Seaweed has been used as an organic fertilizer for centuries.
Contains only Ascophyllum Nosodum from the North Atlantic.
All minerals on earth eventually make it to the sea. Trace amounts of every element are found in seawater. This is the growth environment which envelopes North Atlantic Sea Kelp.
The Kelp is harvested, washed, and dried then turned into a powder for ease of transport and use.
Best Quality Available.

Used as a soil amendment, seaweed helps grow healthier plants which are stronger and more resistant to diseases, root more quickly, which grow more vigorously, and can recover from frost damage more quickly.
Seaweed can be used in combination with organic fertilizers or with synthetic chemical fertilizers to add a full spectrum of trace minerals and natural growth and rooting hormones for more vigorous growth, healthier plants, and better tasting fruits and vegetables.

You can make Seaweed Tea for soil watering, hydroponics, or to use as a Foliar Feed. Take One Gallon of Water, Add in One Quarter Pound of Seaweed Powder. Stir well and let the tea "steep" for 24 hours to three days. Shake it gently or stir every so often. Either strain the mix, or make a "teabag" out of burlap, pantyhose, or whatever convenient material you have that works for you. Use the Tea directly, you do not need to dilute. Do NOT cap the Tea--cover with a cloth--allow the Tea to breathe.

It works best to make separate solutions of guano, bloodmeal, worm castings, etc. in other bottles, then mix your supplemental solutions together with the Tea just before watering the plants or simply water your plants with either the supplemental solutions or the Kelp Tea at separate times.


Seaweed Tea strengthens and enhances plant health if it is sprayed on the plants leaves as a foliar feed. Do not spray more often than every three weeks. After the first foliar feeding and the spectacular results, it is tempting to overdo foliar feeding. If you foliar feed too often, though, the plant cannot handle it. Depending on speed of growth, foliar feeding should be done only once a season or in three to seven week intervals. A three week interval is only when the plant is enjoying vigorous growth with full light; less vigorous growth requires a less frequent foliar feeding schedule.

You can re-use the kelp powder to make more tea if you add two tablespoons more fresh kelp powder.

As a soil amendment, use one pound of kelp for every 100 square feet of garden every four to six weeks of the growing season. It is difficult to overuse kelp in soil, because the roots absorb more selectively than the leaves.

Kelp has been used as an organic fertilizer by tribal people on both sides of the Atlantic for centuries. Members of Celtic tribes of Northern Europe have traditionally used kelp as a soil amendment or fertilizer. While it is reported that in 1622, Squanto, a Pawtucket Indian showed the settlers at the Plymouth Plantation how to catch the alewife (a fish from the Herring family) to use as a fertilizer, documentation of North American tribes fertilizing with kelp is lacking. This may simply be a result of the fact that common knowledge from both sides of the Atlantic was not remarkable and therefore not mentioned in the writings of the time. Looking through the archeological evidence for use of kelp as a fertilizer has never been funded as a priority.
Pacific Coast tribes on both sides of the Pacific used different species of kelp as a direct food source. The North Atlantic Ascophyllum Nosodum has been shown in laboratory tests to have superior characteristics of encouraging disease resistance, natural growth and rooting hormones, and overall healthier plants.
