billing is by the job. 10% off first cutting.

"Bryan the owner does not do what he says he'll do. He lied about when he was going to finish my retaining wall project. It has now been 8 weeks and it is still not done!!!! It has been 3 days since they have been to my house!!! He refuses to return my phone calls or emails. I am in the process of getting another contractor to finish the job. One contractor found a bow in the wall that might have to be replaced. This man is a home owner worst nightmare!!!!"

Lawn Fertilization and Treatment questions, answered by experts

Water daily, avoid heavy foot traffic, and mow when the grass reaches 3-4 inches.

It’s not required, but it is helpful if your goal is to produce new growth. Any fertilization should occur after the lawn is aerated and before the compost is applied. If you also plan to spread seed, you’ll want to do so after the fertilizer is applied and once the ground is damp, but not wet.

If you notice your grass is growing quickly and it’s hard to keep up, cut down on how much you water and fertilize it. Another helpful method is to mow the grass at the highest setting your mower will allow. Mowing at a higher setting slows grass growth since the blades won’t need to repair themselves as quickly if they’re kept at a longer length.

Sugar water helps the microorganisms in the soil break down nutrients, thus helping certain plants grow. In other words, it is okay to water plants with sugar water, but exercise caution and never rely on sugar when fertilizing your grass. Sugar is not plant food and, if applied too liberally, kills the plants you intend to help.

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.
