West Idaho is being hit by a hit wave right now, and like most homeowners, you may be concerned about your lawn and garden. If your grass is anything but green, the go-to response is to add more water. But that's not always the problem, especially if you have a sprinkler system and are watering routinely in the cool hours of the day.

In this post, A Superior Cut will help you troubleshoot your lawn and make the best decisions for your grass and water conservation. We’ll walk through the lineup of top lawn damage culprits, show what to look for, and give tips for combatting the problems so you can get back to enjoying your summer backyard activities
Weeds -
Weeds are more than just an eyesore; they actively compete with your grass for nutrients, water, and sunlight. In western Idaho, some of the most problematic weeds include:
1.Dandelions

2.Crabgrass
3. Clover
4. Chickweed
5. Common Mallow
6. Bindweed
7. Puncturevine (Goatheads)
8. Purslane
9. Thistle

What to look for: Keep an eye out for plants that don't match your grass in color, texture, or growth pattern. Many weeds will stand taller than your grass or have broader leaves.

How to combat it: For small infestations, hand-pulling can be effective. For larger areas, consider using a selective herbicide that targets weeds without harming your grass. Always follow the product instructions carefully. Prevention is key – maintain a thick, healthy lawn to crowd out potential weed invaders.

Pests -
Various critters can wreak havoc on your lawn, especially during stressful periods like heatwaves.

What to look for: Signs of pest damage include:
  • Brown patches
  • Chewed grass blades
  • Small holes in the lawn
  • Visible insects or grubs

Common lawn pests in West Idaho include grubs, chinch bugs, and armyworms.

How to combat them: Identify the specific pest before treatment. Many local garden centers can help with identification. Once identified, use appropriate pesticides or natural remedies. For example, beneficial nematodes can help control grubs naturally.

Soil - 
The quality of your soil plays a crucial role in lawn health.

What soil types are ideal vs. non-ideal for popular grass species:
  • Kentucky Bluegrass prefers well-drained, fertile soil with a pH between 6.0 and 7.0.
  • Fescues can tolerate a wider range of soil types but prefer well-drained soils.
  • Ryegrass adapts to various soil types but thrives in fertile, well-drained soil.


Compacted soil: Compacted soil restricts root growth and water penetration, leading to weak, unhealthy grass.

What to look for: Signs of compacted soil include:
  • Water pooling on the surface
  • Hard, dry soil that's difficult to penetrate
  • Thin or bare patches of grass

How to fix it: Aerate your lawn annually, either in the spring or fall. This process creates small holes in the soil, allowing air, water, and nutrients to reach the grass roots more easily. You can call A Superior Cut to ask about our lawn aeration services.

Fertilizer -
Proper lawn fertilization is crucial for maintaining a healthy yard, especially during stressful periods like heat waves.
  • Use a slow-release fertilizer to provide steady nutrition.
  • Apply fertilizer in the early morning or evening to prevent burning.
  • During heatwaves, avoid over-fertilizing as this can stress the grass further.
  • Consider a soil test to determine exactly what nutrients your lawn needs.

Watering -
Proper watering is critical during a heatwave, but more isn't always better.
  • Water deeply and infrequently to encourage deep root growth.
  • Water early in the morning to minimize evaporation.
  • Adjust your watering schedule based on rainfall and temperature.
  • Use a rain gauge or moisture meter to ensure you're providing adequate water without overwatering.

Mowing -
Improper mowing practices can significantly stress your lawn, especially during hot weather.

Mowing too often: During a heatwave, grass growth often slows down. Mowing too frequently can weaken the grass and make it more susceptible to heat stress.

Dull blades: Dull mower blades tear the grass rather than cutting it cleanly, leaving ragged edges that are more prone to water loss and disease.

Best practices:
  • Mow when the grass needs it, not on a fixed schedule.
  • Keep your mower blades sharp.
  • During hot weather, raise your mowing height. Longer grass shades the soil, keeping it cooler and retaining more moisture.
  • Never remove more than 1/3 of the grass blade length in a single mowing.

Heat -
Sometimes, despite your best efforts, your lawn may still show signs of heat stress. Grass naturally slows its growth and may even go dormant during extreme heat to conserve energy.

What to look for:
  • Grass blades folding in half lengthwise
  • Footprints remaining visible long after walking on the lawn
  • Overall yellowing or browning of the lawn

Solutions:
  • Reduce foot traffic on stressed areas.
  • Avoid fertilizing during extreme heat.
  • Continue proper watering practices.
  • Be patient – most grasses will recover once temperatures cool down.

Specialized Care -
Different lawn types may require specialized care, especially during heatwaves.

Dwarf grasses:
  • These grasses often have shallow root systems and may require more frequent (but lighter) watering.
  • They typically require less frequent mowing, which can be beneficial during hot weather.

Non-grass features:
  • For lawns with rock gardens or xeriscaping elements, ensure these features aren't reflecting excessive heat onto nearby grass.
  • Consider using mulch around trees and in garden beds to help retain soil moisture.

Irrigation vs. sprinklers:
  • Drip irrigation systems can be more efficient than sprinklers, delivering water directly to the root zone of plants with less evaporation.
  • If you're using sprinklers, ensure they're properly adjusted to avoid wasting water on sidewalks or driveways.

Bonus tips for flowers and gardens:
  • Use mulch in garden beds to retain moisture and keep soil temperatures down.
  • Consider temporary shade cloth for sensitive plants during the hottest parts of the day.
  • Water container plants more frequently, as they dry out faster than in-ground plants.
  • Choose heat-tolerant plant varieties for summer plants.

Maintaining a healthy lawn during a heat wave can be challenging, but it's not impossible. By understanding the various factors that can affect your grass – from weeds and pests to soil conditions and mowing practices – you can take targeted action to help your lawn survive and even thrive.

Remember, a healthy lawn is more resilient to heat stress. Regular maintenance throughout the year, including proper mowing, watering, and lawn fertilization, will help your grass develop strong roots and better withstand periods of extreme heat.
