  • Late Winter
  • Early Spring
  • Spring
  • Early Summer

  • Fall
  • Winter

Round 1 (Jan-Feb)

Soil Enhancer

Your lawn starts the year strong with under-the-surface soil amendments that address the challenges of clay-heavy and compaction-prone Texas soil.
 
We apply humic acid to boost water retention, increase the availability of essential nutrients, improve soil structure, and stimulate the growth of beneficial soil microorganisms.
 
Additionally, we apply a pre-emergent treatment to target any lingering late-germinating weeds.
 
With every visit, we control weeds by spot-treating them using a specially formulated solution that can handle even the toughest Texas weeds.

Round 2 (Feb-Mar)

Revitalizer & Weed Barrier

At this stage, we ensure your lawn gets the nourishment it needs with our custom-blended fertilizer containing bio-nutrients. We also apply pre-emergent weed control to prevent weeds from germinating and sprouting in your lawn. 

  • Quick and slow-release fertilizers encourage your lawn to grow thicker at a steady, healthy rate.
  • Nitrogen supports spring growth by boosting vertical development and enhancing that vibrant green color.
  • Pre-emergent weed control for Bermuda and Buffalo lawns helps manage aggressive spring weeds.
  • Potassium promotes strong, deep root systems for long-term lawn health.
  • For St. Augustine lawns, we add sulfur to balance the soil’s high pH levels.

Our team will also spot-treat common lawn issues like lawn insects and diseases.

Round 3 (Mar-Apr)

Spring Color Burst & Growth Enhancer

During spring, grasses start to grow vigorously. We support their healthy growth on your lawn using nitrogen, a primary nutrient required for thicker, lusher, and greener lawns. 

Spring to early summer is also when beetle eggs hatch into grubs. We apply high-quality, long-lasting grubworm treatment once annually, between March and November, to protect your lawn from these root-damaging pests. 

With our weed and grub control treatments as well as our lawn fertilization services in San Antonio, TX, you can be confident that your lawn will stay green and healthy throughout spring.

Round 4 (Apr-Jun)

Stress Reliever

Summer in Texas means lots of scorching hot days. Excess heat stresses lawns, so to counteract its effects and fortify your turf, we apply the following: 

  • Nitrogen: Supports consistent stolon growth while reducing the chances of lawn “burn” damage
  • Fulvic Acid: Along with essential nutrients, fulvic acid conditions the soil, preparing it for warmer temperatures.
  • Weed Treatment: Targets and manages grassy weeds 

Spot Treatment: As-needed treatments for broadleaf weeds, fungi, and harmful insects

Round 5 (Jun-Jul)

Rejuvenator 

Too much heat can cause San Antonio lawns to wilt and become stressed, leaving them vulnerable to diseases, pests and thinning. We provide lawn fertilization services for Waco lawns that help them withstand the Texas heat and stay lush and healthy. These involve applications of: 

  • Slow-release Liquid nitrogen: Keeps grass green for longer without burning 
  • Humic and Fulvic Acid: Reduces turf heat
  • Organic Matter: Amends soil for better moisture retention and nutrient availability 

As always, we apply spot treatments for broadleaf weeds as well as treat lawn insects and turf disease.

Round 6 (Jul-Sep)

Recovery 

Our new slow-release liquid fertilizer keeps your lawn green and healthy throughout summer. This product supports microbial activity and provides steady nourishment to the soil.  We also apply: 

  • Humic and Fulvic Acid: Reduces thatch as well as improves water retention
  • Slow-release Liquid Nitrogen: Ensures long-lasting, healthy green color

As with every visit, we provide spot treatments against broadleaf weeds, turf disease and lawn insects whenever necessary.

Round 7 (Sep-Oct)

Harmonizer & Weed Barrier

When the chill enters the air, we prepare your lawn for the colder months ahead. Our focus during fall is to restore your lawn from surface-level stress while keeping weeds in check below the surface.

  • We add microorganisms to boost the roots’ ability to hold onto nutrients.

For Bermuda Lawns:

  • A small dose of nitrogen revives areas hit by summer issues like drought, disease and pests.
  • Our six-month weed control barrier blocks weeds before they can even sprout.

For St. Augustine/Zoysia Lawns:

  • Nitrogen keeps St. Augustine growing strong.
  • A light pre-emergent treatment tackles weeds without damaging the roots.

Round 8 (Nov-Dec)

Winter Soil Conditioner

During winter, grass goes dormant, but the roots and soil still need nourishment and care. We continue providing lawn fertilization services for San Antonio, TX, lawns during this time. 

We use: 

  • Potassium: Helps stressed areas bounce back faster from drought and reduces damage in the winter
  • Sulfur: This tackles high pH levels caused by limestone and local water.
  • Magnesium: This essential macronutrient keeps your lawn strong.

We’ll also spot-treat any broadleaf weeds, insects, or lawn diseases as needed.

FAQS

Question: What is the best weed control?
Answer: Controlling weeds is an ongoing battle and not a “one-and-done” event! Weeds have the ability to grow anywhere there’s room and consequently, they’re everywhere. Weed seeds come in abundance and from many sources. Additionally, they have the ability to lay dormant in the soil for years before germinating. When actively growing, weeds produce thousands of seeds per plant. As a result, weeds disperse those seeds throughout the season.
 
Here are some tips we advise:
 
1. Know what you’re working with. Different types of weeds require different treatments.
2. Mow often. Despite the concern that mowing can spread weed seeds, it’s more beneficial to the health and density of your lawn to mow frequently. By having a thick, full lawn you essentially help “crowd out” the weeds. Correspondingly, weeds grow when there is space for them and a thick lawn reduces available space for the weeds to grow in.
3. Apply a pre-emergent in the fall and spot-treat weeds throughout the year to help grow healthy turf and reduce weeds.
4. Coupled with those other tips, follow our watering guidelines to nurture your lawn and stop weeds in their tracks.
 
Here are some resources you may find helpful to maintain a weed-free lawn:
 
Question: Why do you do 8 lawn applications? Answer: There are three reasons! 1st, the exact timing based upon what the soil needs and the weather. 2nd, We apply lower doses more frequently. This produces superior results, is better for your turf, soil, and environment. And 3rd, it enables you to request service calls and in-between application treatments to ensure you are 100% satisfied!
Question: Do I have to buy the entire lawn care program? Answer: No, you don’t! You can purchase “a la carte” treatments. However, to receive service calls between regularly scheduled applications, we require a minimum of a 6 application program.
Question: Is there a contract for the fertilization and weed control program? Answer: No, there isn’t! We do not believe in requiring or tying a customer to an annual contract.
Question: What should I expect with my first lawn fertilizer service?
Answer: Your application will be scheduled out 3 to 5 business days after our first discussion with you
 
You do not need to be home to receive a lawn application; we’ll leave our notes at your front door
