Description

Viano Mo Bacter Moss Killer & Organic Lawn Fertiliser 20 kg

Viano MO Bacter 20 kg is an organo-­mineral fertiliser for lawns that delivers powerful results with an indirect action against moss. Unlike harsh chemical moss killers, MO Bacter naturally destroys moss without leaving black debris, meaning you don’t need to rake out dead moss afterwards. Instead, it encourages the moss to decompose into valuable nutrients that feed your lawn.

It works naturally in soils through beneficial bacteria (Bacillus spp.), which not only destroy moss but also decompose it into valuable nutrients, leaving no unsightly black debris. This unique formulation uses beneficial Bacillus spp. bacteria that break down moss and thatch, enriching your soil and feeding your lawn naturally for up to a 14-week period.
