will fertilizer make weeds grow

But here’s the problem: Early spring probably isn’t the best time for you to fertilize your grass or apply herbicides unless you have a history of weed problems.

And unless your weeds are running rampant, try spot spraying them in the fall instead of putting down herbicide over your entire lawn. That’s just one small step you can take for sustainability.

If you’re going to apply fertilizer, Memorial Day and Labor Day are better times to do it. And with recent restrictions on phosphorus fertilizer in many areas and the lack of evidence that potassium will improve your lawn in most circumstances, shop around for fertilizers that are all nitrogen.

Let’s start with the herbicides. Weed and feed products designed for early-spring application usually contain pre-emergent herbicides. They work by preventing weed seeds from sprouting, and they can be an effective way to control crabgrass and some broadleaf weeds.

Kill Weeds Before You Fertilize

Once you have killed the weeds in your lawn, it’s time to keep them out with fertilizer. Although fertilizer won’t wipe out weeds on its own, it can prevent weeds from returning. With the right fertilizer program, you can grow a healthy lawn that remains weed-free on its own. This way, you won’t have to battle the same weeds year after year.

Makes Soil Less Friendly to Weeds

In the simplest sense, fertilizer is plant food. Although your fertilizer may be designed with grass in mind, if you have a lawn full of weeds, they will benefit from fertilizer as well. For this reason, it’s a good idea to use a weed control product before you fertilize. Once you’ve killed the weeds, any fertilizer you spread will be used by your grass only.
