适合新手

寿命

关于寿命的资料很少

体型

通常树高约3米，罕见达15米

浇水

肥料（2月下旬～3月上旬、结实后的4～8月。9月以后停止施肥）

光照·放置位置

林缘植物，半阴至明亮遮荫处合适。夏季用遮阳防止西晒叶烧，9月后充分光照促进红叶和果实着色。

浇水

喜水性强。春秋季每日2次，夏季2～3次，冬季每隔2日1次为目安。7月中旬后吸水减弱，按干燥情况判断。开花期勿向花喷水。

温度·越冬

虽然抗寒性强，但本树含水量大，冬季易发生枝干枯死和根冻。落叶后需用土洞等设施保护。

用土·换盆

根系生长快，1年内填满花盆。3月中旬或9月进行，幼树每年换盆，成形树每1～2年换一次。

肥料

结实树需充分施肥。油渣中混入骨粉补充磷酸。9月以后停止施肥以促进果实着色。

修剪·整形

保留一定数量的徒长枝以充实短枝，8月上旬～9月上旬剪除徒长枝。基本上无需进行细微的摘芽。

病虫害·注意事项

注意蚜虫、飞虱、介壳虫、卷叶虫。由于是雌雄异株，需准备交配用的雄树。每年结实过多会导致树势衰退。种子有毒。

关于尖叶卫矛

Mayumi is a deciduous spindle tree whose pale pink fall fruit splits open to reveal red seeds, with vivid autumn leaves. Beginner-friendly, though a male tree is needed nearby for reliable fruiting.

开始养护尖叶卫矛前需要了解的7件事

1. 1Partial Shade to Bright Shade

   Mayumi naturally grows along forest edges, so partial shade to bright shade suits it. In summer, use shade cloth to protect it from afternoon sun and leaf scorch. From September on, give it plenty of sun to bring out autumn color and help the fruit color up.

2. 2Watering Basics

   Water thoroughly once the soil surface has dried, which is the general rule for this species. It dries out faster during the spring-to-fall growing season, so watch for underwatering, while lighter watering is fine once the leaves have dropped.

3. 3Choosing Soil

   Choose a soil mix that balances drainage with water retention. A standard bonsai mix based on akadama with some leaf mold works well for mayumi.

4. 4When to Repot

   Mayumi's roots grow quickly and can fill a pot within a year. Repot young trees every year and mature trees every one to two years. The best times are mid-March or September.

5. 5Seasonal Pruning

   Trimming unwanted branches while the tree is bare in the dormant season helps shape next year's form, foliage color, and fruiting. During the growing season, trim back overly long shoots as needed to maintain the silhouette.

6. 6Picking Male vs. Female

   Mayumi is dioecious, so if you want reliable fruiting you'll need both a female tree and a male tree nearby for pollination. Confirming which sex a tree is at the time of purchase can save you from being surprised later when a female tree alone fails to fruit.

7. 7Enjoying Foliage and Fruit

   In autumn mayumi offers both colorful foliage and fruit that splits into four sections to reveal red seeds inside. Keeping up with the basics — good light and air circulation — helps bring out strong autumn color and a good fruit set.

尖叶卫矛的常见问题

Q.Is mayumi easy to grow for beginners?

A.Mayumi is generally considered a beginner-friendly species. As long as you keep up with basic light and watering care, it's manageable even for those new to bonsai.

Q.How do I get mayumi to fruit every year?

A.Because mayumi is dioecious, a female tree alone often won't set fruit reliably. Keeping a male tree nearby for pollination makes fruiting more consistent.

Q.How large does mayumi grow?

A.As a bonsai or garden tree, mayumi typically stays around 3 meters tall. In rare cases it can grow as tall as about 15 meters.

Q.When is the best time to repot mayumi?

A.Repot in mid-March or in September. The roots grow fast enough to fill the pot within a year, so repot young trees every year and mature trees every one to two years.

Q.Can I enjoy both autumn leaves and fruit at the same time?

A.Yes, mayumi offers both attractive autumn foliage and fruiting at the same time of year. As the fruit ripens it splits into four sections to reveal red seeds inside, adding to the seasonal display alongside the leaf color.
