Why It Matters
Lawn Weed Removal Done Right the First Time
Not all weed treatments are created equal. One of the most common and costly mistakes in lawn care is applying the wrong herbicide to the wrong grass type. St. Augustine and Bermuda grass each have very different chemical tolerances, and using the wrong product can wipe out an entire lawn. At Rendon & Son, our team knows exactly which herbicides are safe for your turf. We bring over 56 years of family knowledge to every yard we treat, from the high-density neighborhoods of Alamo Ranch to the residential streets of Helotes. When we pull up to your property, we are not guessing. We know the grass, we know the weeds, and we know how to get rid of them without causing damage.
Our Approach
Targeted Herbicide Application for San Antonio Lawns
Our professional weed treatment process starts with identifying what is growing in your yard and what type of grass you have. From there, we select the appropriate herbicide formulation, whether that is a pre-emergent to stop weeds before they sprout or a post-emergent to eliminate what is already there. We pay close attention to the specific sensitivities of St. Augustine grass, which can be easily damaged by chemicals formulated for Bermuda lawns. This level of care is what separates a knowledgeable local crew from a generic franchise operation. Every herbicide application is handled with precision so your grass stays healthy, green, and weed-free throughout the season. We serve homeowners and commercial properties across Northwest San Antonio, including Alamo Ranch and Helotes.
Built Into Every Visit
Weed Prevention Service as Part of Your Regular Lawn Care
Consistent weed prevention is far more effective than periodic emergency treatments. That is why our standard lawn maintenance package, starting at $65, includes targeted lawn weeding alongside mowing, edging, and blowing. By addressing weeds regularly, we keep them from establishing deep root systems that are harder to remove later. For homeowners in HOA communities like Alamo Ranch, staying on top of weeds also means staying in compliance with community standards and avoiding fines. We show up on schedule, Tuesday through Saturday, and we do not cut corners. After every visit, we send before-and-after photos directly to your phone so you can see the results even if you are at work. Reliable, transparent, and thorough: that is the Rendon & Son standard.
A Legacy of Local Expertise
56 Years of San Antonio Turf Knowledge Behind Every Treatment
Rendon & Son is not a new company trying to figure things out. Our roots go back to John's great-grandfather, who spent 56 years working San Antonio lawns from age 17 to age 73. That generational knowledge informs how we approach weed control, fertilization, and every other aspect of lawn health. We are a family-operated team, John, his father, and his brother, and our family name is on every job we complete. We work in Alamo Ranch, Helotes, and across the Northwest San Antonio corridor, and we treat every property like it belongs to a neighbor. If a particular treatment is not right for your lawn, we will tell you honestly rather than sell you something you do not need. That kind of integrity is what keeps our clients coming back season after season.
Common Questions
What San Antonio Homeowners Ask About Weed Control

  • Will your weed killer damage my St. Augustine grass?

    No. St. Augustine grass is chemically sensitive and can be severely damaged or killed by herbicides formulated for Bermuda lawns. Our team identifies your grass type before applying any product and selects a herbicide that targets the weeds without harming your turf. This is a common mistake made by less experienced crews, and it is one of the reasons we take chemical application so seriously. We have 56 years of family knowledge behind every treatment we perform.

  • Is lawn weeding included in your standard mowing package?

    Yes. Our standard lawn maintenance package, starting at $65, includes targeted lawn weeding along with mowing, edging, and professional blowing of all hardscapes. We address weeds as a routine part of every visit rather than treating it as a separate add-on. Keeping up with weeds on a regular schedule prevents them from developing deep root systems that become much harder to remove over time. The exact price may vary depending on the total square footage of your property.

  • What is the difference between pre-emergent and post-emergent herbicide treatments?

    A pre-emergent herbicide is applied to the soil before weeds sprout, creating a barrier that stops seeds from germinating. A post-emergent herbicide treats weeds that are already visible and actively growing in your lawn. The right choice depends on the time of year, the type of weeds present, and your grass variety. Our team evaluates your yard and recommends the appropriate treatment. In many cases, a combination of both approaches gives the best long-term results for keeping your lawn clean and weed-free throughout the season.

  • How will I know the weed treatment was completed if I am not home during the visit?

    We send before-and-after photos directly to your phone after every service visit. You will be able to see the condition of your lawn before we started and after we finished, giving you a clear visual record of the work completed. This photo verification process is a standard part of how we operate, not something you have to request. It keeps things transparent and gives you peace of mind without requiring you to be on-site.

  • Do you provide weed control for commercial properties in San Antonio?

    Yes. We service both residential homeowners and commercial properties across San Antonio, including in Alamo Ranch and Helotes. Commercial properties benefit from the same careful, grass-specific herbicide application we bring to residential yards. Maintaining clean, weed-free grounds is especially important for commercial curb appeal and for HOA-managed common areas. If you manage a commercial property and want to discuss a recurring maintenance plan, you can reach us at 210-789-8611 or by email at rendonandsonlawnservice24@gmail.com.

  • How often should I schedule weed control treatments for my San Antonio lawn?

    For most San Antonio homeowners, consistent weed management as part of a regular lawn maintenance schedule is the most effective approach. Because weeds grow quickly in the Texas climate, addressing them during each routine visit, rather than waiting for a major infestation, keeps your lawn in much better shape year-round. Our standard package includes weeding on every visit. If your yard has a significant existing weed problem, we can assess it during a quote and recommend a treatment frequency that fits your specific lawn conditions.
