Controlling Invasive Daylilies (Ditch Lilies) in a Mixed Border

Aggressive orange daylilies (Hemerocallis fulva) spread by rhizomes and can choke out neighboring plants.

Management Strategy

• Dig repeatedly—remove every rhizome piece you find.
• Plant desired perennials/annuals in the cleared spaces.
• Pull new daylily shoots as soon as they appear.
• Persistence wins; they will eventually exhaust their energy reserves.

Daylilies still bloom while spreading; flowering isn’t sacrificed for reproduction. No herbicide needed—just diligence.
