This year was so strange for my sunflowers – first of all, not a single one bloomed until August 18th. That is by very far the latest I’ve ever seen them wait. I’ve seen them bloom as early as 4th of July, and sometimes as late as the first week of August. But I’ve never seen it take this long.
Not only that, but they didn’t grow very tall. I planted “Mammoths” exclusively. But only a few grew taller than the fence, and most petered out at only 4 feet or so. I plan to have my soil tested this fall and make necessary improvements in fertilizers.
But – when everything did bloom, good night, it was gorgeous.
