"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

Yes, grass will regrow after forestry mulching, but the timeline depends on soil conditions, mulch thickness, and existing seed banks. The nutrient-rich mulch left behind helps retain moisture and improve soil health, encouraging regrowth. However, if the mulch layer is too thick, it may block sunlight and slow grass germination. For faster results, you can rake excess mulch, aerate the soil, and plant the new grass seeds.

Having a luscious lawn won’t take a century to grow with hydroseeding—most hydroseed lawns sprout within 7 to 14 days. Once the new grass is about 4 inches tall, which is about six weeks after the installation, it’s ready to mow. After the initial mow, keep foot traffic at a minimum for another four weeks to solidify the rooting system.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

Overseeding typically involves spreading grass seed either manually or with a machine that sprays the grass seed out and onto the soil. With overseeding, the grass seeds sit on the soil, and some may fall deeper into the soil if you aerated beforehand. With power seeding, a machine cuts narrow rows into the soil and pushes the grass seeds directly into the soil.

This depends on the type of grass seed, as some types do better in different environmental conditions. Cool-season grasses go dormant during the summer months when the soil temperature exceeds 65 degrees Fahrenheit. Once exposed to regular doses of heat, the germination rates decline, with seedling death not far behind. 

As for warm-season seeds, they come from tropical parts of the world and thrive in heat. They actively grow in warm air temperatures between 70 and 90 degrees Fahrenheit, and they prefer soil temperatures between 65 and 70 degrees Fahrenheit. Once temperatures dip and frost rolls in, if you don’t store them properly, warm-season grass seeds will die quickly.
