Q.Is It Beneficial To Use Fresh Water Seaweed In Compost.
There is mention of the beneficial aspects of adding salt water seaweed in a recent article on composting but no mention of fresh water plant material. I live on waterfront property off L.Ontario and have a great supply of seaweed that washes up on my shore.I have put some in my composter but thought others may be alerted to the use of fresh water seaweed.
