Sylvia,
It is indeed the tradition in Japanese haiku to have one line for season or time-of-day reference. However, I have no issue whatsoever with breaking with the tradition here. I recently bought another haiku book, The Essential Haiku, edited by Robert Hass. It contains work by Basho, Buson (my favourite) and Issa. I recommend it highly.
