Do pansies need a lot of water?
Watering: Consistent moisture keeps pansy blossoms soft and supple, but roots won’t tolerate soggy soil. Water pansies regularly through the growing season, but allow soil to dry slightly between waterings. The drier soil conditions also help pansies harden off and tolerate cold.
Pansies perform best in cooler weather, and are therefore usually planted in spring or fall. They like rich, well-drained soil high in organic matter, and full sun or partial shade.
