If you keep your eyes (and brain) open, there are many things that can be used for mulch. I have gathered a type of seaweed from the shore of the bay a few blocks from my home. I had noticed that this large, flat lettucelike leaf will dry up crispy on top when stranded by the tide, but when lifted up was dripping wet underneath. The top, crispy layer holds the moisture in until it is refloated by the tide. Makes a great mulch, keeping the ground moisture in around the plants and eventually breaking down into excellent fertilizer. The bay water it is in is not salty, so that is not a problem. The garden does smell a bit like the ocean, but it is not an unpleasant scent at all.

I don’t have access to wool sadly as I think it would go well as a warming mulch for the ground in winter and alternatively cooling in summer. I’m curious though about it breaking down like other mulch. I’d imagine it would take a very long time, or do the worms eventually get it incorporated into the soil?
