"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. I appreciated how they paid attention to detail and followed through on every request I made. The clean-up afterward was just as impressive."

Lawn Fertilization and Treatment questions, answered by experts

It depends on the type of grass and the condition of your lawn. We advised you to fertilize your lawn at least twice per year. However, warm-season grasses and nutrient-deficient lawns may need to be fertilized up to four times a year. Remember, you don't want to over fertilize either, so soil testing can help to determine if your lawn lacks nutrients and if it’s ready for another application.

Costs depend on property size, service frequency, and additional tasks like aeration or overseeding.

You free up your weekends, as pros often conduct mowing and maintenance efficiently and without disrupting your schedule.

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.

You should fertilize your lawn after it has grown at least two inches or after your second mow (usually in March or April). Applying fertilizer too early can feed your weeds and cause them to grow stronger, too. You should water your lawn two to three days before you apply fertilizer to ensure the soil absorbs it.
