buying a window planter box

window planter boxes with colorful flowers really dress up the exterior of a home. we spoke with master gardener tami gallagher at home sown gardens, who shared her knowledge about window planter boxes — what to look for, plus tips and advice on installing and maintaining them.

  • aesthetics: gallagher says a planter box should be at least as wide as the window and never be so tall that it obscures the view, unless you’re trying to create a privacy screen with plants.
  • style: window boxes should complement a home’s architectural design/era and match the color of the window frames or other house accents.
  • watering considerations: check out self-watering planter boxes to make plant care easier. if you install traditional boxes, gallagher suggests adding a drip-line irrigation system; if not, be sure the hose in your yard will reach. the boxes should come with drainage holes, too.
  • materials: gallagher likes lightweight pvc composite because it lasts longer and needs less maintenance than natural materials. for heavier wood or ceramic window planter boxes, bolt the brackets into the studs or bricks to support its weight, factoring in plants and water-soaked soil.
  • placement: don’t place window planter boxes in windy areas or where water comes pouring down off the roof. note: low and wide boxes are more stable than high and narrow.
  • grow space: most window boxes can’t accommodate deep root systems, leaving no room for plants to mature. the best options are shallow-root plants like geraniums, petunias, strawberries, herbs and cascading ivy.
  • maintenance: to make wood or ceramic window boxes more water- or mildew-resistant, insert a plastic liner. whatever material you choose, monitor for cracks, holes and other signs of deterioration. you don’t want the box to crumble when it’s filled with blooming plants.
