DO NOT put Coffee grounds on your Plants ! - University Research Reveals

In this video we are going to look at a report published on the US Department of Agriculture website revealing research that spent coffee grounds applied directly to plants reduces plant growth. However composting the spent coffee grounds in a specific way and duration can produce a safe product that is beneficial to your garden.
The Scientific research by University of Melbourne is titled ‘Applying spent coffee grounds directly to urban agriculture soils greatly reduces plant growth’.
