I have been growing Sempervivum all summer in small plastic pots. The original plants are now fading away - and I think I'm right to assume that as annuals they are now spent forces?
But the baby plants have grown as offsets. What should I do to propagate the offsets? Some appar to have broken off the parent plants themselves. Can the others be snipped off and repotted? If I do this now, will they last through autumn and winter outside, or should they be brought in?
When is the right time to divide and propagate Sempervivums, and how best should it be done?
