I have a unbelievable patch of ground that has small red wrigglers in it. I have been adding eggshells, compost, and good soil, to it but wanted to know what I can do to get more of them. Have any of you ordered worms on line before? What is better night crawlers or red wrigglers? Any nutrients that I can add? ( I fish and would love to NEVER pay for live bait ever again)
