What is this plant
Hi - This is garlic mustard (Alliaria petiolata), a very invasive non-native plant that alters soil chemistry and outcompetes native plants. It spreads very effectively by seeds and the seeds can remain viable in the soil for ~5-10 years. If you have had these plants in your area for awhile, it may take several years to get them under control because of the seed bank in the soil.
Refer to this fact sheet for more specific guidance on mechanical removal, https://www.invasive.org/weedcd/pdfs/wgw/garlicmustard.pdf

Thanks. I don’t recall seeing it before in my garden which is why it caught my attention. I will dispose of it as you have suggested.
