Hi, thanks a lot for your reply. It was 30°C and a couple of degrees lower at night. I read somewhere that they wilt from not being watered properly, could it be that they need water? I skipped watering them yesterday because I was out all day, and only watered it this morning.
The thing is am not sure, if I should water it less or more? Or is it the heat? Or is it gone for good now? The pot has drainage holes, I checked when I got them.
