粗皮槭的基本数据

养护难度

适合中级者

寿命

作为品种的寿命资料较少

体型

在盆栽中流通范围从小品到大品（关于成木尺寸的资料较少）

浇水

肥料（春季和秋季）

光照·摆放环境

光照充足且通风良好的地方。由于忌讳西晒，从梅雨季结束到9月上旬应进行50～70%左右的遮光以防叶片灼伤

浇水

叶片展开后干燥很快。春季每天2次，夏季2～3次，冬季1～2天1次，向株基部浇水。夏季缺水会影响红叶质量

温度·越冬

抗寒性强（日本槭为USDA 5区）。落叶后经受2～3次霜冻，然后需避开干燥风和迟春霜冻进行保护

培养土·换盆

使用排水良好的培养土，换盆在3月上旬芽萌动前进行。每2～3年换1次，迷你盆栽每1～2年换1次，梳理根系以增加细根

施肥

新叶长硬后的4月中旬施有机肥，5月追肥。秋肥在8月中旬～9月结束，促进红叶着色

修剪·造型

因为树干表皮是观赏重点，应最小化使用金属丝，通过芽摘（3月中旬～4月中旬）和修剪来塑造树形。粗枝在芽萌动前修剪，细枝在落叶前后修剪

病虫害·注意事项

新芽易遭蚜虫和介壳虫危害，梅雨期后易发生白粉病。叶片较薄容易产生药害，施用药剂时应严格按标签浓度

关于粗皮槭

Arakawa is a Japanese maple bonsai known for its rough, craggy trunk, visible even in young trees. Unlike smooth-barked maples, it stands out at a glance. Suited to intermediate growers.

开始养护粗皮槭前需要了解的7件事

1. 1Give It Full Sun

   Arakawa does best outdoors in a spot with plenty of sun and good air circulation. Full light and fresh air help keep growth compact and branches well-formed. Just shield it from harsh summer afternoon sun and hard winter frost by moving the pot as needed.

2. 2Never Let It Dry Out

   Maples are thirstier than many other bonsai species and don't tolerate drying out well. Water thoroughly as soon as the soil surface dries, especially in summer, before leaf tips start to scorch. Arakawa's watering needs follow the same basic rules as any Japanese maple.

3. 3Well-Draining Soil

   Like other maple bonsai, Arakawa prefers an akadama-based mix that balances good drainage with enough water retention. Aim for soil that avoids waterlogging and root rot without drying out too quickly either.

4. 4Repot During Dormancy

   The best time to repot is during winter dormancy, ideally just before spring buds break. Young trees tend to fill their pots with roots quickly, so repotting roughly every one to two years helps keep the tree vigorous.

5. 5Pruning and Fall Color

   Like other maples, Arakawa offers seasonal appeal through fresh spring foliage and vivid autumn color. Structural pruning is best done during the leafless dormant season, and sealing cut ends with wound paste helps prevent dieback.

6. 6Choose by Bark Texture

   When selecting an Arakawa, look closely at the bark's texture and pattern, since the degree of roughness varies from tree to tree even within the same variety. Picking a specimen whose bark character matches your taste and future styling plans will help you find one you're happy with long-term.

7. 7From Shohin to Larger Sizes

   Arakawa is grown as bonsai in sizes ranging from small shohin specimens up to larger trees. Since the size you choose affects how much space and care it needs, it's worth matching the scale to your own growing environment.

粗皮槭的常见问题

Q.What makes Arakawa different from a regular Japanese maple?

A.The main difference is the bark. Ordinary maples keep smooth bark as they grow, while Arakawa develops a rough, craggy trunk texture even while young, making it visually distinct.

Q.Can beginners grow Arakawa?

A.Arakawa is generally considered suitable for intermediate growers rather than complete beginners. The basic care overlaps with maples in general, but some prior experience with watering timing, pruning, and repotting will make it easier to manage well.

Q.At what age does the rough bark start to show?

A.Arakawa is known for developing rough bark texture even while still a young tree, which is one of its defining traits. That said, how quickly this progresses varies from tree to tree, and little has been documented about a typical timeline for the cultivar.

Q.What bonsai sizes is Arakawa suited to?

A.Arakawa is trained into bonsai across a wide range of sizes, from small shohin to larger specimens. Being able to choose material to match your intended size is one of the practical advantages of this variety.

Q.Does Arakawa have appeal beyond its bark?

A.Aside from the bark texture, Arakawa shares the same general appeal as Japanese maples, including spring foliage and autumn color. Its standout trait is how it lets even young material take on the presence of an old, weathered tree.
