Fun with Roundup


As an informal experiment to determine the effectiveness of Roundup
and degree of affect on surrounding untreated flora,

  • I sprayed some today on some new, never-before-sprayed growth:
    • In one corner, two different types of flora sprayed completely.
    • In an isolated corner, one spray, not completely covering leaves
      of the growth.
    • In the center of same flora growth, completely covering leaves
      of the growth, but not touching the surrounding growths.

Isolated, lightly sprayed growth

Sprayed with just one squirt. ~3-5ml of roundup mix.

  • I start to watch progress of growths sprayed yesterday, some
    were affected more than others. One seems unaffected at all.

    after roundup, one day later. I suspect this has some roundup resistance.

About 6 to 7 days later, we have mixed results:

  • On the new, never-before-sprayed growth:

    • In one corner, of the two different types of flora sprayed completely, one is more dead than the others.
    • In the isolated corner where the growth was sprayed very lightly, it showed a little inhibition, but is still living.
    • In the center of same flora growth, the growth that was sprayed is dead, but the surrounding growth is affected , but only in a certain direction.

      These growths in the corner are mostly dead after 6 days. However one seems to be surviving.

      Isolated, lightly sprayed growth

      After the one squirt of Roundup mix, this is still alive, so you really need to cover the greenery as per instructions.

      Sprayed growth in middle.

      I suspect the root system distributed the chemicals in a certain direction — maybe towards the origin.

  • On the other growths sprayed, the one which seemed unaffected at all has withered a little bit, but probably will survive. The other growths are mostly dead, but one that seemed to be dying now seems to be recovering.

    Other growths

    This was supposedly roundup resistant, but it is dying off — but less so than the others after 7 days.

    Other growths

    Surprisingly, after 7 days, this looks healthy.
