Moving a tree is a big task, but with the right know-how, you can succeed. This step-by-step expert guide on how to transplant a tree without killing it will give you the confidence to do it right.
Timing is everything when you move a tree. The best time is during its dormant season, when it’s not actively growing. For most trees, this means late fall after leaves drop or early spring before buds break. This gives the roots time to establish before summer heat or winter cold stress the tree.
You’ll need to gather your tools before you start. Having everything ready makes the process smoother and faster for the tree. Here’s a basic list:
* A sharp, clean spade and/or a round-point shovel
* A tarp or burlap for moving the root ball
* Burlap and twine for wrapping the root ball
* A wheelbarrow or cart (for smaller trees)
* Pruning shears or a saw
* A garden hose and water source
* Organic compost and mulch
* A measuring tape
How to Transplant a Tree Without Killing It
The key to success is preserving as much of the root system as possible. A tree’s roots are its lifeline, and damaging to many of them causes severe shock. The following steps are designed to minimize that shock and give your tree its best chance.
Step 1: Choose the New Location Carefully
Don’t just dig a hole anywhere. The new site must meet the tree’s needs for sunlight, soil, and space. Check the mature size of the tree to ensure it won’t interfere with buildings, power lines, or other plants. Test the soil drainage by digging a test hole and filling it with water; if it drains within a few hours, the spot is good.
Step 2: Prepare the New Hole First
This is a critical tip: dig the new hole before you dig up the tree. You want to minimize the time the roots are exposed to air. The new hole should be two to three times wider than the expected root ball, but only as deep as the root ball’s height. Planting too deep is a common mistake that can suffocate roots.
Loosen the soil around the edges of the hole so roots can expand easily. You can mix some compost with the native soil you removed, but avoid creating a soft, rich pocket that the roots won’t want to leave.
Step 3: Prune the Tree (If Needed)
For larger trees, a light pruning can help balance the loss of roots. Remove only dead, damaged, or crossing branches. Do not over-prune! The leaves are needed to produce food for new root growth. For small trees and shrubs, this step is often unnecessary if you can save a good rootball.
Step 4: Dig Up the Tree with Care
Start by watering the tree’s soil thoroughly the day before digging. This helps hold the root ball together. Then, estimate the size of the root ball you need. A general rule is 10-12 inches of root ball diameter for every inch of the tree’s trunk diameter.
1. Use your shovel to cut a circle around the tree at this distance. Push the shovel straight down to slice through roots cleanly.
2. Once the circle is cut, start digging a trench around the tree just outside your circle. Go down until you’re below the main mass of roots.
3. Begin undercutting beneath the root ball, angling your shovel inward. Work your way around until the root ball is free.
Step 5: Handle and Move the Root Ball
Never lift a tree by its trunk! You must support the root ball. Carefully slide burlap or a tarp under the root ball. Gently tip the tree and pull the material around to cradle it. You can then lift or drag it to the new location. For heavier trees, use a cart or get helpers.
What to Do If Roots Are Severely Damaged
Accidents happen. If a major root is torn, use your pruning shears to make a clean cut. Ragged wounds are harder for the tree to seal. Once planted, ensure consistent watering and consider a light layer of mulch to retain moisture.
Step 6: Plant the Tree at the Correct Depth
Place the tree in the new hole, making sure the root flare (where the trunk widens at the base) is slightly above the surrounding ground level. This is non-negotiable. Backfill the hole with the native soil you removed, gently tamping it down to remove large air pockets. Water lightly as you backfill to help settle the soil.
Step 7: Water, Mulch, and Stabilize
After planting, create a small soil berm around the edge of the root ball to form a watering basin. Give the tree a deep, slow watering to saturate the root zone. Then, apply 2-3 inches of organic mulch like wood chips over the area, but keep it a few inches away from the trunk itself to prevent rot.
For larger trees, you may need to stake it for the first year to prevent wind from rocking it and breaking new roots. Use wide, flexible straps and remove them after one growing season.
Step 8: Post-Transplant Aftercare
The first year is crucial. Your tree is in recovery mode. Water it deeply once or twice a week, depending on weather, for the entire first growing season. Do not fertilize it this first year, as fertilizer can burn new roots. Just let it focus on establishing itself. Watch for signs of stress like wilted leaves, but be patient—transplant shock is normal.
Common Mistakes to Avoid
* Digging the hole too deep. This is the number one killer.
* Not watering enough. The root ball can dry out quickly.
* Over-mulching or “volcano mulching” against the trunk.
* Fertilizing too soon. Wait at least a year.
* Choosing the wrong season. Transplanting in summer is very risky.
FAQ: Your Tree Transplant Questions Answered
How big of a tree can I move myself?
It depends on your strength and tools, but generally, trees with a trunk diameter over 2 inches are heavy and difficult for one person. For anything larger, consider hiring professionals with a tree spade.
What are the signs of transplant shock?
Leaf scorch (browning edges), wilting, leaf drop, and stunted growth are common. Consistent, proper aftercare is the best treatment. Sometimes a tree will lose its leaves but bud out again later.
Can I transplant a tree in the summer?
It’s not recommended. The heat and the tree’s active growth put immense stress on it. If you must, do it on a cool, cloudy day and be prepared for intensive daily watering and a higher risk of failure.
How long before the tree is established?
A good rule of thumb is one year for every inch of trunk diameter. So, a 3-inch diameter tree will need about 3 years of attentive care before it’s fully settled.
Should I use root stimulator or mycorrhizal fungi?
While not strictly necessary, a root stimulator or mycorrhizal fungi powder applied at planting can encourage root growth and reduce shock. They are generally considered helpful aids.
Transplanting a tree is a rewarding project that saves a beautiful plant and enhances your landscape. By following this expert guide, preparing carefully, and commiting to the aftercare, you’ll greatly increase your chances of success. Remember, patience is your greatest tool as your tree adjusts to its new home.
