I planted Stella D’Oro lilies so that I would have constant bloom all summer long, since this is what they are supposed to do. However, mine bloom for about a month and then stop entirely. They then form large, green pods. Should I be removing these pods? Also, any tips on how to extend the blooming period?
First of all, you need to be aware that Stella D’Oro is not a continued bloomer, but rather a repeat bloomer. This means that it should bloom again for you later in the season, but not continuously all season long.
As far as general culture and routine care are concerned, removing the young seed pods should allow the plant more energy to develop new flowers rather than seeds. Also, for the greatest number of flowers, daylilies need to be fed in early spring and again in summer with a balanced fertilizer at the recommended rate. Although daylilies thrive in sun or shade, they bloom the best if they are in sunlight at least half the day.
Finally, to maintain vigor and flower size, daylilies should be divided every three to five years. You can do this anytime, but you would probably want to wait until plants go dormant in the fall.
