SeaFeed Xtra is an organic liquid seaweed fertiliser that harnesses the natural power of seaweed to promote better plant growth and improve soil structure. This specially formulated liquid provides a convenient way to enjoy the numerous benefits of seaweed without the need to gather it yourself. Seaweed has long been cherished by gardeners for its ability to enhance soil health and plant vitality, and SeaFeed Xtra brings these advantages straight to your garden.

Harvested from Ascophyllum Nodosum seaweed in Ireland during its peak season between April and October, this formula offers your plants the very best of nature’s nutrition.

"I purchased your liquid seaweed on recommendation from a friend. I have not yet used the product as I am in the process of buying a dispenser to dispense 5ml doses. Unless I have missed something. I believe you are missing a golden opportunity to offer dispensers as part of your sales"

I used this product in

"I used this product in conjunction with Maximato for my tomatoes and Allgrow for my flowering plants for the first time last year and was blown away by the results. 2 tomato plants in a container that holds 56l of compost and the result was as per the attached photo ( unfortunately I didnt take pictures of them when the fruit arrived. A trip to Jamaica put paid to that. As for my hanging baskets a photo when they were first planted late in June and a second at the beginning of August. Needless to say I have stocked up for the coming season. Give it a go you WILL NOT regret it."
