Tips for growing sempervivum arachnoideum
Sempervivum arachnoideum, more generally known as cobweb houseleeks, is a resilient and hardy succulent with delicate web-like foliage. This native of Central Asia, with its solid rosettes of semi-evergreen foliage, makes a stunning addition to any rock garden or xeriscape.
Growing Sempervivum arachnoideum is surprisingly easy – all it takes is a sunny spot and a little bit of patience. These plants prefer light, lime-rich, well-draining soil and good air circulation. When it comes to watering, the trick is to keep the soil evenly moist but not too wet; otherwise, the plant can rot.

Propagating Sempervivum arachnoideum is also fairly straightforward – simply separate a few baby rosettes from the parent plant and replant them in a new container. Pay special attention when replanting, as improper care can lead to root rot. Once you have planted the baby offshoots, all you need to do is water the soil to keep it moist and the plants should thrive.

Common problems with sempervivum arachnoideum
Sempervivum arachnoideum, commonly known as cobweb houseleek, is a type of succulent plant known for its distinct feathery foliage and hardy characteristics. This species hails from the very mountainous terrains of the Mediterranean, as well as Western and Central parts of Europe.
Thanks to its ability to withstand extreme climates, cobweb houseleek has become an increasingly popular choice for urban gardens and green spaces. However, with this increase in popularity comes its share of common problems. While typically quite resilient, these plants can suffer from insect pests and diseases such as powdery mildew, root rot, and aphids if not cared for properly.
It is important to make sure that the plant’s environment is conducive to its growth, and to address any health issues as soon as they arise. One of the most important tasks that gardeners must take care of with cobweb houseleek is to ensure it is planted in well-drained soil. These succulents prefer a neutral or slightly acidic soil with a pH of between 6 and
5, and they should not be overwatered or their leaves might turn yellow and eventually rot. Additionally, they should receive plenty of sunlight, with at least 6 hours of direct sunlight daily.
If these conditions are not all met, the cobweb houseleek could become prone to various diseases, so it is important for a gardener to pay close attention to the environment it is planted in. Finally, cobweb houseleek should be inspected regularly for signs of pests or diseases. The occasional aphid or mealy bug can be taken off with soapy water, but if the infestation is more serious, more drastic measures may be necessary.
Powdery mildew can easily be treated with some simple fungicides and root rot can be tackled with fertilizer and soil that drains more easily. Of course, if any of these conditions become overwhelming, it is always a good idea to consult with a professional.
