What are the growth advantages of Sempervivum arachnoideum?

Common names of Sempervivum arachnoideum

Juanjuan is commonly known as cobweb houseleek.

Habits of Sempervivum arachnoideum

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

Juanjuan is native to Europe and likes a warm, dry environment with plenty of sunlight. Its most suitable growth temperature is 18~22°C.

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

Home care commonly uses sowing and cuttings for propagation. The main pests and diseases are leaf spot and whitefly.

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 Juanjuan, so as to avoid the web-like material 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 leaves and plant aging.

Repotting: Repot Juanjuan once every two years, and replace the soil at the same time. Use a potting soil made by evenly mixing leaf mold and coarse sand, with a small amount of bone meal added.

Propagation methods of 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 the seeds will germinate in 10~12 days. The seedlings grow slowly, and 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 take root in 2~3 weeks. After about another week, they can be transplanted into pots. Alternatively, break off a leaf rosette with a root stem and pot it directly.

Suggested planting combination: Frithia pulchra.
