How long does it take for fertilizer to kill weeds?

Weed killers, or herbicides, work by interfering with the plant’s ability to produce certain essential nutrients. As a result, the weed slowly starves to death. The speed of this process depends on several factors, including the type of herbicide used, the size of the weed, the temperature and the amount of rainfall.

Weed control in turfgrass systems is important for several reasons. Weeds can be unsightly, reduce turf quality, and can be difficult to control once they become established. An effective weed management program should include both chemical and cultural control measures.

Pre-emergent herbicides are typically applied before weeds emerge from the soil. This type of herbicide prevents weed seeds from germinating and growing into mature plants. Post-emergent herbicides are applied to already-established weeds and work to kill the plants.

So, which should you do first? Should you fertilize or kill weeds? The answer to this question depends on several factors, including the type of weeds you have, the time of year, and your overall turfgrass management goals.

If you have a few weeds here and there, you may be able to get by with spot-treating them with a post-emergent herbicide.

These products will help to kill existing weeds and prevent new ones from germinating.
