Shasta daisies (Leucanthemum) are what many imagine when they think of daisies. The white radiating petals of each flower surround a bright yellow eye. The daisies grow on tall 1- to 3-foot stems. The shorter growing varieties work well in both indoor and outdoor pots. When grown indoors or in subtropical climates, the Shasta daisy provides year-round blooms. It grows as a herbaceous perennial in areas that experience frost, dying back each fall and returning in spring unless the pots are brought indoors for winter.
Plant the Shasta daisy plant in a 10- to 12-inch diameter pot. Set the plant in the pot at the same depth it was growing at in its nursery container.
Set the pot in an area that receives full sunlight. Outdoor pots tolerate light morning shading. Place indoor pots near a south-facing window or other brightly lit location to ensure best flowering.
Water the pots when the top inch of soil dries. Outdoor daisies may require one to two waterings a day depending on the heat and how quickly the soil in the pots dries. Indoor plants typically need watering once or twice a week.
Fertilize the daisies once monthly when the plants are actively growing with a soluble fertilizer at the rate recommended on the label. Bedding plants rarely require fertilization, but potted daisies depend on fertilization for all their nutritional needs.
Cut off the old flowers with shears when they begin to wilt. Remove the flower stem above the top set of leaves on the stem. Flower removal, called deadheading, encourages the Shasta daisy to send up more flowering stems.
Things You Will Need
