Established in Londonderry New Hampshire over 20 years ago, Groundhog Landscaping Inc., has grown to become one of the largest full-service landscape companies in southern New Hampshire. We believe our consistent growth and success is because we offer competitive pricing, we know our costs, and we deliver value.

"I hired Groundhog Landscaping for general weed and feed service for my lawn. Their machine leaked gasoline all over my lawn. They came out to “fix” my lawn and made a repair. Meanwhile they are sending me a bill for the service they performed. I told them I would not pay it until the lawn was fixed. 10 weeks after they have not fixed my lawn and it is a complete mess. Please see the pictures"

Lawn Fertilization and Treatment questions, answered by experts

You can fertilize right after mowing as long as you've collected the clippings. If you leave grass clipping, they can form a mat that prevents the fertilizer from reaching the soil. Plus, grass clippings are rich in nitrogen, so if you leave them and then apply fertilizer, you can end up with too much nitrogen in the soil.

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.

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.

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

If you use a starter fertilizer designed for this purpose, you can overseed and fertilize at the same time. If you opt to use a fertilizer for established grass or one with a weed control component, it's best to wait at least four to eight weeks after seed application to allow the new grass to take hold and establish itself.
