A friend left me several Adeniums when he passed away. I repotted them in a well-draining mix of potting soil and perlite. They are outside in full sun in the summer months and in my garage during the winter (in Alabama). I fertilized them with Miracle grow in spring. They look healthy and the trunks have grown thicker, but they have not flowered in over 4 years. What am I doing wrong?
