蛛丝长生草

蛛丝长生草的基本数据

养护难度

适合新手

寿命

多年生。开花的莲座在结实后枯死，由子株继续生长

体型

莲座直径约1-2厘米起。群生时形成直径30厘米以上的垫状株丛

浇水

在春秋两季生长期施用少量缓效肥料或液体肥料

日照和放置位置

除盛夏外，在室外光照充足的地方种植。由于不耐热，梅雨季至夏季应放在避雨、通风良好的半阴处越夏。从晚秋开始叶片变红。

浇水

春秋型，在春季（3-6月）和秋季（9-11月）生长。生长期当土壤表面干燥时充分浇水，梅雨季后至夏季休眠期减少浇水。过多的水分易导致腐烂，因此需要避免过量浇水。

温度和越冬

耐寒能力很强，据称至少可耐-12℃。然而，由于叶尖的蜘蛛丝状细毛易积聚雨水而腐烂，冬季应避免长期淋雨。

土壤和换盆

使用混合碎石、排水性良好的土壤。不喜欢肥沃的土壤。每2-3年在生长期前或初期进行一次换盆。

繁殖方法

通过分株或切取匍匐茎先端的子株进行扦插繁殖很容易。最适宜的时期是3-5月和9-10月。

病虫害和注意事项

由于开花的莲座会枯死，应及时清理花茎以促进子株生长。茎叶可能会出现介壳虫或蚜虫，根部可能出现根粉蚧。

关于蛛丝长生草

Cobweb houseleek (Makiginu) is a beginner-friendly Sempervivum whose small rosettes are joined by web-like white threads. Cold-hardy and native to European mountains, it grows from rosettes of 1 to 2 cm into mats over 30 cm wide. Learn the care basics and how to choose a plant.

开始养护蛛丝长生草前需要了解的7件事

1. 1Light and airflow

   Choose a bright, well-ventilated spot outdoors. With too little light the rosettes stretch out and lose their tight shape. A place sheltered from driving rain, such as under the eaves, makes care easier.

2. 2Water on the dry side

   Water thoroughly only after the soil has dried out completely, until it runs from the drainage hole. Water pooling between the leaves can cause damage, so pour at the base instead of over the top. Erring on the dry side is safer than overwatering.

3. 3Free-draining soil

   Use a fast-draining mix. Commercial succulent and cactus soil blended with pumice or sand keeps water from lingering around the roots. Because the roots are shallow, a shallow pot works well.

4. 4Watch for summer humidity

   Since it grows wild in high mountains, it is not at its best in the hot, muggy weather of the rainy season and summer. Move it to a bright, airy place out of the rain and water sparingly. Removing outer leaves that have been damaged by stuffy conditions helps keep the rest of the plant healthy.

5. 5Wintering outdoors

   It is very cold-hardy and can spend the winter outdoors. Growth slows in winter, so cut watering back even further. Keeping the pot under the eaves prevents the soil from staying soaked by rain or melting snow.

6. 6Repotting and dividing

   When offsets crowd the pot, it is time to repot or divide. Spring or autumn, when the weather is mild, is the best time; simply detach an offset from its parent and plant it to make a new one. A rosette that flowers dies after setting seed, so let the offsets carry the clump on.

7. 7Choosing a plant

   Look for tight rosettes with healthy leaf color and no melting or blackened outer leaves. The amount of white webbing varies with conditions and season, so do not judge a plant by webbing alone. A plant that already has offsets is also easier to keep renewing.

蛛丝长生草的常见问题

Q.Can a beginner grow cobweb houseleek?

A.Yes, it is considered beginner-friendly. Give it a bright, airy spot, a free-draining soil, and water on the dry side, and it is easy to keep. Just watch out for stuffy, humid weather in summer.

Q.Do I need to bring it indoors for winter?

A.It is very cold-hardy and can stay outdoors through winter. However, soil that stays wet from rain or melting snow can cause damage, so a spot sheltered from rain, such as under the eaves, is a safer choice.

Q.Is it my fault if a rosette dies after flowering?

A.No, this is normal. A cobweb houseleek rosette that flowers will die after setting seed. If offsets are growing beside it, they take over and keep the clump going.

Q.Why has the white webbing become sparse?

A.The amount of webbing changes with conditions, the plant's health, and the season. A weak plant from too little light or stuffy air may show less of it, so it is worth reviewing its position and ventilation.

Q.How large does it grow?

A.A single rosette starts at about 1 to 2 cm across. As offsets multiply, the clump can spread into a mat of 30 cm or more. A shallow, wide pot suits it well if you want to enjoy that spreading habit.
