Balsam fir tips are the end section of a balsam fir branch, often used to make wreaths during the holiday season. Balsam fir tips are typically between 12 to 20 inches long. The tips are broken into sections to make wreaths, but you can keep them long to decorate a window box. Balsam fir tips have dark green needles averaging 1 inch long that are rounded on the ends. The overall shape of a balsam fir tip can be compared to the shape of a Christmas tree. The tips have a long-lasting aromatic fragrance that you can enjoy through the holiday season.
Select balsam fir tips that have similar heights to decorate the window box. Fresh balsam fir tips are harvested in Maine during the late fall. Many retailers will ship the tips to you in bulk.
Cut a section of floral foam to fit inside the window box. Place the floral foam inside the window box; make sure that the foam fits snugly from end to end.
Cut an 8- to 12-inch strip of floral wire for each balsam fir tip that you plan to add to the window box. Longer tips require longer wire strands for best support. A 4-inch section at one end of the wire will fit inside the foam; the remaining length of the strand will be attached to the base of the balsam fir tip for support.
Attach all but 4 inches of the wire strand to the center stem of each balsam fir tip with small strips of floral tape. Stand the wired tips into the floral foam along the width of the window box. Make a single row in the center of the window box, or offset several rows, one behind the other, to decorate the window box.
Wrap twinkle lights around the balsam fir tips.
Hang tiny glass or plastic holiday ornaments from the fir tip's branches.
