A lush, green lawn boosts curb appeal and makes your home more inviting. But keeping it that way takes more than just watering—it all starts with the right mowing schedule. Mow too often, and the grass weakens. Mow too little, and weeds take over. So, how often should you mow? The answer depends on your grass type and the season.
Let’s break down the best mowing schedule for different grass types and seasons. This guide will give you essential tips for a healthy, thriving lawn year-round.

Why Regular Mowing Matters
Mowing does more than keep your lawn looking neat. It helps grass grow stronger by removing the top layer, encouraging fresh, dense growth. A steady mowing routine shades the soil, locks in moisture, and prevents weeds from taking over.
Letting grass grow too tall weakens it, making lower blades struggle for sunlight. On the other hand, cutting too short stresses the roots, dries out the soil, and creates weak spots. The right mowing balance keeps your lawn green, thick, and strong against weeds, pests, and disease.
How Often Should You Mow?
Grass grows at different speeds depending on the type, season, and weather. A well-timed mowing schedule keeps your lawn healthy and reduces stress.
Cool-Season Grasses (Fescue, Bluegrass, Ryegrass)
These grasses thrive in spring and fall when temperatures are mild. Growth slows down in extreme heat.
- Mow every 5–7 days in spring and fall when growth is fastest.
- Mow every 10–14 days in summer to avoid heat stress.
- Keep grass 3–4 inches tall to protect roots and create a dense, weed-resistant lawn.
Skipping mowing during peak growth causes weak, floppy blades that bend over, making it harder to cut evenly. Keeping the right height allows the lawn to absorb sunlight while maintaining strong roots.
Warm-Season Grasses (Bermuda, Zoysia, St. Augustine, Bahia)
These grasses grow best in late spring and summer when temperatures are high. They slow down in cooler months, requiring less mowing in fall and early spring.
- Mow every 7–10 days from late spring to early fall to keep a clean look.
- Mow every 5–7 days during peak summer growth.
- Keep grass 2–3 inches tall for stronger roots and better drought resistance.
Cutting too short in summer exposes the soil to heat, leading to moisture loss and dry patches. Letting it grow too tall, however, creates a thin, weak lawn that is more likely to attract pests and weeds.
Mixed Grass Lawns
Some lawns contain a mix of cool- and warm-season grasses, requiring a flexible mowing schedule.
- Mow every 5–7 days in spring and fall when cool-season grasses grow faster.
- Mow every 7–10 days in summer when warm-season varieties take over.
- Adjust the mowing height slightly higher to balance different growth rates.
Since mixed lawns grow unevenly, maintaining a steady schedule prevents patchy areas while reducing stress on weaker grass types.
The One-Third Rule for Mowing
Never cut more than one-third of the grass blade in a single mowing session to keep them strong and healthy. Cutting too much at once weakens the plant, exposes the soil to heat, and invites weeds.
Why This Rule Matters
Mowing removes the top portion of the blade, which contains stored nutrients. Grass uses these nutrients to recover after being cut. Removing too much at once makes the lawn struggle to regenerate and leads to the following:
- Grass Shock: Weakens the lawn and slows regrowth.
- Dry, Brown Spots: Exposes too much of the blade, causing moisture loss.
- Thinning Grass: Weak grass struggles to recover, making the lawn look uneven.
- Increased Weed Growth: Bare spots left by scalping create the perfect environment for weeds.
How to Apply the One-Third Rule
- Measure Grass Height: Check growth before mowing to avoid excessive cutting.
- Mow in Stages if Necessary: If the grass is too tall, mow in increments over several days instead of all at once.
- Adjust Mowing Frequency: Mow consistently to avoid overgrowth between cuts.
Seasonal Lawn Mowing Guide
Grass grows differently in each season. Adjust mowing habits to match weather conditions.
Spring
Mow weekly once the grass reaches at least 3 inches. You only need to remove a small amount per cut to allow steady growth.
Summer
You can increase mowing height to prevent grass from drying out. We recommend you mow every 7–10 days during extreme heat to reduce stress.
Fall
Continue mowing weekly until growth slows during fall. Our best tip is to lower mowing height slightly before winter to prevent disease.
Winter
Mow only if needed during winter. Grass may go dormant, requiring little to no cutting.
Lawn Mowing Best Practices
Small adjustments to your mowing routine can make a big difference in the long-term health of your grass. Follow these best practices to get the most out of every mow:
Keep Your Mower Blades Sharp
Dull mower blades tear grass instead of cutting it cleanly. This creates ragged edges that turn brown and invite disease. If your lawn looks uneven or the grass tips appear shredded, it’s time to sharpen the blades.
- What to do: Sharpen your mower blades at least twice per season or whenever the grass looks torn after mowing.
- Why it matters: Clean cuts heal faster, allowing grass to recover quickly and stay green.
Change Your Mowing Direction Regularly
Mowing in the same direction every time causes grass to lean one way, creating uneven growth patterns. Repeating the same pattern also compacts the soil, making it harder for roots to grow deep.
- What to do: Switch up your mowing direction each time you mow—alternate between horizontal, vertical, and diagonal patterns.
- Why it matters: It keeps the grass upright, reduces compaction, and helps the lawn grow evenly.
Leave Grass Clippings on the Lawn
Bagging clippings after every mow removes nutrients that could benefit your lawn. Instead of throwing them away, let them break down naturally. Grass clippings decompose quickly and act as a free fertilizer that returns essential nutrients to the soil.
- What to do: Use a mulching mower or leave small clippings on the lawn after cutting. If clippings are too long, spread them out with a rake.
- Why it matters: This improves moisture retention, adds nutrients, and reduces the need for extra fertilizers.
Mow When the Grass is Dry
Wet grass clumps together, making it harder to cut evenly. These clumps block sunlight from reaching lower blades and can create bare patches over time. Wet grass can also clog the mower deck, making mowing more difficult.
- What to do: Mow in dry conditions, preferably after the morning dew has evaporated or before evening moisture sets in.
- Why it matters: Dry grass cuts more evenly, reducing mower strain and promoting uniform growth.
Avoid Mowing in Extreme Heat
Mowing in hot weather puts unnecessary stress on your lawn. Grass loses moisture faster when cut in high temperatures, leading to weak, dry patches.
- What to do: Mow in the early morning or late evening during summer to minimize heat stress.
- Why it matters: This helps the lawn retain moisture, reduces heat-related stress, and keeps the grass looking fresh.
