Get a great view of big blooms and colorful posies with box planters hung beneath your windows.

Instructions

  • Step 1: Pick wood Pick a 1-by-8-inch piece of lumber that will stand up to the elements.
  • TIP: Cedar and pressure-treated wood are the best choices because they resist moisture.
  • Step 2: Cut front, back, and bottom pieces Cut three pieces of the lumber for the front, back, and bottom pieces of your planter. Cut these two inches longer than the width of your window.
  • Step 3: Cut sides Cut two side pieces of 7¼ inches each. This will create square sides for your box.
  • Step 4: Drill sidepiece starter holes Drill two starter holes in each side of your planter sidepieces with the 1/8-inch drill bit. The hole spacing should be uniform.
  • Step 5: Drill sidepieces onto front and back segments Place the side cap on one end of the planter and, using the starter holes, drill the piece onto the front and back sections with 1½-inch screws.
  • TIP: Glue the side pieces on the front and the back sections before attaching with screws for extra reinforcement.
  • Step 6: Attach bottom Place the bottom section on the rectangular frame and drill four 1/8-inch starter holes along each of the long sides and two on the shorter edges.
  • Step 7: Drill bottom on Drill the bottom section on using 1½-inch screws.
  • TIP: Glue along the bottom edges to reinforce the planter.
  • Step 8: Drill drainage holes Drill two to four 1½-inch drainage holes along the centerline in the bottom section.
  • Step 9: Finish box Sand, prime, and paint your window planter, and mount it beneath your window with the brackets. Grab your dirt and trowel and dig in to beautiful landscaping.
  • FACT: Did you know? Keeping your flower boxes clear of the fungal growth encouraged by dead and decaying flowers helps annuals wto flower rather than going to seed.
