Horsey Irrigation Services was born in Connecticut with a simple idea: irrigation service should feel like a favor from a good neighbor, not just another transaction with a contractor.\n\nAfter more than 15 years working with irrigation systems across homes, condominium associations, and commercial properties throughout New England, William Quintanilla decided to found Horsey Irrigation Services together with his partner Oliver Arias to do things their way: with real quality, fair pricing, and direct communication with every client.\n\nWe are not an anonymous company with a distant call center. When you call us, you talk to William or to Oliver. When we arrive at your property, we arrive with the same truck, the same crew, and the same values we've carried since day one.

Lawn Irrigation FAQs, answered by experts

Technically, yes, at least some of the grass seed you throw on the ground will germinate. If the area doesn’t have good drainage, rain or overwatering can move seeds before they have germinated, leaving your patches still patchy. What does grow won’t have strong roots if there isn’t proper aeration.

Too much clover in your lawn can indicate several issues with your soil. Clover can thrive in soils with abnormally high pH, low-cut grass, and low nitrogen. Amending these issues can push clover out for good.

Hardy perennial clover loves the low nitrogen and compact conditions that often come with poor, infertile soils. But other factors also contribute to a clover explosion, including drought conditions, cool temperatures, under fertilization, and over-irrigation. You’ll need to evaluate all these elements when planning to kill off the clover.

Morning and late afternoon are the best times for watering new grass seed. The seed gets a healthy balance of water and sunlight, and the excess water evaporates. If you water the grass long after the sun goes down, the air is too cold, and there's no sun to make excess water evaporate. This keeps the grass damp for too long, increasing the chances of over-watering.

The easiest way to rough up soil to accept grass seed and provide the best opportunity for its growth is to make several passes over the area with a garden tiller and rake away the loosened vegetation and debris. However, in some cases, very hard ground may require using a shovel or pick to break up pieces into smaller chunks that the tiller can handle more easily.

You can, like you can put too little down. Sowing too much grass seed can create competition between the seeds for resources (light, water, nutrients) and the seedlings could struggle to grow. When you sow too few, your lawn will come in thin. Your seed product has a recommended seeding rate, so use that as your guide.
