"5 stars! Eric has been so responsive, professional, hard working and honest. We were looking for lawn mowing, weeding and mulching and Eric provided detailed quotes quickly...and his pricing was very competitive with other businesses. On work days Eric and Trey show up early and work non-stop until the job is done. The results look fantastic -- and they always make sure to clean up. Most importantly, Eric is honest -- when a job was finished faster than expected and less material was used he discounted the bill accordingly. We have been so pleased with Leeds we are going to also use them for fertilizing and weed control going forward."

"I recently hired Sanchez Brothers to handle trimming, shrub removal, and a full clean-up of my backyard, and I couldn’t be more pleased with the results. From the very beginning, their customer service stood out, they were quick to respond, professional in their communication, and made sure they fully understood what I wanted done. The team arrived on time, well-prepared, and got right to work. They were incredibly efficient and hardworking, carefully trimming and removing overgrown shrubs while keeping the surrounding areas neat and undisturbed.

Lawn Fertilization and Treatment questions, answered by experts

Water regularly, avoid heavy foot traffic, and clear debris promptly to support lawn health.

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.

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start. 

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

Because it’s native to the central United States and Canada and is drought-tolerant, it typically is not difficult to grow. It requires very little maintenance and minimal watering beyond rainfall. Its hardy nature and unique look make it a favorite choice among people living in the western United States and other dry regions of the country.
