You can transplant a Japanese maple up to 5 feet tall yourself. For larger trees, you will need the help of specialized companies that have heavy equipment.
Tips on how to transplant Japanese maple
- Dig up the Japanese Maple within 2 feet of the trunk.
- Only transplant in early spring during cloudy weather.
- The day before transplanting, water the tree with 2-3 gallons.
- Dig to damage as few roots as possible.
- Once dug up, move the Japanese Maple to its new location immediately.
- Place the root ball in the hole so the trunk is not buried in the ground.
- Backfill the entire space with improved soil and tamp it down lightly.
- Water the Japanese maple with 2 gallons of water and mulch the surface with organic material.

When to transplant?
The best time to transplant Japanese Maple is early spring. You need to catch the period when it is a little warmer, and the ground is not frozen, but the tree is still in hibernation. The buds should not be pushing yet.
Avoid transplanting in late spring when leaves have already appeared. Also, do not transplant in the summer. Otherwise, you risk losing the tree.
As for the weather, an overcast day with a bit of rain the day before is best. The milder the weather, the easier the Japanese maple will transplant.
Evening or morning is the best part of the day to move. Avoid transplanting in the afternoon, especially if the day is sunny.
Also, do not transplant the maple more often than once every three years. The tree you want to transplant should grow in the same place for at least two years. Japanese maple can be transplanted no more than three times in its lifetime.
Before transplanting
The first thing you should do before transplanting is to water the Japanese maple. Of course, you have to do this if it hasn’t rained in a few days.
Water with 2-3 gallons of water 1 day before transplanting. This will allow the tree to accumulate moisture and tolerate the first few days more easily. Also, moist soil will hold the roots better, which is very important.
The second thing to do is to dig a planting hole in the new location. This should be done in advance so the maple can be moved and planted without delay.
The new hole should be twice the size of the root ball. The new location should get at least four hours of direct sunlight daily. Also, there should be no stagnation or accumulation of water.
The soil should preferably be loose and well-drained. The distance to other trees should be at least 3 feet.
Mix the excavated soil from the new hole with the same quality compost or soil conditioner. Place this soil mix on the side of the hole.
Prepare a clean and sharp trench shovel. You will also need a burlap or other thick material.
How to dig up and replant?
No matter how small the Japanese Maple is, start digging at least 1 foot away from the trunk. You need to save as much root mass as possible.
For 3 to 5-foot tall maples, the distance from the trunk where you need to dig should be at least 2 feet. This will result in an initial root ball diameter of 4 feet. However, in the process of digging and moving, some of the soil will fall away from the roots, and the root ball will be about 3 feet wide.
In general, the more roots you save, the better the chances for successful rooting of the maple. If the root ball is too heavy, get someone to help.
Place the root ball on a piece of burlap and tie the opposite ends diagonally together. You can use any other sturdy material instead of the burlap. The burlap will help to ensure that as little earth as possible falls off the roots as you move the maple.
Move the Japanese Maple quickly to its new location. Do not allow the soil on the roots to dry out. You can use a wheelbarrow for this purpose.
Sprinkle some soil into the planting hole and place the maple there, but remove the burlap from the roots first. The surface of the root ball should be about 1 inch above the surface of the garden around it. If necessary, pour some more soil under the maple.
Next, fill the entire space in the hole with the prepared soil mix and gently compact it. Do this with your foot, but do not damage the roots.
Water the newly planted maple with 2 gallons of water. When the water has soaked into the soil, water another gallon.
After transplanting
The first thing to do after replanting is to mulch the root zone. Use organic materials such as pine bark or compost.
The thickness of the mulch layer should be about 2 inches. You do not want to bury the trunk of the Japanese Maple in the mulch. There should be a gap of about 2-3 inches between the trunk and the mulch material.
For the first two years, regularly monitor how wet the soil in the root zone is. Don’t let the soil dry out more than 1-2 inches. Use at least 1 gallon of water when watering.
If the weather is very sunny and hot after transplanting, put a shade over the maple for 1-2 months. You can do this with a large umbrella or shading net.
Do not cut back the branches after transplanting. Pruning will only increase the stress experienced by the tree.
You also do not want to use any fertilizer on the transplanted maple. In the first year, the tree will be rebuilding its root system and does not need any fertilizer. Also, you should not expect vigorous growth in the first growing season.
