    Is there any way to kill bluegrass in a bed of winter creeper other then hand wicking it with glyphosate? I used Fulsilade 2 and another product with the same ai. It may have stunted the bluegrass, but certainly did not kill it. Help!

    Thanks

    week applications of roundup should take care of it

    When wintecreeper starts turning purple, it is into winter dormancy - not much growth activity. Should be happening now, or soon, for you Jay. Most of mine far out of town are changed, but the ones in town are still green.

    Then, since Roundup is taken in by leaves of ACTIVELY GROWING plants, you can spray Roundup over top of the euonymous, since KBG will be actively growing for a month after euonymous is dormant. I have gone out on an unusually warm February day and successfully eliminated grass in perennial beds with Roundup. When it is colder, the visible effects of the Roundup app will take longer. I often leave cleanup of the dead grass until spring - with our snowfalls.

    Your a plant encyclopedia! Thanks! What rate do you mix your roundup at when spraying over the top? I sure don't want to kill this guys prize Winter Creeper.

    Thanks again

    First time I did it, I was planning on killing everything, so I went with the 2% rate. Happened to spray in late Oct - grass died, but wintercreeper just sat there. Figured it would die out in springtime. (On some woody and perennial plants, you don't really see Roundup damage until the next year.) But it took off great in spring.

    Have since done it a few more times, but I always tell the client that we could have damages, even severe damages. Don't ever state that it won't hurt the euonymous; if it is really bad, clients would usually just as soon kill it all and start over. If you want to be safer, grass will be easy to knock out at a 1% rate (1 oz/gal). And run a test this year - just do a small area - to give yourself confidence in using this technique.

    This use of Roundup is my own experience - probably could not get advice from Purdue plant people about it. But my former comments (& experience) on Roundup and Canadian thistle came directly from the Purdue extension ornamental specialist, in the mid 80s. Back then didn't have a web to get 20 different answers to a question, so we just went right to the people who know. I'd still prefer their ideas to a bunch of anonymous know-it-alls.

    Is your email still earthlink? If not, send me an email with current address.

    You are awsome. I trust your experience! My address is still earthlink, did you try to send something and have it returned?

    I tried going to an expert just today. I was asking an agronamist who sells fert and chemicals if Snap shot would have any adverse effects on Tulips. I can never find the instructions in the bag. Anyway he said it is not labled for Tulips, and you had to use another inferior product when around them. Guess what? I found the label in a bag I was using today, and it said not to use it in Tulip farms, but was ok to use on tulips before they reach a height of 3/4", and after they flower. So even some guys who are supposed to be experts can not be trusted. You are an expert I can trust!

    I will explain to my customer the possible ramifications of the roundup app. Jim, when does it come out of dormacy, ie. the creeper? I was thinking going 1% now, and maybe on a sunny day early spring if the creeper stays dormant longer then the grass. Just as you said, it was 90% purple. I think if I wait a week or so it will all be dormant.

    Thanks a million Jim.
