The planting season for white spruce in the sub-boreal forests is limited by snow and frozen soil in both the spring and the fall. Conventionally the season is terminated in late June because of hot weather and resumes in mid-September when nursery stock has hardened - off.
To determine whether planting can continue throughout the growing season on high sites, a three year trial was conducted within the Crooked River Provincial Forest of the Prince George Forest District using freshly-lifted and cold-stored seedlings of white spruce.
The results indicate that under carefully regulated conditions, freshly-lifted seedlings can be planted successfully from July onwards, and that the performance of cold-stored seedlings decreases steadily and they should not be planted after mid-July. By combining these findings, planting can be continued throughout the entire growing season.
