Anbautipps
Harvest leaves just before flowering when indican content is highest; cut plants 15-20 cm above ground for regrowth.
As a legume, indigo fixes nitrogen and improves soil fertility — excellent in crop rotation with nitrogen-demanding crops.
Dye extraction requires fermentation: soak fresh leaves in water for 12-24 hours, then aerate the liquid to oxidize and precipitate the indigotin pigment.
