Organic Pre-Emergents

Pre-emergent organic herbicides are used as weed prevention in that they are applied before a weed seed germinates and they stop the weed from ever growing. The most common form of organic weed prevention is corn gluten meal. This granular pre-emergent is applied as a preventative measure against weed seeds that will try and germinate the next season.
