My four o'clocks are not blooming. They are big and beautiful but not blooming. Can you tell me why?
4 O’clocks Not Blooming
Four o'clocks are often mid-summer bloomers. since I don't know where you are, it may be that it is not quite time for blooms there. You mention the foliage looks good, if this is the result of lots of nitrogen fertilizer, the plant may be directing energy into foliage instead of flowers. If so, stop fertilizing, keep them watered and blooms may soon appear.
