When do trees grow?

Radial stem growth of trees is limited to a relatively short time period of the year in spring and summer. The timing of the growth period depends on site and species and is mainly explained by the local temperature conditions. Norway spruce trees at the subalpine site Davos start their radial stem growth about one and a half months later than the pine trees in the Valais. The length of the growth period, however, is similar.
