Blue Spruce
Advanced Level
Care Profile
A Blue Spruce Bonsai (Picea pungens) is a majestic evergreen conifer prized for its striking, silvery-blue to blue-green needles and rugged bark that lends itself well to classic bonsai styles. While its general care requirements are simple (full sun, outdoor placement, and plenty of water), it is considered an intermediate to advanced subject due to its slow styling response and the difficulty in establishing pads and strong branch structure.
