"After reading positive reviews on Google I contacted Stephen for an estimate. He sold himself and company well so I hired him for a major project on our new construction. His work included paver installation, laying gravel, curbing, sprinklers, low voltage landscape lighting, and sod. On November 28 he guaranteed the work to be done by December 15 (except sod). On April 16 we entered into an agreement to void the contract with a reduction of cost to compensate for the work not completed. Over the 4 plus months I received many excuses why he could not do things, many no shows for days he committed to work, and a lot of less than truthful information. I could go on but I think the 4 months’ delay and the list of work that I need to finish the job speaks for itself. The low voltage lights are not installed, the sprinklers were not set and had no flow nozzles in them, 3/4 of the sprinklers pop up at an angle and need to be reburried, the pavers are scratched because he didn’t use a pad on the compactor, no pressure reducer or filter on the drip irrigation, drip irrigation runs not attached to a water supply, and solenoid valves not connected to the timer."

Lawn Fertilization and Treatment questions, answered by experts

Yes, you can typically combine liquid aeration with other lawn treatments. However, follow the specific product's instructions and consider the compatibility of treatments. In most cases, liquid aeration can complement fertilization, overseeding, or weed control programs. Combining treatments strategically can address multiple aspects of your lawn's health and appearance simultaneously. Always read and adhere to the guidelines provided by the product manufacturers to ensure safe and effective application.

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.

Most businesses schedule services weekly or biweekly to maintain a professional appearance and healthy lawn.

You don't want to over-fertilize your lawn because it can burn the grass and even kill it. Healthy soil usually requires two fertilization applications a year during the height of the growing season. This fertilization schedule typically starts at the start of fall and the end of spring, depending on the grass type and plants.

You can use a fungicide to help control powdery mildew, but you should apply it judiciously as it can damage soil health and persist in the soil. Most of the time, proper watering, surface drying, and limiting shade can control powdery mildew without needing harsher interventions. If you have a repeated problem with powdery mildew, you can also try planting a shade-resistant type of grass that will be less susceptible to the fungus.
