If you have a problem with weeds in your yard, it’s important to find the best grass fertilizer with weed killer to keep your lawn looking neat and weed-free all summer.

While you can always buy fertilizer and weed killer separately, there are plenty of products that combine them, which makes these landscaping tasks much easier. Of course, everyone’s lawn is different — some have tons of weeds, some have only a few — but because these mixes also include fertilizer, they’re good for nearly every type of lawn.

The best grass fertilizer with weed killer is one that will last a long time (preferably all summer) and will prevent multiple types of weeds, like crabgrass and dandelions.

Most grass fertilizers with weed killer come in large bags or spray bottles. Keep in mind how much product you’ll get for the price, as one bag may be enough for a smaller yard, but you will need multiple bags if you have a lot of land.
