A successful lawn in Frisco doesn’t come from occasional effort; it comes from following a consistent seasonal rhythm that matches the North Texas climate. A Frisco lawn care service helps homeowners stay ahead of fast-changing conditions like summer heat, water restrictions, and grass-specific growth cycles for Bermuda and St. Augustine. When you know what to do each month, from fertilizing in early summer to adjusting mowing height during peak heat, your lawn stays healthier and more resilient throughout the entire growing season.

Instead of reacting to brown spots, patchy growth, or weed outbreaks after they appear, a structured monthly plan helps prevent most of those problems in the first place. It turns lawn care into a predictable system rather than a series of urgent fixes, giving you a greener yard with less stress and fewer surprises.

Bermuda grass: Common Bermuda or hybrid Bermuda (Tifway, TifTuf). Loves full sun, tolerates Texas heat, goes dormant and brown in winter, and recovers fast in spring. Aggressive grower in summer. Most home lawns and most newer subdivisions.

St. Augustine grass: Floratam, Raleigh, or Palmetto cultivars. Tolerates shade better than Bermuda, holds green color longer into fall, weaker against heat stress and drought. Common in older neighborhoods and shaded yards.

Knowing which grass you have determines the schedule. If your lawn looks like coarse blades that lie flat, it is probably Bermuda. If it has wider blades that stand up and fold lengthwise, it is St. Augustine.

A small portion of Frisco lawns is Zoysia (denser, slower-growing, more cold-tolerant). Zoysia care is similar to Bermuda, with slightly longer mowing height.

May: spring transition and first feed

By mid-May, Bermuda is fully out of dormancy and growing aggressively. St. Augustine is fully green and starting to spread.

Mowing:

  • Begin weekly mowing
  • Bermuda: 1.5 to 2.5 inches
  • St. Augustine: 3 to 4 inches
  • Bag clippings only if the grass is overgrown; otherwise, mulch them in for nitrogen

Fertilizing:

  • First feeding of the year if you did not do an April pre-emergent + fertilizer combo
  • Slow-release nitrogen 4-1-2 ratio (e.g., 21-7-14 or similar)
  • Apply 0.5 to 1 lb of nitrogen per 1,000 sq ft
  • Bermuda tolerates higher rates than St. Augustine

Watering:

  • 1 inch of water per week (rainfall + irrigation combined)
  • Two deep waterings per week are better than five shallow ones
  • Adjust irrigation controller for May start (most controllers have a seasonal multiplier)

Weed control:

  • Pre-emergent should already be down (March or early April)
  • Spot-treat broadleaf weeds (dandelion, henbit, clover) with a selective herbicide
  • St. Augustine cannot tolerate 2,4-D in heat; use atrazine or a product labeled for St. Augustine

June: summer fertilization and grub control

June is peak growth for Bermuda. St. Augustine is also growing vigorously.

Mowing:

  • Continue weekly. Bermuda may need cutting twice per week in early June
  • Sharpen mower blades; dull blades shred grass and brown the tips
  • Always remove no more than 1/3 of the blade height per cut

Fertilizing:

  • Second application around mid-June for Bermuda
  • St. Augustine: lighter rate, 0.5 lb nitrogen per 1,000 sq ft
  • Iron supplement helps Bermuda green up without forcing growth

Grub control:

  • White grubs (Japanese beetle larvae, June bug grubs) hatch in late June
  • Apply imidacloprid or chlorantraniliprole-based grub control
  • Water in immediately after application
  • One application protects throughout the season

Watering:

  • Increase to 1 to 1.25 inches per week
  • Heat stress symptoms: blue-gray cast, footprint impressions stay visible
  • Water early morning (4 to 8 AM) for best efficiency

Insect monitoring:

  • Chinch bugs in St. Augustine cause yellow-then-brown patches in sunny areas
  • Sod webworms create irregular brown patches
  • Drench-and-flush test: mix 1 oz dish soap in 2 gallons of water, pour over a 1-square-foot suspect area, and count any insects that surface

July: peak heat survival

July is survival mode. Triple-digit days stress every lawn. The goal is to keep the grass alive, not push growth.

Mowing:

  • Raise the mower 1/2 inch higher than spring height
  • Bermuda: 2 to 3 inches
  • St. Augustine: 3.5 to 4 inches
  • Higher cuts shade the soil, reduce water loss, and improve drought tolerance

Fertilizing:

  • Skip July if Texas is in drought conditions
  • Fertilizer in extreme heat can burn grass
  • Resume in August if conditions cooperate

Watering:

  • 1.25 to 1.5 inches per week
  • Watch for water restrictions; many Frisco-area cities limit watering to 2 days per week in summer
  • Run irrigation in 2 to 3 short cycles per zone (e.g., 8 minutes, off, 8 minutes, off, 8 minutes), so water soaks in rather than running off

Weed control:

  • Most herbicides damage grass in temperatures above 90°F
  • Hand-pull weeds where possible
  • Spot-treat only stubborn weeds with care; check the label for temperature limits

Watch for:

  • Brown patches: could be an insect, a disease, or a hot spot from a sprinkler malfunction
  • Stop fertilizing damaged areas; let them recover

August: second fertilization and watering audit

August is the toughest month. Frisco often hits 100+ for weeks. Lawns brown out without irrigation.

Mowing:

  • Continue at the higher summer height
  • Cut less frequently (every 7 to 10 days) if growth has slowed from heat stress

Fertilizing:

  • Third application late August for Bermuda, only if rainfall has been adequate
  • Skip if your lawn is heat-stressed
  • St. Augustine: avoid August fertilization entirely; resume September

Watering audit:

  • Check sprinkler heads for breaks, mismatched spray patterns, and blocked sprays
  • Cup test: place 6 plastic cups in random spots, run irrigation for 15 minutes, measure water depth, calculate average to verify 1 inch per week target
  • Adjust the controller for any zones that are dry or overwatering

Pre-emergent for fall weeds:

  • Late August through mid-September is the window for fall pre-emergent
  • Targets cool-season weeds: poa annua, henbit, chickweed
  • Use a labeled pre-emergent (prodiamine, dithiopyr) for cool-season weed control

Other tasks:

  • Inspect for fungal disease: rust on Bermuda blades, gray leaf spot on St. Augustine
  • Treat with an appropriate fungicide if observed

September: fall transition prep

September signals fall transition. Cooler nights and shorter days slow growth.

Mowing:

  • Continue weekly, lowering height back to spring levels by late September
  • Bermuda: 1.5 to 2.5 inches
  • St. Augustine: 3 to 4 inches

Fertilizing:

  • Important application for both Bermuda and St. Augustine
  • 1 lb nitrogen per 1,000 sq ft
  • Promotes root development before dormancy

Aeration:

  • Best month for core aeration of Bermuda
  • Reduces compaction, improves water infiltration, and helps roots breathe
  • DIY rentals available, professional service $80 to $200

Watering:

  • Reduce to 1 inch per week or less as temperatures drop
  • Continue to monitor weekly, do not assume rain has covered it

Brown patch monitoring:

  • St. Augustine is highly susceptible to brown patch fungus in late September and October
  • Yellow-to-brown circular patches that expand
  • Treat preventively with a fungicide labeled for brown patch when nighttime temps drop below 70°F

October: winterizer and overseeding decisions

October is the last active month before dormancy.

Mowing:

  • Final mows of the season
  • Mulch fallen leaves into the lawn (free fertilizer) if leaf coverage is light
  • Bag heavy leaf coverage to prevent suffocation

Fertilizing:

  • Winterizer with higher potassium (e.g., 5-10-30 or similar)
  • Strengthens root systems for winter
  • Apply before the first hard freeze
  • Skip on St. Augustine in shade; risk of fungus outweighs benefit

Overseeding decision:

  • Frisco lawns can be overseeded with annual ryegrass for green winter color
  • Sown in mid-October at 5 to 10 lbs per 1,000 sq ft
  • Trade-off: lush winter color, but it can stress the warm-season grass in spring transition
  • Most Frisco homeowners skip overseeding and accept dormant brown winter Bermuda

Watering:

  • Dial back as rainfall returns
  • Continue to water deeply when needed; dormant grass still benefits from soil moisture

End of season tasks:

  • Drain and winterize the irrigation system before the first freeze (if pipes are vulnerable)
  • Sharpen mower blades for next year
  • Clean tools and store fuel-treated equipment

Watering schedule and water restrictions

Most Frisco-area cities (Frisco, Plano, McKinney, Allen) impose water restrictions in summer. Typical rules:

  • 2 days per week watering
  • No watering from 10 AM to 6 PM
  • Even-numbered addresses one day, odd-numbered another
  • Some cities require Stage restrictions during drought

Efficient watering approach:

  • Water in the morning (4 to 8 AM)
  • Use cycle-and-soak: split each zone’s runtime into 2 or 3 cycles separated by 30 to 60 minute soak periods
  • Adjust seasonally; controller smart features, or a manual adjustment each month works

Smart controllers (Rachio, Hunter Hydrawise, Rain Bird ESP-LXIVM) can save 20 to 40% on water by adjusting based on weather and soil. Worth the $200 to $400 investment for larger lawns.

Mowing height by grass type

Grass Spring height Summer height Cut frequency
Common Bermuda 1.5-2 in 2-2.5 in Weekly
Hybrid Bermuda 0.5-1.5 in 1.5-2 in 2x weekly peak
St. Augustine 3-3.5 in 3.5-4 in Weekly
Zoysia 1-2 in 2-2.5 in Weekly

Key rules:

  • Never remove more than 1/3 of the blade in one cut
  • Sharp blades only; dull blades shred grass and brown tips
  • Mulch clippings back into the lawn unless excessive

Final Thoughts

A healthy Frisco lawn isn’t built in a single month; it’s managed through steady, seasonal decisions that respond to heat, rain, soil, and grass type. When you follow a simple rhythm of mowing, watering, fertilizing, and seasonal timing, both Bermuda and St. Augustine lawns become far more resilient to North Texas extremes. The goal isn’t perfection every week, but consistency across the entire growing season.

When conditions shift or problems start showing up, patchy growth, discoloration, or water stress, it helps to step back and look at the bigger pattern instead of reacting to each symptom individually. That’s where experience and timing matter most, and why many homeowners rely on structured seasonal guidance from Total Lawn Care to keep their yards healthy, predictable, and easier to maintain year after year.
