Weed Identification

February 3, 2017

Question: What is the plant with long root, is it a weed or maybe a poppy? The creepy viney one is what I really need to get rid of...what is it?

Charmayne
Lea County, NM




Answer:  There are two specimens in the baggie of weeds from Charmayne’s yard, one is a poppy seedling with the long tap root. It is a flower and not necessarily a weed, just depends on where it is growing.

The other creeping weed is a winter annual known as 'Chickweed'. It is an aggressive ground cover weed and has a tendency to choke out turf when not controlled. It grows low to the ground and lawn mower blades usually do not cut much of the plant off. It has pale white flowers and produces 1,000's of fine dust like seeds. Chickweed likes a cool growing season, hence it’s a winter weed. It loves to grow in shade and moist to wet areas where it will mound up.

Control Recommendation: Two methods of control outside of hand pulling it. One is using a broadleaf weed herbicide. A second control measure would be the use of a pre-emergent herbicide that targets the germinating seedlings.

Post-emergent herbicides such as a 2,4D broadleaf spray will kill this weed effectively. Just be careful and read the directions of your herbicide product for application. Your poppy seedling submitted is considered a broadleaf plant, and this herbicide would kill your poppies too.

There are several Weed and Feed products that contain 2,4D Herbicide and a fertilizer in a dry granular product that will control the chickweed and other broadleaf weeds. READ the application label and use accordingly by not over applying these types of herbicides.

A pre-emergent herbicide applied in late fall will control 1,000's of seeds dropped by the parent plants. This herbicide affects the germinating process of ALL SEEDS including those in your flowerbeds. Suggested pre-emergents herbicides -- Surflan, Pendamethlin, Balan, Preen, Barricade, Snapshot, Amaze, Scott's and High Yield turf products at local garden centers.
