Irises sprayed with Herbacide

18 years ago

I'm wondering if any of you have ever had your plants sprayed with a herbicide like Round-Up. Our new landscapers tried gingerly to avoid my irises and other plants as they sprayed weeds in my iris beds (which they had not learned they were supposed to avoid). While the weeds shriveled up in two or three days, several days later my daylilies, geraniums and irises showed damage as well. The irises have yellowish and brown spots where I assume drops of the spray hit them. I have cut away some of this foliage, though more of it surfaces as the days roll on, I am finding.

I have had this happen once before--it was worse then, and the irises seemed to recover. This time it's on a wider scale, and many more small plants were affected.

Am I right to keep cutting away foliage, or does it really matter? Is it only the leaves that are affected and not the whole plant? Truthfully, the plants seem to be growing as they normally would this time of year. Are irises hearty enough to handle this kind of poison? I'm just wondering if anyone knows.

    Iris plants will survive inadvertent overspray. What you will notice when they bloom is what it does to the bloom. (Not a pretty sight)

    Yes, it'll probably ruin your bloom for this year, but the plants themselves should survive just fine. My guess is that by the time you actually see damage to the leaves, removing them won't help matters.

    Depending on the degree of RoundUp exposure, blooms may be properly formed but bleached white or yellow, or they may be both bleached and extremely deformed (like claws).

    As long as the plants aren't hit with herbicide again next year, they should bloom normally in '09.

    Examples - Normal & Roundup damage.




    The yellowish and brown spots you have may be just common Leaf Spot.

    I'll keep you all posted. Needless to say, I'm not pleased, but as I'd mentioned, a few years ago it happened, and the plants survived. Some of the ones this time, though, are quite small thus my real concern.

    Randy: just curious: is the second flower above "Can't Touch This" by Schreiner?

    I've had MDBs that had RoundUp dripped on them and survived just fine. You can't get much smaller than MDB rzs.

    Hi Mike,
    It's a seedling, Queen's Circle X Puccini
    It has a pretty sibling that I'm going to register a name for.

    Randy,
    That's really attractive!

    Thanks to all for your responses.

    My BIG bed out back was hit by a massive amount of herbicide. We have an empty field beside it and the new farmer didn't care where his crap went. My irises are looking horrible. The ones on the front row which took direct hits are like the irises pictures above. The ones in the middle of the bed are bleached out and plain. On one clump I have normal flowers, then totally white ones with purple specks and then lighter purple. I am really hoping that the irises at the back of the bed are better. I have straight tall bloom stalks but am waiting to see about the flowers themselves. Both of my kids lost their irises also. They were in this bed. Even the grass between the field and the iris bed is dead.
    I swear every year it is something. Last yr, the freeze, the year before tornado, the year before hail...now freaking Round UP~~~

    Wow, littlebit, it sounds like you and I are in a similar situation, looking every day for what did or didn't get affected. The very good news for me is that I am having some completely normal bloom in the midst of the plants that were affected. In fact, I am about to post some pictures of some real beauties.

    Still, the spray has affected each one of my beds, and it is sickening that someone we don't even know can just come in and in an hour or so mess up a year of hard work and preparation. I hope you'll be surprised by the plants at the back of your bed.

    Thank you Mike, I did find a bloom this morning that is normal~~Other Mary~~looks exactly like she is suppose to. Now hopefully the rest of them will be ok on that clump..Some of the irises in the back row(my daughters bed) are starting to open on short stalks..the flowers are showing some damage, but I continue to be hopeful..I will see if I can find a picture of this bed to post..
