On this page you can find out how to use seaweed in your home, in your garden, your orchard, etc.

In Your Garden or Orchard

Next time you are at the beach and you find some fresh seaweed washed up, collect it up (rust your boot out!) and take it home.  Wash it down to remove excess sand and salt then dig deep trenches in your vegetable garden and bury.  The seaweed will rot down over time and feed your garden with all the minerals and trace elements from the oceans.

Alternatively, you can pop in a barrel, add water and let the mix rot down.... this can be a smelly process and takes some months.  Then take out some of the liquid mixture, add a good amount of water and water your vegetables, fruit trees, flowers.... in fact any plants you choose, even your lawn.

For the easy way out, buy some ready made liquid seaweed fertilizer such as Ocean Organics "Urban" www.oceanorganics.co.nz or AgriSea www.AgriSea.co.nz soil or foliar concentrate... they make their mixtures with the additional value of Rudolph Steiner recipes.... it doesn't get much better than that.

In your food.

Seaweed contains many minerals and trace elements good for health and well-being.... can be used as a salad, as a sprinkle on, and for cooking.  Below you will find a variety of recipes to try.  If you are looking for the simple kelp sprinkle on then buy some Pacific Harvest ...... www.pacificharvest.co.nz



There are about 1000 species of seaweed living around the coast of New Zealand. Many are edible, and have the added benefit of being very good for you – they are rich sources of iodine, many vitamins and even protein. Most of the recipes below use moderate amounts of seaweed, together with other ingredients, so they are useful for introducing the untrained palate to the delights of seaweed. When harvesting seaweed, take the younger, outer portions of the blade or frond. Rinse the seaweed in fresh water if desired, then dry. (hanging from a clothes line is a good method). Dry seaweed can be stored in airtight plastic bags for extended periods, and used either in seaweed-based recipes or as seasoning in soups and stir-frys, or ground and used as flour in breads and biscuits.


The best kelp to use if Macrocystis pyrifera, common from the Wairarapa south. It grows below low tide and is easily recognisable because of the bladders that grow adjacent to the fronds. Harvestable all year round.


Cut dried kelp into bite-sized pieces. Pour a thin layer of olive oil on the bottom of a frying pan or wok. Toss the kelp in the oil and let cook over a medium-high element for 2 to 3 minutes. Toss the seaweed continuously. Sprinkle with sesame seeds, honey or sugar. When green and crispy take off the heat and drain on a paper (should be hardly any excess oil). Serve as you would potato chips (goes well with cold beer!!).

Two common types of green seaweed are edible: sea lettuce (Ulva) and Enteromorpha. Both are grass green in colour and are found on beaches where there are plenty of nutrients (eg where there is freshwater seepage). But be careful: these seaweeds also thrive around sewage seepages.

Mixed Green Seaweed Salad

1 cup Enteromorpha

1 cup Ulva

Cream Dressing:

4 tablespoon cream

1 tablespoon wine vinegar or fresh lemon juice

pinch cayenne pepper

sea salt

Wash seaweed quickly in luke warm water. Pat fronds dry. Chop into convenient-sized pieces. Mix cream dressing and pour over salad.

Powdered Green Seaweed Vegetable Seasoning (Aonoriko)

Wash fronds of Ulva or Enteromorpha quickly in cold water. Drain. Spread or hang fronds in sun and breeze to dry until crisp. Toast dried fronds by holding over a naked flame for 2-3 seconds. Take care not to scorch them. Pulverise or crumble and put in a shaker to use as seasoning for salads, coups, seafoods, vegetables, rice, cereals, etc.
