日轮玉

日轮玉的基本数据

养护难度

适合新手

寿命

多年生（寿命资料较少）

体型

单株长25～55毫米，宽20～40毫米。花径最大52毫米

适宜温度

8〜25℃

浇水

在秋至春的生育期施用少量缓释肥料或液体肥料

光照·放置位置

在避雨、光照充足的地方栽培。要使植株着色良好需要充分的光照。梅雨结束后至夏季在通风良好的半阴处休眠。

浇水

冬型种。从花期结束到老叶完全被新叶取代期间应少浇水。秋季变凉后重新开始浇水，生育期当土壤干燥时浇透。6～9月休眠期要控制浇水，保持干燥。

温度·越冬

冬季最低温度不低于3℃可使植株保持良好状态（植株不枯死的参考温度为0～3℃）。轻微霜冻很少导致植株枯死，但严寒期应移入室内或做好防寒措施。

土壤·换盆

由于植株具有牛蒡状的直根，应在深度较深、排水良好的土壤中种植。无需频繁换盆，仅当生育迟缓或花盆变得狭窄时，在10～11月进行换盆。

繁殖方法

可通过播种（10～11月）或分株繁殖。分株生根需要较长时间，应尽早进行。

病虫害·注意事项

花蕾和花易受蚧壳虫和蚜虫危害，根部易感染根粉蚧，花瓣易被蛞蝓啃食，叶片易被夜蛾幼虫取食。凋谢的花朵应及时用手指去除，以防腐烂。

关于日轮玉

Lithops aucampiae: a large, beginner-friendly living stone with a net-patterned reddish-brown top and big yellow flowers. Traits and care tips.

开始养护日轮玉前需要了解的7件事

1. 1Sun and airflow

   Nichirin-gyoku wants plenty of direct light. With too little, it stretches out and the net pattern on the top surface fades, so give it a bright spot sheltered from rain outdoors, or a sunny windowsill indoors. Good airflow also helps prevent stuffy, damp conditions.

2. 2Water mainly in autumn

   Watering centers on autumn, when the plant is actively growing. Wait until the soil is completely dry, then water thoroughly and let it dry out again before the next watering. It is fairly forgiving of watering mistakes, but avoid keeping the soil constantly damp.

3. 3Hold water while shedding

   Lithops shed their old leaves as a new pair grows from inside, mostly from winter into spring. The new leaves draw moisture from the old ones, so don't water until the old pair has shriveled to a papery skin. Watering during this stage can harm the plant, so be patient.

4. 4Keep it drier in summer

   Growth slows in hot weather, so cut back on watering and let the plant rest. Strong sun combined with damp heat can lead to rot, so a bright spot with good airflow is safer. When cooler weather returns and the plant stirs, resume watering gradually.

5. 5Choose a fast-draining soil

   Drainage is the top priority. Mix coarse grit such as pumice or sand generously into a commercial succulent mix so the roots dry quickly. Because the roots grow deep, a slightly deeper pot works well.

6. 6Repot only when crowded

   Frequent repotting isn't necessary; do it when the plant has multiplied and filled the pot. Early autumn, as growth resumes, is a good time, and it helps to hold back water for a while afterward to protect the roots. Avoid disturbing a plant that is in the middle of shedding.

7. 7Choosing a healthy plant

   Look for a firm top surface with no wrinkles, dark spots, or damage around the fissure. A clear dark brown net pattern on the reddish-brown ground is a good sign. Each head should measure roughly 25 to 55 mm long and 20 to 40 mm wide, so check the listing for the number of heads and the condition of each one.

日轮玉的常见问题

Q.Can beginners grow Lithops aucampiae?

A.Yes, it is rated as beginner-friendly. It is a hardy, widely grown species that is relatively forgiving of watering mistakes, but you should still water in autumn and hold back during shedding and in summer.

Q.When does it flower, and what are the flowers like?

A.It produces large, bright yellow flowers up to 52 mm across. Blooming is mainly in autumn, and plants grown in a sunny spot are more likely to flower well.

Q.Can I grow it on an indoor windowsill?

A.Yes, if the windowsill is sunny. Too little light makes the plant stretch and the pattern fade, so choose the brightest spot you have and make sure the air doesn't stagnate.

Q.The old leaves are shriveling. Is it dying?

A.This is normal shedding: the new pair of leaves uses the moisture stored in the old pair, so the old leaves shrink. Hold back water until they have become a papery skin, then return to regular care once shedding is finished.

Q.How many years can I keep it?

A.It is a perennial that grows by shedding its old leaves each year. However, there is little documentation on its lifespan, so a specific number of years can't be given. With care suited to its needs, it can be enjoyed for a long time.
