Growing Tips
Amaranth seed is very small. Mix seed with fine sand at a 1:10 ratio for more uniform broadcast or drill seeding.
Harvest by cutting panicles when they begin to shatter; thresh by rubbing through a screen and winnow to clean.
Young amaranth leaves can be harvested as a secondary crop (similar to spinach) without significantly reducing grain yield.
