This or Duckweed. Available on eBay. Probably pet shops also. If you click on this it shows on YT. Extended information: Every gardener knows the cycle: buy fertilizer, watch it wash away, repeat. But what if a plant we casually call a “weed” could replace fertilizer entirely? In this video, we explore Azolla, a tiny floating fern that doubles its biomass every three days and pulls nitrogen straight out of the air. Long before chemical fertilizers existed, farmers across China, Vietnam, and Southeast Asia used this living plant to grow rice for over a thousand years, without a single bag of fertilizer. So how did one of the most efficient organic nitrogen sources on Earth get labeled a nuisance? If this kind of deep, practical knowledge changes the way you see gardening, food, or the systems we depend on, consider subscribing. New videos dive into forgotten biology, overlooked solutions, and ideas that quietly reshape how we grow, build, and live.
I will this on to the gardener in the family, the wife. I never heard of Azolla and wonder if we even have it here. Thanks!
That's some good info ,, sure sounds good for farmers and gardeners. But it sounds like it could also be detrimental,, if I understood correctly. Kudzo can take over if not controlled ,, Azolla sounds pretty invasive. And could be spread easily by a bird spraying turds on a creek bank . Am I understanding this correctly??
