Growing Dulse

Dulse is a fast-growing, salt-tolerant plant that thrives in coastal zones. It grows abundantly in saline water and is highly valued for its high nutritional value, high digestibility, and trace minerals found within the leaves. Dulse is also an excellent source of calcium, iron, vitamin A, and vitamins K, C, and B6. Dulse is an annual herbaceous plant that produces thick leaf blades that grow upright from the stalk of the plant. This annual nature allows it to grow on sandy shores or dune areas where other plants would not be able to grow.

Obtain dulse seeds

Purchase certified dulse seeds from a reputable supplier or collect them from mature dulse plants.

Grow dulse indoor

If you don't have access to the sea, you can cultivate dulse in indoor containers using sea mineral solutions.

Grow dulse outdoor

Choose an area with minimal pollution and direct access to cold seawater. Attach the seeds to ropes and submerge them in the water, allowing natural currents to aid the growth.

Harvest dulse

When the dulse turns a vibrant red color, harvest it by gently removing it from the ropes. Rinse it with freshwater and dry it thoroughly before using or storing.
