Abstract
The regeneration and growth of pruned roots of Douglas-fir seedlings were studied under nursery conditions. Root pruning did not decrease the height increment of seedlings. For the best development of dense and compact root systems, the bottom pruning should be done early in spring and the side pruning around the middle of June, on both sides of the row simultaneously.
