white spruce

White spruce (Picea glauca 'Cecilia') should be watered once or twice a week depending on the time of year and the growing conditions. In the spring and summer, when temperatures are between 60 to 80 degrees Fahrenheit, water the white spruce so that the top 3-4 inches of soil are moist. In the fall and winter, when temperatures are below 60 degrees Fahrenheit, water only enough to keep the soil slightly damp. When watering, water deeply to promote deep rooting.

The amount and timing of sunlight required by white spruce (Picea glauca 'Cecilia') will depend on where it is located. In general, this plant species prefers full sun, meaning that it should receive at least 6 hours of direct sunlight each day. It is important to note, however, that this species is quite tolerant of partial shade, so it can still thrive with less sunlight in more northerly locations. For optimal growth and health, white spruce should continue to receive a steady 6 hours of daily sunlight even during the summer months. If the plant is exposed to too much sunlight in the summertime, it may become scorched or burned, so proper care must be taken to ensure it is not exposed to more than necessary. In addition, it is important to note that white spruce does not require direct sunlight throughout the day to thrive. In fact, this species tends to do best if it receives direct sunlight in the morning and indirect sunlight in the afternoon. This will help it to avoid sunburn and overheating later in the day.

White spruce (Picea glauca 'Cecilia') should be pruned in the late fall or early spring before active growth begins. Pruning should be limited to removing old, damaged or non-productive branches and maintaining desired shape. Avoid shearing or cutting too closely to a branch tip as this can cause new shoots to become too dense and can weaken the branch and reduce growth. Pruning should occur no more than once or twice per growing season.
