I
have WORMS, and darn proud of it!
As part of
my Master Composting course, we were treated to a discussion about
earthworm composting. Fascinating stuff! I never knew worms are
asexual, bisexual and unisexual, depending on their 'mood'. I've
never looked closely to determine which of my earthworms are pregnant,
and what the eggs look like in my compost. I never contemplated
the huge differences between the different earthworm types, either.
Apparently, my garden variety are ok, but there is a 'super earthworm',
called a brown nosed composting worm. And, no, the 'Red Wigglers'
you buy for fishing aren't suited at all to garden climates. (A
clue is the bait shop keeps them in the refrigerator.)
Worms are
best utilized in the compost bins, and in permanent plantings
that you're not likely to rototill them into emulsion. Worms aerate
the soil, and eat organic matter, turning it into 'castings',
or manure. Worms enjoy nothing more than wormy company. They cluster
in well, clusters, and if you have one happy earthworm, you probably
have a whole colony mining your soil and fertilizing as they go.
People who
raise rabbits should not discount the benefits of a worm bed underneath
the rabbit hutches. It's a symbiotic relationship that is hard
to beat. Besides breaking down the urine and droppings, earthworms
will also ingest the spent pelleted feeds and any dropped fresh
groceries or roughage the rabbits spill.
Occasionally,
you'll want to use all this black gold the worms have created
out of the rabbit bins. The best method is to wait for a bright
sunny day and scoop or shovel the manure, worms and all onto a
drop cloth or tarp. Let them languish in the sun for a little
while, and the worms will scuffle to get away from the top of
the pile. You can then rake or shovel the composted material wherever
you want, leaving a thin layer of earthworms and compost to replenish
your bins. You do have to keep an eye on the exposed worms while
you're waiting on them to evacuate the mound surface. If you leave
them too long they'll figure out how to crawl off the tarp and
out into your lawn, or wherever you have the project laid out.
One of an
earthworm's favorite snackie food is paper. They seem to relish
the cellulose in paper pulp and break down newsprint, paper bags,
and even cardboard very rapidly. At the office, we frequently
shred documents and large, handwritten meeting notes. An interesting
(and scary) aside is that when I bring my worms a feast of shredded
paper, they'll actually turn toes up and die or leave town if
it's over 50% laser print documents. Newsprint today utilizes
soy-based inks, but whatever the ink source for printers and copiers,
it's bad news for garden beneficials.
Ok, so you
want to grow your own earthworm castings but don't have a compost
bin set up yet, and aren't willing to raise rabbits just to benefit
your worms. One of the neatest ideas I've seen in a long time
is the worm bin itself. Get a large rubber container such as the
Rubbermaid storage containers, and drill a QUAZILLION tiny holes
in the sides and bottom(*). Make sure the top fits securely, and
drill another quaz here, too. Fill it about half full with regular
garden soil and then go beg some worms from someone. This can
be an indoor project, if you only drill the holes in the cover
and top 1/3 of your container. Otherwise, look for something to
set your project on to protect your floor.
Later
note: Those plastic storage boxes work just as well without having
the holes drilled. Apparently, enough air leaks in around the
top that it's not necessary to provide extra breathing vents.
Using butter tubs, coffee cans, etc., however, you would want
to put some holes in the containers.
Yellow
Rose Crossroads School set up an experimental system that
seems to work quite well. They took clean 25 gallon molasses cattle
feed tubs and cut the bottoms out of them. They dug holes for
the tubs to bury them in the soil, leaving about 4" lip exposed.
They drilled a few holes in the lids, but since the systems were
buried and had the bottoms removed, no holes were drilled in the
sides of the tubs. Each system was fed a different form of trash
to give a wider test range of how well the worm residents fared
in each. All were allowed shredded paper, which became especially
important during heavy rains when the worms needed to migrate
to the soil surface for oxygen when their homes became saturated.
An interesting
indoor home project can be easily created out of a large butter
tub or something plastic you don't mind poking holes in. Using
a small nail, drill your quazillion holes in the lid and top 1/3
of the container. Put a couple of handfuls of yard dirt and your
prized earthworms inside. Feed them irregular feedings of coffeegrounds,
fruit peelings, a little shredded paper, etc. Make sure you have
enough dirt in the container that you can bury kitchen wastes
thoroughly to avoid decaying smells and 'unmentionables' hatching
in it. Check your worms often, and mist the soil surface with
water if it seems too dry. If the worms are hanging out throughout
the container, it's probably within their comfort zone. If they're
balled up at the bottom in a hibernating huddle, you probably
have them in too cool a location If they try to crawl out, they're
too warm. This size container makes a nice experiment, what will
decompose rapidly, what the earthworms seem most inclined to eat
first, etc.
When they
become overcrowded, either 'repot' to a larger container or take
1/2 the worms and the castings to your compost bin and add fresh
material to those who remain.

Update
John says
I shouldn't tell this to anyone but I think it's neat! For Christmas,
he got me a paper shredder and 2 more Rubbermaid tubs for the
worms! They had gotten very crowded in the original box, ate up
the kitchen waste extremely fast, and were starting to stay constantly
wet which was not good for them.
I divided
up the original bed of worms into one of the new ones, and added
shredded newspaper to both bins. I'd stacked up some egg shells
and stuffed them into a corner of the first bin, and when I pulled
the shells apart to crush them, each layer was a mass of earthworms!
(Earthworm Condos?) (I didn't crush the shells, decided to see
how long it takes the worms to compost them out.) I added the
shredded paper to one end of each box. Waited a few days and looked
in. Both bins still had the earthworms in the original soil, and
some brave souls had gradually crawled over to the paper side.
Only the first inch of contact with the earthworm castings had
any worms in it, however.
Earthworms
can't see, and can't mate unless they blunder into each other.
It takes two of the same length to match up, so after a large
disturbance like dividing the boxes, I expect it will be awhile
before they locate each other and begin to breed again. Cornmeal
in the container is an attractant to them, and though it probably
doesn't entice them to breed quicker, it does allow more earthworms
to mingle and search out their partners.
I already
have several pounds of rich earthworm castings to use, and as
soon as the temperature warms up outside, I'll remove the worms
from one bin and add their fertilizer to some of my greenhouse
plants.(Used as 'manure tea', this stuff really works well to
perk up winter-tired container plants.) Replacing the worms into
fresh 'goodies' will disturb them farther, but by then, the second
bin should be going strong.
