Answer: Daylilies usually bloom for a week or two with each bloom lasting only a day, so for extended bloom you need to plant several varieties or possibly a rebloomer which will bloom cyclically a few times during the summer. For longest display, the plants need to be well watered so that the soil stays evenly moist but not sopping wet. Rebloomers also need a rich soil. With new plants, the shock of transplanting and going through the retail process can reduce their bloom period; often they are set out for sale while in full bloom so this means they are nearly finished by the time you bring them home. Look for a longer display next summer!
