Why Use Planter Box Liners
Flower window boxes add curb appeal to your home. And for some, they allow you to enjoy flowers and plants when faced with limited planting space.
Unfortunately, they can deteriorate from the moisture conditions inside the planter—for example, metal flower boxes rust.
Wood flower window boxes rot. The beneficial organisms in the soil break down the wood and increase its decay rate. So, you may have to replace them every year.
Planter box liners help extend the life of your planters by preventing direct contact with the soil, organic materials, and water inside your flower window box. Your planter box stays dry regardless of how often you water.
Flower Box Liners Make Planting Easier
Planter box liners let you pot your plants outside of the planter box. So you can move plants around easier. And you don’t have to worry about your potting mix falling out of the flower window box and making a mess as you move pots around.
Just insert the flower box liner into your planter when you're finished planting. The liners also make it simple to move your plants from one location to another. Or to switch plants seasonally. For example, keep your bulbs inside the planter box liner after spring and use another liner to change to summer blooms.
Plastic Liners Prevent Leaching
Poly-Pro flower box liners are constructed from a superior plastic blend. Plastic isn’t permeable. So you won’t have to worry about moisture leaching into your planter.
Equally important, plastic prevents any chemicals in treated wood planter boxes from harming your plants. That’s especially important if you use your window flower boxes to grow herbs or vegetables.
Poly-Pro Flower Box Liners Can Be Used as Standalone Planters
Our liners also feature distinctive ridged panels to ensure ruggedness and sustainability. As a result, you can use these versatile planters as planter box liners or standalone planters. When used alone, built-in feet provide proper airflow and reduce the chance of water pooling under the planter.
You can use Poly-Pro planter box liners indoors or outdoors. When used outdoors, you can punch or drill the holes on the bottom of the planter for proper water drainage.
Our planter box liners are lightweight and recyclable. They’re also UV-protected to resist fading. And they’re proudly made in the USA.
Available in three colors, you can select from 18”, 24”, 30”, and 36” flower box liners to fit almost any sized planter.
How should I pot my plant?
Add a small amount of perlite medium on the bottom of the flower box. Finish filling with a light to medium weight potting mix. Routinely adding plant food, according to plant’s directions, will dramatically increase the health, beauty and longevity of the plants in your Poly-Pro Flower Boxes.
