Excellent post on how to manage lambs quarter for harvest. This kind of info is just gold! Let me know if you give it a try or have done this before.
Also, Oikos Tree Crops, which is on my seed sources page, sells a species they call ‘Giant Tree Spinach’ that has pink young growing tips and seeds. Perhaps it won’t look so weedy if it’s an exotic color?
Worth a try.
