Alabama Jumper Earthworms: Will They Aerate Red Clay?

The "Alabama jumper" (Amynthas gracilus) is a non-native earthworm heavily marketed for deep burrowing in clay. However, earthworms need oxygen, and heavy, wet clay is a poor environment for them. They are unlikely to establish or thrive in unamended red clay.

Instead of buying worms, focus on improving the soil with organic matter. Compost, leaf mold, and cover crops naturally attract and sustain native earthworm populations. Amended soil that is loose and well-drained will teem with worms without any introduction.
