The Best Time to Clear Land in Michigan: A Month-by-Month Calendar for Southeast Michigan
The Gibson Environmental Services crew
More than 10 years clearing land, cutting trails, and running forestry equipment in Southeast Michigan.
The best time to clear land in Michigan is whenever the ground will carry the machine and you can see what you are cutting, which in Southeast Michigan means late fall through the end of winter for most jobs: the leaves are down so the keeper trees and the invasive brush are easy to tell apart, the ground is firm or frozen so a tracked machine leaves no ruts in a wet woodlot, and the work is done before the spring growing season starts. Summer and early fall are the second window, once the ground dries, and spring is the one season we schedule around rather than into.
That is the short answer. The long answer depends on what you are clearing and what you want from the ground afterward, because a food plot, a fence row full of buckthorn, a lot headed for a foundation and a field gone to wild parsnip each have their own best month. This calendar lays all of it out for Oakland, Macomb, Wayne, Lapeer, Livingston, Genesee, Washtenaw and St. Clair counties: the ground by month, the job types by season, the invasive species by the month they are easiest to find and cut, and how we schedule our own land clearing year.
The Year at a Glance
| Month | The ground | Best clearing jobs | Species and timing notes |
|---|---|---|---|
| January | Frozen hard; snow cover varies | Wet woodlots, lakefront and creek banks, low ground that never dries; dead ash removal; woodlot thinning | Leaf-off: buckthorn, honeysuckle and the hairy poison ivy vines on trunks are easy to spot; bittersweet fruit still on the vine |
| February | Frozen; the firmest footing of the year | Same as January, plus fence rows and property line corridors; hunting trails and shooting lanes before spring | Everything dormant; the least sprouting of any cut; sap starting to move in maples late in the month |
| March | Thaw begins mid-month; frost coming out of the ground turns drives and fields soft | Finish frozen-ground jobs early in the month; dry, sandy and high ground after | Garlic mustard rosettes green up; last month to cut oaks before the wound-risk window |
| April | Mud season; wet ground stays soft, high ground dries by the end of the month | Lot clearing on well-drained sites; brush hogging on firm fields; marking and walk-throughs | Garlic mustard pulled before it flowers; buckthorn leafs out a week ahead of the woods and Callery pear blooms white, both easy to find; oak wounds best avoided from mid-April |
| May | Drying fast on most ground; low spots still wet | Pasture reclamation, field mowing, new home sites on dry ground | Garlic mustard flowering, cut before seed; honeysuckle leafs out early and shows itself; oak-risk window continues |
| June | Dry except after storms | Full season: lot clearing, mulching, brush hogging, fence rows | Wild parsnip and poison hemlock flowering: mow after the flower heads emerge and before seed; thistles the same; storm season starts |
| July | Dry; the firmest summer ground | Everything; food plot ground prepared for an August planting | Oak-risk window ends mid-month; knapweed and parsnip mowed before seed; the first sprouts on anything cut in winter get mowed |
| August | Dry, often hard | Food plots planted; pasture; late-summer cutting of tree of heaven, black locust and the sprouting species | Cutting the root-suckering trees now, as reserves move to the roots, gives the least sprouting; stump treatments on buckthorn and honeysuckle work from now into fall |
| September | Dry until the fall rains | Fence rows, trails and stand access before hunting season; lot clearing | Bittersweet fruit colors and the vines show; the second sprout-mowing pass on winter cuts |
| October | Firm early, softer after the rains; leaf-off begins late | Fall brush hogging; hunting lanes; woodlot work as the leaves come down | Buckthorn holds its leaves after everything else drops, the easiest month to find it; wild parsnip rosettes can be mowed low |
| November | Soft after rain, firming as it freezes | Leaf-off woodlot work; dead ash; storm cleanup | Full leaf-off; deer season shapes the schedule on hunting land, before it or after |
| December | Freezing up; frozen by the end of the month most years | Frozen-ground season begins: wet woodlots, lakefront, low ground | Dormant season; winter identification of vines and dead trees |
Two rules sit under the table. Frozen ground is the best ground: a tracked skid steer on frozen soil leaves no rut, crosses wet spots that are impassable in May, and does the least damage to the roots of the trees you keep. And leaf-off is when you can see: a woodlot in February is readable in a way the same woodlot in July never is.
Why Winter Is Our Best Season
Most of the land we clear in Southeast Michigan has a wet corner, a creek bottom, a low spot or a lakefront edge, and in the growing season that ground is either impassable or gets torn up. Frozen, it carries the machine. The invasive shrubs are dormant, so a cut now sprouts less in spring than a cut in June. Dead ash and the other standing dead trees stand out gray against the live ones. The keeper trees are easy to flag. And the job is done and the chip layer settled before the first growing season, which is when the ground starts turning back into pasture, lawn or plot. Our guide to fall and winter land clearing goes through what changes in the cold and what to get done before the snow.
The Spring Thaw: The Season We Schedule Around
From the first warm week in March until the high ground dries in late April, the frost comes out of the soil and everything turns soft: drives, field edges, woodlot floors. A heavy machine on thawing ground leaves ruts that last the year. So spring is for walk-throughs, marking, planning and the jobs on sandy, well-drained sites, and the mud-season weeks are when we would rather be scheduling your summer or next winter than running on your lawn. There is one spring job that is all about timing: pulling garlic mustard before it flowers in April, which is hand work on a woodlot floor, and the one invasive on this list a machine is the wrong tool for.
Summer and Early Fall: The Second Window
Once the ground dries, usually by late May on high ground and late June on the rest, the full season opens: lot clearing for a build, pasture reclamation, fence rows, mulching an overgrown parcel, brush hogging a field. The timing that matters most in summer is the mowing window for the biennial weeds: the extension weed scientists who tested it on wild parsnip found that a pass after the flower heads emerge and before the seed matures is the one that works, because a cut too early just produces a second stalk and a cut too late spreads ripe seed. Late June into July is that window for parsnip, poison hemlock and the thistles. August is the month for cutting the root-suckering trees, tree of heaven and black locust, when they sprout least, and for planting fall food plots. September and October are fence rows, trails, stand access and fall brush hogging ahead of the hunting season.
Best Month by Type of Job
| Job | Best months | Why | Guide |
|---|---|---|---|
| Overgrown lot or parcel, no build planned | November to March; June to September | Leaf-off and firm ground first; dry summer ground second | Land clearing |
| Lot for a new house | Whenever the build schedule needs it; frozen or dry ground preferred | The mulching pass opens the site; the pad is grubbed when the excavator is scheduled | Clearing a lot for a new house |
| Wet woodlot, creek bottom, lakefront | January and February | Only frozen ground carries the machine without damage | Lakefront clearing |
| Woodlot thinning, dead ash, weed trees | November to March | Leaf-off visibility; dormant cuts sprout least | Dead ash trees, weed trees |
| Fence row or property line | February; September to October | Firm ground along the line; done before the growing season or before hunting season | Overgrown fence lines |
| Pasture reclamation | May to June for the first pass; August for the sprout pass | Dry ground, then a second cut before the sprouts set seed | Pasture reclamation |
| Field mowing (brush hogging) | Late June to July; October | Weeds cut before seed; the fall pass sets up winter | Brush hogging |
| Food plot | Ground cleared May to July; planted in August | Chips settle and the seedbed is ready for a fall planting | Food plot clearing |
| Hunting trails, shooting lanes, stand access | February to March; September | Before spring growth, or just before the season | Hunting trail and shooting lane clearing |
| Invasive shrubs (buckthorn, honeysuckle, autumn olive) | Any leaf-off month to cut; August to October for stump treatment | Dormant cuts sprout least; fall is when the plant moves reserves to the root | Worst invasive plants |
| Storm cleanup | As soon as it is safe | Access first, then the hung-up and split trees, then the brush | Storm cleanup |
Species Timing: When Each Invasive Is Easiest to Find and Cut
| Plant | Easiest to find | Best time to cut or mow | Note |
|---|---|---|---|
| Common and glossy buckthorn | April (leafs out early) and late October (holds leaves late) | Any dormant month; stump treatment August to October | Sprouts from the stump; see buckthorn removal |
| Bush honeysuckle | April (first green in the woods) and fall (red berries) | Dormant season; stump treatment in fall | See bush honeysuckle removal |
| Autumn olive | May (silver leaves) and September (red fruit) | Dormant season or at flowering; expect resprouts | See autumn olive removal |
| Japanese barberry | Fall (red fruit holds into winter) | Dormant season | See Japanese barberry removal |
| Tree of heaven, black locust | Summer (leaves) and winter (seed clusters, pods) | Late summer, when reserves move to the roots | Root suckers; plan several summers of sprout mowing; see tree of heaven |
| Callery pear | April (white bloom) | Dormant season; stump treatment or grinding | Thorny thickets in fields |
| Garlic mustard | March to May | Pull in April before it flowers; cut in May before seed | Hand work; the one on this list a machine is the wrong tool for |
| Wild parsnip, poison hemlock | June to July (flowering) | Mow after the flower heads emerge, before seed; repeat | Sap and skin: full cover for anyone near it |
| Phragmites | September to November (plumes) | Late summer cutting with follow-up | See phragmites in Michigan |
| Oriental bittersweet and the vines | October (fruit) and winter (vines on trunks) | Cut at the base in any season, repeat | Poison ivy vines on trunks are hairy and visible in winter |
Oaks: The One Tree With a Calendar of Its Own
Oak wilt moves between trees on sap beetles that find fresh wounds, and the risk window in Michigan runs from mid-April to mid-July, with May and June the peak. A machine working among oaks can scuff bark, and a scuff in May is a wound. So on an oak-heavy lot we schedule the clearing for late summer through winter, keep the mulcher clear of the keeper oaks you flag, and treat any fresh wound in the window right away. Your oaks are the most valuable trees on the property; the calendar is how we keep them that way.
Hunting Land: Work Around the Seasons You Hunt
On hunting land the calendar bends around October and November. Shooting lanes, stand access and food plot ground get done in late winter or in late summer, so the woods are quiet by the time the season opens; the big woodlot work waits for the frozen ground after the season closes. Food plots go in in August for a fall planting. Our hunting land clearing page and the guide to food plot clearing cover the details, and the shooting lane clearing page covers the lanes themselves.
How We Schedule a Year
December through early March is frozen-ground season: the wet woodlots, the lakefronts, the dead ash and the thinning jobs. Mid-March through April we walk sites, mark keepers and plan, and run only on dry, sandy ground. May through September is the open season for everything else, with the mowing windows for the biennials in late June and the root-suckering trees in August. October and November are fence rows, fall brush hogging, hunting lanes and the start of leaf-off woodlot work. If your job has a window of its own, a build date, a planting date, a season opener, tell us on the walk-through and the schedule is built around it.
Common Questions
What is the best time of year to clear land in Michigan?
Late fall through the end of winter for most jobs: leaf-off makes the keepers and the invasives easy to tell apart, and frozen ground carries the machine without ruts. Summer and early fall, once the ground dries, are the second window. The spring thaw is the season to plan around.
Can you clear land in the winter?
Winter is our best season. Frozen ground carries a tracked machine across wet spots that are impassable in May, dormant brush sprouts less after a cut, and dead trees stand out against the live ones. Snow is rarely a problem; deep thaw-and-refreeze slush is.
Can you clear land when the ground is frozen?
Yes, and it is the only time to clear the wettest ground, creek bottoms and lakefront edges without tearing them up. A forestry mulcher grinds frozen stems and stumps as well as it does in July.
When is the worst time to clear land?
The spring thaw, from mid-March to late April on most ground, when the frost is coming out of the soil and a heavy machine leaves ruts that last the year. High, sandy ground is the exception.
When should I cut buckthorn in Michigan?
Any dormant month to cut it, with the stump treated from August through October when the plant is moving reserves to the root. Find it in April, when it leafs out a week ahead of the woods, or in late October, when it holds its leaves after everything else has dropped.
When can I cut oak trees in Michigan?
Late summer through winter is the safe season. From mid-April to mid-July fresh wounds on oaks draw the beetles that carry oak wilt, with May and June the peak, so clearing among oaks is scheduled outside that window and any wound inside it is treated right away.
When should a food plot be cleared and planted?
Clear and mulch the ground from May through July so the chips settle, then plant in August for a fall plot. A spring planting goes in as soon as the ground dries in April or May.
How long does it take to clear land?
A forestry mulcher moves through light brush and saplings at about an acre a day and slower through heavy saplings and small trees, so an overgrown lot is usually days and an overgrown parcel is weeks. Frozen or dry ground keeps the pace; thawing ground stops it.
