FAQ
Can succulents survive 40 degree weather?
Succulents are well-equipped to endure both hot and cold environments. They can survive in temperatures as low as 40°F, just like the desert which can experience cold nights.
Do you cut back Sempervivum?
Sempervivum species do not need to be trimmed, however it is wise to snip off any spent flower spikes and gently discard any dried, wilted or dead leaves.
What is the silver thaw effect?
Why is my Sempervivum growing tall?
This odd growth pattern is what accelerates the plant’s growth when there is not enough sunlight.
Is Sempervivum frost hardy?
Sempervivums are able to tolerate temperatures as low as -30 degrees Fahrenheit (Hardiness Zone 4 – Zone 9), which may cause their rosettes to shut up more tightly and their colors to become darker (some even turning a deep red). This is a natural protective response to the cold climate.
