When to Start Mowing in Virginia: A Seasonal Guide

When to Start Mowing in Virginia: A Seasonal Guide

Every spring, homeowners across Draper, Dublin, and Radford make the same mistake — they either fire up the mower way too early or wait so long the grass gets out of control. Neither is good for your lawn. Timing your first mow of the season correctly sets the tone for how your yard looks all year long.

This guide breaks down exactly when to start mowing in Virginia, what to watch for before you cut, and how to build a lawn mowing schedule that keeps your yard looking sharp from spring through fall.

Why Timing Your First Mow Matters

Grass isn't just growing — it's recovering. After winter, your lawn is coming out of dormancy and the root system is still waking up. Cut it too early and you stress the plant before it has a chance to establish. Wait too long and you're hacking through thick, overgrown turf that clumps, clogs your mower, and leaves your lawn looking rough for weeks.

In the New River Valley, we deal with a mix of cool-season grasses — mostly tall fescue and Kentucky bluegrass — that behave differently than the warm-season grasses you'd find further south in Virginia. That matters when you're building your mowing schedule.

What Grass Type Do You Have?

Before you set a mowing date, know what you're working with.

Cool-Season Grasses (Most Common in the NRV)

• Tall Fescue — The workhorse of New River Valley lawns. Stays green longer into fall and greens up earlier in spring.
• Kentucky Bluegrass — Finer texture, spreads by rhizomes, common in older established lawns.
• Perennial Ryegrass — Often used in overseeding mixes.

Cool-season grasses do their best growing in the 60–75°F range. They slow down in summer heat and bounce back hard in fall.

Warm-Season Grasses (Less Common Here)

• Bermudagrass and Zoysia show up occasionally in the lower elevations of Pulaski County. These grasses go fully dormant and turn brown in winter. Don't mow them until they're actively growing and green — usually late May in our area.

When to Start Mowing in Virginia: The Short Answer

For most lawns in Draper, Dublin, Radford, and Pulaski — mid-March to early April is when you should be watching your grass closely. Here's the rule of thumb:

Start mowing when your grass reaches 3.5 to 4 inches tall and soil temperatures are consistently above 50°F.

You can check soil temperature at greencast.com or pick up a simple soil thermometer at any farm supply store for around $10–$15. Don't guess — the ground in the NRV can stay cold longer than you'd expect, especially after a wet winter.

Month-by-Month Lawn Mowing Schedule for Virginia

January – February: Keep the Mower in the Garage

Nothing to cut. Cool-season grasses are dormant or barely active. Use this time to sharpen your mower blades, change the oil, and check the air filter. A dull blade tears grass instead of cutting it cleanly — that leads to brown tips and disease pressure.

March: Watch and Wait

Early March is too soon for most NRV lawns. But by mid-to-late March, you might see your fescue starting to push new growth. Check the height. If it's hitting 3.5–4 inches, go ahead and mow — but keep your blade height high. Set it to cut at 3 inches, no lower.

One of the biggest mistakes we see is homeowners scalping their lawn on the first mow of the year. Don't do it. Never remove more than one-third of the blade height in a single pass — that's the "one-third rule" and it applies all season long.

April: Ramp Up the Schedule

April is prime growing season for cool-season grasses in Virginia. Expect to mow every 7–10 days depending on rainfall and temperatures. If April is wet — and in the New River Valley, it often is — you might be mowing every week.

This is also the time to think about spring cleanup if you haven't already. Debris, leaves, and thatch left over from winter can smother new growth and create conditions for fungal disease.

May: Peak Growth, Stay Consistent

May brings fast growth and the need for a consistent lawn mowing schedule. Keep cutting at 3–3.5 inches. If you let it go too long between cuts and the grass gets tall, raise your blade height and take it down gradually over two or three mows — don't scalp it in one shot.

May is also a good time to evaluate your trimming and edging situation. Clean edges along driveways, sidewalks, and beds make a huge difference in how professional a lawn looks.

June – August: Summer Slowdown

Cool-season grasses slow down significantly in summer heat. You may go from mowing weekly to every 10–14 days. Raise your blade height to 3.5–4 inches during summer. Taller grass shades the soil, retains moisture, and handles heat stress better.

Avoid mowing during the hottest part of the day. Early morning or evening is better for the grass and for you.

If your lawn goes semi-dormant and growth nearly stops, don't force it. Mowing stressed, slow-growing grass does more harm than good.

September – October: Fall Rebound

This is the second peak growing season for cool-season grasses. Cooler temps and fall rains kick growth back into gear. Get back on a weekly or every-10-day schedule. Fall is also the best time to overseed thin or bare spots — and consistent mowing helps new seedlings establish without getting shaded out.

Don't skip your fall cleanup. Leaves left on the lawn through November can mat down and kill the grass underneath.

November – December: Wind It Down

Keep mowing until growth stops — usually after the first hard frost. Your last mow of the season should leave the grass at about 2.5–3 inches. Too long going into winter and you risk snow mold. Too short and the roots are exposed to freeze-thaw damage.

Common Mowing Mistakes to Avoid

Mowing too short (scalping) — The number one mistake. Scalping stresses the grass, exposes soil, and invites weeds. Keep it at 3 inches minimum.

Mowing with dull blades — Dull blades shred the grass tip instead of cutting it. You'll see a brown haze over the lawn a day or two after mowing. Sharpen blades at least twice a season.

Mowing wet grass — Wet clippings clump, clog your mower deck, and spread fungal disease. Wait until the lawn dries out.

Ignoring clippings — Grass clippings are free fertilizer. If you're mowing on schedule and not letting the grass get too long, leave the clippings on the lawn. They break down fast and return nitrogen to the soil.

Mowing in the same direction every time — Alternate your mowing pattern. Grass leans in the direction it's cut. Changing direction keeps it upright and prevents ruts.

What About Mulching?

If you're not already mulching your lawn beds, spring is the time to do it. A 2–3 inch layer of hardwood mulch around trees, shrubs, and beds retains moisture, suppresses weeds, and gives your property a clean, finished look. Just don't pile it against tree trunks — that causes rot.

We handle mulching services throughout the New River Valley if you'd rather have it done right without the weekend project.

Should You Hire a Pro or DIY?

Honestly? It depends on your situation. If you've got a small, flat yard and enjoy the work, DIY mowing is totally manageable if you follow the schedule above. But if your property is large, has slopes, or you just don't have the time to stay consistent — inconsistent mowing is worse than hiring it out.

The Bottom Line

In Virginia's New River Valley, your mowing season runs roughly from mid-March through November. Cool-season grasses like tall fescue need consistent cuts at the right height — not too short, not too infrequent. Follow the one-third rule, keep your blades sharp, and adjust your schedule with the seasons.

Get the timing right and your lawn will reward you all year. Get it wrong and you'll spend the whole summer playing catch-up.
