Protecting succulents from light frost over winter
Based in Gawler, on the outskirts of Adelaide and was wondering what steps I needed to take to protect my succulents from frosts. I was speaking to a grower today who indicated that I would need something to protect a lot of the plants (aeoniums, echeveria etc) during winter. She was talking about a thick plastic green house like set up, but as I've fallen down a rabbit hole of green house set ups, humidity and lack of airflow seem to be a potential issue if we go down that route. We don't get a ton of 0 degrees or slightly below nights, but we do get a few. We have a back veranda that doesn't get a lot of sun and a massive undercover area that does get some light with polycarbonate roofing that has solid and transparent panels, so could move them there, or build something purpose built. If anyone has any suggestions, it'd be much appreciated.
