    3rd Year in and my lawn is *chef's kiss*

    This is the 3rd year in a row I have been using Sunday lawn care and my lawn looks 10x better than when I didn't use a lawn care plan or did it half-heartedly with store bough products. My grass is a deep green, thick and has weathered the lack of rain and abnormally high temperatures very well. I enjoy the schedule they provide and not needing to calculate things on my own. I am very happy and will keep using the service!

      Thornton, Colorado FAQs

      Common causes of dying grass in Thornton include drought stress from hot summers, improper watering practices, soil compaction, and disease pressure. Water deeply but infrequently in early morning, maintain proper mowing height at 3-4 inches, and avoid overwatering which can lead to fungal issues in our climate.

      For Thornton's climate, here's the optimal lawn care schedule:

      Early Spring (March-April): First fertilizer application, pre-emergent weed control Late Spring (May): Mow regularly, spot treat weeds Summer (June-August): Regular deep watering, maintain 3-4 inch mowing height Fall (September-October): Fertilize, overseed, aerate Winter (November-February): Minimal maintenance, occasional watering during dry spells

      Keep mowing height higher in summer to protect roots from heat stress. Water deeply 2-3 times per week rather than frequent light watering.

      Traditional lawn care services in Thornton typically cost $45-75 per visit, averaging $150-200 monthly during growing season. Sunday's custom lawn plans start at $55 for the season, with multiple shipments of fertilizer and optional add-ons for weed/pest control and grass seed. Plans include soil testing and expert support.

      For Thornton's semi-arid climate, maintain a healthy lawn by:

      1. Water deeply 2-3 times per week in early morning
      2. Mow at 3-4 inches height
      3. Apply fertilizer in early spring and fall
      4. Test soil to identify nutrient needs
      5. Address weeds through spot treatment
      6. Aerate annually in fall to reduce soil compaction
      7. Overseed thin areas in early fall

      This approach promotes deep root growth and drought resistance while minimizing water waste and maintenance needs.

      Professional lawn care can be worth it in Thornton, but it's not always necessary. Sunday's customized lawn plans offer a more affordable DIY alternative, starting at $55 per season versus $150-200 monthly for traditional services. You get expert guidance, soil testing, and perfectly timed fertilizer deliveries while maintaining control of your lawn care.

      In spring (March-April), apply a balanced fertilizer to support new growth. Spot treat any emerging weeds. Water 1-2 times per week as temperatures warm up. Keep grass height at 2.5-3 inches for initial spring mowing. Test soil to identify specific nutrient needs for the growing season.

      Professional lawn care services in Thornton typically charge based on lawn size, ranging from $45-75 per visit. Sunday's custom lawn plans offer a more affordable option starting at $55 per season, with cost varying by lawn size and selected options like weed control or grass seed.

      Professional lawn care services in Thornton save time and provide expertise, but can be costly at $150-200 monthly. Sunday offers a more budget-friendly alternative starting at $55 per season, providing custom fertilizer, soil testing, and expert guidance while letting you maintain control of application timing and methods.

      How to grow grass in Thornton, Colorado

      Most common grass type in Thornton Cool-season grasses
      Best way to grow grass in Thornton Seeding
      Recommended grass species for Thornton lawns Kentucky bluegrass, perennial ryegrass, tall fescue
      When to start growing grass in Thornton Spring: May 15 to June 5; Fall: September 18 to October 9

      Lawn care in Thornton, Colorado centers around cool-season grasses like Kentucky bluegrass, perennial ryegrass, and tall fescue. These grass types grow best when seeded during two key windows: mid-May to early June, or mid-September to early October. Fall tends to be the most successful time for grass seeding in Thornton due to cooler temperatures and lower weed pressure.

      For the best results with your Thornton lawn care:

      1. Choose grass seed that matches your yard conditions
      2. Time your seeding project during the recommended windows
      3. Keep newly seeded areas consistently moist
      4. Mow at 3-4 inches once grass reaches proper height

      The cool semiarid climate of Thornton means your grass seed needs steady moisture to germinate and establish. Plan to water lightly several times per day for the first few weeks after seeding. Once seedlings reach 2 inches tall, reduce watering frequency but water more deeply to encourage deep root growth.
