奧托納三脈 (Othonna triplinervia)的基本資料

栽培難度

適合新手

壽命

長壽命的小灌木（關於壽命的資料很少）

體型

高度約40厘米，莖幹粗度4厘米以上

澆水

生長期適度澆水

光照·擺放位置

在明亮的地方栽培。在接近自生地的較嚴酷環境中栽培可使植株更加緊湊。

澆水

有兩種澆水方法：一是按冬型植物栽培，秋春季供水；或根據其常綠特性全年適度供水。觀察葉片狀態，落葉跡象明顯時減少澆水。

休眠期管理

按冬型栽培時，春季葉片開始變黃時減少澆水，夏季保持乾燥環境讓植株休眠。

溫度·越冬

自生地為溫暖的崖地，幾乎不遭霜凍。冬季應避免霜凍。

用土·換盆

由於本種生長於岩壁裂隙，應使用排水性極佳的土壤進行種植。

關於奧托納三脈 (Othonna triplinervia)

Othonna triplinervia is a caudiciform shrub from South Africa's Eastern Cape, with a swollen succulent trunk, netted leaves, and bright yellow flowers. Beginner-friendly and prone to staying evergreen.

開始照料奧托納三脈 (Othonna triplinervia)前需要了解的7件事

1. 1Light and Airflow

   During the growing season, keep it outdoors in a bright, well-ventilated spot so the trunk develops a firm, compact shape. Intense midsummer sun can scorch the leaves, so light shade or partial cover in peak summer helps. In winter, move it indoors to a sunny window away from frost.

2. 2Water by Watching the Leaves

   Two approaches are described: watering from autumn to spring as a winter grower, or watering sparingly year-round, since it stays evergreen when water is available. Either way, watch the leaves and reduce watering when they start to drop. It grows in cliff crevices, so use a very free-draining mix.

3. 3Well-Draining Soil

   Use a fast-draining mix formulated for caudiciform plants, or blend akadama, pumice, and perlite. A coarse mix that lets excess moisture drain quickly helps prevent the succulent trunk and roots from taking up too much water.

4. 4Repotting Timing

   Spring to early summer, when growth picks up, is the best time to repot. Loosen the root ball, remove old soil, and trim away any damaged roots before planting in fresh mix. This is also a good opportunity to check root health, so consider repotting every few years.

5. 5Seasonal Care

   During the spring-to-autumn growing season, give it plenty of light and water to encourage growth. Unusually for Othonna, this species tends to hold onto its leaves, but growth slows in winter, so cut back on watering and protect it from cold and frost.

6. 6Choosing a Healthy Plant

   Look for a plant with a firm, well-swollen base, with a trunk diameter of around 4cm or more as a good benchmark. Leaves with good turgor and clearly visible netted veining are signs of healthy growth. Also check the trunk for any wounds or soft spots.

7. 7Easy for Beginners

   This species is considered beginner-friendly, and with basic attention to watering and placement, it's an easygoing caudiciform to grow long-term. As a small shrub reaching about 40cm tall, and unlike many Othonna species, it tends to stay evergreen, so you can enjoy its foliage year-round.

奧托納三脈 (Othonna triplinervia)的常見問題

Q.Is Othonna triplinervia suitable for beginners?

A.Yes, it's generally considered beginner-friendly. As long as you follow the basics of watering and placement, it's an approachable caudiciform for those new to the group.

Q.Does it lose its leaves in winter?

A.Unusually for the genus Othonna, this species tends to stay evergreen. That said, some leaf drop can still occur depending on growing conditions.

Q.How large does it grow?

A.It's a small shrub that reaches about 40cm in height, with a trunk that thickens to 4cm or more. It's long-lived and slowly bulks up its trunk over time.

Q.How often should I water it?

A.Two approaches are described: watering from autumn to spring as a winter grower, or watering sparingly all year. As a guide, reduce watering when the leaves start to drop. The succulent trunk stores water, so avoid overwatering.

Q.When and how often should I repot it?

A.There isn't much detailed information on repotting timing or frequency. When it becomes root-bound, repot into a very free-draining mix while the plant is in leaf and actively growing. It's also a good chance to check root health.
