晃山的基本資料

栽培難度

適合中級者

壽命

作為品種的壽命資料稀少（多為銘木品種）

體型

盆栽可製作為小品〜大品

澆水

肥料（4月、花後6月、9〜10月）

日照與放置場所

喜歡日照，但夏日直射光會導致葉燒和根傷。幼樹應充分日曬，樹形維持階段則置於半陰處。確保通風

澆水

喜歡溼度但根細且怕過溼。春季每天1〜2次，夏季2〜3次，冬季2〜3天1次為目標。避免在高溫的白天澆水

溫度與越冬

有耐寒性但怕冬季寒風。在簷下等處保護，使盆土不結凍

用土與換盆

以鹿沼土為主的酸性粗質用土。換盆時間為花後立即進行（6月）或秋季（9月下旬〜10月上旬）。秋季換盆的株在冬季保護時需慎重

肥料

新芽固定的4月左右、花後6月、9〜10月每月1次固形肥料。肥料不足會導致枝條枯死

修剪與整姿

花芽在7〜8月中旬形成，故芽摘和修剪應在花後6月內（關東以西可至7月初）完成。鐵絲調整在4月和9〜10月進行

病蟲害與注意事項

該樹種特別容易染病蟲害。易遭受軍配蟲、蜘蛛蟎、蚜蟲、薊馬等危害，生長期需定期防治

關於晃山

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.

開始照料晃山前需要了解的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.
