矮紫杉

矮紫杉的基本資料

栽培難度

適合新手

壽命

壽命長，大山有樹齡600年的老木群生

體型

高0.5～2公尺，橫向展開的灌木（盆栽為迷你～中等品種）

澆水

肥料（4～5月及9～10月）

光照與放置位置

喜陽光但耐半蔭。夏季應置於避開強日照、明亮通風良好之處

澆水

怕乾旱。春季每日1～2次，夏季2～3次，秋季1～2次，冬季每2～3日1次為目安。夏季過濕也會導致根腐

溫度與越冬

耐寒（紫杉屬USDA 4區）。寒冷地區冬季葉片變褐，但翌年恢復綠色。耐熱性優於紫杉

培土與移植

用土不挑剔，但使用赤玉土單用或混砂以確保排水良好。移植於3月中旬～4月中旬進行，成樹以2年1次為目安

肥料

除梅雨和夏季外，於4～5月及9～10月每月施用1～2次有機質肥料

修剪與整姿

新芽於4月中旬～6月趁柔軟時用手指摘去，保留一半至三分之一。修剪於3～4月及10～11月進行，布線於10月～3月，去除老葉於10～11月

病蟲害與注意事項

病蟲害不多，但持續乾燥會引起紅蜘蛛。漿果種子有毒。為野生種，應選擇栽培品而非野採品

關於矮紫杉

Dwarf Japanese yew, a spreading variety of Japanese yew from the snowy mountains of Japan's coast, is prized for its low, fanning form and broad spiral needles, a heat-tolerant conifer that's easy for beginners to grow as bonsai.

開始照料矮紫杉前需要了解的7件事

1. 1Light and Air Circulation

   Dwarf Japanese yew tolerates partial shade but keeps its densest, most attractive form in good light. Strong afternoon sun in midsummer can scorch the foliage, so move potted specimens somewhere with afternoon shade and good airflow.

2. 2Watering Basics

   Water thoroughly once the soil surface dries out. Because it naturally grows in snowy, moisture-rich mountain terrain, it's less drought-tolerant than some conifers, so summer heat may call for watering both morning and evening.

3. 3Well-Draining Soil

   Choose a bonsai soil mix that balances drainage with moisture retention to avoid root rot. A base of akadama with added leaf mold and pumice is a common, reliable combination.

4. 4Repotting Schedule

   Growth is relatively slow, but repotting every two to three years prevents the roots from becoming pot-bound. The best windows are just before spring budding or after the autumn equinox.

5. 5Winter Care, Pinching, and Pruning

   This tough conifer can overwinter outdoors, though it's best kept out of harsh, dry winds. Pinch new shoots by hand from mid-April to June while they are still soft, leaving a half to a third of each shoot. Do pruning cuts in March to April and October to November to keep the silhouette neat.

6. 6A Naturally Spreading Form

   Because the trunk doesn't grow upright and instead branches from the base, bonsai growers often train it into informal upright or windswept-style shapes that emphasize its natural horizontal spread. Wiring is easiest while branches are still young and pliable, before they thicken and stiffen.

7. 7Choosing a Young Plant

   Look for glossy, healthy-colored foliage and multiple branches emerging near the base, which makes it easier to develop a natural spreading form. The broad, spirally arranged needles are the key feature that distinguishes it from ordinary yew.

矮紫杉的常見問題

Q.How is Dwarf Japanese yew different from regular yew?

A.It's a variety of Japanese yew whose trunk doesn't grow upright but instead branches from the base and spreads horizontally. Its needles are also broader and arranged in a spiral, which is the easiest way to tell it apart.

Q.Is it suitable for beginners?

A.Yes, it's a hardy, relatively heat-tolerant conifer considered good for beginner bonsai growers. As long as you keep up with basic watering and give it enough light, it's fairly forgiving.

Q.How large does it grow?

A.In the wild it forms a low shrub about 0.5 to 2 meters tall, while as bonsai it can be trained from mini to medium sizes. Its slow growth rate also makes the size easier to manage over time.

Q.Can it stay outdoors through winter?

A.Yes, it's cold-hardy enough to overwinter outdoors. Just avoid prolonged exposure to dry, cold winds, which can damage the foliage.

Q.How long can I expect to enjoy this tree?

A.It's known for being long-lived, with colonies of trees estimated at 600 years old still growing on Mount Daisen. With good care, it's the kind of bonsai that can be passed down and enjoyed for generations.
