|We just purchased 2 Spiral Dwarf Alberta Spruce trees and wanted to plant them in containers in front of our garage which faces South and receives full daily sun in zone 5. What size does the container need to be? How deep,wide? They are beautiful specimens and we want to keep them that way, but this is the first time working with an evergreen so we are unsure.

|Dwarf Alberta spruces are very slow growing - only 2-4 inches per year - but will eventually reach 6' in height. I think plants look best when the container is about one third as tall as the entire plant. So if your plants are currently 3 feet tall, use a container that is at least 12-18 inches tall. If your plants are 5' tall, use a container that is 18-24 inches tall. The spruces' will have ample room for root growth and they won't look top heavy or lost in the wrong sized container. Hope this helps you decide on the size of container. Of great importance is that the container have adequate drainage holes. Enjoy your new plants!
