劳伊石莲花

劳伊石莲花的基本数据

养护难度

适合中级者

寿命

多年生。生长缓慢

体型

莲座直径约15厘米

浇水

施肥宜稍多（这样叶片会变得肉厚圆润）

光照和放置位置

充分接受日光。光线不足时叶片可能萎蔫脱落。夏季需放在避雨、通风良好的明亮半阴处，冬季置于不受霜冻的阳光充足处或室内朝阳位置。

浇水

春秋型。3月至9月土壤干燥后适度浇水，避免从叶片上浇。高温多湿的夏季基本停止浇水，冬季置于凉爽通风处，保持相对干燥。

温度和越冬

根据海外资料能耐受至-3℃，国内图鉴以0℃作为不会枯死的最低温度参考。冬季管理特别需要注意。

肥料

施肥稍多会使叶片变得肉厚、矮小、圆润，形成形态优美的莲座。

繁殖方法

不易产生子株。由于容易自花受粉，建议在花后不剪掉花茎，让种子成熟后用播种法繁殖。叶插可用下层叶片进行，但成功率较低。

病虫害和注意事项

白粉一旦触碰就会脱落且不可复原。应避免接触叶片进行操作，换盆时需要托住根球进行。

关于劳伊石莲花

Echeveria laui is a species Echeveria from Oaxaca, Mexico, prized for its pure white rosette coated in thick farina. About 15 cm across and slow-growing, it suits intermediate growers. Learn the key points on placement and watering.

开始养护劳伊石莲花前需要了解的7件事

1. 1Keep Hands Off the Farina

   The farina on the leaves comes off when touched and leaves visible marks, and the bare patches are slow to recover. When moving the pot or repotting, hold the pot or the base of the plant, and avoid touching the leaves or the center of the rosette. This is a plant best enjoyed by looking rather than handling.

2. 2Bright, Airy Spot

   Grow it in a spot with good light and steady airflow. With too little light the leaves stretch and the rosette loosens, so choose a bright position. In the strongest midsummer sun, provide some shade to prevent leaf scorch.

3. 3Water at the Base

   Water trapped between the leaves can cause rot, and droplets also spoil the farina. Bring the spout close to the base of the plant and water the soil without wetting the leaves. A good rule is to water thoroughly once the soil has dried out completely, and how often that is will vary with the season and your conditions.

4. 4Fast-Draining Soil

   Use a fast-draining succulent and cactus mix and a breathable pot to help prevent root rot. Because the plant grows slowly, a light mix that dries out readily is a good match.

5. 5No Rush to Repot

   Since growth is slow, frequent repotting is unnecessary. When the roots fill the pot or the soil has broken down, move the plant to a pot one size larger during its growing season. Support it gently at the base so your fingers stay off the leaves.

6. 6Seasonal Care Tips

   As with most Echeveria, spring and autumn are the main growing seasons. Give it plenty of light then and water once the soil has dried. In summer, avoid heat and humidity, keep air moving and water sparingly. In winter, protect it from frost and freezing, and keep it bright and on the dry side.

7. 7Choosing a Healthy Plant

   Look for a plant whose farina is even across the whole rosette, with plump, thick leaves and a tight, well-formed shape. It is safest to avoid plants with darkened leaves or a wobbly base. When yours arrives, handle it by the pot and leave the leaves untouched.

劳伊石莲花的常见问题

Q.Can a beginner grow it?

A.It is rated for intermediate growers. It is easier once you are comfortable judging watering and light, so beginners may feel more confident after practicing with other Echeveria first.

Q.Will it die if the farina rubs off?

A.Losing some farina does not by itself kill the plant. The bare spots are slow to recover, though, so try to avoid touching the leaves.

Q.How big does it get?

A.The rosette reaches about 15 cm across. Growth is slow, so it takes time to see a change in size.

Q.How often should I water it?

A.Rather than following a fixed schedule, wait until the soil is completely dry, then water thoroughly at the base. Water less in summer and winter, and keep water off the leaves.

Q.Should I grow it indoors or outdoors?

A.Either works as long as the spot is bright and airy. Rain on the leaves can wash off the farina and cause damage, so outdoors choose a place sheltered from rain and protect the plant from frost in winter.
