大盃的基本資料

栽培難度

適合新手

壽命

壽命長，多有古樹栽培

體型

庭木約0.5～1m（盆栽從小品到大品）

澆水

肥料（4月、花後的6月、9～10月）

光照・擺放位置

喜光，但夏日強光容易造成葉燒和根傷。幼樹宜充分日照，樹形維持階段則放在半陰處。要確保通風。

澆水

喜潮濕，但根系細弱怕過濕。春季每天1～2次，夏季2～3次，冬季2～3天1次為目安。避免在高溫的白天澆水。

溫度・越冬

有耐寒性，但怕冬季寒風。要在屋簷下等處保護，防止盆土結凍。

基質・翻盆

以鹿沼土為主的酸性粗質基質。翻盆在花後立即進行（6月）或秋季（9月下旬～10月上旬）。秋季翻盆的株體冬季保護要謹慎。

肥料

新芽硬化期4月左右、花後的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・塑形

耐修剪，在任何位置切割都會發芽。觀花株在花後6月中旬（關東以西至7月初）進行修剪，粗幹培育的重剪在開花前4～5月進行。

病蟲害・注意事項

病蟲害較多的樹種。易發生軍配蟲、紅蜘蛛、蚜蟲、薊馬，生長期需定期防除。

關於大盃

Osakazuki is a classic Satsuki azalea with abundant deep pink-purple blooms. Sturdy, prune-tolerant, and beginner-friendly, it's known for reddish bark and long-lived old specimens.

開始照料大盃前需要了解的7件事

1. 1Light & Airflow

   Osakazuki thrives in bright, sunny spots outdoors and flowers best with plenty of light. In midsummer, filtering the light with partial shade or a shade cloth helps prevent leaf scorch, and good air circulation helps keep pests and disease at bay.

2. 2Watering Basics

   Water thoroughly, letting it run from the drainage holes, once the soil surface has dried out. Satsuki azaleas have fine roots that are sensitive to drying out, so pay extra attention during the flowering season and in midsummer; in winter, the soil dries more slowly, so water less often.

3. 3Choosing Soil

   Unlike many other trees, Satsuki azaleas do best in a soil mix formulated specifically for them. Look for a slightly acidic blend that balances drainage and moisture retention, which keeps the roots healthy. A commercial Satsuki-specific potting mix is a reliable, low-risk choice.

4. 4When to Repot

   The best time to repot is after flowering, around the start of the rainy season. Repotting into fresh soil, without disturbing the root ball too drastically, helps prevent root-bound growth and keeps the plant healthy; doing this roughly every few years is a good rule of thumb.

5. 5Pruning & Shaping

   Osakazuki tolerates pruning well, making it a great choice for shaping. Deadheading and light trimming right after flowering won't interfere with next year's flower buds, and the variety also handles harder pruning reasonably well if timed carefully.

6. 6Seasonal Care

   Osakazuki blooms from spring into early summer, then enters a period of new growth. Keep an eye on strong summer sun and dryness, as well as winter frost and cold winds. Adjusting its placement with the seasons helps keep the plant healthy over the long term.

7. 7Choosing a Plant

   Because Osakazuki is often grown as a long-lived old tree, individual specimens can develop distinctive trunks and branch shapes. Look for a plant with deep leaf color and healthy foliage all the way to the branch tips, which tends to indicate stable future growth, comparing trunk shape and bark tone is part of the fun of choosing one.
