Puncturevine (a.k.a. Goatheads)
When we moved in to our house last year there was a lot of puncturevine. This spring we removed about 20 tons of dead sod, weeds and dirt. I tried to get all the "stickers" out but it is almsot a hopeless cause. I have picked thousands of these weeds already this year. Just today I picked over a hundred and turned around and there were more growing where I just picked! I am against using Roundup but will use anything that is organic. Does anyone have any ideas on how to get rid of goatheads besides picking them and burning them (HOA won't allow that).
I also have those darn big purple thistles but this year I have kept them under an inch in size. I just can't seem to get rid of the roots even when digging down several feet.
Any ideas would be VERY helpful.
