Overall: I also had six oleanders which I repotted into very large pots. The advert stated that they needed little or no attention, winter tollerant down to minus 10. This was three years ago very green leaves,about 3ft tall but no flowers. One or two of the leaf ends are now going brown.
During the summer it was fed on a well known water based compost. During the winter it was put into my cold greenhouse.Still hasnt flowered ....any advice
