Almost every cedar job starts with the same question. Do you grind it where it stands, or push it out with a dozer? Both clear the land. They leave you with very different property afterwards, and the right answer depends on what you intend to do with the ground once the cedar is gone.
Here is how we decide, and what each method actually does to Hill Country ground.
What Each Machine Actually Does
A forestry mulcher is a drum of carbide teeth on the front of a skid steer or a tracked carrier. It takes the tree down where it stands and grinds it, trunk and limbs, into chip. Nothing gets stacked and nothing leaves the property. The stump stays in the ground, usually cut flush or a few inches proud.
A dozer works from the root. The blade pushes the tree over and lifts the root ball out of the ground, then the material gets windrowed into piles. What you are left with is bare, disturbed soil and a row of piles that have to be dealt with.
That is the real difference. A mulcher removes the canopy and leaves the ground intact. A dozer removes the tree and disturbs the ground doing it.
The Regrowth Question, Answered Properly
People assume that leaving the stump means the cedar grows back. For Ashe juniper, the cedar most of this country is covered in, that is not how it works. Ashe juniper does not sprout from a cut stump. Once the top is off, that tree is finished. You do not need to pull the root to kill it.
Redberry juniper is the exception. It does resprout from the base after the top is removed, and it turns up more as you move west. If you are west of Lampasas and unsure which you have, it is worth identifying before choosing a method, because redberry needs follow-up treatment that Ashe juniper does not.
What does come back on both is seedlings. A mature cedar has been dropping seed on that ground for years, and clearing the canopy gives every one of those seeds light and moisture it did not have before. The regrowth you see two or three years after a clearing job is almost never the old stumps. It is a new generation coming up out of the seed bank.
That is true whether you mulch or doze. Clearing cedar is not a one-time event on any method. Plan on walking the property and knocking back seedlings while they are small, because a cedar you can cut with loppers at year two is a machine job at year ten.
When Mulching Is the Right Call
Mulching suits the job when you want the cedar gone but the ground left alone.
- Light to moderate cedar cover, where the machine can keep moving
- Slopes and thin soil, where a dozer would take the topsoil with the tree
- Selective clearing, where you want the live oaks and the good hardwoods left standing
- Recreational and wildlife property, where opening the understory matters more than bare ground
- Anywhere you do not want piles, burning, or haul-off to deal with afterwards
The chip left behind is a real benefit on erodible ground. It holds soil in place through the first heavy rains and breaks down over a couple of seasons. The thing to watch is depth. A thin mat is good cover. A deep one smothers the grass you were trying to release, and on a heavy cedar stand that is easy to end up with. If the goal is pasture, tell your operator so, because it changes how the material gets spread.
When a Dozer Is the Right Call
A dozer earns its place when you need the ground itself, not just the view.
- Heavy, closed-canopy cedar where a mulcher would be grinding all week
- Anything being built on. A building pad or a road needs the roots out and a clean subgrade
- Fence lines, where you want a clean strip and no stumps in the way of posts
- Conversion to improved pasture, where stumps would fight a shredder for years
- Reshaping ground. If the land is getting graded anyway, the cedar comes out as part of that work
The cost of a dozer is in what it leaves you. Piles have to go somewhere. That means a grinder, a burn, or haul-off, and all three add to the job. Burning is the cheapest of the three and the least predictable, because county burn bans come and go with the weather. Check your county’s current status before you plan a job around burning anything.
The Soil Cost Nobody Mentions
Much of this country has four to eight inches of soil sitting on limestone. When a dozer lifts a root ball out of ground like that, soil comes with it and ends up in the pile. On flat, deeper ground that is a fair trade. On a thin slope it is not, because that soil took a very long time to get there and you are not replacing it.
This is the main reason we will talk an owner out of dozing a hillside they wanted dozed. If the ground is thin and steep, mulch it.
About Cedar and Your Water
You will hear that clearing cedar brings back springs, and that every tree is drinking some large number of gallons a day. It is the most common reason people give us for wanting cedar off their place.
The research is a good deal less certain than the folklore. A study at Camp Bullis measured recharge into caves before and after juniper removal and found no measurable increase in recharge afterwards. What did change was surface runoff, which rose from roughly three percent of the water budget to as much as ten percent. More water moving across the surface is not the same thing as more water going into the ground, and on shallow, fractured Hill Country ground the relationship between the two is complicated.
That does not make cedar clearing pointless. It makes the water argument the weakest reason to do it. Clear cedar because you want grazeable grass, usable acreage, access through your property, better wildlife habitat, or less fuel standing next to your house. Those benefits are real and immediate. If the springs come back, treat it as a bonus rather than the plan.
What Drives the Cost
Clearing is quoted by the acre, and the spread between a cheap acre and an expensive one is wide. What moves it:
- Density. Scattered cedar in open pasture is quick. Closed canopy you cannot walk through is slow on any machine.
- Stem size. A field of six-inch cedar mulches fast. Old-growth trunks take real time per tree.
- Terrain. Slope, rock outcrop and gullies all slow a machine down and limit which one can work the ground.
- Selectivity. Take everything and the machine never stops. Save every oak and the operator is working around trees all day.
- Debris handling. Mulching has none. Dozing has piles, and what happens to them is a separate line on the quote.
- Access. If equipment cannot get to the back of the property, building the access is part of the job.
Per acre, mulching usually wins on light to moderate cover and a dozer usually wins on heavy cover, because production rate flips as density goes up. Anyone quoting you a per-acre number without walking the ground is guessing.
Most Jobs Use Both
On a typical place we will doze where the building pad, the road and the fence lines are going, because those need clean subgrade and no stumps. Then we mulch the rest, because the pasture and the slopes are better off with their soil and their cover left where it is.
Deciding method by method across a property costs less than committing the whole job to one machine, and leaves you with land that suits what you actually plan to do on each part of it.
FAQ
Will cedar grow back from the stumps if I mulch?
Not with Ashe juniper, which does not resprout from a cut stump. Redberry juniper does, and it shows up more toward the west. What comes back on either is seedlings from the existing seed bank, so expect follow-up regardless of method.
Can I build on mulched ground?
Not directly. The stumps and roots are still in there, and chip is organic material that will keep breaking down and settling. Anything carrying a load needs that stripped and a compacted subgrade underneath.
How long does the mulch take to break down?
Usually a couple of seasons for a normal mat, longer where it was laid deep or where the ground stays dry. Grass comes through a thin layer without much trouble.
What is the best time of year to clear cedar?
Late fall through winter is easiest. The ground is firm, the heat is not fighting the machines, and you are clear of nesting season. Wet spring ground rules out heavy equipment on clay entirely.
Do I need a permit?
Clearing on private rural acreage usually does not require one, but it depends on your county, your groundwater district, whether you are inside a city’s extraterritorial jurisdiction, and whether the work touches a creek or floodplain. Burning the debris is governed separately by the county burn ban. Worth one phone call before you start.
Clearing Cedar in Central Texas
We run dozers, excavators and both skid steer and tracked mulchers out of Johnson City, across thirteen Central Texas counties. On most places the answer is not one machine or the other, it is knowing which part of the property wants which.
Have a look at our land clearing services, or at what clearing looks like in Johnson City, Dripping Springs and Wimberley. If you are clearing ahead of building, the next thing to get right is how the road drains.
