瑠璃殿（Haworthiopsis limifolia）

瑠璃殿（Haworthiopsis limifolia）的基本資料

栽培難度

適合新手

壽命

多年生（壽命資料較少）

體型

蓮座直徑5～6公分（大型無性繁殖系可達12～15公分）

澆水

春季和秋季生長期施用緩效肥料或少量液體肥料

日照與放置位置

全年於明亮半蔭處栽培。即使直射光也不會枯萎，但生長會緩慢且葉色不佳。適度日曬會使株體轉紅且更為緊湊。

澆水

春季（3～6月）和秋季（9～11月）生長型。生長期表土乾燥後澆透水，夏季和冬季控水。

溫度與越冬

冬季在不受凍的明亮位置乾燥休眠。潮濕的介質受寒易導致根腐。

介質與換盆

使用排水性佳的介質，介質老化後於生長期前期或初期進行換盆。

繁殖方式

換盆時分株子株最為便利。亦可用葉插或播種繁殖。適期為3～5月和9～10月。

病蟲害與注意事項

花朵可能出現介殼蟲或蚜蟲，根部可能出現根粉蚧。介質長期潮濕易發生蕈蚋。

關於瑠璃殿（Haworthiopsis limifolia）

Ruriden (Fairy washboard): a beginner-friendly hard-leaved Haworthia with file-like white ridges and a pinwheel rosette 5 to 6 cm across.

開始照料瑠璃殿（Haworthiopsis limifolia）前需要了解的7件事

1. 1Bright window spot

   This hard-leaved Haworthia keeps a tight, compact rosette in bright light, while too little light makes the leaves stretch and the shape loosen. Strong direct sun can scorch the leaves, so light filtered through a sheer curtain is a good choice.

2. 2Water when dry

   In the spring and autumn growing seasons, wait until the soil is completely dry, then water thoroughly until it runs out of the drainage hole. Water can collect in the twisted center of the rosette and cause damage, so pour it onto the soil at the base of the plant.

3. 3Fast-draining soil

   A commercial succulent mix, or a blend based on pumice and akadama, drains quickly and suits this plant well. Roots are easily damaged when the soil stays wet for long, so choose a pot with drainage holes.

4. 4When to repot

   When the roots fill the pot, move the plant to a slightly larger one in spring or autumn, during the growing season. Every one to two years is a rough guide, but let the plant's condition decide. If offsets have formed, repotting is also a good time to separate them.

5. 5Summer heat care

   Growth slows in Japan's hot, humid summers, so move the plant to bright shade with good airflow and water sparingly. A closed-up room or a spot in direct sun can lead to rot from stuffy air or to leaf scorch.

6. 6Keep frost away

   Frost and freezing can damage the plant, so bring it indoors to a bright spot before the cold sets in. Growth slows in winter, so water less often and keep the soil on the dry side. Windowsills get cold at night, so keep an eye on them.

7. 7Choosing a plant

   Look for firm leaves with the white, file-like ridges clearly intact. Check that the base is not wobbly and that no leaves are blackened or mushy. A typical rosette is 5 to 6 cm across, and large clumps can reach 12 to 15 cm.

瑠璃殿（Haworthiopsis limifolia）的常見問題

Q.Can beginners grow Ruriden?

A.Yes, it is rated beginner-friendly. Keep it in a bright spot and water only once the soil has dried out. The most common mistakes are overwatering and leaving it in strong midsummer sun.

Q.How big does Ruriden get?

A.A rosette is typically 5 to 6 cm across, and large clumps can reach 12 to 15 cm. Repot during the growing season once the roots fill the pot.

Q.Can it be grown on an indoor windowsill?

A.Yes, as long as the windowsill is bright. Too little light makes the leaves stretch, so choose a place that gets light through a sheer curtain and make sure the air does not stagnate.

Q.What if the leaves shrivel or turn soft?

A.If the soil is bone dry, the plant may need water, so water it during the growing season and watch how it responds. If the leaves are soft while the soil is still damp, the roots may be damaged. Take the plant out of the pot, check the roots, and replant it in dry soil.

Q.How long does Ruriden live?

A.It is a perennial and can be grown year after year. However, reliable sources on its lifespan are scarce, so I can't give a specific number of years.
