"DO NOT hire Dan Ford aka Dan the Handyman. I hired him to install a stone walkway and it is a complete disaster. The workmanship is terrible. The walkway is falling apart, breaking and lifting and is a trip hazard. I had to take him to court to get my payment refunded. I was awarded the judgment, but Dan Ford has NOT paid. I ended up having to file a transcript of judgment with the County Court and have a lien placed on him and his business. He still has NOT paid. Do NOT hire Dan Ford aka Dan the Handyman."

Lawn Fertilization and Treatment questions, answered by experts

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

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. 

Yes—lawn renovation can turn your lawn from damaged to healthy in one month or less. You should also consider lawn renovation an investment in your home’s future. Not only will a lawn renovation ensure that you have a beautiful, healthy, and thriving lawn, but when it comes time to sell your home, the curb appeal will increase your home’s value.

A lawn that suddenly and quickly turns yellow is typically the result of a dramatic change in the grass's environment. Heavy rainfall can dilute soil nutrients, rapidly yellowing the grass, and dull lawn mower blades can dry out and damage the grass in a short time. Over-fertilizing can yellow a lawn within a matter of days. 

Before you put down grass seed, you should cultivate your soil or add two inches of topsoil. You should also put down fertilizer at the same time as your seed to prompt healthy growth. Be sure to water after you put down grass seed, especially for the first two weeks.
