Plastic Liners for Planters and Window Boxes

Standard plastic liners are an economical way to line your indoor and outdoor planters and window boxes. Made of a durable polypropylene material that will last a long time in wet environments, these white, green, or black options come with no holes in the bottom so they can be used indoors, or punched through pre-scribed holes for outdoor drainage. These polypropylene inserts are made in the USA. They are available in custom lengths upon request.

Lightweight & Durable, These Liners Deliver!

Poor solutions are flimsy and only last a season in the sun before they're discolored and damaged. Not the case with our poly-pro line. These are ultra-thick, long-lasting, and are fade-resistant. If you're searching for simple black options in popular sizes, check out our online collection. In this convenient shopping category, we feature polypropylene inserts to fit your indoor and outdoor window boxes and planters.

In colder climates, these units can be utilized to begin growing inside at the end of winter. Get a jump-start on the brilliance of spring simply moving them outside once everything is sufficiently thawed. At the other end of the planting season, the durable plastic allows for easy salvaging of late season growth. Once the earliest frosts hit, simply remove whole from window boxes, pop them inside for the night, and allow flowers to survive just a little bit longer.

Standard Sizes & Color Choices

Our standard sizes come in four different measurements including 18", 24", 30" and 36" long. All the inserts seen here measure 8" wide and 5" high. Smart sizing makes for an easy fit within most window boxes, deck box planters, railing planters or other flower boxes. Simply measure along the inside edge of the container you wish to line and choose the plastic liner best suited in size.

Dark color units absorbs most light - making them ideal for starting seedlings. Other UV protected hues like green and white are available, providing gardeners with the option to blend into their environment or boldly stand out. Polypropylene is a lightweight, resilient plastic material that will house plants efficiently and handle moisture impeccably.

You'll appreciate the ease with which this material benefits your gardening regime. When you don't have to worry about rotting, cracking or splitting, you can spend more time focusing on the beautiful flowers and plants adorning your home.
