With their cheery white petals, Shasta daisies are perennial flowers that grow well in zones 4-10. Despite their popularity and abundance, Shasta daisies can be fussy. They prefer full sun and with their shallow roots require frequent watering. They fare best over the winter in a bed with good drainage. A layer of wood chip mulch will help retain moisture. Some plants need staking to keep from falling over. Although clumps of Shasta daisies need to be divided every 2-3 years, this is best done in the spring. If cared for properly during the growing season, Shasta daisies will thrive and winterizing will be simple.
Cut back the dead stems to the base of the plant after the Shasta daisies are finished blooming.
Add a 2-inch layer of salt hay, straw or evergreen boughs to mulch the flower bed when the ground begins to freeze. Although more wood chips can be used, these materials provide more effective winter insulation.
Remove winter mulch from the flower bed in the early spring or around the time the ground can be worked.
