So, you think there’s no best time to mow your lawn as long as the grass gets cut? Professional landscapers say quite the opposite! According to the experts, timing your mowing can mean the difference between a lush, healthy lawn and one that's prone to diseases and struggling to thrive.
Understanding When Is the Best Time to Mow Your Lawn
Picking the best time to mow the lawn isn't just about convenience - it's about grass health. According to the research on healthy lawn mowing practices from the University of Minnesota, proper mowing timing can reduce the risk of diseases by 40% while promoting deeper root systems and better drought tolerance. The key factors to consider include moisture levels, temperature, and recovery time before evening dew sets in.
When is The Best Time of Year To Mow Your Lawn?
Spring is the best time of year to mow your lawn. The spring months between March and June are the months when the grass grows longest and quickest. However, you can also mow during the summer and during the fall.
1. Spring: Best Time of Year to Mow Your Lawn
Start mowing your lawn in Spring when the grass reaches 3-4 inches, typically in mid-March. Cool-season grasses resume growth when the soil temperature reaches 50-60°F.
- When to mow: Early morning (after 9 AM) and late afternoon before 6 PM,
- What to avoid: Mowing frozen grass or wet soil, cutting more than one-third blade length
2. Summer: Mow In the Morning Hours
Warm-season grasses thrive at 75-90°F, while cool-season varieties go semi-dormant during the extreme heat of summer.
- When to mow: 8-10 AM after dew evaporates, 4-6 PM when cooler
- What to avoid: Mowing mid-day(10 AM-2 PM) and in the evening after 6 PM
3. Fall: For Certain Cool-Season Grasses
During fall, cool-season grasses like Kentucky bluegrass, fine fescue, and tall fescue resume growth when temperatures drop below 80°F.
- When to mow: In the mid-morning
- What to avoid: Cutting the grass too short, mowing over leaves
4. Winter: Equipment Maintenance Season
In most regions, you don’t need to mow in the winter. Cut the grass occasionally only if the temperature gets above 40°F.
When To Mow Your Lawn During the Year
| Season | Grass Growth / Conditions | Best Mowing Times | What to Avoid |
| Spring | Cool-season grasses resume growth at 50–60°F. Start mowing when grass reaches 3–4 inches (mid-March). | Early morning (after 9 AM) or late afternoon (before 6 PM). | - Mowing frozen or wet soil- Cutting more than ⅓ of the blade length |
| Summer | Warm-season grasses thrive at 75–90°F. Cool-season grasses may go semi-dormant in extreme heat. | 8–10 AM (after dew dries) or 4–6 PM (cooler part of the day). | - Mowing midday (10 AM–2 PM)- Mowing after 6 PM |
| Fall | Cool-season grasses (e.g., Kentucky bluegrass, fine/tall fescue) grow again when temperatures drop below 80°F. | Mid-morning. | - Cutting grass too short- Mowing over leaves |
| Winter | Grass growth slows or stops; mowing is rarely needed. | Only mow if temps rise above 40°F. | - Regular mowing (focus on equipment maintenance instead). |
What is The Best Time of The Week to Mow Your Lawn?
- Optimal days to mow your lawn: Tuesday - Thursday (follows the 5 - 7 day growth cycles)
- Weekend alternatives: Saturday after 9 AM, Sunday afternoon
- Days to avoid: Monday (grass might be overgrown), Friday (might conflict with weekend watering)
What is the Best Time of Day to Mow Your Lawn?
Mid-Morning (8-10 AM)
University research shows that grass cut during the optimal morning hours recovers 25% faster. Here's why cutting grass in the mid-morning hours works:
- The dew has evaporated
- Temperatures are manageable
- Grass gets a full day for recovery
- Avoids the stress of peak heat
Late Afternoon (4-6 PM)
Late afternoon is another ideal time to mow your lawn. Cutting grass in the late afternoon hours works because:
- Peak heat has passed,
- The grass is dry
- Your lawn gets 2-3 hours to recover before dew
Times to avoid mowing your lawn
- Early morning (before 8 AM): Wet grass tears, promotes disease, creates clumping
- Midday (10 AM-2 PM): Burns grass tips, heat stress, dangerous conditions
- Evening (after 6 PM): No recovery time, disease susceptibility, noise issues
When is The Best Time of Day to Mow Your Lawn?
| Time of Day | Why It’s Good (or Bad) | Research / Notes |
| Mid-Morning (8–10 AM) |
✔ Dew has evaporated ✔ Temperatures are manageable ✔ Grass gets a full day to recover ✔ Avoids peak heat stress |
University research shows that grass cut at this time recovers 25% faster |
| Late Afternoon (4–6 PM) |
✔ Peak heat has passed ✔ Grass is dry ✔ 2–3 hours of recovery before dew forms |
A safe second-best mowing window |
| Early Morning (Before 8 AM) | ✘ Grass is still wet → tearing & clumping ✘ Higher risk of fungal disease | Not recommended |
| Midday (10 AM–2 PM) |
✘ High temps burn grass tips ✘ Causes heat stress ✘ Uncomfortable/unsafe for the mower |
Worst time to mow |
| Evening (After 6 PM) |
✘ Limited recovery before dew ✘ Higher disease risk ✘ Noise disturbance |
Avoid if possible |
