A Clew of Red Wigglers Squirm Their Way into SR1’s Science Lab

That’s right—a clew! For those without a clue, “clew” is the collective noun for a group of earthworms. A clew of Red Wigglers (Eisenia fetida) has officially taken up residence in SR1’s science lab.

While often used as live bait, Red Wigglers are also prized for their role in composting—and that’s exactly why SR1 has invited them in. Composting is the process of breaking down organic material into nutrient-rich soil, a natural fertilizer that supports healthy plant growth. Worm composting, or vermiculture, is one of the most effective ways to enrich soil.

Our Red Wigglers thrive in moist garden soil and enjoy a diet of fresh produce and special worm food. They even seem to have a sweet tooth—their favorites include cucumbers, watermelon, and tomatoes!

As they eat, the worms break down food in their digestive tracts, producing castings (worm compost) packed with nutrients plants love. It’s a simple but powerful cycle: leftovers become worm food, worm food becomes compost, and compost helps grow new food for us.

Though our worms have only been with us for a few weeks, Red Wigglers can live up to five years with proper care. Each worm produces its weight in plant nutrients daily—meaning our compost bin is already busy creating rich soil for future gardening projects.

Worm composting is eco-friendly and can be done on both small and large scales. The relationship is mutual: SR1 provides the worms with a safe home and steady meals, and in return, they provide soil that will fuel our crops and gardens. It’s a win-win partnership!

All of us at SR1 are excited to learn from our wormy friends and look forward to seeing how they’ll support our gardening efforts in the months ahead.ot from our wormy friends, and we hope to learn more as the weeks go on!
