A pollen sifter box, also known as a pollinator, is a gardening tool that one uses to remove pollen from a plant (more specifically from its anther) -- a very useful tool in pollen management. Pollination is a process that occurs when pollen is transferred from the plant's anther to its stigma -- allowing fertilization and reproduction. This process only takes place in flower bearing plants called angiosperms.
Pollination management is a process that involves the adding of pollen to plants in order to improve the chances of sufficient pollination (by birds or bees), as well as to supply adequate pollen for bees on plants. Pollination management plays a vital role in horticulture; in fact, it has become increasingly more important because of the decline of domestic and wild pollinator populations. Equally important are pollen sifter boxes. And building one is easy, which is great -- all that a person needs is a few items usually available at home, they are: a box (preferably shallow), framed silkscreen, waxed paper, and tape.
Grab the wooden box and place it on a flat work area with adequate space. Line the inside of the wooden box with waxed paper -- ensuring that the sides and bottom are completely covered, and the waxed paper taped in place. Take the screen and position it flat on the brim of the box. Note that the type of screen that should be used is silkscreen. This sifter box needs a very fine screen, so a window screen won't do. That's it, all done. To use it, simply rub plant(s) back and forth on the silk screen until enough pollen has sifted through the silkscreen. Collect pollen and store until needed.
