I use it as mulch for my large plants in pots and it works great.Some people warned me the salt might kill the plants, but it has never happened to me. Also mixed in the compost for tomatoes

While it can be a great soil ammendment, you will want to make sure that what you will have planted in that ammended soil can handle salt. For instance in the bamboo growing community, seaweed is HIGHLY frowned upon, as the salt it adds to the soil will kill or severely hamper the bamboo’s growth, as it is sensitive to salt.

I live near a lake where they have to harvest the seeweed to prevent problems. Seeweed is excellent to add to a compost bin. It is so rich in nutrients. Denise

We live right on the coast of Maine and every year I scoop up loads of seaweed to mulch my garden in winter. In summer, I fill a plastic tote with the stuff, fill with water to cover, let steep and water all my potted plants. They thrive on this stuff. I highly recommend it.

I used it. You’re neighbors will love you. It is best placed in the garden up north in the winter.

Also yours and the neighbors cats will go roll in it and come home stinky. It’s a great way to discourage your neighbors from letting their cats loose.

I don’t know that it made a huge difference in plant growth. I’ve found worm castings and fish emulsion to be better fertilizers if you want natural ones.

( Same warnings apply for fish emulsion . )

Anne did a nice post about seaweed back in October-

Everything I’ve read about using it pretty much says to load it on, you can’t overdo it and it increases the disease resistance in most plants as well as helping to keep some bugs away.
