关于麻风树（Jatropha cathartica）

Jatropha cathartica (Nishiki-sango) is a spurge-family caudex plant with a pale, globular caudex and lobed gray-green leaves, bearing pink to scarlet-red blooms; a beginner-friendly, long-lived perennial.

开始养护麻风树（Jatropha cathartica）前需要了解的7件事

1. 1Sunlight & Placement

   Jatropha cathartica thrives with plenty of light, so keep it in the brightest spot you can offer, indoors or out. In peak summer, harsh direct sun can scorch the leaves, so shift it to filtered light or a well-ventilated, partly shaded spot during the hottest stretch.

2. 2Watering Basics

   Because the caudex stores water, let the soil surface dry out before watering thoroughly. Space out waterings when growth slows, and make sure the pot drains well to avoid root rot.

3. 3Choosing Soil

   Good drainage matters more than anything, so a succulent or caudex-specific soil mix is the easiest choice. Avoid using plain garden soil on its own, since its high water retention raises the risk of root rot.

4. 4When to Repot

   Repot once roots fill the container, ideally during the active growing season, moving up to a slightly larger pot. Gently remove old soil from the roots and trim away any damaged sections before replanting in fresh mix.

5. 5Seasonal Care

   Cut back on watering and let the plant rest when growth slows down, which reduces stress on the plant. As temperatures drop, move it somewhere sheltered from cold and sudden temperature swings.

6. 6Enjoying the Blooms

   During the growing season it produces a steady succession of small pink to scarlet-red flowers, and consistent light plus steady care is the key to good flowering. No special aftercare is needed once blooms fade — just keep up regular watering and sun exposure.

7. 7Picking a Good Plant

   Look for a plant with a firm, plump caudex free of scars or soft spots, which makes ongoing care easier. Check the leaves for unusual discoloration or wilting before you buy.
