Keep the container holding your African daisies in a spot that gets full sun. If your daisies are planted in the garden, select a site that gets at least 8 hours of daily sunlight.
Water frequently enough to keep the soil moist to the touch. Do not let the daisies dry out between waterings.
Apply a water-soluble fertilizer to the soil around the daisies once a week during the flowering season. Follow package directions for application instructions.
Use garden shears to cut off flowers as they begin to wilt and fade. This is a process known as deadheading and it will encourage the plants to produce more flowers throughout the season.
