Over the winter …
Fresh seaweed can be used as a mulch at the end of the growing season. As an organic material, seaweed will break down over time and will condition the soil ahead of the following growing season. Spread a layer of soaked and rinsed fresh seaweed 1-2 inches deep across the soil surface of garden beds. Some potato growers also have found success with putting down a layer of seaweed in their potato trench followed by a layer of compost before placing the seed potato. This method ensures that as the seaweed breaks down into the soil, the nutrients are readily available near the plant’s roots.
Seaweed can also be composted and is considered a “green” material in your compost pile or compost tumbler. You may want to chop the seaweed to 1-2 inch-long pieces to speed up the composting process to a few weeks. Layer in the seaweed in your compost pile with other natural plant materials. Seaweed is a compost accelerator because it contains a lower amount of cellulose found in other plant matter.
