When to Weed and Feed Lawns: Facts To Keep in Mind

What is weed and feed? 

This term is used to describe chemical products that simultaneously kill the weeds in your lawn AND fertilize/nourish your grass. Sounds like a pretty magical product, doesn’t it? 

The downside, however, is that you can’t use these products randomly, as you can unwittingly destroy your lawn if you don’t apply them properly.

When to apply? 

Before applying, get clear on the type of grass and weeds you have because not all products work for all types of plants. 

After you figured that out, check the state of your lawn – are there weeds already growing or do you plan on using a weed and feed that kills the weeds before they emerge? That’s also important for choosing the correct weed and feed product for your lawn. 

Finally, know that weed and feed is best applied during either spring or fall. Don’t even think about winter because once the frost sets in, there’s no way for the product to stick to the weeds and grass. 

If you want our opinion, we think it’s best to apply the product during spring, after the weeds have emerged. Mow your lawn if it’s too tall (also, don’t mow it too short) at least 2 days before the application, and make sure you’re not applying the product on freshly seeded grass – it’ll destroy it. 

After the application, read the product’s instructions to know when to water. As a general rule of thumb, you shouldn’t water the lawn for at least 24 hours to allow the product to do its job. 


As you probably already know, chemical products such as herbicides and fertilizers are toxic for both animals AND humans. Don’t leave small children or pets running around on your lawn while the weeds and grass are being treated. 

On top of that, be very careful what products you’re using. Some low-quality products will damage your lawn irreversibly. Here at Mahoney, we only use the most environmentally friendly, high-quality, nourishing products
