Your window will seem to smile when you mount this planter box on the outside. The Mayne 36-Inch Rectangle Polyethylene Fairfield Window Box features an attractive double-frame exterior with decorative molding on the top and bottom. This window box planter is designed with an innovative sub-irrigation system, which reduces the frequency of watering by storing water in the base of the planter. The built-in water reservoir encourages healthy plant growth by allowing roots to absorb water as they need it from troughs in the bottom of the planter. That means you"ll spend less time tending your plants and more time admiring your blooms. This planter is finished on all sides so you can even place it on your patio or porch. This attractive rectangular planter is made of high-grade polyethylene, which is a durable, low-maintenance material for all-season use. The planter looks like wood but requires none of the maintenance that outdoor wood planters need, such as painting and re-sealing. The planter comes with wall mount brackets that attach it to the outside of your window. If you wish to mount the planter on a deck rail, you will need to order a deck rail kit, which is sold separately.
