I was told by someone in a small Hawaii nursery that they used crab/shrimp shell meal to control nematodes? Anyone have any experience with this?

The symptom of "root knot damage" can be caused by either nematodes or insect larvae (e.g., beetle larvae) in the media. It is commonly seen among organic gardeners who have too high a compost component in their soil -- sometimes pure compost. Increasing the inorganic mineral content will help. Adding calcium is a step in the right direction.
