The Douglas fir from the nursery is often only half a meter high. It's an acceptable start, but the goal is a stately tree. The expectations of the purchased copy are therefore high. How many cm will it gain per year?
How much does a Douglas fir grow per year?
The annual growth of a Douglas fir under optimal conditions is around 40 cm, while under less than ideal circumstances it is closer to 20 cm. Factors such as location, soil quality and irrigation influence growth.
A fast growing species
The Douglas fir is considered a fast-growing tree species that easily surpasses the native spruce. You can expect this annual increase:
- ideally with approx. 40 cm
- under less than optimal conditions, more like 20 cm
Location as a growth factor
The annual growth of a Douglas fir depends closely on its living conditions. An unsuitable location slows down growth, and an unfavorable one can even cause it to collapse completely.
Ideal growing conditions
The Douglas fir, which comes from North America, likes sunny to semi-shady places in this country. If it is also allowed to extend its roots into fresh, moist and nutrient-rich soil, it will offer maximum height growth.
Tip
Pay attention to regular watering, especially for young trees, which must not be interrupted even in winter.
