Remedy

For small patches, plants can be dug up in their entirety (be sure to get all roots and the small bulbils that break off to form new plants - you may need to sift through your soil to get these). Do not compost or put in your yard debris bin any below-ground parts of the plant (tubers and bulbils) as they can be spread this way. The leaves and flowers are ok to compost or put in yard debris. For larger patches, digging is impractical and can cause a lot of disturbance; herbicide application may have more success. * Lesser Celandine: National Park Service fact sheet *Lesser Celandine info from West Multnomah SWCD

Location

We have 10 acres on the lower McKenzie. An acre in lawn and we are noticing large patches of lesser celedine this spring. We dont spray, try to use manual methods but with the large areas of celedine reading spray is recommended. Want to do it correctly and the window is now per recommendations I am reading.

We also have tansey and poison hemlock in smaller areas in comparison.
