I feel your pain! I'm currently mid house move and have hoyas shoved everywhere around the new house. I left some on a window sill which I didn't realise gets full sun during the day and against cold glass overnight.... No obvious damage that I can see but it's early days.....

Fun fact, I've been transporting my hoyas on my lap in the car (I'm not driving) in small batches so I don't damage any. So far, so good!

Oh geez, good luck with the move! Good thing you were able to catch it early on though.

I left my Chelsea out in the sun last year accidently and it bleached the outside leaves horribly! I took cuttings of the unbleached vines and rooted them to start over. I felt so bad for forgetting about it! :-(

It's such a horrible feeling. I was talking to a friend about it, and I likened it to dropping a puppy. Makes me sad. But luckily the plants will be okay (I hope). XD
