I dug up about 1/2 cu. ft. of yucca root, washed & cut up with sawzall into chunks. this stuff is TOUGH!
it definitely makes a soap, but i don't know how much to use for plants... washing the dog is easy, "just add more!" but it's in my freezer since last year, along with 1/2 gal, home-made LAB, that I also have no planned use for. made the bokashi starter strips & just tossed it to my worms(2 cu. yd. worm pile).
thoughts on how to get more space in my freezer? toss em both in the worm pile?!
