Daylilies love being divided....rule of thumb for them is 1st year they sleep...2nd year they creep..third year they leap...they dont require much at all in form of fertilization...and seem to thrive on neglect most of the time...I have over 150 colors and keep going back each year to the daylily farm to get more...flowers and fabric are my addiction and I am not willing to look for a 12 step program
