I found the following info.:

Try as much to avoid overwatering as it could cause the roots to rot. Wait for the soil to dry up completely before watering your Senecio Angel Wing again. During winter when most of the growth hormones dormant, you need to cut back the watering intervals drastically. Keep the growing pot near the sunniest windowsill to help the topsoil dry up much faster.

Nature has designed succulents to survive dry for a long time.
You can bring it indoors for winter. They really hate being kept damp especially when combined with cold. In cold weather they need very little watering - probably once a fortnight or less depending on how warm the room is and let it dry out pretty well completely before watering again.. Under water rather than over water if in doubt. It will survive being dry but not being wet for long.
You can keep it growing over the winter if the room is warm or you can keep it pretty dry and have it in a cool place. The deadly combination is cold and wet.

Shirleytulip - apologies - just noticed I've more or less duplicated what you said. At least we agree!

Sue, no need to apologise! We are singing off the same song sheet after all.
