What does seaweed do for plants?

Seaweed, also known as macroalgae, is a type of algae that grows in marine environments. Seaweed has been used for centuries as a natural fertiliser due to its high nutrient content. In recent years, seaweed has gained popularity among gardeners and farmers for its ability to improve plant growth and health. In this blog post, we will explore the benefits of seaweed for plants.

Increased Nutrient Uptake

Seaweed is among the most nutrient-rich plants on earth. It contains a range of essential nutrients, including nitrogen, potassium, and phosphorus. These nutrients are essential for plant growth and development. When seaweed is added to the soil, it helps to increase the availability of these nutrients, making it easier for plants to absorb them. Additionally, seaweed contains trace elements that are often lacking in soil, such as iron, calcium, and magnesium. These trace elements are important for plant growth and can help to improve plant health.

Increased Resistance to Stress

Seaweed contains compounds that can help plants to better withstand stress. For example, seaweed contains compounds called betaines, which help plants to retain water and protect them from drought stress. Seaweed also contains compounds that can help plants to better withstand insect and disease pressure.

Improved Soil Health

Seaweed can help to improve soil health by adding organic matter to the soil. Organic matter is essential for creating healthy soil that is rich in nutrients and has good structure. Additionally, seaweed can help to stimulate the growth of beneficial soil microorganisms, which can help to improve soil fertility. By improving soil health, seaweed can help to increase plant growth and yield.

Other Benefits of Seaweed for Plants

In addition to the benefits outlined above, seaweed has other benefits for plants. For example, seaweed can help to improve the taste and quality of fruits and vegetables. It can also help to increase the shelf life of produce by reducing the incidence of rot and decay. Seaweed can also help to reduce the need for chemical fertilisers and pesticides, making it a more sustainable choice for farmers and gardeners.

How to Use Seaweed for Plants

Seaweed can be used in a variety of ways to benefit plants. One of the easiest ways to use seaweed is to add it to the soil as a fertiliser, just like we have with EveryPlant. Seaweed can be applied directly to the soil or added to compost. Another way to use seaweed is to make a liquid fertiliser by soaking seaweed in water. This can be sprayed directly onto the leaves of plants to provide a quick nutrient boost.

Conclusion

Seaweed is a natural and sustainable way to improve plant growth and health. It contains essential nutrients, can help plants to better withstand stress, and can improve soil health. By incorporating seaweed into your soil, you can help to increase plant growth and yield, improve the taste and quality of produce, and reduce the need for chemical fertilisers and pesticides.
