Hello all. I cant seem to get my potted plants on an East facing terrace to do well. I have a rosemary plant that was nursery bought and it doesn't seem well at all...slightly yellow leaves, wimpy looking ..its frustrating because I have a lot of rosemary in the garden (we inherited it when we bought our house). In particular, one plant that's growing wild next to my driveway in rock hard clay/sand soil that is lush and green and spectacular. What am I doing wrong.
