The flowering period for poppies varies by species and climate. Deadhead the poppies right after their petals drop. The longer you wait to remove the spent flower, the longer the plant’s energy goes into developing seeds. Save time deadheading masses of poppies by using hedge trimmers or a shearing tool.Can annuals bloom more than once?Annual plants are plants with a life cycle that lasts only one year.
