Lesser Celandine and herbicides #926632

Asked March 24, 2026, 9:29 AM EDT

Hello, I am dealing with some lesser celandine issues in my yard. As I understand it, I could direct apply glyphosate to the lesser celandine to help control it. I don't think glyphosate remains active once in soil, but I wanted to reach out. Thanks!

Greetings, 

I have an article to share regarding Lesser Celandine from our Buckeye Yard and Garden Line here: https://bygl.osu.edu/node/2110

For glyphosate, I recommend you read, understand, and follow the product label to learn about persistence as that product comes in may different preparations. 

Thanks, 

Tim

Hello Tim,

Thanks for this information and article; it’s very helpful.

We have two large, healthy and mature oaks—a red and a white, I’m nervous about applying any herbicides to the lesser celandine that may damage them but it’s looking like it may get to dense mats if we don’t take care of it now. I used to have May Apple under the white oak, but I’m afraid we may lose that too.

I could always go to my native plant nursery to replace the May Apple but I don’t want to harm the oak.

Would the label instructions have information that pertains to what could happen to an oak if it’s sprayed too close?

Greetings, 

The label may or may not have that guidance.  If it does not, I recommend contacting the company using the phone number for their technical support on the package. 

Thanks, 

Tim
