We live in an area abundant with magnolia. We moved into our current home 3 years ago but the house has been in the family forever. In the garden is an evergreen magnolia which has not flowered in the 15 years it has been there. The leaves are lush and green. It looks the picture of health. The deciduous magnolia in the front garden was covered in flowers. Any tips on encouraging it to flower? I have fed it and given it a stern talking to but to no avail.
