Where are you located Rina? I see we are in the same zone but my succulents have been outside since March. Interesting how much the weather can still vary even when you're in the same zone.

I am in Ontario, Canada, about 1hr north of Toronto. While we had some very nice and warm days, many nights got still cold. The worst was the wind. I had plants outside, but often had to bring them in (kept them in enclosed breezway). I am out of the city limits, open 'country', not much to protect from the cold winds. There is no way for them to be outside in March. Hostas outside didn't start growing until end of April...

Very good call in covering up your succulents! West of Toronto we got an incredible amount of rain last night and today. Not sure if it helps any, but I have a temperature monitor outside with my plants and this is the graph from May 28th to June 9th.

The temperature swings between the days and nights are pretty wild (for us at least):

Wow, that's a lot of work Rina!
