Meal Worm castings versus Earthworm castings?
I was wondering if anyone knows which is a better fertilizer or soil amendment? Also price wise, it appears that meal worm castings are much cheaper to buy than earthworm castings, in fact I read some places give them away for free. Is the extra cost of earthworm castings worth it? Also, how many pounds of castings does the average home worm farm produce a year? Five pounds or 500 pounds or what?
BTW, mealworms are immature darkling beetles, and I don't know if either the beetles or mealworms would be harmful to garden plants, that is, eat them or their roots.
