Alias: Holly Euonymus, Zhengmu.
Scientific name: Buxus microphylla Sieb. et Zucc.
Family: Buxaceae.
Tree species characteristics: Boxwood, also known as melon seed boxwood or millennium dwarf, is an evergreen shrub or small tree. It has gray and white trunks, dense branches with four-angled stems. The leaves are opposite, leathery, entire, elliptic or obovate, with a rounded or slightly indented tip. The upper surface is bright green, while the lower surface is yellow-green. Flowers appear in clusters at the leaf axils or on branches, blooming from April to May, with yellow-green blossoms. The fruit is oval.
This genus includes varieties such as Cyclovirobuxine, which features spoon-shaped or inversely lanceolate leaves with a dark green, glossy surface, and Pearl Boxwood, an evergreen shrub with shiny, elegant leaves. These two types are highly valued for bonsai cultivation due to their beautiful forms and natural grace.
Boxwood is native to central China, growing wild below 1300 meters above sea level. It is widely cultivated in the Yangtze River basin and its southern regions. It thrives in full sun but can tolerate shade. It prefers fertile, loose, moist soil and can adapt to acidic, neutral, or slightly alkaline conditions. It grows quickly and is highly tolerant of pruning.
Bonsai Production
(1) Material Selection
Seedlings grown from seeds or cuttings can be transplanted and shaped over several years. Alternatively, old trees can be collected from the wild. After digging, trim long roots and dense branches, then expose them to the ground for 1–2 years before potting.
(2) Potting
1. Pot Selection: Use Zisha pots in purple or light yellow tones. The shape should match the tree’s form—deep pots for cliff-style bonsai, oval or rectangular pots for slanting or curved trunks.
2. Soil Mix: A combination of matured garden soil or leaf mold with some ash is ideal. The soil should be fertile, well-draining, and loamy. For old trees, use a similar mix.
3. Planting: Cyclovirobuxine is cold-resistant and can be planted in early spring before new growth. Trim overly long roots and avoid root congestion in the pot. Place newly planted boxwood in partial shade.
(3) Shaping
Boxwood has strong regrowth ability. Before shaping, you can prune the trunk and create new techniques around or below the cut. Then, train the branches according to artistic design. Use brown silk for tying in spring. You can also thin the branches to create cloud-like shapes or flat, neat forms, or let it grow naturally. The trunk can follow its natural direction to create an inclined or leaning style. When paired with rocks, it becomes a "yellowhead" effect. Boxwood is very easy to prune and regrows quickly, so regular maintenance is essential to keep its beauty.
Maintenance Management
(1) Watering
Boxwood prefers moist conditions. Keep the soil consistently wet but avoid waterlogging. In summer, water in the morning and evening, and mist the leaves regularly.
(2) Fertilization
During the growing season (May to August), apply 2–3 doses of diluted composted manure. In winter, add one base fertilizer, such as fermented manure or dried cake fertilizer.
(3) Pruning
Throughout the growing season, remove leggy, overlapping, or excess branches that affect the tree's shape. After new shoots develop, pinch back the tips by 1–2 nodes to prevent elongation. Remove fruits promptly after they form to conserve energy and promote healthy growth.
(4) Repotting
Repot every 2–3 years, preferably before spring sprouting. Trim old and overly dense roots, replace half the soil, and repot into loose, nutrient-rich soil to encourage root development.
(5) Pest Control
Common pests include scale insects and boxwood caterpillars. Scale insects can be removed manually or sprayed with 80% dichlorvos at 1500 times dilution. Caterpillars can be controlled with 80% trichlorfon powder or 40% omethoate at 1000–2000 times dilution. The main disease is sooty mold, which causes leaf drop. Prevention involves removing scale insects and regularly spraying the leaves to remove dust and maintain health.
Boxwood bonsai is admired for its elegant posture, small, thick, and glossy leaves, and its evergreen nature, making it enjoyable year-round. Poplar bonsai, with carefully pruned branches and leaves shaped like clouds, combined with rocks, creates a refined and picturesque scene.
In spring, young boxwood leaves emerge, covering the tree in lush greenery, offering a visually pleasing sight. Ancient poets often wrote about the poplar, closely associating it with this tree. Its graceful appearance makes it an excellent choice for bonsai enthusiasts who enjoy cultivating and appreciating nature's beauty.
