Plant grand container garden arrangements in the XL Panel Flower Boxes. This oversized window planter is made of composite PVC with a matte white finish. And with a look indiscernible from painted wood, gardeners can still enjoy the classic charm of a wooden paneled design. Our 48" long flower planter features two panels across the length of the box for ultimate design impact.

Composite cellular PVC planter boxes are weather and insect resistant. The material will not rot, warp or crack, even in extreme temperatures, and your soil, plants and flowers can be potted directly inside - no liner required. A system of "Easy Up" Cleat Mounts makes this container simple to attach to most any exterior wall. Also allows for convenient take down and storage as needed.

Please note this product is an Extra Large Garden Container with extended width and height. Please call toll free for custom lengths.

Each "PlanterWell" self watering reservoir can be used by itself or in conjunction with other "Planter Well" self watering reservoirs to create a self irrigating window box or planter.

Each Planter Well will irrigate 9" of soil beyond it's edge, so one 36" reservoir will keep the soil moist in a window box or planter that is 48" long.

Installation guidelines can be found by clicking on the link named "Installation Guides" in either the dark green band at the top of each page or the light blue link in the left margin at the bottom of each page.

Please Note: We sell mounting bolts for our composite window boxes separately and can be found on the right side of each product page or on our "Window Box Brackets & Bolts" web page. The reason we don't automatically supply bolts and hardware is due to the many different types of walls and siding used throughout the U.S. Your bolt requirements will vary based on the type of wall or siding your home or office has. All of our "Standard" size composite window boxes come with an innovative cleat mounting system that allows you to mount the single composite cleat to your home and then neatly hang the window box. All of our Iron and Aluminum window box cages and hayrack troughs come with pre-drilled 1/4" holes on the back of the cage. Mounting brackets that offer both structural support and add decorative detail are available but also sold separately.

For composite window boxes we recommend you mount them directly to your wall (vs. a bracket) using 3/8" diameter X 3 1/2" long bolts for wood and stucco siding but only when fully secured to the framing studs inside of the wall. Lag shields should be added with the lag bolts when mounting in brick, masonry or block.

For Iron Cages, Aluminum Cages and Hayrack Trough Window Baskets, we recommend (and sell separately) 1/4" diameter x 3" long lag bolts (and of course lag shields for brick, masonry or block).

We urge you to consult your local hardware store, handyman or licensed contractor for more specific direction if required.
