Do not over feed the worms. Overfeeding can lead to odor problems. As your worm population increases, you can add more food per day. Burying the food in the damp newspaper will keep mold from growing in the worm farm.
If your bedding is too wet, add some dry bedding, leave the cover off for a few days, or carefully drain the water off. If it is too dry, add some cool water and leave the farm loosely covered.
Soon you will notice an increase in the worm castings in your worm farm. This makes a great natural fertilizer. And all it cost you was a little time and some stuff that you were going to toss in the garbage.
When you see that bedding is no longer identifiable, you will want to harvest. Worms cannot survive in their own waste. Now if you are raising worms, you harvest the worms. We harvest the castings. The choice is yours.
Some folks sort the worms out
of the castings and put the worms in fresh bedding. We have
other things to do with our time and prefer a split harvest
method. It helps if you have trained your worms ahead of time
for this harvest method. To train your worms, you start
feeding them at only one end of the bin. Do this for about a
week. (Worms learn pretty fast.) Now take the bedding/castings
out of the end of the farm where you were not feeding them and
add it to your plants or garden. You will be removing about
half to two thirds of the bedding/castings in this step. You
will lose some worms, but those were the ones that were not
very smart. Remember you trained the others. Place the
remaining bedding/castings in a container while you scrub the
bin and fix new bedding. Prepare this bedding the same way you
did the first time, damp newspaper, crushed egg shells, and a
handful of dirt. Now add the worms you trained, castings and
all onto the fresh bedding. Feed and you are back in business.
I have found that the worms will move out of the old bedding
in a couple of days. If you want a cleaner farm, you can
remove the old bedding in a few days.
