack of 30 inch preformed coco liners provides a ready fit for trough and railing planters while supporting healthy root growth and easy planting. Key benefits Size and fit: Each liner measures 30 x 7 x 7 inches and is shaped to match square trough and railing planters, using planter space efficiently and allowing roots to spread. Natural material and strength: Made from natural coconut fiber with uniform thickness, the liners are solid and sturdy enough to hold potting soil and plants without tearing or sagging. Moisture management: Coco fiber holds moisture to keep soil hydrated longer while still allowing airflow and drainage so excess water can escape and soil does not remain waterlogged. Simple installation: Liners arrive compressed and folded. Soak briefly to help restore shape, unfold and press into place, add soil and plants, and water as needed. Liners can be trimmed with scissors to fit nonstandard planters. Practical details: You may notice slight stickiness when first opening a liner. This is a natural attribute that helps the liner conform to the planter and will dilute over time with watering. Specifications Quantity: 2 liners per pack Size: 30 x 7 x 7 inches each Material: Natural coconut fiber Shape: Preformed square trough liner compatible with railing and window box planters Use scenarios Balcony railing planter: Line a 30 inch railing trough, add potting mix and seasonal flowers to create a low maintenance display. Window box herbs: Fit a liner inside a window box, add herb seedlings and soil for a convenient indoor or outdoor kitchen garden. Patio or porch trough: Use as a liner for a decorative planter on a patio or porch to keep soil contained and improve planting depth. Notes Product ships compressed; soaking helps restore the original shape before installation. Trimming with scissors allows for slightly different planter sizes.
