Hi Tracy, as I live near the sea, I've harvested some seaweed a few times. I've used it the ways that Richard said, plus I put some in a lidded bucket, filled it with water and left in several months to make a liquid fertilizer. I'm sure it must be fantastic, as it absolutely [i]stinks[i]!

Also, yesterday I tried chopping it very fine and putting it, unrinsed, around the edges of my bed as a possible slug repellent - I figured the salt will put them off? Haven't been down the look at my plot yet, so I can't report back yet. Desperate circumstances call for desperate measures!

Good luck with the seaweed anyway, it's good stuff - and free!
