How to divide and transplant daylilies<br>Choose the time of year you want to divide your daylilies. It is best to divide them in early spring before they begin their yearly growth or wait until late summer when flowering is done. Whenever you choose to divide the plants, they may not produce flowers the first summer, or may produce fewer flowers than normal.
You shouldn't water daylilies right away after dividing because too much water during a separation can cause them to go into shock.
