Slug deterrent


I have hostas that have been chewed by slugs in the past years. They are starting to unfurl their leaves now. I was wondering if zebra mussel shells might be an option to add around the base of each hosta to hopefully stop the slugs. There are piles of shells down at the beach, Lake Ontario.
I have bark mulch in the gardens now.


The bark mulch provides a good hiding place for slugs so start to pull it back from your hostas now and let the birds help out with reducing the population of slugs.

There has been some research done on composting zebra mussels that seem to support the use in soil:


In areas without contaminant concerns, zebra mussel shells are a good source of calcium and can be used for soil enhancement.


So it sounds like a good idea. Please let us know how it works for you.

Thank you.
