Boxwood (Buxus sinica), also known as littleleaf boxwood, thousand-year dwarf, etc., is an evergreen shrub or small tree of the genus Buxus in the family Buxaceae, native to the middle Yangtze River basin of China and the regions to its south. It likes warm, semi-shaded, humid climates, is drought-tolerant, cold-tolerant and tolerant of pruning, is a shallow-rooted tree species, grows slowly and lives long, and is an excellent tree material for making bonsai. Care management: Boxwood likes moisture and needs frequent watering to prevent leaf drop caused by water loss. From May to August is the vigorous growth period of boxwood, and several applications of thin, fully decomposed cake fertilizer can be made along with watering. Always pay attention to pruning

It likes warm, semi-shaded, humid climates, is drought-tolerant, cold-tolerant and tolerant of pruning, is a shallow-rooted tree species, grows slowly and lives long, and is an excellent tree material for making bonsai.

Care management: Boxwood likes moisture and needs frequent watering to prevent leaf drop caused by water loss. From May to August is the vigorous growth period of boxwood, and several applications of thin, fully decomposed cake fertilizer can be made along with watering. Always pay attention to pruning water sprouts, overlapping branches and surplus branches that affect the tree's shape. Promptly remove the fruits set by the boxwood to avoid consuming nutrients. As for the repotting time of boxwood, generally small and medium bonsai can be repotted once every 2 to 3 years, and large pots once every 5 years; weak-growing plants should be repotted in time. Along with repotting, cut off some of the excessively long and dense old roots, replace with fresh growing medium and replant.

Pest and disease control: The main pests and diseases of boxwood are scale insects, leaf-roller moth larvae and sooty mold. To control leaf-roller moth larvae and scale insects, spray with 80% dichlorvos at 1500 times dilution; the key to controlling sooty mold is to frequently spray water on the leaf surface to wash off dust.

The boxwood bonsai has dense branches and leaves and stays green all year round. It is not only a good decorative plant for indoors, but also has a strong ability to absorb toxic gases such as sulfur dioxide, chlorine, hydrogen sulfide and hydrogen fluoride, and has the ability to absorb toxic gases and purify the air, making it a veritable indoor "evergreen purifier".
