Get more from your window boxes and planters with these simple and functional liners. Originally only offered in black, we now offer our standard plastic liners in white and green. They're inherently colored, so there is no concern of the finish ever chipping off. Since darker colors absorb more UV rays and conduct more heat, green and black plastic liners are a great choice for starting seedlings. Our classic white color reflects the sun's rays and is great for sunny areas, and in locations where the liner will be seen.

There are many perks to using a liner with your coordinating window boxes. They're easy to remove, which makes cleaning, replanting, or switching out seasonal faux flowers quicker and easier. It also makes it possible to move flowers from one setting to another in order to ensure every arrangement gets its fair share of time in the sun, or to take plants indoors when the weather turns unexpectedly colder than anticipated. Additionally, their spacious interior has plenty of room for any plant life you have in mind. From herbs outside the kitchen window or lush flowers that bloom for all to see, your gardening options have opened up wider than ever before.

These polypropylene (poly-pro) liners are made from highly durable plastic materials that won't rot or warp like wooden liners and boxes can, so you can rest assured they'll hold up against wear and tear, even when used in inclement outdoor conditions.

Drop them in existing planters, or use them as standalone garden boxes. Place atop dividing walls, or mount along railings and building exteriors (purchase additional brackets). These liners are not available in custom sizes, but we do manufacture custom liners in other materials. Shop online or call toll-free to discuss your options: 1-800-896-0978
