This is what I like to see. Pictured above are some chunks of clay with some of my Texas Jumpers working through them with no problem. The ability of these native Texan worms to work in clay is what makes them suitable for adding directly to your garden or raised bed. They are a hearty worm that grows to 6 inches or more in a few months time. The strength that they have at a few weeks old and small size is what separates them from European Nightcrawlers or Red Worms (eisenia foteda). This strength makes them great aerators and tunnelers for your soil. They can dive and tunnel several feet and can survive through our extreme temps. Pick a spot that has good shade for these worms, keep it composted, covered (old carpet or something similar), and watered for best results. Once your population is established in several weeks, you’ll be ready to start moving them around a couple of handfuls at a time. With a little patience and persistence, you’ll have worms all over.
I broke open a clay clod and found this young worm working through. If these worms can handle this South Texas clay and caliche soil chances are they can benefit yours.
