How Fast Does a Crimson King Maple Grow?

Acer platanoides, or Crimson King maple, grows throughout most of the United States with the exception of some coastal areas, including Florida and parts of California and Texas. It produces crimson or purple leaves in the summer and exhibits a moderate growth rate.

Annual Growth

A moderate or medium growth rate means that the Crimson King maple grows between 1 and 2 feet per year, according to Utah State University Extension.

Slow Growth

The Crimson King maple sometimes grows very slowly, according to Iowa State University Extension. Plant this tree in full sun in nutrient-rich, moist, well-drained soil to encourage maximum growth.


The Crimson King maple reaches a height of 35 to 45 feet with a 25- to 30-foot width, according to the University of Florida Extension.

Long Does It Take For A Crimson King Maple Tree To Take Root?

Crimson King maples propagate best from softwood cuttings, which must be gathered and struck in late spring or early summer before the seasons' new growth has hardened. Choose a 6- to 8-inch-long cutting from the tip of a branch with no more than four pairs of leaves. Most softwood cuttings root easily on their own, but some light preparation will help Crimson King maple cuttings root faster and with better results. Keep the medium moist but not sopping wet, and mist the cutting twice daily to keep the leaves plump and hydrated. Cut open the plastic freezer bag and leave it in place for one or two days. Prop open the hole for an increasing long period of time each day before completely lifting the bag after one week. Transplant the Crimson King maple into a 2-gallon pot filled with soil and grow it in a sheltered spot for one full year before planting it in a permanent bed in autumn.
