Calcified Seaweed Fertiliser | 25kg Bag

Calcified Seaweed Fertiliser is a natural and organic conditioner for soils and lawns. Made from seaweed calcium and sea shells, it helps break down heavy soils. It also encourages the development of beneficial micro-organisms. Its effect is to neutralise acid and improve the soil structure. In turn this helps plants to develop stronger root systems. As a result, you’re left with healthier plants with more vigorous growth. As the product is rich in minerals, it can also be used as a lawn dressing early in spring.

Once applied to soil, the seaweed quickly breaks down and gradually releases calcium, magnesium carbonate and other trace elements.

Calcified Seaweed will last in the soil for a longer period than ground lime. Therefore, it has a prolonged effect on the soil’s PH.
