Stretching Pollen With Flour

Mixing a small amount of pollen into plain flour, roughly one part to five, is an old trick for making a tiny collection go across several plants without dumping it all on one branch. The flour acts as a carrier and makes it easier to see where you have dusted. Ratios and application tips using a soft brush are described on https://breederregularseeds.com, along with a warning that damp flour clumps and ruins the batch. It works well for small home projects where every grain of pollen counts.
