The
orange daylily is a challenging plant to remove, as it spreads freely and has strong roots. Removing the seedlings before they get a chance to spread is ideal, but the plant will still have to be pulled out by the roots as it can come back from any small section of root left behind. Plants and roots should be placed in a plastic bag for proper disposal. Mowing the
orange daylily and smothering it with thick layers of mulch can also be effective. The plant will have a hard time emerging, but continued vigilance is necessary to be sure the plant does not break through. As a last resort, systemic herbicides can be used. However, herbicides can also kill other plants around if spread accidentally. If
orange daylily persists after two weeks, carefully apply a second round of the weed killer.
