"Crooks…..save your money….had ants coming in my front door in my brand new house. They “dusted” and “baited” outside so they said and when the problem got worse and I called and they blamed me for issue not working because I killed the ants.

Lawn Fertilization and Treatment questions, answered by experts

One of the best ways to soften your grass and prepare it for planting grass seed is aeration. Aerating your lawn will loosen up compacted soil and facilitate a more even balance of nutrients from root to topsoil. We recommend using core aeration methods for the most effective soil-loosening results.

The safest method to avoid killing your turf grass is hand pulling Johnsongrass. You can also apply vinegar for a safer herbicide, but it will still burn your lawn if it gets on it.

Yes, many professionals offer non-toxic and environmentally safe pest control solutions.

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.  

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