Hello Gardening stackexchange!
We bought a few cacti and aloe vera last year, which live in pots. We took them inside the house at the start of the past autumn, when the temperatures were starting to get below about 7°C. The question is: when is it safe to put the cacti and aloe vera outside again? It is a rather cold spring here in Switzerland, with night temperatures still reaching 0-3°C, but daytime temperatures up to 15°C. Is there a clear advice that we can follow?
