For centuries my family of landscape gardeners have used brown seaweed to feed the earth, this precious commodity was found in the cold water of the Irish Sea off the Welsh coast. Their secret recipe for seaweed tea was used at their nursery and gardens and has been handed down through the generations. My ancestors knew that it made a tremendous difference in the growth, health, and yield of plants.

Our nursery in my home county of Shropshire in England was only sixty miles from the Irish Sea and once a month leaving in a convoy of two of our farm trucks and two cars, members of our family drove across the border, through the rugged Welsh countryside to the shores of the Irish Sea.

In summer my brother, me, and three cousins went along. We played on the shore while the men hired a small fishing boat to go out about five miles into the bay where brown seaweed covered the surface of the sea. When we arrived home in the early evening, our entire family immediately began brewing the nutritious seaweed tea, which in a few days, was scattered in containers alongside those of manure tea readily available for all the plants in the nursery.

Seaweed tea contains naturally occurring root growth hormones that work on the plant root zones to aid in the development and strengthening of roots which in turn produce healthy plants. Recent discoveries show that plant roots do much more than carry food and water, the root zones are surrounded with microscopic bacteria and fungi that specialize in decomposing organic matter, which in turn unlock the nutrients that dissolve in water to fertilize the plants; seaweed tea is the ideal vehicle to make this journey.

Directions – Dilute one cup in one gallon of water.

When to apply – early in growth stage for best results on all your plants every two weeks and the most critical times to apply are:

Just prior to and during germination

During initial root growth

Just prior to and during fruit set and flowering

Just prior to harvest

During drought, high temperatures, excess water and expected frost.



The Narcissus shown here went from dry bulb to what you see in 12 days with my tea.











I had this Rosemary blooming in my guest room in January with my tea. My friend Dory had dug this out in October, stored it in her cool garage, and gave it to me in December.










Seeds soaked in seaweed tea for thirty minutes before planting will germinate much faster than non-treated seeds.

Soak plant roots before planting with one cupful around each stem of annuals, perennials and seedlings.

Foliar spray directly onto foliage in early morning or late afternoon as a pick me up in hot humid weather. Avoid spraying during the heat of the day or if rain is expected soon.

Fruit trees – seaweed tea enable the trees to set a good crop and acts as frost insurance. Spraying apple, pear and peach trees prevents loss of fruit sets when exposed to a cold snap during flowering and helps the trees when stressed to withstand any changes in temperature, drought and disease. The natural growth regulators in the seaweed help the fruit buds to recover and allow them to develop into a good crop.

Note: peaches get two applications – spray when you can just see the pink at the end of the flower buds, then spray again when the petals fall off.

Tree and shrub planting and transplanting – dip the roots of the plant in the seaweed tea and allow excess to drain away. Following planting, apply five cupfuls around small shrubs, trees and roses. This formula has been widely used in my family nursery in the U.K. with great success and is widely used throughout Europe.

Vegetable garden – water in newly planted seeds or transplants with the seaweed tea, four teaspoons per gallon of water.

In mid season – spray plant foliage every two weeks to four weeks.

Pre-harvest – spray a week to ten days before harvest to promote improved storage and shelf life.

Flowering shrubs- spray at first signs of budding and when flowers first appear.

Stress resistance – the effect of the growth regulators in seaweed tea enhances the ability of the plant systems to withstand changes in temperature (heat and frost) drought and disease.

Insect and disease resistance – Liquid seaweed has an adverse effect on insects, particularly aphids, beetles, nematodes and powdery mildew.

Lawns – spray on a moist lawn at first signs of greening and every two weeks to promote a strong stress resistant root system. If the lawn is dormant due to drought, delay spraying until some moisture is present.

Houseplants – soak soil with tea when planting or repotting. Spray or water with tea every two weeks to promote flowering and color intensity.

Do not mix the concentrated tea with any other material

Increased usage or concentration of tea does not increase the effectiveness or yield

Seaweed tea can be applied year round with safety as the tea will not burn or harm plants.





Helpful hints

Apply tea only in morning, late afternoon or early evening

Do not mix concentrated tea with any other material

Increased usage or concentrations of tea does not increase effectiveness or yields

Proper calibration of spray equipment is essential.
