Lawn by Season Frequently Asked Questions

General Lawn Care

General Lawn Care
How often should I water my lawn?

Most lawns need about 1 inch of water per week, including rainfall. Water deeply once or twice a week instead of frequent light watering to encourage strong root growth.

When should I fertilize my lawn?

Fertilize 2–4 times per year, depending on your grass type. Cool-season grasses do best in spring and fall, while warm-season grasses thrive with summer feedings.

What’s the best time of day to water my lawn?

Water early in the morning — ideally between 5 a.m. and 9 a.m. — to reduce evaporation and prevent disease caused by overnight moisture.

How can I tell if my lawn needs aeration?

If water pools on the surface or grass looks thin and patchy, your soil may be compacted. Aerate once a year, usually in spring or fall.

What’s the ideal mowing height for my grass?

Follow the “one-third rule”: never cut more than one-third of the grass blade at once. For most lawns, keep grass between 2.5–4 inches tall.

Spring Lawn Care

Spring Lawn Care
What should I do first in spring?

Start with light raking, remove debris, and test your soil. Overseed bare spots and apply a pre-emergent herbicide to prevent crabgrass.

When is the best time to seed my lawn?

Cool-season grasses: early spring or early fall.
Warm-season grasses: late spring when temperatures stay above 70°F.

Should I dethatch in spring?

Yes, but only if the thatch layer is thicker than ½ inch. Use a dethatching rake or power rake on dry, healthy grass.

Summer Lawn Care

Summer Lawn Care
How do I protect my lawn during heat waves?

Raise your mowing height to shade the soil, water deeply, and avoid fertilizing during extreme heat.

Why does my grass turn brown in summer?

It’s often dormancy, a natural survival response. Continue occasional deep watering, and it will recover when temperatures cool.

How can I reduce water usage during summer?

Use smart irrigation controllers and focus on deep watering. Consider drought-tolerant grass types like Bermuda or zoysia.

Fall Lawn Care

Fall Lawn Care
Why is fall the best time to fertilize?

Cooler weather helps roots grow deeper. Fertilizing in fall strengthens your lawn for winter and gives it a head start in spring.

Should I rake all fallen leaves?

Rake or mulch leaves regularly. Thick layers can block sunlight and trap moisture, leading to mold and dead patches.

Is overseeding necessary in fall?

Yes. Overseeding fills bare spots, thickens turf, and helps crowd out weeds before winter dormancy.

Can I aerate and fertilize at the same time?

Absolutely. Aeration opens pathways for fertilizer and water to reach the root zone more effectively.

Winter Lawn Care

Should I mow my lawn in winter?

Mow one last time before the first frost — slightly shorter than usual — to prevent matting under snow.

Can I fertilize my lawn in winter?

No. Grass growth slows or stops in cold weather, so fertilizer won’t be absorbed efficiently.

How do I prevent lawn damage during winter?

Limit foot traffic on frozen or snow-covered grass. Remove heavy snow piles to prevent smothering.

Grass and Soil Questions

How do I know my soil pH?

Test your soil every 2–3 years. Ideal lawn pH is 6.0–7.0. Add lime to raise pH or sulfur to lower it.

What’s the difference between cool-season and warm-season grass?

Cool-season grass thrives in northern climates and stays green in mild cold. Warm-season grass grows best in southern regions with long, hot summers.

How can I improve poor soil?

Topdress with compost, aerate annually, and fertilize based on soil test results to improve structure and nutrient content.

Weed and Pest Control

What’s the best way to prevent weeds?

Apply pre-emergent herbicide in early spring and fall, mow regularly, and keep your grass thick to crowd out weeds naturally.

How do I handle crabgrass?

Prevent with a pre-emergent in spring. If it appears later, spot-treat with a post-emergent herbicide designed for your grass type.

What are signs of lawn pests?

Brown patches, thinning turf, or birds digging for grubs are telltale signs. Use beneficial nematodes or insecticidal products if infestation is confirmed.

Lawn Equipment and Maintenance

How often should I sharpen mower blades?

At least twice per season, or every 20–25 hours of mowing.

What’s better — mulching or bagging grass clippings?

Mulching. It returns nutrients to the soil and reduces thatch when done properly.

How do I clean my lawn mower?

After each mow, remove grass buildup from the deck and blades. Clean with a hose and mild detergent to prevent corrosion.

Eco-Friendly and Sustainable Lawn Care

Can I compost my grass clippings and leaves?

Yes. Mix them with dry material like twigs or paper for balanced compost. Avoid composting chemically treated grass.

What’s a low-maintenance lawn alternative?

Try native grasses, clover lawns, or ground covers like creeping thyme — they need less mowing and water.

How can I make my lawn more eco-friendly?

Use organic fertilizers, compost regularly, install rain gardens, and reduce chemical treatments.
