Manufactured in Belgium by Viano, RHS endorsed MO Bacter Organic Fertiliser for lawns is a slow release organo-mineral fertiliser from Viano of Belgium which releases its nutrients evenly over a twelve week period. It feeds the lawn whilst transforming thatch and dead moss into feed, a convenient "no rake" option.

Furthermore, users will not have to scarify their grass after applying Viano Mo Bacter and if the product is spread beyond the lawn, it will not burn plants. Also, unlike normal fertiliser, Mo Bacter Organic Fertiliser will not stain stonework, patios or paths.
For best results, it is recommended to apply Mo Bacter Organic Lawn Fertiliser in the spring, or early summer. To enhance winter turf health, apply the product in late summer or early autumn.

Ingredients: Nitrogen, phosphorus and potassium, in a 5-5-20 (+3% MgO) analysis, plus bacteria (bacillus spp.). A native bacterial species found naturally in soils; but when added to fertiliser, consumes plant material like thatch and dead moss.
