How to Plant a Norwegian Crimson King Maple

Overview

Norwegian Crimson King Maples (Acer platanoides) grow in U.S. Department of Agriculture Hardiness Zones 3b to 7 and can grow to be 35 to 45 feet tall with a spread of 25 to 40 feet. They have shallow roots, so surrounding grass may be difficult to maintain since the two are competing for the same water and nutrients.

Step 1

Select a planting site in a partially sunny area of your yard. Allow ample room for growth, especially in regard to power lines and neighboring houses. In addition, plant the tree at least 4 to 6 feet away from any sidewalks, driveways and foundations since its shallow roots can damage them if planted too close.

Step 2

Dig a hole that is about two to three times as wide as the root ball. The hole's depth should hold 2/3 of the root ball. According to U.S. Department of Agriculture, Norwegian Crimson King Maples grow well if 1/3 of its root ball is above the soil line.

Step 3

Amend the soil you just dug out, if necessary. Norwegian Crimson King Maples tolerate most soil types, but it should be well draining. For that reason, add several inches of compost, sand or peat moss to help with proper drainage.

Step 4

Remove the tree from the container or remove any burlap or netting around the root ball. Loosen up any tightly compacted dirt and roots with your hands.

Step 5

Place the tree in the center of the hole. Have a second person help you so one can hold the tree while the other back fills the hole with soil.

Step 6

Water the tree after back filling the hole half way. Tamp it down well to remove any air pockets. Continue to back fill until the hole is filled. If you planted the tree above the soil line, create a sloping mound from one inch above the root ball toward the ground. If you can still see the old soil line on the trunk where the tree was originally planted, use that as the top point for your soil.

Step 7

Water the tree again and tamp down the soil well with your feet.

Step 8

Place about three inches of mulch around the planting site to help retain water. Keep your tree well watered during the first growing season.
