I feel like I had a 'duh' moment. Makes complete sense now about the greenhouse, specifically the humidity slowing down the drying process. Thanks for the help!
@Philipwonel - Yes I need to definitely kick the watering habit! I was only drenching them once a week when they were indoors, but have read that is probably too much. It is going to be a learning process no doubt, just hope I don't take down too many of my succulents with me
@Baja_Costero - I am going to go to the hardware store and purchase some shade cloth. Don't know why I didn't think of that instead of the glass house. Might even get some plastic so that when it rains I can put it on top so they don't get drenched too much. Unfortunately it rains so much here in NZ that I don't think the succulents will be happy without a cover, even if I have good draining soil.
@Lauriebasler - Thanks for the welcome and watering tips Laurie. I too watched all the youtube clips, but because there are so many different techniques I got confused about what I should or shouldn't do. I think I will stick to a watering process similar to yours - minimal water when no roots, and then once roots form a bit more squirty bottle action.
All succulents are out of the greenhouse and back on all my windows sills! Here's hoping they recover!
