Removing grass for landscaping works three ways: cutting sod with a machine, smothering it with cardboard, or digging it out by hand — pick by lawn size and how soon you need to plant.
Standing over a stretch of lawn you want turned into a garden bed, the grass suddenly looks tougher than it did from the porch. It isn’t. The right method depends mainly on two things: how much ground you’re clearing and whether you’re planting right away or can wait a season. A good spade for removing grass handles small beds by hand; a rented machine clears a whole yard in an afternoon.
The Fastest Way: Renting or Buying a Sod Cutter
A sod cutter is the right tool when you have a large lawn to strip and want it done in hours instead of days. These machines slice under the turf and lift it in long strips you roll up and haul away. For small-to-medium lawns, either a powered walk-behind model or a manual kick-type cutter works; you rent the powered ones at equipment yards and most big-box home stores.
Preparation decides how clean the cut is. Clear rocks, sticks, toys, and debris first to protect the blade and avoid hazards. Mow the lawn short on the lowest setting a few days before. Then water lightly 1–3 days ahead so the soil is moist but not soaked — dry ground tears, soggy ground turns to mud and strains the machine. If you’re only removing part of the lawn, mark the area with stakes, chalk, or spray paint.
Set the cutting depth to about 1.5 to 3 inches per the Hamilton County SWCD sod cutter instructions; 1.5 to 2 inches handles most grasses, while deeper cuts work better when you need to fully detach the root system. Make straight passes with slight overlap, lift the blade before turning, and cut slabs into manageable pieces before hauling. Afterward, level the soil before planting or mulching.
No Machine? Smother the Grass With Cardboard or Newspaper
Smothering kills grass without digging or renting equipment, and it’s the lowest-effort route for garden beds, but it takes time — the grass needs weeks to die and break down.
Lay overlapping unwaxed cardboard (or several layers of newspaper) directly over the grass. Wet it thoroughly so it stays put and starts breaking down, then cover it with 3–4 inches of mulch or compost. The grass starves of light and dies underneath.
This works well when you’re not in a hurry to plant. If you need to put plants in right away, you can cut holes through the cardboard and plant directly — the technique works for no-till garden beds. Just confirm your planting plan works with whatever you’ve layered on top.
Hand Digging: The Labor-Intensive But Free Option
Hand digging suits small beds, paths, or spots where you can’t get a machine in. It costs nothing but time and effort, and it gives total control over depth.
Slice the turf into sections with a sharp spade or flat shovel, cutting a few inches deep to sever the roots, then pry each section up. Roll or fold the strips so the soil stays intact, and shake off excess dirt before composting the sod. The University of Maryland’s extension guidance on lawn and turfgrass removal methods covers all three approaches in detail.
Water lightly a day or two before digging so the roots slice cleanly; dry compacted soil makes the work brutal and tears the sod. For bigger hand-digging jobs, the right tool matters more than technique — the spade’s blade length and handle height determine how much leverage you get with each push.
| Method | Best For | Time & Effort |
|---|---|---|
| Sod cutter (rented) | Large lawns, quick removal | Hours; moderate effort |
| Cardboard smothering | New beds, no-till planting | Weeks to kill; very low effort |
| Hand digging | Small beds, tight spaces | Days; high effort |
Which Grass Removal Method Should You Choose?
Match the method to your timeline and the size of the job. Renting a powered sod cutter costs the most money but saves the most time — it’s the pick for a full lawn replacement or large garden expansion. Smothering costs almost nothing and saves your back, but you’ll wait a month or more before the grass is dead enough to plant through.
Hand digging sits in the middle: free, immediate, and the right scale for a 10-foot bed, but it will test your patience on anything larger. Whichever you choose, the common preparation steps — clear debris, mow short, water a couple days ahead — make every method work better. Follow the machine’s own instructions if you rent, keep the blade straight on manual cutters, and never turn a powered cutter with the blade still engaged.
FAQs
What’s the best depth to set a sod cutter?
Most sod cutters work best set between 1.5 and 3 inches deep. Shallow cuts around 1.5 to 2 inches handle typical lawn grasses, while deeper settings help when you need to fully detach stubborn root systems. Check your machine’s manual, since depth adjustment varies by model.
How long does cardboard smothering take to kill grass?
Cardboard smothering usually kills grass in four to six weeks during warm weather. The grass starves without light and breaks down beneath the cardboard and mulch. In cooler seasons it can take longer — plan ahead if you’re on a planting deadline.
Can I remove grass without renting a machine?
Yes. Hand digging with a sharp spade works well for small areas, and cardboard smothering handles larger beds with minimal effort over a few weeks. Both avoid rental costs but trade in labor or waiting time compared to a powered sod cutter.
