Can red wiggler compost kelp

Yes, red wigglers can compost kelp. These worms are effective at breaking down a variety of organic materials, including seaweed like kelp, which is rich in nutrients. However, it's best to chop the kelp into smaller pieces to speed up the decomposition process and avoid any potential salt concentration issues, as excessive salt can be harmful to the worms. Overall, incorporating kelp into their diet can enhance the nutrient quality of the finished compost.
