I (foolishly) let a plant with thorns and sharp leaves get rather large next to my house. Now I'm finding it tough to tear it all out because it's so well established. Can anybody help me identify the plant so I can try to figure out if I'm killing enough of it so that it won't come back? I live in Colorado. A picture of the plant is here and a close up of the yellow flowers/leaves is here. [more inside]

So, about a year and a half ago, we bought a house! Awesome. For the first time, I have a back yard and a front yard and a lawn and... stuff, and I don't know, maybe because I'm old and boring now, I've started to give a crap about making my lawn look nice. Something is really starting to piss me off... [more inside]

What is this plant (or weed) growing in my back yard? It has multiple, thick stems with tiny thorns, green leaves that turn light green/reddish as the plant gets bigger, and a big root system with roots that are woody and slightly rubbery. It does not have any tendrils or flowers and left to grow, it begins to resemble a small tree. [more inside]
