白馬城的基本資料

栽培難度

適合新手

壽命

長壽多年生植物（壽命資料較少）

體型

野生環境下高度1～2公尺，塊莖直徑可達1公尺。人工栽培下約1公尺高

澆水

生育期間適量施肥

光照與擺放位置

由於原生地生長在向陽的岩場，生育期應在直射日光充足的地方栽培。

澆水

夏季生長期間土壤乾燥時澆水。冬季落葉休眠，葉片脫落期間完全停止澆水。

休眠期管理

冬季提供略涼爽的休眠環境據稱能改善開花。春季新芽萌動時恢復澆水。

溫度與越冬

冬季停止澆水，在不受霜凍的地方越冬。

介質與換盆

使用排水良好的介質，在生育期初期進行換盆。

病害蟲·注意事項

象牙宮屬植物樹液具毒性，尖刺銳利。進行換盆或移動時應戴厚手套或用數層報紙包裹莖幹。

關於白馬城

Pachypodium saundersii (Hakubajo) is a southern African caudiciform plant with a rounded, swollen caudex, spiny branches, and large purple-tinged white autumn flowers. Relatively easy to grow and fast-growing, it suits beginners.

開始照料白馬城前需要了解的7件事

1. 1Choosing a Bright Spot

   This plant thrives in direct sunlight, so keep it somewhere it gets strong light from spring through autumn when grown outdoors. Avoid intense west-facing summer sun and low-light indoor spots, both of which can weaken growth. Good airflow also helps keep the plant healthy.

2. 2Watering Through the Seasons

   During the growing season from spring to autumn, water thoroughly once the soil surface dries out. As temperatures drop in autumn, gradually space out watering, and during winter dormancy keep it on the dry side—watering only enough to prevent the caudex from wrinkling—to avoid root rot.

3. 3Well-Draining Soil

   Since this plant dislikes staying wet, well-draining soil is essential. Mixing pumice or perlite into a standard succulent or cactus potting mix improves both aeration and drainage.

4. 4Repotting Timing

   Repot in spring to early summer, when rising temperatures bring active growth. Avoid breaking up the root ball too much, trim away any damaged roots, and move up to a slightly larger pot to support healthy caudex development.

5. 5Winter Care

   This plant is sensitive to cold, so move it to a bright indoor spot, such as a sunny windowsill, once temperatures start to drop. Keeping it on the dry side through winter lets it rest properly and supports strong growth the following season.

6. 6Selecting a Healthy Plant

   Look for a plant with a firm, well-rounded caudex and no major scars or dents on the surface. Balanced branch growth and healthy, densely packed spines are signs of a plant that is growing well.

7. 7Handle the Spines with Care

   The branches are covered in dense spines, so wear thick gloves when repotting or handling the plant. Keep it out of reach of small children and pets to avoid accidental contact.

白馬城的常見問題

Q.What temperature should I bring it indoors for winter?

A.There's no strict threshold, but since this plant is sensitive to cold, it's best to move it to a bright indoor spot once temperatures start dropping. Keep it on the dry side through winter so it can rest.

Q.Does it flower every year?

A.Once the plant is mature enough, it typically produces large white flowers tinged with purple in autumn. Good light and overall growing conditions help make blooming more consistent.

Q.Can I grow it indoors only?

A.It can be grown indoors near a bright window, but growth tends to be slower than with direct outdoor sunlight. Giving it outdoor sun during the warmer months when possible is beneficial.

Q.How large does the caudex get?

A.In the wild the caudex can reach about 1 meter across, and the plant becomes a shrub 1 to 2 meters tall. Size and growth rate in cultivation vary with conditions.

Q.Is it suitable for beginners?

A.This species is considered beginner-friendly and grows relatively quickly. With well-draining soil, adequate light, and a clear wet-dry watering rhythm, it's an approachable choice for first-time caudiciform growers.
