Spring brings new life to McKinney lawns after winter dormancy. The right lawn care strategy makes a big difference for your yard’s health and appearance. Homeowners in McKinney face unique challenges due to our North Texas climate. This guide provides season-specific advice to help your lawn thrive throughout the year.
Understanding McKinney’s Unique Climate
McKinney sits in a transition zone between cool and warm-season grass regions. Our climate features hot summers, mild winters, and unpredictable spring and fall weather. These conditions affect when and how you should care for your lawn.
McKinney receives about 42 inches of rain per year, with May typically being the wettest month. Summer temperatures often exceed 95°F, while winter can bring occasional freezes. This climate pattern demands a tailored approach to lawn care.
Best Grass Types for McKinney
The right type of grass forms the foundation of a healthy lawn. For McKinney’s climate, these grasses perform best:
- Bermuda grass: Handles heat and drought well, needs full sun
- St. Augustine: Tolerates some shade, needs more water
- Zoysia: Good middle ground with moderate shade tolerance and drought resistance
- Buffalo grass: Native Texas option that requires minimal water and maintenance
Most McKinney neighborhoods, like Stonebridge, Tucker Hill, and Trinity Falls, feature these grass types due to their success in our local conditions.
Year-Round Treatment Calendar for McKinney Lawns
Spring (March to May): Waking Up Your Lawn
Spring lawn care focuses on preparing your grass for the growing season after it comes out of winter dormancy.
March Treatment (Round 1)
- Apply pre-emergent herbicide to prevent crabgrass and other summer weeds
- Light fertilization with nitrogen to kickstart growth
- Begin mowing when grass reaches 2-3 inches tall
- Check the irrigation system for winter damage
April Treatment (Round 2)
- Apply the second round of pre-emergent herbicide
- Spot-treat any early-season weeds
- Fertilize with balanced nutrients (nitrogen, phosphorus, potassium)
- Adjust mowing height to 2.5-3 inches for most grass types
When should I fertilize my lawn in McKinney?
The best time for spring fertilization in McKinney is late March through April, when soil temperatures consistently reach 55°F. This timing helps warm-season grasses like Bermuda and St. Augustine make the most of nutrients as they enter active growth. Avoid fertilizing too early, as nutrients may wash away before grass can use them.
May Treatment (Round 3)
- Apply post-emergent weed control for broadleaf weeds
- Begin regular watering schedule (early morning is best)
- Monitor for pest issues as temperatures rise
- Consider a soil test to check nutrient levels
Walking through Towne Lake Park this spring, I noticed how quickly lawns green up when they receive proper early-season care. My neighbor on Virginia Parkway waited until May to start lawn care, and the difference between our yards was striking.
Summer (June to August): Surviving the Heat
Summer lawn care focuses on helping your grass withstand McKinney’s intense heat and occasional drought conditions.
How do I prepare my lawn for Texas summer?
Prepare your McKinney lawn for summer by:
- Raising your mowing height to 3-3.5 inches to shade soil and roots
- Watering deeply but infrequently (1-1.5 inches per week)
- Avoiding fertilization during the hottest periods
- Treating for chinch bugs and other summer pests
- Applying mulch to beds to reduce water evaporation
June to July Treatment (Round 4)
- Apply summer-formula fertilizer with iron for green color without excessive growth
- Treat for grubs and other summer pests
- Continue post-emergent weed control as needed
- Water deeply 2-3 times per week instead of daily light watering
During last summer’s heatwave, lawns in Craig Ranch that followed these practices stayed green, while others turned brown. The difference came down to watering depth and timing rather than frequency.
August Treatment (Round 5)
- Apply light fertilizer to support recovery from summer stress
- Continue pest monitoring and treatment
- Begin preparing for fall treatments
- Check for signs of fungal disease from summer humidity
Many McKinney residents struggle with brown patches in late summer, particularly in areas near Wilson Creek where humidity remains high. Proper watering timing (early morning only) helps prevent this issue.
Fall (September to November): Recovery and Preparation
Fall lawn care focuses on helping your grass recover from summer stress while preparing for winter dormancy.
September to October Treatment (Round 6)
- Apply fall fertilizer with higher potassium to strengthen roots
- Core aeration to reduce soil compaction
- Overseed thin areas (mid-October is ideal)
- Control fall weeds before they establish
The rolling terrain of Adriatica Village shows how proper fall care impacts spring performance. Homes that aerate and overseed in fall consistently have the first green lawns in spring.
November Preparation
- Final mowing slightly lower than summer height
- Apply pre-emergent for winter weeds like henbit and chickweed
- Reduce watering frequency as temperatures drop
- Clean up leaves to prevent lawn suffocation
Winter (December to February): Protecting Dormant Turf
Winter lawn care focuses on protecting your dormant grass from damage while preparing for spring.
December to February Maintenance
- Limit foot traffic on dormant lawns, especially during freezes
- Continue leaf removal
- Spot-treat winter weeds
- Plan spring lawn care strategy
After the 2021 freeze, lawns in McKinney that received proper winter protection recovered much faster than those that were neglected. Even in dormancy, your lawn needs some attention.
McKinney Microclimate Considerations
McKinney’s topography creates several microclimates that affect lawn care timing:
- Eastern McKinney (near Lake Lavon): Higher humidity and slightly milder temperatures mean earlier spring green-up, but more disease pressure
- Western McKinney (Highway 75 corridor): Slightly warmer with more urban heat effect, requiring adjusted watering schedules
- Northern areas (near Wilmeth Road): Often experience first frost earlier in fall
- Southern neighborhoods (near the Allen border): Typically warmer by 1-2 degrees than northern areas
Residents in Historic Downtown McKinney often need to water more frequently than those in newer developments, such as Auburn Hills, due to established tree canopies and different soil profiles.
Water Conservation in McKinney
McKinney often implements water restrictions during the summer months. Plan your lawn care strategy with these tips:
- Install smart irrigation controllers that adjust to weather conditions
- Water on your designated days before 10 AM or after 6 PM
- Consider drought-resistant native plants for part of your yard
- Apply a quarter-inch layer of compost annually to improve soil water retention
The Heard Natural Science Museum showcases native plants that thrive with minimal supplemental water, providing inspiration for water-conscious homeowners.
DIY vs. Professional Lawn Care
While many McKinney homeowners handle basic lawn maintenance, professional services provide significant benefits:
- Access to commercial-grade products is not available to homeowners
- Precise timing based on soil temperatures rather than calendar dates
- Customized treatment plans for your specific grass type and soil conditions
- Time savings during busy seasons
