Envii SeaFeed Xtra

Available in 1L, 5L, 10L and 20L.




Envii SeaFeed Xtra is an organic liquid seaweed fertiliser that offers all the natural goodness of seaweed with some added benefits. Our Ascophyllum Nodosum seaweed is harvested in the UK between April and October when it is at its healthiest. We then add additional iron and plant-based amino acids to provide your plants with further nutrients.

Seaweed is beneficial for your plants

Gardeners have been using seaweed in their gardens for centuries and there is no reason to stop now. Celebrity gardeners Monty Don and Terry Walton champion the use of seaweed fertilisers in their gardens. The benefits of seaweed go far beyond its accessibility and price. It contains natural, essential plant nutrients such as nitrogen and potassium.

In addition to these nutrients, seaweed also transfers anti-stress compounds to plants having produced them during growth at sea. Using a liquid seaweed fertiliser allows easy and convenient access to the benefits of this natural plant aid, without having to scour the beaches collecting your own seaweed.

Foliar application is the best application method, as the plant has no choice but to take the nutrients on board.
