"It's going to cost me thousands of dollars to repair the damage TruGreen has done to my property. There are large sections of my lawn where the grass is now completely gone as the result of improperly applying fertilizer and burning the grass. Before TruGreen my lawn was healthy and pothole free. I am also now dealing with a mosquito infestation. This after 7 treatments from TruGreen during 2022. Again, I never had this issue with my previous lawn care service. Avoid at all costs if you value your lawn."

"Tru green is the worst service out there. I paid up front for the seasonal service and all I got from them is more crabgrass and weeds I have ever seen in my yard. Neighbor is complaining my crabgrass is infiltrating his yard. I have dandelions in October, who gets dandelions in October. They don’t return calls. The worst ever."

Lawn Fertilization and Treatment questions, answered by experts

Before you put down grass seed, you should cultivate your soil or add two inches of topsoil. You should also put down fertilizer at the same time as your seed to prompt healthy growth. Be sure to water after you put down grass seed, especially for the first two weeks.

At its core, soil pH is a measure of how many hydrogen ions are present in your soil. In highly acidic soil (low pH), plant growth is difficult due to reduced microbial availability in the dirt.

In highly alkaline soil, plants may struggle to grow due to iron deficiencies. In either case, a lack of balance deprives grass or plants of some key nutrients they need to grow.

A pH reading of 6 to 7.5 is ideal for most plants. Slight acidity is, generally speaking, less of an issue than slight alkalinity. Many plants can still thrive in slightly acidic soil.

Yes—hiring a professional lawn care company is worth it if you don’t have much free time to devote to lawn care. Lawn care pros will ensure that your lawn receives the vital nutrients it needs to grow and thrive, and you’re guaranteed to have a healthy, beautiful lawn. Aside from that, it’s a convenient service that frees up your time so you can do the things you love and enjoy. 

If you apply too much fertilizer to your grass, it can take about three weeks to recover. If you still have dead patches after three weeks, it might be time to remove the dead grass and overseed the affected area. Since overfertilizing can also cause problems with fungus, leading to further damage to the grass, monitor your grass color and growth for one month after over fertilizing.

Sometimes, pulling nutgrass can cause it to spread. If you do not discard the plant and rhizomes, the nutlets attached to the roots may each sprout. However, if you pull nutgrass repeatedly over the course of several weeks and discard the plant each time, it will weaken the plant significantly, eventually leading to its disappearance.
