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

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.

It depends on the type of grass and the condition of your lawn. We advised you to fertilize your lawn at least twice per year. However, warm-season grasses and nutrient-deficient lawns may need to be fertilized up to four times a year. Remember, you don't want to over fertilize either, so soil testing can help to determine if your lawn lacks nutrients and if it’s ready for another application.

Fertilizing is optional after dethatching. However, the period immediately after dethatching is generally considered the best time to fertilize your lawn because the thick debris is now gone. As a result, applying water and fertilizer as the final steps of dethatching can help to spur incredible growth.

Bermuda grass may be drought-resistant, but it still needs to be watered once or twice a week. The suggested amount of water Bermuda grass needs varies from season to season. Bermuda grass needs about 1 inch of water a week in summer, fall, and winter; it needs up to ¾ inch in spring.

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.
