  • Do garden plants take up water through leaves?

    From John Robertson@21:1/5 to All on Wed Sep 22 00:53:34 2021

    I'm told by some that plants don't take up water through the leaves.

    While I can believe that (how would they suck up the water anyway?),
    how does female dogs pissing on weeds work to kill them?

    And roundup?

    Most plants do NOT take up water through their leaves. Some liquids,
    however, contain chemicals that penetrate the barrier against water.
    These liquids include herbicides and urine.

    The needles of coast redwoods (Sequoia sempervirens) trap moisture from
    fog. They have tiny rootlets, not on the needles but on the branches
    adjacent to the needles, which then absorb the water. In areas where
    there is little fog, coast redwoods that have been planted as part of a landscape must then be hosed down, top to bottom at least weekly.
