玉扇

玉扇的基本数据

养护难度

适合中级者

寿命

长期生长的多年生植物（寿命资料较少）

体型

无茎、叶片呈扇状排列的中型品种。窗口大小因克隆而异

浇水

在春季和秋季生长期，施用稀释的低氮肥料，用量少量

光照和养护位置

不需要强光，全年在明亮的半阴处养护。从阴暗处突然移到直射日光会引起叶烧伤，特别是夏季应保持凉爽的半阴环境。

浇水

春秋型植物，在春季(3-6月)和秋季(9-11月)生长。生长期间土壤表面干燥时充分浇水，炎热的夏季和寒冷的冬季减少浇水使其休眠。也可采用浸盆底部给水的方法。

温度和越冬

以最低5℃左右的温度越冬。如果土壤干燥，可耐受短期轻霜，但在有霜冻的地区应移入室内。

土壤和换盆

由于其生有粗长的收缩根，需使用深盆。采用排水良好的沙质砾石土壤种植。每年根部会有腐烂，需要经常换盆。

繁殖方法

可通过分株、叶插、根插和播种进行繁殖。最适时期为3-5月和9-10月。要保持选育品种的性状相同，应采用分株或叶插等营养繁殖方法。

病虫害和注意事项

容易根腐，应避免过湿。花上可能出现介壳虫或蚜虫，根部可能有根粉虱，常潮湿的土壤会导致蕈蚋幼虫伤害根部。

关于玉扇

Haworthia truncata has flat, blunt-cut leaves in two fan-shaped rows, tipped with translucent lined windows. A guide to its traits and care for intermediate growers.

开始养护玉扇前需要了解的7件事

1. 1Bright, part shade

   Strong direct sun can damage the windows at the leaf tips, so a bright spot in part shade, such as behind a sheer curtain, suits it best. If the light is too dim, the leaves stretch and the tidy fan shape tends to loosen.

2. 2Water after drying

   Let the soil dry out completely, then water until it runs out of the drainage hole. Constantly damp soil can damage the roots, so leave clear gaps between waterings. Leaves that begin to lose their firmness are a useful sign that the plant is ready for water.

3. 3Free-draining soil

   A free-draining mix made for succulents and cacti is the basic choice. Adding a generous amount of coarse grit, such as pumice, helps keep the roots from staying stuffy and wet.

4. 4Repotting and depth

   When the roots fill the pot, it is time to repot, roughly once every one to two years. Do it in spring or autumn while the plant is growing, and wait a few days before watering to reduce the risk of root damage. Set the plant so the leaf bases sit about level with the soil surface, and avoid planting too deep.

5. 5Summer and winter

   In the height of summer growth slows, so keep the plant somewhere cool with good airflow and water sparingly. In winter, bring it indoors to a bright spot where it will not freeze, and keep it on the dry side.

6. 6Choosing a plant

   Look for firm leaves and windows that keep their translucent clarity. Also check that the leaf bases are not darkened or mushy. Window size and pattern vary by clone, so it helps to compare photos and pick the look you like best.

7. 7Marks and pests

   Scratches and sunburn tend to remain visible on the windows, so avoid handling the leaves more than necessary. Poor airflow makes pests such as mealybugs more likely, so check the plant regularly, all the way down to the base.

玉扇的常见问题

Q.Can a beginner grow Haworthia truncata?

A.It is rated for intermediate growers because light and watering take some practice. Gaining experience with other succulents first is reassuring, but a beginner can still succeed by letting the soil dry out between waterings.

Q.Why do the windows turn cloudy or change color?

A.Common causes include sunburn from strong light and root damage from overwatering. Start by checking how bright the spot is and how often you water, then watch how the plant responds.

Q.How long does Haworthia truncata live?

A.It is a long-lived perennial, although reliable sources on its lifespan are limited. Preventing root damage and stuffy, wet conditions is the best way to keep it healthy for years.

Q.Why do window sizes differ between plants?

A.Haworthia truncata is a stemless, medium-sized species with leaves in a fan, and window size and pattern vary by clone. If you want a particular look, compare the photos on each listing carefully.

Q.Can I grow it on an indoor windowsill?

A.A bright windowsill behind a sheer curtain works well. Still air can leave the plant stuffy and damp, so open the window from time to time to keep the air moving.
