Stella DOro Day Lillies


Question
QUESTION: I have lovely blooms in early summer but I don't get any more blooms after that.  I deadhead the old blooms.

ANSWER: Hi Lynn,
Thanx for your question.  Depending upon your zone the Stella D'Oros will bloom profusely for a while then take a brief rest before reblooming again in the late summer as long as you are removing all of the seed pods.  Sometimes, if you leave the seed pods on too long,the plant thinks it has reproduced itself and then starts preparing for dormancy and winter and in this case, it will not rebloom.  I hope this helps.

QUESTION: Right now the leaves don't seem to stand up as they used to.  They are lying almost flat on the ground.  I am in zone 5-10.  I try to water them frequently.  I have had these same daylillis for about 12 years.  Do some of the newer varieties boom moe profusely.  I don't really care about the color.  Is there another type of daylillie that would perform better?  Thanks,  Lynn

Answer
Hi Lynn,
Thanx for the additional information.  You may have a grubs or moles eating the rhizomes.  Daylilies are pretty tough and drought usually doesn't do much to them.  Check the leaves for signs of discoloring or for blisters or spots that might be a symptom of daylily rust which has recently been established in the U.S. from Asia.  The stella d'oro is known for profuse blooming and reblooms.  By late August they are pretty much done although you should have gotten some spotting reblooming.  Your daylilies are dying or at least declining due to an underground pest such as grumbs or moles or it has some kind of disease.  Did you check the crowns for signs of rot?  There is a fungus that attacks daylilies at the crown and causes rot.  Have you check for aphids (tiny insects green, yellow, brown or black) that suck juices out of the leaves. Let me know what you find out.
Tom
