Their growth rate is generally divided into three categories. Slow-growing conifers grow less then 12 inches per year. A medium or moderate growth rate is between 1 and 2 feet per year.
Fast-growing conifers grow at least 2 feet per year. Tree growth slows in autumn and usually stops in winter, and then starts again in spring; this causes annual 'rings' to appear in the cut timber, from which the age can be determined.
