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

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. 

One of the best ways to soften your grass and prepare it for planting grass seed is aeration. Aerating your lawn will loosen up compacted soil and facilitate a more even balance of nutrients from root to topsoil. We recommend using core aeration methods for the most effective soil-loosening results.

The best fertilizer for early spring is an organic slow-release fertilizer that sets up your lawn for continued good health and vigorous growth throughout the whole growing season. If your lawn is particularly neglected or has specific issues, you may need an application of quick-release fertilizer alongside a slow-release one for an immediate boost. 

Dog poop can make a fantastic natural fertilizer, but don’t just whack fresh fido feces onto your lawn. Apart from the smell, health risks, and overall ick factor, poop isn’t good for your grass in its unprocessed form. Its high nitrogen levels mean it can burn or even kill your grass. Correctly composted dog poop, on the other hand, is a much safer, odor-free, and effective way to encourage green lawns and blooming borders.

Water the lawn thoroughly, apply fertilizer, and overseed if necessary to promote healthy growth.
