This video and photos provide visual information about starting, planting, growing, harvesting and processing 1700 persicaria tinctoria plants. (Japanese Indigo) in 2021.
I have included pictures and information about all the steps for doing fresh leaf fermentation pigment extraction. I use warm water and the fermentation takes 2-4 days.
I hope this visual presentation helps as you extract pigment from your leaves. There are many recommended processes for doing fresh leaf fermentation. This is the one that works for me … most of the time.
