Planting a Japanese MapleJapanese Maple Planting Diagram

Depending on the lay of the land, there are generally two different methods for planting a Japanese Maple. One method is for planting on level ground and the other for planting on sloped ground.

Planting On Level Ground

  • Before planting, test the soil in the area for drainage. Dig a hole 12 inches deep and wide. Fill with water and see how long it takes the water to drain. If the hole drains in just a few hours or less its well-drained. If within 6 to 12 hours it's moderately drained. Anything over that means its poorly drained and steps might need to be taken to improve drainage.
  • If you are planting a container-grown Japanese maple in average garden soil on level ground, begin by digging a hole 2 to 3 times as wide as the root ball or container that the maple is growing in, and about 2/3 as deep as the root ball. Place soil removed from planting hole around outside of of hole.
  • Next, thoroughly mix 1/3 to 1/2 part organic soil amendment, such as mushroom compost, with the native soil removed from hole and break up any clumps or clods as you mix.
  • Next, remove your Japanese maple from the container it was growing in. You may need to use a utility knife to cut container off. Scratch the surface of the root ball to loosen the feeder roots. Do so gently so not to damage the root system
  • Next, if the soil is well- or moderately drained, place the root ball in the planting hole with 1/4 to 1/2 of the root ball above the ground level. (If the soil stays soggy for more than 24 hours after a heavy rain, and there's nothing that can be done to improve drainage, I usually set the root ball on top of the ground.) Add some backfill soil mixture to bottom of hole if necessary to achieve proper height. Also, stand back away from the tree to make sure it is properly positioned. Rotate if necessary to achieve best position and level.
  • Next, begin backfilling the planting hole by pulling soil around the root ball, tamping lightly as you go to remove any air pockets. When the hole is half-filled, soak with water and then resume backfilling. Backfill to top edge of rootball tapering your soil mixture to existing ground level as shown in the diagram to the right. Essentially, you will be creating a raised mound around the root ball. Do not place any of the backfill mixture on top of the root ball. Do not add fertilizer at this time (although a transplant solution with Vitamin B1 may be beneficial.)
  • Next, use remaining soil mixture to build a water retaining berm around the outside perimeter of the planting hole. This berm will help to catch water from rainfall during the first and second growing season as your tree is becoming established. After the second season the berm can be removed.
  • Next, water deeply.
  • Next, apply a 2" layer of aged, shredded wood mulch or bark or up to 4" layer of pine straw around your newly planted tree. Make sure not to place mulch against the trunk as this can cause disease or other damage - leave a 2" space between mulch and trunk.
  • Next, stake your tree if necessary. Shorter trees usually do not require staking.
