Hi! I recently got this spotted begonia and after 3 days of it being in its new home it started dropping healthy leaves. The soil is moist but not wet, it’s next to a humidifier, about 2 feet away for a south west facing window, and temps are 65-75 degrees. Does anyone know what could be causing this? My best guess is shock to it new environment. I’m attempting to propagate the fallen leaves. Is that possible with begonia leaves?
