寿命

关于品种寿命的资料较少（该品种多见于名贵盆景）

体型

盆景中可制作成小品至大品

浇水

施肥（4月、花后6月、9~10月）

光照和放置位置

喜阳光，但夏季强光会导致叶焼和根伤。幼树需充分日照，成型阶段可放半阴处。需保证通风。

浇水

喜水但根系细弱，怕过湿。春季每天浇1~2次，夏季2~3次，冬季2~3天浇1次为准。避免在高温日中浇水。

温度和越冬

有耐寒性但不耐冬季寒风。在檐下等地保护，防止盆土冻结。

用土和换盆

以鹿沼土为主的酸性粗质土壤。换盆在花后立即进行（6月）或秋季（9月下旬~10月上旬）。秋季换盆的株冬季保护要谨慎。

肥料

新芽硬化的4月左右、花后6月、9~10月每月施用1次固形肥料。肥料不足会导致枝条枯死。

修剪和造型

花芽形成于7~8月中旬，所以摘芽和修剪要在花后6月底前完成（关东以西地区可至7月初）。绑扎在4月和9~10月进行。

病害虫和注意事项

该树种容易遭受多种病害虫。易染扁虫、红蜘蛛、蚜虫和蓟马，生育期应定期防治。

关于晃山

Kozan is a classic satsuki azalea of unknown lineage, cultivated since before the Meiji era. It bears small brownish-pink flowers and grows vigorously, making it well suited to bonsai training in sizes from small to large.

开始养护晃山前需要了解的7件事

1. 1Sunlight & Placement

   Kozan enjoys good sunlight, but strong direct sun or afternoon western light in midsummer can scorch its leaves. Place it in full sun during spring and autumn, and move it to partial shade or use a shade cloth to soften the light during the hottest summer months.

2. 2Watering Basics

   Satsuki azaleas have fine roots that are sensitive to drying out, so the basic rule is to water thoroughly once the soil surface feels dry. Be especially careful not to let the soil dry out during summer, when flower buds are forming, and water during the cooler morning or evening hours.

3. 3Choosing the Right Soil

   Kozan, like other satsuki azaleas, prefers soil that balances water retention with good drainage. A mix based mainly on kanuma soil is commonly used, since soil that drains poorly or dries out too quickly can damage the roots.

4. 4When to Repot

   Because satsuki roots are delicate, repotting is generally done around the time new shoots begin to emerge after flowering. Repot roughly once every few years, taking care not to disturb the root ball too aggressively.

5. 5Seasonal Care

   Kozan branches and buds readily, so pruning and pinching after flowering make it easy to maintain its shape over time. In winter, keeping the tree sheltered from frost and cold winds helps reduce stress on the plant.

6. 6What to Look for in a Tree

   Kozan has been cultivated for generations, and some specimens have been trained into notable bonsai over many years. Look for a tree with densely growing branches and healthy budding out to the tips, which makes ongoing care easier.

7. 7Flower Color & Blooming

   Kozan's small flowers range from soft brownish to pale pink, giving them a subtle, refined appearance. The depth of color can vary somewhat from year to year on the same tree, which is part of its charm.
