Know before you buy
Fertilome Over-The-Top II is a selective herbicide designed to target grassy weeds while leaving most broadleaf plants, such as flowers and shrubs, unharmed. However, you should always aim to spray only the unwanted grass to ensure the health of your desired plantings.
You can expect to see visible results within two days of application. The systemic formula works by being absorbed through the foliage, which effectively slows down the growth of the grass.
No, this product is not intended for use on lawns. Because it is a grass killer, it will damage or kill the desirable grass in your turf along with the weeds you are trying to remove.
This herbicide is specifically formulated to control annual and perennial grassy weeds. It will not be effective against broadleaf weeds, such as dandelions or clover.
This is a post-emergent herbicide, meaning it is designed to be applied to grass that has already sprouted and is actively growing. It will not prevent new seeds from germinating.
