hmm. i use my own compost which has pineapple, papaya, beet, ginger, celery, apple, cucumber, kale, spinach, parsley, tomato, carrot, chile, peppers, coffee grounds, wheat grass, and post bubble hash sludge. i juice 2/3 of my food so there is very rich compost, i need to feed it to worms so i can stop buying local castings. do they have anything with yucca root? im always trying to find new sources of organic yucca. thanks for posting about it, if you do a run of it post your progress and opinions, a lot of us would be very interested in your findings.
