Types of Boxwood Bonsai
Over 70 types of boxwood trees exist, but the Chinese and European common boxwoods reign supreme in bonsai. It's crucial to know the distinctions between the two species to provide the correct care.
Common European Boxwood (Buxus sempervirens)
Europe-wide, boxwood is a popular landscaping plant. It's trainable and the faster-growing species. Boxwood grows outside and tolerates frost. If temps drop below freezing, transfer it somewhere cool to overwinter.
Boxwood is dormant in winter and doesn't need fertilizer. Evergreen boxwood retains leaves all winter. Light frosts may yellow or pale the leaves, but they'll return in spring.
Chinese boxwood (Buxus harlandii)
Although hardy, Chinese boxwood is more fragile than its European cousin. This species thrives indoors but prefers the outdoors in warmer months. A Chinese boxwood should never be left outside to overwinter; instead, place it in a cool location with temperatures around 50 degrees F. These trees don't go dormant and need monthly fertilization.
