How to Propagate Crimson King Maple


The crimson king Norway maple tree is a variety that is known for the green-purple foliage it produces through out the summer season. The tree produces spring-time maroon-yellow flowers that turn to helicopter-wing shaped seeds. The crimson king Norway maple is propagated through seed collection in late summer and fall. The seeds must be planted after collection and sowed outdoors in fall because they require a wintering period to germinate.

Step 1

Collect the maple seeds by gently removing them from the tree branches. Place the seeds in a paper bag or envelope and label the collection date and plant species. Do not use plastic bags as they retain moisture and cause seed rot.

Step 2

Separate the two helicopter winged maple seeds if they are still attached. The seeds do not need to be separated from the wings.

Step 3

Rake a seed-starting location to remove debris and rocks. Press the seed into the soil at a depth that is the same as the diameter of the seed. Lightly cover the seed with sand or sifted soil.

Step 4

Apply a thin layer of leaf or straw mulch over the seed to prevent the seed from being washed away.

Step 5

Water the seed well after planting in the fall season. Water the seed area again in the spring when the soil appears dry.

Step 6

Mark the planting location to protect the seed and seedling growth.
