Someone told me you can eat certain weeds that grow in the yard. Is that so and, if so, which ones?
Yes, you can eat some weeds. This article will help:
I need a picture of the edible weed, Lamb's Quarter.
This link has a picture of the plant: http://www.veggiegardeningtips.com/surprising-lambs-quarters/
Click on the picture to enlarge it.
4' w x 5' h, 10" x 11" average leaf, looks fuzzy like elm leaf but isn't and leaf is NOT shiny.
Please send an image back attached to this email and we will try to identify it.
I read somewhere, a long time ago, that some weeds grow next to the plants that they look like as a form of protection. A friend is doubting this, and I can't remember where I read about it, so I can't prove it to her. Can you give me any info on this?
Yes, this is true. Vavilovian mimicry (also crop mimicry or weed mimicry) is just another fancy term for a defense mechanism in plants.
My dogs are getting into a plant the has arrow-shaped seed that is barbed and is on a 1/4 to 1/2 inch tightly spiral stem. I have not been able to identify the plant and have no idea what I'm looking for besides the seeds. My yard is fairly big but is mowed often.
This is called burr medic, or burr weed.
I have a weed that grows about 3 inches high and has a small red flower on it. The plant kind of grows along the ground and is spreading like crazy. It has now turned brown and is all through my front yard. Do you know what it is and how do I kill it? Thank you.
Do you have a picture of it? If you attach it to this email and send it back, we may be able to identify it.
