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 don't want to over-fertilize your lawn because it can burn the grass and even kill it. Healthy soil usually requires two fertilization applications a year during the height of the growing season. This fertilization schedule typically starts at the start of fall and the end of spring, depending on the grass type and plants.

Overfertilizing can burn and kill the grass as well as upset the soil's nutrient balance, leaving your grass prone to disease and infestation. You'll know that you have overfertilized your burn when you have recently fertilized and begin to see brown and yellow patches of dead grass that need to be reseeded. 

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.

The best fertilizer for thick Bermuda grass is an organic fertilizer with an N-P-K ratio high in nitrogen, low in phosphorus, and low in potassium. Organic fertilizers help Bermuda grass grow stronger and healthier by retaining water well, supporting microbiome life, and promoting long-term soil health. However, this type of fertilizer is more expensive than synthetic fertilizers. 

Post-dethatching, lawn recovery includes watering, fertilizing, and reseeding as necessary to restore health and promote growth.
