All around Oslo, we can find Seaweed and here is why you should collect some for your garden!


Seaweed benefit my garden all year long. I’ve come to rely on seaweed as a valuable, yet free, source of fertilizer, mulch and organic pest control all in one natural material.


  • Saves water and will keep your soil moist at ground level

The purpose of any mulch is to keep your garden soil from drying out at the surface. And by preventing moisture from evaporating, mulch reduces the need for watering. The practice of mulching is essential in areas where conditions are hot and dry.

  • Eliminates the need to weed! No more weed around your veggies!

Mulch covers the soil and blocks new weeds from sprouting. Because the soil beneath the mulch remains moist, any weeds which do manage to sprout through the mulch are easy to pick.

  • Repels slugs and other pests! Yes it does and it work very well!

Slugs are immediately repelled by two things – salt and sharp-edged materials. Seaweed has a natural salt content which repels slugs, and within a few days of application it dries and becomes quite crispy. Slugs do not like “crispy” surfaces, as the sharp salty edges cut into the soft body tissue. While some mulches may provide hiding spots for slugs, earwigs and other pests, seaweed mulch does not have this disadvantage.

  • Enriches the soil in your parcel!

Seaweed is a broad spectrum fertilizer that is rich in beneficial trace minerals and hormones that stimulate plant growth. Seaweed is high in carbohydrates which are essential building blocks in growing plants, and low in cellulose so it breaks down readily. Seaweed shares no diseases with land plants.

  • Boosts lethargic plants

Seaweed fertilizer contains an abundance of fully chelated micro-nutrients which can be readily absorbed by plants without any further chemical decomposition needed.

  • It’s free!
