"Hard working individuals that totally exceeded expectations in every possible way. As an example, I moved a trailer for them so they could park their truck next to the gate and when they completed the job they put the trailer back. This is customer service that you never see anymore. They removed limbs from my trees and when they were completed it was not one leaf left on the lawn. Amazing job"

"We had another company install our sprinkler system 3 years ago and it wasn't done correctly. We've given many times to correct it and they couldn't. Bryan from this company came out and immediately knew how to resolve all the problem spots and fix the heads to spray how they needed. Not only is he excellent at his job his customer service is awesome. He went above and beyond to make sure we were comfortable, happy and understood the best way to manage our lawn. This company is blessed to him on their team!!"

Lawn Irrigation FAQs, answered by experts

First, you should figure out whether you have dormant or dead grass. Dead grass won’t come back, so you’ll have to reseed if you’re hoping for a lush lawn. However, grass can go dormant if it hasn’t received enough water or if temperatures are too cold. If it’s still decently warm outside, you can revive dormant grass by watering it. But if it’s mid-January in New England, for example, you’ll need to wait until the weather warms up again. If you want to keep grass green in winter, consider a grass like Kentucky bluegrass, which maintains its color year-round.

Yes, some grass will germinate in two weeks or less but it will take several weeks more before it is established enough to walk (or nap) on. To grow grass quickly, follow the tried-and-true-steps carefully, starting with choosing a cool- or warm-season grass seed that flourishes in your home’s climate.

Provided you're using an appropriate starter fertilizer for grass seed, you can put down seeds and fertilizer at the same time. However, putting them down separately, one after the other, on the same day will help to avoid over- or under-applying the lawn food. Avoid using a fertilizer with weed control elements, as these will likely keep the grass seeds from starting.  

Buffalo grass is not a dense grass, so weeds can grow between the buffalo grass plants. However, as long as you don’t overwater your lawn, weeds have a hard time growing. If you do notice weeds, you can use granular herbicides that are safe for buffalo grass in early and late summer.

While hydroseeding is typically meant for bare soil, it is possible to hydroseed over an existing lawn with some adjustments. For the new seed to germinate and thrive, it needs good seed-to-soil contact. Without it, most of the seed may not take root and will die. To improve your chances of success when repairing a patchy area, mow any existing grass as low as possible and loosen any exposed soil before application. It is also recommended to use a finer mulch mixture when spraying, as this will help the seeds reach the soil and root without suffocating the existing grass.
