tink3472,
Thanks so much for posting such experienced based info. You cleared up something for me that was so obvious, yet I had managed to over look it. The first thing I would need in order to establish peak bloom time would be a written list of all my daylily varieties and the total number of them.
If peak bloom is determined by when 80 per cent of the daylilies in the garden are in bloom, then I would have to know in advance exactly how many I had to start with, so obvious!
