6 Benefits of Using Seaweed For Organic Farming

What’s the thing you like doing on a beach? People watching? Picnics? Picking up shells and sea glass? But if you are doing organic farming at home, you can add another activity while you’re lounging on the beach: collecting seaweed. This is one of the best tools, fertilizer, and amendment for healthy soil in the garden or farm.

Collecting seaweed is very basic and very simple. The only supply you need is a garbage bag or basically a big container where you can put the seaweed. The best container is one with small holes or even a burlap bag because it allows water to drain out. The best seaweeds, according to some experts, are those found in the middle of the beach. They should not be too close to the water and may be far up the beach so that water has already started to drain.


Seaweeds contain at least 60 micronutrients including iron, copper, zinc, boron, and manganese. It contains a high concentration of natural growth hormones which allows it to grow rapidly in a natural environment. When applied to plants, it can act as natural fertilizers and stimulate root growth, reduce transplant shock, promote more rapid fruit set, increase frost resistance, and improve storage life. And unlike other soil amendments such as manure, seaweed does not need to decompose before benefiting your garden.


Seaweed keeps the soil moist so it reduces the need for water. It also reduces how often you need to remove the weed. Seaweed contains no seeds that can turn into weeds as bark mulch sometimes does.

Pest control

Slugs hate seaweeds because it has sharp edges and contains a lot of salt. Birds and other pests in the garden dislike it for the same reason. That is why when you use seaweed in your garden, your need for pest control will be eliminated.

Improved aeration

Just like peat moss does, seaweed helps aerate the soil. It has the added benefit of delivering nutrients and minerals. This helps the soil “breathe” so that more varieties of plants and crops can be planted there.

Prevents fungus and diseases

Seaweed helps in the growth of strong and healthy plants, which has enough nutrients to resist fungus and diseases.

Doesn’t blow away

Compost and mulches get blown away by the strong and stiff wind. Seaweed is heavy enough to stay put even when a strong wind blows its way. This is unlike the properties of compost and mulches which can easily give in to wind.
