Comments about 23" Self-Watering Windowbox:

The only problem is the cap that covers the water reservoir does not fit properly. But everything else is great about this product. I will love it during the summer and when I'm away on vacations, knowing that my plants won't dry out and die on me.

    Comments about 23" Self-Watering Windowbox:

    This is my fourth planter box from Gardner's Supply and I have never found any that compare. We have a deck that gets full Sun and the flowers I plant in the three on the deck are gorgeous all summer. The one I just purchased will go on the front porch railing. I looked everywhere for alternatives and there is nothing out there as good . Keep the well full and your plants will flourish. Worth the price!

      Comments about 23" Self-Watering Windowbox:

      I've used these (in white) for many years. When we re-landscaped our front yard last fall, with some local red sandstone interest rocks, I realized that the Terra Cotta planters would tie it together so much better than white. On the front porch I put shade-loving plants like begonia in them, because the roof overhang protects them from sunlight. With an automatic drip system to keep the reservoirs filled, the flowers do really well. I'll be keeping the 35" white ones on the back deck parapet, which I usually plant with petunias.

        Comments about 23" Self-Watering Windowbox:

        We purchased the self-watering window boxes several years ago and were pleased with the way they maintained our in an all-day sun location. Our deck railings had a profusion of flowers all summer long. That's why we re-ordered replacements for next year when they went on sale.

        The water gauges were not durable, nor accurate and we discarded them after two years. Hope they have been improved.
        I like the style of the boxes and the choices of color.

          I've always wanted a window box and finally had the opportunity to install one. We now own a house and have a window that just begs for color beside the dining table. No need to worry about watering! I think I'll order another once the a/c is out of the window, to liven up autumn and spring.

            The self watering containers work so well. They distribute the water evenely. They are also attractive and durable.

                The original built-in window boxes on my house are both under roof overhangs, so they don't get much, if any, rain. They are also awkward to water, so plants always died. I planted these containers and then set them inside the existing window boxes. With the self-watering containers, I have outsmarted my windowbox woes.
