Lilly Miller Image Herbicide Casoron Granules Grass & Weed Killer

For the best results, apply these granules in early spring before weed seeds germinate, or in late fall to early winter. Timing is critical because this is a pre-emergent herbicide, meaning it stops weeds before they start rather than killing existing ones.

No, this product is specifically formulated for established ornamental trees, shrubs, roses, and fruit or nut trees. It is not labeled for use in vegetable gardens or around edible crops where the herbicide could be absorbed by the plants.

No, Casoron is a pre-emergent herbicide, which means it creates a barrier in the soil to prevent new weed seeds from sprouting. If you already have established weeds, you will need to remove them manually before applying the granules.

Simply sprinkle the granules evenly around the base of your established plants, ensuring you cover the soil surface thoroughly. Once applied, water the area lightly to activate the barrier and lock the herbicide into the soil.

When used according to the label instructions on established ornamental plants, this product is safe. However, avoid using it on newly planted or sensitive plants, as it can potentially damage them if they have not yet established a strong root system.

One application provides season-long control for over 50 types of annual grassy and broadleaf weeds. By creating a protective barrier in the soil, it effectively suppresses germination for the duration of the growing season.
