Yes, this tree can grow indoors; however, a dwarf Alberta spruce can reach up to 13 feet tall, so the plant will likely outgrow your space. These plants do not like too much humidity, and they prefer cooler temperatures. If you are caring for a dwarf Alberta spruce indoors, make sure to water these plants thoroughly. In the winter, when the sun exposure is less and the plant is not in its growing season, reduce watering significantly.
