Attach 2 wooden broomsticks to make one long broomstick
You can get long and/or extending poles usually sold for painting, but the standard screw on the end works for mops and brooms and accessories sold for such poles.  Some broom handles have the same screw socket in the end so they can be combined easily.

I have one made of fiberglass that extends to 20 feet. I used it for painting, and then for picking fruit, drying pasta, and any number of things.
