Q.Hairy Bittercress Eradication

Zone 08822 Hunterdon County NJ | try4gcrpt added on April 1, 2024 | Answered

I want to know if the hairy bittercress I have shown is already too mature for using a lawnmower with a grass catcher. I apologize if this question is a repeat I am not sure if my other inquiry was received. I also am uploading what I believe to be a better picture.

It can help with the spread from seed, but the root system will continue to thrive with pruning. Selective herbicides may be the best option. I don't like to recommend chemical means, but this one will be next to impossible to get rid of.

Another thing that you can try is boiling water. Applying this to the spots every day until they are dead and do not return can help, as well.
