Well, I'm down on chemicals, I only use ant poison when I have to use it, and I pour it directly down the holes. Chances are mighty slim that I'd ever use Roundup on my property... I don't want my cats chewing anything with that cr@p on it. Fortunately, I'm the kind of stubborn b@stard who tackles challenges like these goatheads, and I'm more determined than ever to knock 'em down and eventually knock 'em out. I made good progress this morning, pulling several hundred puncturevines, and about 50 were larger ones loaded with goatheads... they were the ones I missed earlier, grown to maturity with all the recent rains. No worries, I caught 'em in time, and that's what I'll keep doing, since every vine I pull or destroy means that many less goatheads on my property. I know I'll have to break out the flamethrower again pronto, as I noticed a new wave of seedlings or sprouts after the rains. These goathead vines are tough customers, lol... like the goldurned 'Terminator' they just keep a-comin', and they never quit!
