I remember my Dad raising Earths,Wigglers(yellow & red),Night Crawlers,Grubs,& The Main Important Wormfood was Coffee Grounds,De-Germed Cornmeal,Ground Eggshells.A Major Rule of Thumb-Never,Ever use even Leaves from ANY Citrus fruit as,In a few months You'll Notice a large Population of some of The Biggest Cockroaches,You have Ever seen in the Western Hemisphere,Roaches are Bane,They Eat The Worms,& Roach poop is Toxic to All but The Earthworms,Not to mention that they Also Escape,& Attempt to Populate,Everywhere,lol!That Could be a Real Big Problem in Houston!I Hope Missesweather Doesn't read this post Before You have built your DogHouse to sleep in!Worm Castings are a Moneymaker in their own rights! Good Luck with this Grand Endeavour!
