It doesn't look too bad, right? It's green-ish, but it doesn't look at that bad. Until you get close to it:
This weed (spotted spurge) makes up the ENTIRE yard shown in the picture above. I've managed to pull it all out on the other half of the yard, but it's already starting to come back. It's so totally a losing battle. BUT! I shall win the war...it may just take a while...I'm thinking this will be like the Civil War - something that some thought would be over quickly...and 4 years later it finally ended. Maybe I should add this monster to my goals.
