Salt in Seaweed Mulch

Grub · October 3, 2006

There was a word or two on seaweed mulch here somewhere, but nothing that tells me whether I should rinse it or not.

The sacks of weed I collected aren't kelp but the dried ribbon-weed or seagrass you see in estuaries. It looks like perfect mulch but is quite salty.

My test batch that was rinsed and dried still tastes salty.

Is salt gonna be a problem in my beds in the long term? I want to use the seaweed or seagrass mulch under the usual sugarcane mulch I use to offer a few more trace elements during the season.

Thanks, Grub.
