I live in the Hill Country of South Texas. While rebuilding my raised beds (my blacksoil is over 18 inches deep after many years of work) I noticed a large number of really long earthworms. Some are over 6 inches in length but only about 1/8th inch in diameter. They are really vigorous worms. I have never put any worms in the beds. Are these just mega redworms or maybe redworms on steroids or what. I picked several hundred of the worms and have put them into a worm box. I also noticed that they were 10-12 iches down in the beds, but that was the most moist area. Many were in the heavier soil portions of the beds. Any idea what they are??
