Will ‘Stella d Oro’s re-bloom, and does deadheading improve re-blooming?
Yes and yes! When they (re-blooming daylilies) finish with the first flush of spring flowers, deadhead them (flower stalks and all), give them a light feeding and water well. Continue this and they will re-bloom again and again, but the re-bloom is never quite as colorful as the first flush of colors.
