What are the growth habits of Sempervivum arachnoideum?

Common name of Sempervivum arachnoideum

Sempervivum arachnoideum is commonly known as spiderweb houseleek.

Habits of Sempervivum arachnoideum

Sempervivum arachnoideum is a succulent plant in the genus Sempervivum, family Crassulaceae, and summer is its vigorous growth period.

Sempervivum arachnoideum is native to Europe and likes a warm, dry, sunny environment. Its most suitable growth temperature is 18~22°C.

It is drought-tolerant and tolerates partial shade, and can also take full-day sunlight. It likes a relatively dry environment, so water less and keep the potting soil dry.

In home care, it is commonly propagated by sowing and cuttings. Its main pests and diseases include leaf spot disease and whiteflies.

Care tips for Sempervivum arachnoideum

Watering: During the growing period, keep the potting soil slightly moist. If the potting soil is too wet, the leaves will grow rapidly, affecting the ornamental effect. In winter, when the temperature is lower, it is better to keep the potting soil slightly dry. When watering, do not water directly into the center of Sempervivum arachnoideum, so as to avoid the web-like structure disappearing and affecting its appearance.

Fertilizing: Fertilize once a month, using diluted cake fertilizer or special organic fertilizer for succulents. When fertilizing, apply thin fertilizer frequently to avoid excessive fertilization, which can cause leggy leaf growth and plant aging.

Repotting: Repot Sempervivum arachnoideum once every two years, and replace the soil at the same time. Choose a potting soil made by evenly mixing leaf mold and coarse sand, and add a small amount of bone meal to it.

Propagation methods for Sempervivum arachnoideum

Sowing: Sow indoors in pots in spring. Evenly scatter the seeds in the soil, no need to cover with soil, and place a layer of quartz sand around them. Keep the temperature at 20~22°C, and they will germinate in 10~12 days after sowing. The seedlings grow slowly; after they grow into young plants, they can be divided into pots and replanted.

Cuttings: Take cuttings in spring and autumn. Cut off the small buds at the base of the leaf rosette, insert them into the soil, and they will root in 2~3 weeks; after another middle week, they can be transplanted into pots. Alternatively, break off a leaf rosette that has a rhizome and pot it directly.

Suggested planting combination: Fenestraria rhopalophylla.
