Scientific/Botanical Name Buxus sempervirens
Description There are more than 70 species of boxwood. The common boxwood is hardy and gains height rapidly. It works best for bonsai shaping. The root system is shallow, and the bark is thin.
Position A semi-shady position is the best growing site. In its natural environment the plant occupies a position under tree canopies. Excessive sunlight can burn the leaves of the plant. The boxwood bonsai is not tolerant of temperatures below minus 4oCentigrade.
Watering Water the plant as needed to keep the soil moist but not soggy. Reduce watering dramatically during the fall and winter.
Feeding Feed boxwood bonsai with a bonsai fertilizer during the growing season.
Leaf and Branch Pruning Regular thinning and pruning of the internal branches will encourage back-budding and the retention of leaves. The thinning of leaves will cause growth of shoots, which can then be trained into the desired shape. Common boxwood tolerates hard pruning exceptionally well.
Re-potting & Growing Medium The plant should not be re-potted any sooner than two years, and three years may be optimal. If re-potted sooner, its growth will be extremely vigorous.
Wiring Shape with wire while the buds are still soft, and the plant is pliable. Monitor the plant so as to prevent damage to the new bark that develops.
Notes The boxwood plants found at nurseries and garden centers can be readily trained as bonsai specimens
