Sue - Peak bloom season here for me was May this year. I had later blooms in June and a few to the middle of July (I believe that those were late bloomers or a few re-bloom). I can't remember if I had anything blooming in August or September. Sorry, but my life this year has been pretty stressful (work and my sister dealing with cancer just to name a few things) so I neglected to write blooming times down.
I alternate fertilizing with Miracle-Gro (liquid), time-released Osmocote, and milorganite. I also use pine fines and alfalfa spread around in the raised beds to attract earth worms. I water regularly several times a week.
