Serving Crete's Established Community

Crete features beautiful tree-lined streets and historic neighborhoods where homeowners take pride in their yards. However, these lawns face serious fungal challenges when hot and humid weather arrives. Our program provides five monthly applications from May through September to protect your turf when it is most vulnerable. Crete’s location means weather patterns frequently trigger our 140 Rule. When heat and humidity combined exceed 140, fungus becomes nearly inevitable without professional help. This program is specifically designed to guard your yard against brown patch and powdery mildew, ensuring your lawn stays healthy during the peak summer months when environmental conditions are ideal for fungal outbreaks and permanent turf damage that can ruin your curb appeal. Common lawn diseases we treat:

Crete Lawn Care Recommendations

Proper habits significantly impact disease pressure in Crete lawns alongside our professional services. The most critical rule is to water only in the early morning between 4 AM and 8 AM and never at night. Tree-lined neighborhoods already have heavy morning dew; adding evening water extends leaf wetness to 12 hours, creating perfect conditions for spores. This single habit is likely the most important disease prevention measure you can take. You should also maintain a mowing height of 3.5 to 4 inches, especially in partially shaded areas. Taller grass develops deeper roots and stronger plants that can resist disease stress better. Finally, balanced nutrition through proper fertilization creates healthy grass that is less likely to get infected.

The Preventative Philosophy

Our approach to lawn disease management is fundamentally preventative because reacting after the fact simply does not work. Waiting until you see fungus fails for several reasons. First, visible fungus means the grass is already permanently dead in those spots; you are treating damage that has already been done. Second, the weather conditions that caused the outbreak will persist all summer, causing the disease to return almost immediately after a reactive spray. Third, these diseases spread incredibly fast, turning a small patch into a large dead area in just 3 to 5 days. Our preventative approach stops the damage before it starts, using systemic medicine that protects your grass from the inside out all season long.

Complete Coverage Through Professional Application

Lawn Fairy Ring Fungus Treatment | Yard Boss

All of our treatments are applied as liquid sprays using professional equipment for uniform and precise coverage. Liquid products perform much better than granules because they are absorbed faster and provide better blade coverage for curative action. After each application, you must water your yard within 24 hours to move the medicine to the root zone where it can be absorbed. We rotate between two different chemical formulas to prevent resistance, which develops faster with fungicides than with any other lawn product. This rotation is essential for long-term effectiveness. Monthly applications are necessary because as your grass grows and you mow each week, you slowly remove the tissue that contains the protective medicine.

Our Frequently Asked Questions

At Yard Boss, we understand that you may have questions about our services, processes, and how we can help you achieve the perfect lawn.  Whether you’re curious about our lawn care techniques, service areas, or the benefits of professional lawn maintenance, you’ll find the information you need right here. If you have any additional questions, feel free to reach out to our friendly team!

Yes. Like all products we use, once the application is dry, it is safe for everyone—pets, children, and adults. Drying typically takes about 1 hour but may take longer on cool, cloudy days.

Safety protocol: Keep people and pets off the lawn until dry (usually 1 hour). After that, normal use can resume.

It depends on your lawn's history and grass type:

 YES, you should do the program if:

  • Your lawn has a history of fungus or disease (even if currently clear)
  • You have primarily Kentucky Bluegrass (highly susceptible to fungus)
  • Your lawn experiences regular brown/dead patches in summer
  • You've had disease problems in previous years
  • You want preventative protection (cheaper than reseeding dead areas)

NO, you probably don't need the program if:

  • Your lawn has NO history of fungus or disease
  • You have primarily Turf Type Tall Fescue (more disease resistant)
  • Your lawn stays healthy all summer without treatment

HOWEVER: If you notice unusual brown, yellow, or dead spots during summer, contact us immediately so we can diagnose the issue. Early detection is critical.

No. This is why:

  • Environmental amplification: Fungus and disease are driven by heat, humidity, and wet conditions. Even if we kill the fungus, weather conditions will cause reinfection within days.
  • Overnight lows above 65°F: When nights stay warm, disease pressure is continuous—one application won't provide lasting control
  • Preventative component needs time: The systemic fungicide needs to be in the plant before disease strikes
  • Damage is permanent: By the time you see fungus, grass is already dead. Prevention is the only effective approach.

Bottom line: Reactive single treatments don't work for lawn fungus. The full preventative program is necessary for control.

It depends on your grass type:

  • Kentucky Bluegrass lawns: Yes, it is highly likely you will need fungicide treatments every year. Kentucky Bluegrass is extremely susceptible to summer fungus diseases, especially brown patch.
  • Turf Type Tall Fescue lawns: This is case-by-case. Tall fescue is more disease-resistant than bluegrass. Some fescue lawns need treatment; others don't. We'll assess your specific situation.

Long-term solution: Overseeding with newer, disease-resistant grass cultivars can reduce (but not eliminate) the need for fungicide over time.

We use professional-grade fungicides that combine both curative and preventative active ingredients. We rotate between two different chemical mixes (Mix #1 and Mix #2) to prevent resistance development.

This is an all-liquid product that we spray onto the lawn. Liquid products:

  • Act much faster than granular
  • Can be taken up by the plant much faster
  • Provide better coverage and adhesion to grass blades
  • Allow us to combine curative + preventative in one application
  • Offer more precise dosing

This is why we exclusively use liquid fungicides—they're simply more effective

Great question. There are several reasons:

  • Product cost: Fungicides are significantly more expensive than fertilizer and weed control products. Professional-grade fungicides cost 2× more per application than standard fertilizer.
  • Multiple active ingredients: We must mix multiple products together to control different fungus types and provide both curative and preventative action.
  • Resistance management: We need two complete sets of products (Mix #1 and Mix #2) to rotate chemistry and prevent resistance—essentially double the product inventory.
  • Specialized application: Liquid fungicide application requires specific equipment, calibration, and expertise.
  • Higher application rate: Fungicides are applied at higher volumes than fertilizer for proper coverage.

Value perspective: While more expensive than fertilizer, fungicide is cheaper than reseeding large dead areas from disease damage. Dead grass from fungus won't recover—it must be reseeded. Prevention costs less than repair.
