How To
Transplanting grass isn’t as tricky as it sounds—especially when you do it right. I’ve turned thin patches into thick, lush lawns in under 30 minutes by following a few key steps that minimize stress on the roots.
The secret lies in timing, sharp cuts, and keeping the soil moist while the grass settles in.
You’ll need a sharp spade, a can of water, and a little patience. Dig up small sections of grass, keeping as much root intact as possible, then replant them immediately in pre-moistened soil.
Water thoroughly right after transplanting, and you’ll see new growth within 10-14 days. The key is to avoid letting the roots dry out during the process.

What you need
- ● Sod cutter or spade – A sharp, sturdy sod cutter (rentable or ~$100) or a flat-edged spade for smaller patches. Pro tip: A sod knife (long, serrated blade) works great for precision cuts!
- ● New sod or grass plugs – Measure your bare spots and buy 10–20% extra to account for trimming. Choose high-quality sod (e.g., Kentucky Bluegrass, Bermuda, or Fescue) or grass plugs for patchy areas.
- ● Rake (bow or leaf rake) – A bendable steel rake (for leveling soil) or a plastic leaf rake (for debris removal).
- ● Garden hose with spray nozzle – A soaker hose or adjustable nozzle for deep watering.
- ● Lawn fertilizer – A slow-release, starter fertilizer (e.g., 20-20-20 or 10-10-10) to give your new grass a nutrient boost.
- ○ Soil amendment (optional but helpful) – Compost or topsoil (1–2 inches) to improve drainage and nutrients in poor soil.
- ● Knee pads or work gloves – Protect your hands and knees from dirt and sharp edges.
- ● String line & stakes – For marking straight edges if transplanting large areas.
- ● Weed barrier fabric – If your lawn has persistent weeds, lay down fabric before adding new sod.
- ● Lawn roller (lightweight) – Helps press sod into place for better root contact (rent or buy for ~$50).
- ● Post-transplant herbicide – A pre-emergent herbicide to prevent weeds from sprouting in the new sod.
Step-by-step instructions for transplanting grass to thicken your lawn
Here's how I transform thin patches into a dense, healthy lawn in under 30 minutes.
Prepare the Donor and Recipient Areas
First, identify the thickest section of your lawn for the donor plugs—this is where you'll take healthy grass pieces. Use a sharp knife or garden spade to cut 2-3 inch wide plugs, including the root layer. I aim for plugs that are about 1/2 inch deep to preserve root integrity. Water the donor area thoroughly the day before to soften the soil and make extraction easier.
Next, prepare the recipient area—the bare or thin spots you're filling. Loosen the soil with a rake, removing any debris or weeds. The goal is to create a soft, welcoming bed for your new plugs. If the soil is compacted, I use a garden fork to aerate 2-3 inches deep before proceeding. This ensures the transplanted grass roots can establish quickly.
Carefully Extract and Store the Grass Plugs
Lift the grass plugs from the donor area using a steady motion—don't pull or twist, as this can tear roots. I like to work in small batches, placing each plug on a damp towel to keep the roots moist while I prepare the recipient spots. If you're working in hot conditions, shade the plugs to prevent wilting. The key here is to handle the plugs gently; rough treatment stresses the grass and slows recovery.
For each plug, trim any excess soil or roots with clean shears, leaving about 1/4 inch of root attached. This keeps the plugs manageable and encourages faster root regrowth in their new home. If you're transplanting multiple plugs, label them if needed—though healthy grass looks identical, different varieties may behave slightly differently once moved.
Plant the Grass Plugs for Maximum Success
Dig small holes in the recipient area that match the size of your plugs. The depth should be just enough to bury the roots completely, with the grass surface level with the surrounding lawn. I press each plug firmly into the hole to ensure good soil contact—this reduces air pockets that can strangle new roots. Space the plugs about 3-4 inches apart to allow for natural spreading and filling in.
Water the newly planted plugs immediately after transplanting, soaking the soil until it's damp 2-3 inches deep. Avoid overwatering, though—you want the soil moist but not soggy. I like to use a gentle sprinkler or watering can to avoid dislodging the plugs. After watering, lightly rake the area to settle the soil and remove any air gaps around the edges of the plugs.
Maintain the Transplanted Grass for Strong Establishment
For the first 7-10 days, keep the transplanted area moist by watering lightly every 2-3 days. You'll know it's time to water again when the top 1/2 inch of soil feels dry to the touch. Avoid heavy foot traffic or mowing for at least 2 weeks—this gives the roots time to anchor without disturbance. If you notice any plugs wilting, give them an extra drink of water and check for signs of stress like yellowing.
Once the grass shows signs of regrowth—usually within 2-3 weeks—you can gradually return to normal lawn care. Mow the plugs when they reach about 3 inches tall, and fertilize lightly after 4-6 weeks to encourage strong root development. The transplanted grass will blend seamlessly with your existing lawn, and those thin spots will become just a memory.
Tips & tricks for transplanting grass
A few simple tricks will help you avoid common mistakes and get the best results from your grass transplanting project.
Timing Tip: The 30-minute window for completing the transplant is tight, so work efficiently but carefully. Prepare your tools and materials ahead of time—have your knife or spade, rake, garden fork, shears, and watering can all ready to go. This keeps the process moving smoothly without sacrificing quality. I like to set a timer for 25 minutes to stay on track while allowing flexibility for adjustments.
Donor Area Selection: Choose your donor area wisely—it should be the healthiest, thickest part of your lawn with no signs of disease or pest damage. Look for grass that's vibrant green and grows vigorously. Avoid areas with yellowing patches or thin spots, as these may not provide strong enough roots for successful transplantation. The plugs you take should be about 2-3 inches wide and 1/2 inch deep, so mark these dimensions with a ruler or measuring tape before cutting.
Root Care: Preserving those delicate roots is crucial for success. When extracting plugs, use a steady, upward motion rather than pulling or twisting, which can tear the roots. Keep the roots moist by placing plugs on a damp towel while you work, and avoid letting them dry out. If you're working in hot weather, shade the plugs to prevent wilting. Remember, gentle handling means faster recovery for your transplanted grass.
Soil Preparation: Don't skip the aeration step if your soil is compacted—those 2-3 inches of loosened soil make all the difference. Compacted soil can suffocate new roots, so use a garden fork to break it up before planting. For the recipient area, remove all debris and weeds to create a clean, welcoming space for your new grass. This simple step prevents competition for nutrients and water during the critical establishment period.

Frequently asked questions
Got questions about transplanting grass? You’re not alone! Here are some of the most common concerns—and their straightforward solutions.
When is the best time to transplant grass?
The ideal window is early spring or early fall when temperatures are mild (50–75°F). Avoid extreme heat or frost, as grass struggles to establish roots in harsh conditions. If you must transplant in summer, do it early morning or late evening to reduce stress on the sod.
How long does it take for transplanted grass to root?
Expect 1–2 weeks for initial rooting, but full establishment takes 4–6 weeks. Water deeply 2–3 times daily for the first week, then taper to 1–2 times daily. Avoid walking on it until you see new growth—usually after 3–4 weeks.
What if my transplanted grass turns brown or dies?
Brown patches often mean underwatering, overwatering, or poor soil contact. Check for:
- Dry edges → Water more frequently.
- Soggy soil → Improve drainage or reduce watering.
- Gaps under sod → Repress firmly or add a thin layer of soil.
Can I transplant grass in partial shade?
Yes, but choose shade-tolerant grass varieties like fine fescue or Kentucky bluegrass. Transplanting in partial shade is trickier because roots grow slower. Amend the soil with compost to improve fertility, and water 10–15% more than sunny areas to compensate for less sunlight.
Is it cheaper to transplant grass or reseed?
Transplanting (sod) costs $0.50–$1.50 per sq. ft. installed, while reseeding runs $0.10–$0.30 per sq. ft. but takes 6–12 months for full coverage. If you need a quick, lush lawn, sod wins. For budget-friendly, long-term projects, seeding is better—just prep the soil thoroughly!
Wrapping up and next steps
