"Ian and his crew worked diligently to install a new retaining wall and walkway for my front yard. They worked through the torrential downpouring and cold weather to get it all completed before I got back from a business trip (I knew it was raining due to my view from my ring doorbell). Needless to say, everything turned out better than I could have asked for. I definitely would use The Difference Landscapes again, and I Strongly recommend them to anyone who needs some hardscaping done."

Lawn Fertilization and Treatment questions, answered by experts

If you notice your grass is growing quickly and it’s hard to keep up, cut down on how much you water and fertilize it. Another helpful method is to mow the grass at the highest setting your mower will allow. Mowing at a higher setting slows grass growth since the blades won’t need to repair themselves as quickly if they’re kept at a longer length.

The cost ranges from $50 to $200 per visit, depending on the property size and services required. Larger properties or additional tasks like fertilizing may cost more.

If your lawn and general landscape are struggling, consider calling a local landscape specialist to suggest lawn amendments, local plants, and hardscape changes to boost the long-term health of your outdoor space. While you may be able to take on small projects yourself—such as reseeding your lawn or testing the soil—a professional can help you build a plan to bring a struggling yard back to life quickly.

Yes, it’s always a good idea to fertilize your lawn before a major leveling project. This step gives your grass the nutrients necessary for healthy growth, helping it recover and replenish itself faster. However, you should do this at least three weeks in advance, as the leveling process can disturb the newly-applied fertilizer.

Grass will grow back after being sprayed with vinegar. If you’re looking for an alternative to chemical herbicides, vinegar can help you manage weeds. Use a mixture of 1 gallon of white vinegar, 1 cup of salt, and 1 tablespoon of dish soap to spray on your grass. This will kill the grass at the surface while keeping the roots intact, so it’ll eventually grow back. You’ll need to use an herbicide or manually remove the whole root system to get rid of grass for good.
