Caring For Sempervivum Arachnoideum
1) Light: You have to acclimate the Sempervivum arachnoideum to full sun if you want to avoid sunburn. Start by exposing the plant to the morning sun for 1-2 hours daily. After about a month, you can introduce the plant to the afternoon sun for about three hours daily
2) Frost Tolerance: One of the great features of the Sempervivum arachnoideum is that it can withstand frostbite and freezing temperatures that are below 15 degrees Fahrenheit
3) Soil: The soil you grow your Cobweb Houseleeks in determines how well they will be able to resist pests and diseases. Sempervivum arachnoideum grows best in sandy soil with good drainage. Ensure the soil pH is somewhere between very acidic and slightly alkaline (6-8)
4) Watering: You have to water the succulents at least once a week. It is best to water before sunrise or just after sunset to prevent the evaporation of moisture.
