Eco Seaweed

18 reviews

Eco Seaweed is a registered organic seaweed extract that is 100% soluble and stimulates a range of beneficial actions including: reduced transplant shock, improved health and vigor, reduced incidence of disease, improved drought tolerance and more. It is extremely concentrated with 100g making up to 200 litres of solution!

Apply every 2-4 weeks to stimulate growth, improve the flavour and quality of your herbs, protects plants from stresses such as cold, drought and insect damage. Apply weekly to sick plants.

We use Eco Seaweed when we are potting our plants up from tubes or planting them in the ground, it reduces transplant shock. We also recommend using eco seaweed on days of extreme heat or extreme cold.

How to Use Eco Seaweed

Eco Seaweed is dissolved in water and applied either as a foliar spray or watered into the soil around your plants. Add 2 spoon fulls to 9 litres of water. (or 1 level tsp)


Note: Eco Seaweed is not a complete fertiliser

It can be combined with Eco Aminogro (this is a complete fertiliser.) Use 45ml of eco aminogro & 1 level tsp of Eco Seaweed to 9 litres of water in a watering can.
