奧東納卡卡利奧伊德斯 (Othonna cacalioides)

奧東納卡卡利奧伊德斯 (Othonna cacalioides)的基本資料

栽培難度

適合高級者

壽命

生長極為緩慢，壽命長（壽命數據稀少）

體型

地表附近的小型種。塊根直徑9公分以上

澆水

生育期間澆水適量

日照與擺放位置

生育期秋至春間應放在光照充足的地方栽培。在接近自生地較為嚴苛的環境條件下栽培，植株會更加緊湊。

澆水

本種為冬型生長。秋季新葉開始萌動時開始澆水，生育期應待土壤乾燥後再澆水。

休眠期管理

春季葉片開始泛黃脫落時應減少澆水，夏季保持乾燥使植物進入休眠。休眠期過濕會導致塊根腐爛。

介質與換盆

本種生長於淺砂質岩縫中，應使用粗砂和輕石含量高、排水性極佳的介質。

病蟲害與注意事項

本種自生地極為狹小，屬易危物種，國際貿易需要許可。由於生長緩慢、栽培困難，選擇根系發達的國內實生株可減少栽培失敗的機率，同時減輕對野生種群的壓力。

關於奧東納卡卡利奧伊德斯 (Othonna cacalioides)

Othonna cacalioides is a tiny South African caudex succulent, forming a flat underground tuber with clusters of small heads at soil level. A slow-growing, winter-flowering species for experienced growers.

開始照料奧東納卡卡利奧伊德斯 (Othonna cacalioides)前需要了解的7件事

1. 1Sun and airflow

   During the autumn-to-spring growing season, keep the plant somewhere bright and well-ventilated, such as a rain-sheltered outdoor shelf. In midsummer, move it out of direct sun into bright shade while it rests.

2. 2Water on a winter-grower schedule

   Begin watering once new growth appears in autumn, and water regularly through winter and into spring. In summer, withhold water almost entirely to let the plant rest in dormancy.

3. 3Use fast-draining soil

   Use a mineral-heavy, fast-draining mix with plenty of akadama or pumice to keep the caudex from staying damp. Avoid soil rich in organic matter, which raises the risk of root rot.

4. 4Repot only every few years

   Because growth is so slow, frequent repotting isn't needed. Repot only once roots fill the pot, timing it to the start of the growing season and using a shallow container.

5. 5Winter cold protection

   Despite growing in winter, it isn't very cold-hardy, so bring it indoors to a sunny window during sharp cold spells. Never let it be exposed to frost or freezing.

6. 6Summer is dormancy

   As temperatures rise, the plant stops growing and enters dormancy. The leaves may look wilted, but this is a natural response — simply keep it in a cool, airy spot and let it rest.

7. 7Choose plants by caudex condition

   Look for a caudex that feels firm, with little scarring or wrinkling. Specimens that have reached 9cm or more in diameter have real presence, and since the number and arrangement of heads varies plant to plant, choosing one whose form you love is part of the fun.

奧東納卡卡利奧伊德斯 (Othonna cacalioides)的常見問題

Q.Can beginners grow this plant?

A.It's considered a species for experienced growers, since it grows very slowly and requires judgment about when to water. It's best attempted once you're already comfortable with succulent care.

Q.If it's a "winter grower," why is it cold-sensitive?

A."Winter grower" describes a cycle of summer dormancy and autumn-to-spring growth, not high cold tolerance. Even during the growing season, bring it indoors when temperatures drop sharply.

Q.How large does the caudex get?

A.The underground caudex is said to reach 9cm or more in diameter, with several short heads arranged almost flush with the soil surface. Since growth is extremely slow, reaching that size takes many years.

Q.The leaves wilted in summer — is it dying?

A.Wilting leaves in summer are usually a sign of dormancy, not a problem. Cut back on water and let it rest quietly in a cool, well-ventilated spot.

Q.What do the flowers look like?

A.It bears small yellow flowers toward the end of the growing season, as the leaves die back. The blooms are modest, but combined with its low, ground-hugging form they give the plant a distinctive appeal.
