It is hard to believe that a meter-high deciduous tree can develop from an initially small cutting within a very short time. The robinia literally shoots up. The false acacia, as it is also called, shows considerable growth, especially in the first few years. Here you will find precise information on the annual growth of the robinia.
Robinia can grow up to 30 meters high
The annual growth
Black locust grows very quickly, especially when young, as the following table shows.
- Growth in the first ten years: 1-1.2 meters per year
- from ten years: 0.25-0.5 meters per year
- from forty years: 20 centimeters per year
Influence of site conditions
Considering that a robinia can live up to 300 years, it explains why its crown soars almost unreachably into the sky. Unfortunately, the growth of the deciduous tree is not unlimited. Various factors and environmental influences inhibit growth. The maximum growth height is 20-30 meters, but only occurs under optimal conditions. To create this height, the robinia should be in groups. As a free-standing tree, it reaches a maximum height of only 12-20 meters. In addition, a location in an urban area or on busy roads leads to premature aging of the wood. Here the deciduous tree lacks oxygen to develop well.
