miserable yellow flower weed -- identification?
This is my first time posting to Weeds. I'm trying to attache 2 photos but not sure it will work. Hopefully someone can help me. My yard and indeed the whole county seems to be overrun with this aggressive yellow flowered plant. Has fleshy rhizomes (?) and seems to take hold in any bare area or where lawn is weak. Flowers open just in sunlight, but when they do it's a field of lemon yellow!
So once I get an ID, naturally the next question is: How can I get rid of this stuff? How does it move (seed I guess, since it spreads beyond immediate area).
