Seamungus – crumble form

Your plants will just love Seamungus…jam packed full of goodness, Seamungus is a soil and plant conditioner, manufactured by combining the very best of composted raw materials – seaweed, fish, humic acid and manure.

Seamungus is available in the original pellet form, a crumble form and a 1L liquid concentrate. The Seamungus formula remains the same for all three.

Seamungus undergoes a unique composting process, specifically developed to stabilise the nutrients, maximise nutrient availability and to ensure the product is free of any parasites, pathogens and weed seeds. Most importantly, the resultant product retains the microbiology necessary for a ‘living’ product. Whilst Seamungus contains a wide range and good levels of plant nutrients, it is perhaps the additional unique properties contained within seaweed that provide the catalyst for providing higher yields of sustained quality.


Seamungus will help your plants resist heat, drought and frost, along with pests and disease. Seaweed contains a number of naturally occurring growth stimulants – fantastic for promoting plant and root growth and development. Seaweed is also recognised for its ability to retain moisture and increase the moisture level of the plant’s cell sap – this increases the plant’s ability to resist
frost and heat stress. Seamungus will help increase resistance to pests and disease, stimulate healthy growth (both above and below ground) and most importantly, generally improve the wellbeing of your soils and plants.


Seamungus is used for revitalising all plants throughout the year (including natives & lawns) and is ideal for establishing new plants, particularly bare-rooted roses. The ‘crumble form’ is great for use in dry conditions and where more immediate breakdown is required. It contains the full range of plant nutrients in a natural form.
