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

While you may see some germination by simply tossing a handful of new seeds on a lawn, you'll have more success by following the proper reseeding or overseeding process step-by-step. Without properly tilling, mowing, amending the soil, and watering your lawn, the new seed could blow away or simply fail to take root.

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.

The best type of fertilizer depends on the type of grass and your desired end result. Generally speaking, slow-release fertilizers are best for grass, as they gradually release nutrients into your soil instead of all at once, which meets the needs of many grass types. However, the tradeoff is that slow-release fertilizers contain phosphorus, which negatively impacts local water quality. Also, some grasses require different formulations to meet the demands of the soil. Test your soil to see how acidic or alkaline it is before choosing a fertilizer. 

In most cases, it is worth paying for professional lawn care. DIY lawn maintenance is possible, but it can get extremely time-consuming, especially to make your property look well-maintained. Not only is lawn maintenance time-intensive, but it can also get expensive, even to DIY, especially considering the cost of fuel and maintenance for your lawn care tools. Professional lawn care services average around $100 per service, making it a relatively inexpensive investment, especially for how much time it saves you.

Starting a mowing business can be profitable if you manage your business wisely, calculate costs accurately, and invest in time-efficient, high-quality equipment. With good customer service, you can lock in loyal customers who invest in weekly lawn care services that turn your business into a successful one. 

Lawn care businesses can earn anywhere from $40,000 to over $100,000 per year depending on how you operate, but you’ll need to factor in the cost of equipment to determine your actual profit margins.
