We need help my wife and I we bought two jasmine plants from bents we have given them plenty room by putting them in very large pots.
But it is now over 3/4 years and we are disappointed at the growth of them,we were told they would grow so many inches per year ,they have not we erected an arch fro them to grow on either side , but nothing much, has anyone any ideas are we doing something wrong or what ,oh by the way we feed them as required still disappointed!
