"M&L Landscaping Construction is absolutely incredible! You will not regret hiring Leo and his team for your project. I first hired Leo for one job, and after seeing the quality, precision, and care in his work, I immediately brought him back for a second. The first project included pavers, a retaining wall with built-in seating, a garden bed, patio/paver installation, fence installation, and a composite deck with stairs. The second project was for my rental property and involved an insurance claim to repair the facade of the house. That work included installing stone veneers on the front of my home, constructing a new deck with a roof, building a stone wall with fencing, and completing a blacktop driveway. What truly sets M&L apart is not just the beauty and craftsmanship of their work, but the professionalism, organization, and integrity behind it. Leo’s team is respectful of your property, punctual, and incredibly hardworking. They take pride in what they do and it shows in every detail—from layout precision to cleanup after completion. Equally impressive is how Leo manages the business side of things. He’s communicative, transparent, and extremely reliable—qualities that are rare to find in the contracting world. He provides clear timelines, fair pricing, and proactive updates, so you always know where things stand. Having worked with many contractors over the years, I can confidently say that M&L Landscaping Construction is top-notch from start to finish. I was so impressed that I even referred my parents for their driveway paver installation—and, just as expected, it came out beautiful. If you’re looking for a trustworthy, skilled, and professional landscaping and construction team, hire M&L Landscaping Construction. You’ll be glad you did!"

Lawn Fertilization and Treatment questions, answered by experts

You can use a fungicide to help control powdery mildew, but you should apply it judiciously as it can damage soil health and persist in the soil. Most of the time, proper watering, surface drying, and limiting shade can control powdery mildew without needing harsher interventions. If you have a repeated problem with powdery mildew, you can also try planting a shade-resistant type of grass that will be less susceptible to the fungus.

Choosing fertilizers: slow-release for steady nutrients, organic for eco-friendliness, or specific blends for soil deficiencies or grass types.

First, you should figure out whether you have dormant or dead grass. Dead grass won’t come back, so you’ll have to reseed if you’re hoping for a lush lawn. However, grass can go dormant if it hasn’t received enough water or if temperatures are too cold. If it’s still decently warm outside, you can revive dormant grass by watering it. But if it’s mid-January in New England, for example, you’ll need to wait until the weather warms up again. If you want to keep grass green in winter, consider a grass like Kentucky bluegrass, which maintains its color year-round.

On average, the cost of lawn fertilization is $250, ranging from $80 to $400, depending on the size of the lawn, its current condition, additional treatments, number of applications, fertilizer type, and location. Keep in mind that labor, tools, and equipment make up 80% to 90% of the total cost of lawn fertilization. Additional lawn treatment options include:

  • Lime treatment: $100–$150 per 1,000 square feet

  • Crabgrass treatment: $30–$80

  • Grub treatment: $30–$80

  • Mulching: $150–$400

  • Dethatching: $265–$295

The most effective way to eliminate quack grass without killing the grass nearby is to overseed the area, keep the seed wet until it grows, mow often, and regularly fertilize the area to promote healthy grass that can choke out the invasive weed.
