Here is an interesting question from Ruthie:
my husband and i are new to worm farming and have read just
about everything i can find regarding food for the worms; we have a
“cultured” nightcrawler which we are going to use for castings and
fish bait; i have seen the mention of grain feeding and would like to
know which grains would be best? what ratios to use etc. there has
been a mention of rye & barley?
would appreciate any information you can supply me with.
I’m not really an expert on this topic, but my hope is that by posting this on the blog we’ll get some comments from readers who do use a lot of grain foods for their worms.
I honestly think a lot of grain products would work well. I’ve heard that a lot of people use chicken ‘laying mash’ as a worm fattener, but have not tried this myself. I’ve used wheat bran mixed with food waste slurry (my homemade manure), but it’s hard to say how effective it was given the fact that it was mixed with a lot of other materials.
I’ve also used brewery wastes (which, according to some experts is an excellent material for worms) but actually found them very difficult to work with – they went anaerobic (and nasty) very easily and the worms didn’t seem to care for them at all.
You mentioned culturing ‘nightcrawlers’ successfully – I would be interested to learn what type of nightcrawlers you are referring to. I have yet to come across someone who has had a lot of success with soil nightcrawlers (such as the Canadian Nightcrawler – Lumbricus terrestris), given their requirements.
