My flowering gum buds do not open
My flowering gum buds are not opening. They appear to have a rot like appearance and some split down the side rather than the cap coming off and flowering. We propagated it from seed collected from gum nuts 2 years ago

I'm not sure of your location, but the most information that I can find is that this could be caused by excess heat and humidity.
Both of these weather conditions would be out of your control.
