Worm castings I think are better for several reasons. They are a lot less effort for you than rabbits. Plant benefits are immediately available. You don't have to buy them food. No vet bills are ever received. Dogs never are attracted to worms and they won't run away. Al

Both are great additions but pound for pound, worm castings are superior. They are considered the Cadillac of composts - relatively high nutrient content, very high populations of beneficial microorganisms, a good source of humic acid and they contain beneficial plant growth hormones (auxins). They enhance seed germination. They also absorb 3-4 times their weight in moisture, contibuting significantly to soil moisture retention and they are heavily populated with both nitrogen fixing and anti-pathogenic bacteria.

Although Al makes some very valid points, worms tend not to make great pets :-) I wouldn't trade my bunnies for worms but I would consider both. Since I have a source for as many worm castings as I can use, I opt to keep my bunnies both for their appeal and their poop output.

before passing biology on farm and forest in a university in 1954,I was taught by the Benedictine monks in the Monastery which they taught me always look after your earth worms without them you cannot grow anything and Henry v111 made his farmers at Christmas dig a hole and put in the hole one fresh egg a very ripe apple to feed them on in the coming Winter look after them ,they told me try this put a fresh egg in the hole and one banana ,cover it up go Back in two weeks you will find the worm with young ,and if you have a earth worm casting you will fine 5 earth worms will,eat a pound of food scraps every day ,after two weeks remove the earth worms to another casting and feed your vegetable or seeds on this

The best is both!

Re: Worms

There is no reason not to put both rabbits and worms to work for you.

But instead of worm bins, feed the worms that are already in your garden and eliminate the middle man. Mulch heavily with shredded leaves or straw and sprinkle in some used coffee grounds and /or grass clippings. Your in-ground worm population will explode with no additional work from you.
