    On weeds in driveway cracks maybe black plastic cover for an hour or two would get hot enough. Gosh it is hot and humid where I live. We are just not used to this.

    Has anyone tried solar pool cover to kill grass and weeds in bark chips and so forth? This is about the same as bubble wrap, right? Or black plastic with bubble wrap on top and weighted down with a few stones or sand bags. Fold it over to fit the small garden spaces, drive-cracks or bark chip areas.

    Of course, the exhaust heat from your mower or blower is hot--just install a pipe extension--or maybe some flexible metal tubing to aim at some troublesome thistle.

    I tried straight household ammonia, as a nonselective grass and weed killer. After 5 days it seemed to work.
    Upper right--on squirt, lower right two, lower left three, upper left 4 squirts.
    Of course, there is an odor--and I would not want to get it near my eyes.

    This helps explain why pet urine kills grass.

    I don't think so, and killing plants with ammonia is like putting fires out with gasoline.

    After about a week--still killing the grass dead. If anything, slightly better.
    Time to reseed the spot.

    Suppose there will be a residual effect?
