This year, we saw the arrival of a new form of fertilizer. This one came all the way from South Africa! Dr. Riaan Lourens on the wonders of ‘Kelpak’ – a natural seaweed-based fertiliser that can be used to improve plant growth, yield & quality in field veg & potatoes, protected edibles, ornamentals, or indeed any crop!

Seaweed has been used as a soil improver for centuries, particularly in coastal areas. Seaweed contains several useful plant nutrients, including nitrogen, potassium, phosphate and magnesium. There are dried and liquidised forms available from garden centres and seaweed is a common additive to fertilisers, both organic and non-organic.
