billing is by the job. 10% off first cutting.

"Bryan the owner does not do what he says he'll do. He lied about when he was going to finish my retaining wall project. It has now been 8 weeks and it is still not done!!!! It has been 3 days since they have been to my house!!! He refuses to return my phone calls or emails. I am in the process of getting another contractor to finish the job. One contractor found a bow in the wall that might have to be replaced. This man is a home owner worst nightmare!!!!"

Lawn Fertilization and Treatment questions, answered by experts

A few common lawn maintenance mistakes include failure to use fertilizer, not committing to a yearly maintenance plan, and under- and over-watering your lawn. Other issues that might arise include poor timing of lawn treatments. It’s important to dethatch, aerate, and reseed your yard at the right time of year—preferably in early spring.

In the fall, you should aerate the soil, overseed the bare spots, kill weeds, mow the lawn low, and rake your leaves. By boosting your lawn’s health in the fall, your grass will be stronger throughout the winter and come back healthier in the spring. You should also trim your perennials so that they withstand the winter and are ready for new growth in the spring. 

Routine lawn care costs between $50 and $250 per service, with an average of around $100. Most homeowners need one service per week through the spring and summer, and many switch to snow removal services in the winter. The price you’ll pay will depend on a few different factors:

  • Size of your lawn

  • Complexity of your lawn layout and obstructions

  • Requested services 

  • Home’s location

  • How quickly your grass grows

Depending on the species, most fescue grasses thrive in USDA hardiness zones 3 through 8, though some varieties can thrive as far as zone 10. While it’s a cool-season grass, it has the unique ability to adapt and thrive in many different types of climates. For this reason, you'll mostly find fescue grasses throughout the transitional temperature zones of the country.

Whether organic or synthetic fertilizers are better for your lawn depends on your goals, budget, and plans for other lawn treatments. Organic fertilizer costs more but is likely to benefit your lawn more in the long run by improving the soil as well as feeding your grass. Synthetic fertilizers get faster results but don’t enrich the soil and may contaminate nearby bodies of water if you live on a shoreline. A hybrid fertilizer may be an option to give you the benefits found in both organic and synthetic fertilizers.
