Every year, I buy stocks and try to grow them. And, every year, they just sit there, don't bloom and get very straggly. I know they're a cool weather annual, and I think that I probably have them in too much sun. This year, I started them from seed early, so they're decent sized now. I planted them where they get sun until about noon. What else can I do to improve my chances of having them do well? Are there certain varieties that are easier than others to grow? I just have to have them, the fragrance is so wonderful! Any tips would be very much appreciated.
