SaproGro™ 1 L — registered organic liquid fertiliser
The entry-size bottle for home gardeners. SaproGro™ is a registered organic liquid fertiliser drawn from a single natural source — Latvian freshwater sapropel. Highly concentrated: diluted 1:400, one litre makes up to 400 litres of ready-to-use feed.
What it is
Sapropel is a mineral-rich freshwater lake sediment, laid down over thousands of years, that naturally carries a broad range of macro and micro nutrients and organic matter. SaproGro™ delivers that broad spectrum from a single natural source — not a synthetic blend.
