Sempervivum heuffelii ‘Lemon Sky’ is easily propagated, but is done a little differently than other Sempervivums.

Using a sterile knife or sharp pair of scissors, separate clumps to be propagated from main plant cluster. You’ll want to get some of the roots with the stem if at all possible. This will help the plant root faster.

Allow cuttings to callous over for several days before replanting in either the ground or well-draining succulent soil.
