Seasonal Lawn Fertilization in Houston, Timed to Your Grass
01 Free On-Site Assessment
We start with a free visit and a written quote. We check your grass type, look for yellowing and weed pressure, and can factor in a soil test so we feed only what your lawn actually lacks. A basic AgriLife soil report is inexpensive and takes the guesswork out.
02 Green-Up Timing, Not the Calendar
We hold the first spring nitrogen round until your grass is actively growing and has been mowed a couple of times, usually mid-March into April on the Gulf Coast. Feeding dormant turf is wasted and can feed weeds instead. That is why our lawn fertilization program runs in seasonal rounds.
03 Pre-Emergent Weed Control
We time spring pre-emergent before soil temperatures stay above about 55 degrees, usually late February into early March, to stop crabgrass, dallisgrass, and doveweed before they sprout. A fall round targets winter weeds like annual bluegrass. Pre-emergents only work before weeds germinate, so the timing is everything.
04 Feed, Correct, and Spot-Treat
We split nitrogen across the season and stay within the recommended annual amount rather than dumping it all at once. When we see yellow new growth, we treat it as iron chlorosis and correct it with foliar or chelated iron, not more nitrogen. We spot-treat weeds that break through with the right product for that weed.
05 Recurring Rounds & Monitoring
Your lawn gets scheduled rounds through spring, summer, and fall, with the last nitrogen going down well before the first frost. We watch how the grass responds and adjust each round. This keeps lawns green and weed-free from Katy to Sugar Land all season.

Why Our Fertilization Program Works in Houston
A bag of fertilizer from the store cannot read your soil or time your weeds. With 20+ years in Houston and 500+ projects completed, our in-house team knows how alkaline clay behaves and which weeds show up when. We match the product and the timing to your actual lawn.
Houston Lawns
We Fix Yellowing the Right Way
When St. Augustine yellows between the veins on new growth, that is usually iron chlorosis from high-pH clay, not a nitrogen shortage. We correct it with foliar or chelated iron that works in alkaline soil. Piling on more nitrogen would not green it up and could waste your money.
Weeds Stopped Before They Start
Our weed control is scheduled around Houston’s local weed calendar, with pre-emergent rounds timed to soil temperature in spring and fall. Stopping crabgrass and annual bluegrass before they germinate beats spraying mature weeds later. A single blanket spray simply underperforms here.
Right-Sized, Not Overfed
We split nitrogen across the season and keep totals within the recommended annual limit, using soil-test data to right-size each round. That protects your lawn, saves you money, and keeps excess fertilizer from running off. Licensed and insured, we handle every application in-house.
Lawn Fertilization & Weed Control Tuned to Houston Soil
Houston lawns are warm-season grasses, so we feed by green-up and soil temperature rather than a fixed date. We soil-test where it helps, apply only the nutrients your grass lacks, and split nitrogen so we stay within the recommended annual amount. Right-sizing each round protects the lawn and avoids the waste that comes from overfeeding.
Our high-pH, alkaline clay soil ties up iron, which is why St. Augustine here is so prone to yellowing. We read interveinal yellowing on new growth as iron chlorosis and treat it with foliar or chelated iron that actually works in alkaline soil. We also read indicator weeds, like clover in a thin lawn, as a sign to correct the underlying fertility, not just spray.
Houston yards drain to bayous that feed Galveston Bay, so how we apply matters for more than your lawn. We keep granules off pavement and away from storm drains, avoid applying right before heavy rain, and favor slow-release, split applications. That way your grass gets fed, weeds stay down, and the fertilizer does not wash off. Lawns from Cypress to Pearland stay greener with less waste.

Frequently Asked Questions
How much does lawn fertilization cost in Houston?
Lawn fertilization service cost depends on your yard size, the number of rounds, and whether you add weed control, iron treatments, or a soil test. Because our clay and grass types vary, we give a free on-site quote in writing rather than a flat rate. A full seasonal program usually costs less over the year than chasing problems with one-off treatments. After 20+ years and 500+ Houston projects, we size your lawn quickly and give you an honest number up front.
When should pre-emergent weed control go down in Houston?
Timing is everything with pre-emergent. Spring pre-emergent should go down before soil temperatures stay above about 55 degrees for several days, usually late February into early March here, to stop crabgrass, dallisgrass, and doveweed before they sprout. A fall round in September into early October targets winter weeds like annual bluegrass. Pre-emergents only work before weeds germinate, so we time rounds to local soil temperature rather than the calendar, which is far more effective than spraying mature weeds later.
Which weeds are common in Houston lawns?
Because the Gulf Coast stays hot and humid most of the year, weed pressure is nearly year-round. Warm-season weeds include doveweed, sandbur, crabgrass, dallisgrass, spurge, and nutsedge, which has a triangular stem and pushes up as soil warms in late spring. Cool-season weeds include annual bluegrass, henbit, chickweed, and clover. Different weeds need different products and timing, so our weed control targets warm-season weeds in spring and summer and cool-season weeds in fall.
How often should I fertilize my lawn in Houston?
We fertilize in seasonal rounds, not one time. The first spring nitrogen waits until your grass is actively growing and mowed a couple of times, usually mid-March into April. We repeat through summer and put the last nitrogen down four to six weeks before the first expected frost. Feeding dormant turf is wasted and can feed weeds. Spacing rounds this way keeps the lawn fed steadily and stays within the recommended annual nitrogen amount for warm-season grass.
Why is my St. Augustine grass turning yellow?
In Houston, yellow St. Augustine is usually iron chlorosis, not a lack of nitrogen. Our alkaline clay soil sits at a high pH, which locks up iron so roots cannot take it in. The newest blades turn yellow while the veins stay green. Adding more nitrogen will not fix it and can waste money. We correct it with foliar or chelated iron that works in alkaline soil, and we factor the clay into product choice so applications actually green the lawn.
Does fertilizer runoff affect Houston’s bayous?
It can, which is why we apply carefully. Houston yards drain to bayous that feed Galveston Bay, and excess lawn fertilizer is a recognized source of nitrogen that can fuel algae in the Bay. State and AgriLife guidance is to soil-test and apply only what is needed, keep fertilizer off pavement and away from storm drains, and never fertilize right before heavy rain. We follow that: we right-size nitrogen, avoid applying before forecast downpours, and favor slow-release, split applications so the lawn gets fed and little washes off.
